PROGRAM DESCRIPTION

 

A major objective of the TAO/TRITON Array is to facilitate understanding, modeling, and prediction of global interannual climate fluctuations associated with the El Niño-Southern Oscillation (ENSO) phenomenon.  To this end, the TAO Project has implemented an ocean-atmosphere observing array in the tropical Pacific Ocean to initialize, force, and verify ocean prediction models.  The TAO/TRITON Array consists of approximately 70 ATLAS moorings and current meter moorings within 8-12 degrees of the equator and spanning the Pacific Basin from 95 W to 165 E.  Data from the array are both internally recorded and reported in real-time via Service Argos.  The array is being maintained under sponsorship of NOAA’s Environmental Research Laboratories as part of the ENSO Observing System for NOAA’s Seasonal-to-Interannual Climate Prediction Program.

2.0  OPERATIONS

 

The cruise track and details of station work are summarized in Appendices A and B.  The cruise will involve underway operations (Section 2.01) between stations, including  CTD/water sampling stations (Section 2.02), mooring recoveries, deployments, and repairs (Section 2.03).  During the cruise, it is requested that the vessel provide to the Chief Scientist an updated operations spreadsheet (similar to Appendix A) with actual times and speeds made good for the entire cruise.  The TAO project will provide regular updates of buoy positions during the cruise in order to recover those adrift.

                                               

2.01      Underway Operations

 

2.01.1  ADCP (Firing)

 

A ship-mounted ADCP system will be used to continuously measure the currents in the upper ocean along the trackline. At a minimum, data from the ADCP will be logged from the start of the transit once in international waters (or waters for which there is research clearance) and continue until leaving international waters.  For calibration purposes it is essential that bottom tracking be activated at the start and end of a cruise when in water depths shallower then 500m.  The ship's Electronics Technician will be in charge of data storage (hard drive to disks and/or CD’s as necessary).  The ADCP will be interfaced to the ship’s GPS receiver and will receive data at one second intervals.  The clock on the ADCP IBM computer will NOT be reset while underway.  ADCP operating parameters will not be changed without the permission of the Chief Scientist; in consultation with Dr. Eric Firing, and after informing TAO personnel of the intended parameter change.  All ADCP data will be provided to the chief scientist and sent to Dr. Eric Firing at the University of Hawaii.

 

Accurate ship navigation is essential for valid ADCP current measurements.  The ship will provide a fully operational GPS receiver and Seapath 200 system (or equivalent) for navigation input.  Ship’s ET will select proper GPS codes to enable ADCP navigation data collection.  The ADCP will be interfaced with the ship's gyro so that accurate heading information is available to the ADCP.   A  manual comparison of the ADCP heading/gyro reading will be logged by the Electronics Technician while the ship is dockside, at the beginning of a cruise and checked periodically throughout the cruise. For calibration purposes, “Bottom Tracking” should be activated whenever the ship is transiting water shallower than 500m.

 

Due to compatibility problems, the ADCP is not interfaced to SCS, so GPS navigation and gyro inputs must be connected directly to the ADCP system.  If the ADCP becomes interfaced to the SCS, then the ADCP data will be recorded on both the ADCP recording system and the SCS.  Appropriate data storage systems will be connected to the ADCP system for ADCP data collection.  The ADCP data recorded on the IBM has course and speed information from the navigation data which is exactly time coincident with the ADCP ensembles.

 

The ADCP system will be operated by ship personnel and will continuously log data to the ADCP zip storage disks during the entire cruise.  If necessary, the ADCP data disks will be changed when full.  Full disks will be labeled and backed up.  An ADCP log will be maintained by the Electronics Technician and a check of the ADCP recording of heading, time, velocity and navigation information will be done periodically to ensure the system is operating properly.  Any inconsistencies, such as heading, time, and/or navigation input not in agreement with actual/expected, will be noted in the log and reported to the Commanding Officer and Chief Scientist.

2.01.2  SST and SSS

Sea surface temperature and salinity will be recorded continuously with a SEABIRD SBE-21 accurate to within 0.1 C and 0.01 psu.  The Survey Technician will translate the data from the thermosalinograph to ASCII.  It is the vessel’s responsibility to ensure that the thermosalinograph is calibrated, at a minimum, annually.

 

2.02      CTD Observations

A Sea-Bird 9 plus CTD with dual temperature and conductivity sensors will be the primary system and will be provided by the program.  An oxygen sensor will also be provided for the primary system.  A backup Sea-Bird 9 plus CTD with dual sensors is also required and will be provided by the ship.  A Sea-Bird carousel and twelve 10-liter Niskin bottles will be used to collect water samples for the analysis of salinity.  A backup Sea-Bird carousel and spare Niskins will be provided by the program.

 

At a minimum, 1000 meter CTD casts shall be conducted at each mooring site between 8N and 8S for sensor inter-comparison purposes.  As time permits, additional or deeper CTD's should be conducted whenever addition of the CTD’s will not impact scheduled mooring work.  For example, if the ship would arrive at the next mooring site in the middle of the night, it is preferable to do CTD’s on the way, rather than remain hove to waiting for daylight.  Another example would be when mooring operations are significantly ahead of schedule.  Note that for moorings with subsurface conductivity sensors, primarily located along 95W and 110W, two additional profiles should be collected prior to the mooring recovery for sensor calibration purposes if time is available.  The additional casts will be to 200 m and only two salinity samples will be collected, one at 200 m and one in the surface mixed layer to be determined from the downcast profile.  The usual 1000 m or deep CTD with 12 salinity samples collected should be done after the new mooring deployment.  These 3 casts should be spaced around the mooring site and not all in the same place.

 

Beyond those at mooring sites, CTD's should be conducted in the following order of priority:

 

1000m CTD’s at one degree latitude intervals between 12N and 8S , along the ship's trackline. 

 

Extend 1000m CTD’s at mooring sites to a minimum of 3000m or a maximum depth of 200m from bottom.

 

      1000m CTD’s every one-half degree of latitude between 3N and 3S

 

If the time required for a CTD would cut into the required daylight hours for a mooring operation or would delay the ship from arriving in port on schedule, the Commanding Officer may omit a CTD, after consulting with the Chief Scientist.

 

For each cast, the CTD operator should be notified at least 30 minutes prior to arriving on station in order to ready the underwater package and power up the instrumentation (i.e. turn on the deck unit) giving the electronics time to equilibrate.  The data acquisition program and VCR should be started just prior to deployment. 

 

Once the CTD has been deployed, it should be held at 10 m for 2 minutes to activate the pumps and remove any air bubbles in the sensor tubing.  The winch operator should then raise the package to just beneath the surface being careful to not let the sensors come out of the water. The CTD operator will hit “markscan” and then instruct the winch operator to start down. 

 

Descent rates should be 30 m/min from 0-50 m, 45 m/min from 50-200 m, and 60 m/min beyond 200 m.  An entry in the Marine Operations Abstract should be made for each CTD cast at the maximum cast depth by the bridge watch.  Ascent rates should not exceed 60 m/min.  If possible, all 12 Niskin bottles should be closed at specified depths in the water column.  After recovery and data acquisition is completed,  the deck unit should be turned off.

 

CTD data will be acquired and processed on the ship’s computer equipped with SEASOFT software.  The capability to display CTD data using the SCS system and monitors will be available. The CTD operator will complete the CTD cast logs.  The CTD operator or bridge watch will maintain the CTD weather log.

 

Water samples for salinity analysis will be taken from each Niskin bottle on every cast (or as specified by the Chief Scientist).  The Survey Technician will run salinity analysis on the ship's autosalinometer within 2-3 days after the samples are collected using ACI2000 software.  The autosalinometer will be standardized with IAPSO standard seawater, provided by the program, before each salinity run.  Bottle salinity data will be used post-cruise at PMEL for conductivity sensor calibration.

 

In order to reduce the cost of standard water needed to calibrate CTD data, the number of salinity samples has been reduced.   PMEL proposes taking 8 samples per station instead of 12; not sampling half degree stations; and running 40 samples per standard instead of 36.   Questions regarding these revised procedures should be directed to Kristy McTaggart.

 

The Chief Scientist in consultation with the FOO will set a cruise CTD operator schedule for the science party to assist and cover 24 hour CTD operations as needed relative to the CST’s workload.

2.03  Mooring Operations

 

Mooring Operations are scheduled to be conducted as shown in Appendix A.  Operations will be conducted from 8S - 95W to 12N - 95W and then to 8N - 110W thence to 8S - 110W.  The following mooring operations are anticipated, though the work may be changed by direction of the Chief Scientist; in consultation, with the Commanding Officer.

2.04                  Navigation

Navigation will be based on the best available information, including GPS, dead reckoning, radar and visual bearings as appropriate.  GPS is vital to the efficient deployment of a mooring and is the preferred navigational aid in the project area.  Radar ranges and visual bearings to buoys may be required during deployment and recovery operations.

 

Navigational information will be recorded on the Marine Operations Abstract (MOA) by the bridge watch.  In addition to recording mooring events as they occur, various courses and speeds may be logged when on station.  In the event of an SCS failure, the bridge watch will record hourly GPS positions in the MOA.

 

2.05                  Sea Beam

Sea Beam swath surveys are requested for all mooring sites of this cruise as defined above. The center beam information of the Sea Beam system will be used to observe and record bottom depth for this and future mooring deployments.  The Chief Scientist will provide areas and coverage parameters for the surveys relative to time available as the cruise progresses. Contoured plots of mooring site surveys will be generated by the Chief Survey Technician.

 

2.06  Underway  Measurements in support of Global Carbon Cycle Research (GCC) (Feeley,  Wanninkhof)

 

2.06.1 Request:

As part of the ongoing research to quantify the CO2 uptake by the world's oceans we have installed underway systems on BROWN.  After initial start-up, which requires about one hour of monitoring, the system needs checking twice a day requiring a total of about 20-minutes.  We would also request weekly data downloads and transmission such that we can perform on shore near-real-time quality control to assess if the instrument is operating satisfactorily.    All costs of the email transmissions and survey technician overtime would be covered by AOML.  The chief survey technician, J. Shannahoff, has operated the instrument before with good results. In the event of system malfunction that cannot be easily repaired, we will ask Mr. Shannahoff to shut the system down.  The shoreside leader of the effort, Mr. Robert Castle has interacted closely with J. Shannahoff and feels that this arrangement would work well.

 

2.06.2  Introduction:

The underway sensors on RHB will be used in support of the objectives of the Global Carbon Cycle Research (GCC) to quantify the uptake of carbon by the world's ocean and to understand the bio-geochemical mechanisms responsible for variations of partial pressure of CO2 in surface water (pCO2).   This work is a collaborative effort between the CO2 groups at AOML and PMEL.

 

Principal investigators:

      Dr Rik Wanninkhof, AOML              305-361-4379             Rik.Wannikhof@noaa.gov

 

      Dr Richard Feely, PMEL                 206-526-6214             Richard.A.Feely@noaa.gov

 

The semi-automated instruments are installed on a permanent basis in the hydrolab of RHB and are operated by personnel from AOML and PMEL.   All work is performed on a not-to-interfere basis and does not introduce any added ship logistic requirements other than the continuous operation of the bow water pump and thermosalinograph.  This effort requires one permanent berth for the operator of the systems.  The instrumentation is comprised of an underway system to measure pCO2, a SOMMA (single operator multi-parameter metabolic analyzer) -coulometer system to measure total Dissolved Inorganic Carbon (DIC),  - a Turner Designs fluorometer, and a YSI oxygen probe. An oxygen titrator and stand-alone fluorometer will be used to calibrate the underway oxygen and fluorometer, respectively. All the instruments are set up along the port side bulkhead and aft bench in the hydrolab.  The batch oxygen and DIC samples will be analyzed in AOML. 

 

 

2.06.3 Rationale:

Current estimates of anthropogenic CO2 uptake by the oceans range from 1 to 2.8 Gigatons per year.  The CO2 fluxes between air and water are poorly constrained because of lack of seasonal and geographic coverage of delta pCO2 (the air-water disequilibrium) values and incomplete understanding of factors controlling the air-sea exchange of carbon dioxide.  Seasonal and temporal coverage can be increased dramatically by deploying pCO2 analyzers on ships.

 

The effort on RHB is expanded beyond the historical scope of the underway programs by incorporating additional sensors to improve our understanding of the factors controlling pCO2 levels.

 

2.06.4  Sensor Suite and Maintenance:

 

2.06.4.1  Underway pCO2 system

This system consists of a large (40-liter) air-water equilibrator requiring an unobstructed drain at floor level for the 15 L/min outflow, an infra red analyzer with valves and flow meters, and a computer controlling the operating sequence and which also logs the data.  The underway pCO2 system is an integrated package for measurement of pCO2 in air and water and support sensors necessary to reduce the data (such as equilibrator temperature, location, salinity, sea surface temperature and barometric pressure).  This system is an upgrade from the initial systems and requires routine checks at 6-12 hour intervals, including logging of mercury thermometers in the equilibrator.

 

2.06.4.2  Oxygen sensor

This is a compact pulsed electrode unit which also contains a temperature sensor.  This is a new sensor built by Dr. Langdon at LDEO.  Water requirement is 2-Liter/minute with a bench top drain. One foot of bench space is required. During this cruise the data will be validated against samples taken four times a day and analyzed by potentiometric winkler titrations.

 

2.06.4.3  Turner Designs Fluorometer

This instrument, which was jointly purchased by AOML and AMC for BALDRIGE, requires a water throughput of about 5 L/min.  Periodic cleaning of the flow through cell (2-14 days) is required .  The signal of the fluorometer is logged on the shipboard SCS system or on the computer logging the underway pCO2 data.  Aliquots of seawater are extracted twice per day and analyzed for chlorophyll and phaopigments on a separate fluorometer following routine procedures  to calibrate the fluorometer signal.  This information will be particularly useful to extrapolate the observations from the NASA SEAWIFS satellite to in situ pigment concentrations.

 

2.06.5   Summary - Ship infrastructure support:

 

2.06.5.1  Continuous seawater supply: 20 lpm minimum, 40 lpm maximum for instruments, and 75 lpm throughput to assure short residence time of water in line and minimal heating.

 

2.06.5.2  Access to TSG and SCS data: Temperature at intake, salinity from TSG, fluorometer signal, wind speed (true and relative), wind direction (true and relative), time, latitude, longitude, and ship speed.

 

2.06.5.3  Bench space, hydrolab space, access to bow water line and drains.

2.07  Underway CIRIMS skin temperature device

 

The CIRIMS design goal is to provide ocean skin temperature data with an accuracy of +/- 0.1 °C from a system that has the ability to run autonomously at sea for extended periods with no involvement from the vessel crew.  The CIRIMS design incorporates two Heitronics infrared KT11 radiometers with a spectral bandwidth in the 9.6-11.5 μm range. One radiometer is housed within the unit itself and measures sea surface radiance. The second radiometer is housed externally in an enclosure and measures sky radiance. Reliable calibration of the internal radiometer is achieved by two-point calibration using a modified Hart Scientific microbath. A custom designed, copper cylindro-cone blackbody is immersed in a water/ethylene glycol solution within the temperature-controlled microbath. Two calibration points are set a few degrees above and below the scene temperature allowing for dynamic calibration over a wide

 range of scene temperatures.  The temperature-controlled housing provides a stable, dry environment for the internal radiometer and the blackbody. The insulated housing is heated and cooled by a thermoelectric heater/cooler unit, which maintains the internal case temperature to within +/- 0.5 °C of the set point, generally 35 °C.  Protection of the radiometer and blackbody is arguable the most challenging and debated aspect of a practical design. We have chosen to use an  IR transparent window to provide complete protection under all conditions. This approach relies on our ability to correct for the effect of the

window. The external housing contains the IR transparent window and an external heated blackbody. Since the window is not perfectly transparent, the effect of the transmission, emission, and reflectance of the window on the measured radiance must be determined. In order to quantify the effect of the window, a two-point hot blackbody has been mounted on the back of the door of the external housing. The door of the housing is closed, protecting the internal components, and measurements are made of the heated blackbody with and without the window. In this way we are able to correct for the window effect.

 

 Two through-the-hull instrument ports are installed on the Brown at depths of 2 m and 3 m below the mean still water line. The ports are located directly  above the ship's existing 5 m intake port in the bow thruster room. The ports have been  instrumented with two SeaBird model SBE-39 Temperature/Pressure sensors to provide temperature at depths intermediate between the ship's standard intake depth of 5 m and the CIRIMS skin SST.

2.08   Atmospheric Soundings (Bond)

PACS is sponsoring a project to resume atmospheric soundings during buoy operations in the eastern equatorial Pacific.  The primary data collection will consist of four soundings a day (nominally at 0000, 0600, 1200 and 1800 Z) while along the 110EW and  95EW transects between 8EN and 8ES.  The region of greatest interest is between about the equator and 5N along each line.  Twice-daily soundings (at 0000 and 1200 Z) will be collected on the day prior to arriving at 8EN, 110EW , the day after departing 8EN, 95EW, and during the transit from 8ES, 110EW  to 8ES, 95EW.  These soundings can be collected either while the ship is on station or underway.  The soundings will be made using a Vaisala receiving station which will be installed prior to the cruise, following standard launch procedures.  Since it is the lowest portion of the atmosphere that is of greatest interest, any sonde that reaches as high as 500 mb will be considered successful.   Personnel form ETL  will carry out the launches.  It is  recognized that this work is to be carried out on a not to interfere basis with the primary project.

2.09                  Environmental Technology Laboratory (Fairall)

 

2.09.1  ETL Systems and Responsibilities

The Environmental Technology Laboratory (ETL) flux system includes a variety of bulk meteorological sensors, radiative fluxes,and  cloud ceilometer.   Jeff Hare will be responsible for the installation.  

 

The ETL flux system is set up on the jack staff and bow tower (See Appendix E and F).  Fast turbulence sensors are mounted on the jack staff; flux radiometers, the ETL STI rain gauge, and data loggers are mounted on the AOML bow tower. Signal and power cables are from the bow tower to the main lab thru the 02 deck hull penetration.  ETL flux data will be logged on an HP-UX workstation in the main lab.

 

2.09.2  Science Party Laboratory and Work Space

Laboratory/work space in the main lab and bio lab are needed by ETL primarily for instrument data systems whose sensors are positioned outside.  One unit of computer space is defined as counter-top space 2 feet wide, 30 inches deep, and 3 feet high.  Required space: 

 

         Sensor                 Sensor Location             Best Lab       Units Needed      Station Type

         Ceilometer            02 or 03 Deck                    Bio                    1                      PC

         Flux System         Jack Staff/Bow Tower         Main                 3               2HP-UX, 1PC

 

2.09.3  Ship infrastructure support:

ETL will require an RS-232 data stream from the ship’s SCS at a rate of 2 seconds for realtime logging on the flux HP-UX system in the main lab.  This will consist of navigational information (ship’s P-code GPS, ship’s gyro, ship’s Doppler log) and some meteorological/oceanographic data (thermosalinograph water temperature, some IMET data).  This will be the same event used on the JASMINE, NAURU99,  KWAJEX, and fall-01 and fall- 02 TAO cruises.

 

2.09.4  ETL flux System Operations

These systems all take measurements continuously; they will be monitored by Jeff Hare.  The major operational aspects of these systems are moving blocks of data for archiving, preliminary processing for data quality assessment, routine calibration checks, and cleaning of optical surfaces on the fast humidity sensor.   We will take periodic readings of ambient T/RH from the bridge or 02 deck using an Assman psychrometer and a Vaisala handheld calibration reference.  The Ophir hygrometer has exposed optical surfaces that accumulate salt particles generated by oceanic whitecaps.  This causes contamination of the water vapor.  The contamination can be reduced by rinsing with fresh water.  A water hose has been rigged up the jack staff to a set of sprayers on the instrument.  This allows a fresh water rinse of the optical sensor surface without climbing the jack staff.

 

2.09.5  ETL Remote Sensor Operations

These systems are engineered to operate continuously and unattended except for data storage media exchanges.   The microwave radiometer will be calibrated during clear conditions by performing ‘tip curves’ where the reflector is tilted to receive radiation from several different zenith angles.  The ceilometer will produce screen images of recent measurements.

 

2.09.6  C-band Doppler Radar Operations

The C-band radar on board RHB will be placed in an operational status. During the cruise it will be operated continuously; if possible, once the ship reaches international waters.  Raw radar data will be archived onto the DAT tape drive in the pilot house.   The scan strategy will involve either low level, long range surveillance scans or 3D volume scans of radar reflectivity and radial velocity (Hare).

 

2.09.7  Satellite Receiver

Satellite images from polar orbiting and geostationary satellites provided by the ship Sea Space system will be archived by Ryan/Falls for post-cruise processing and analysis.

        

2.09.8 Wind Profiler

ETL will require data from the newly installed 915 MHz wind profiler.  Acquisition modes will be set in Miami.  Gary Wick will be responsible for underway operations.

 

2.09.9 W-band Doppler Radar

 

During the TAO 2004 cruise, the Radar Meteorology Group of the University of Miami will deploy on the Ronald H Brown a portable and lightweight cloud radar operating at 94-GHz. 94 GHz is the higher frequency used in radars for atmospheric research. The radar will be deployed on the deck of the RB, near the NOAA/ETL Portable Observatory container and the NOAA/ETL flux system container. The radar is no more that 1,5 m long and 0.5 m wide and when sitting on its mounting base is less than 1 m tall. The power requirements are very small (a commercial 28 Volt, 3.5 Am power supply is required) and two computers, one that hosts the digital receiver and another for radar data post processing and archiving will be store in the Portable Observatory container of NOAA/ETL. The radar system has no scanning capability, will be looking only vertically and it has very low output power.

 

The digital receiver of the radar was recently upgraded (14-bit A/D) and the radar is capable of high temporal resolution data collection (0.5-2 sec). The radar transmits a FM Continuous Wave at 94-GHz and the sweep (ramp) frequency can be anywhere between 15-60 MHz. The FMCW principal allows for very fine vertical resolution (5-15 m). Currently, we are working the final detail of a post-processing system that will tide with the digital receiver and will allow the real-time processing of the Doppler spectra collected from the radar. Our goal is to run the radar continuously during the TAO cruise.

Two graduate students are working currently on the project and will be on board the Brown during the cruise. The gr. students will be able to participate to other research activities on the RB (e.g. launch radiosonde, analyze data from other instruments, present radar data).

 

The radar will be install on the RB next week at Miami during the short stop of the research vessel at the miami port. We will tear down the system at the end of the WHOI maintenance and replacement cruise ('stratus" cruise), on Dec 23-24, 2004. We will attempt to ship the container of the radar (quite small) back to USA from Valparaiso, Chile.

 

Our research objectives are: (i) operate the radar in various configuration in the tropics and subtropics and evaluate its potential for boundary layer studies. After all, it is the first and experimental version of this type of radar. (ii) collect high resolution observations of BL clouds and study the cloud interface near the inversion. (iii) compare the data collected from the 94-GHz FMCW with radar observations from the NOAA/ETL 35-GHz cloud radar. This comparison will provide valuable insights on the use of dual wavelength observation for the retrieval of cloud microphysical properties, and (iv) study the cloud morphology over a wide region from the tropics to the subtropics and monitor the transition from the deep tropical convective systems to shallow stratus clouds in the SE Pacific.

2.11  Underway Seawater DMS Measurements - PMEL
 
Surface seawater DMS (dimethylsulfide) measurements will be made during the TAO Equatorial Pacific cruise using the PMEL automated seawater DMS system.  The surface seawater DMS measurements are used to calculate the flux of biogenic sulfur to the atmosphere for use in global climate models.  
 
The system will be mounted on and above the port side counter that is just forward of the underway CO2 system in the Hyro lab.  The system requires:
§         access to the ship’s seawater sampling line.  The system will draw approximately 100 ml of seawater from the line every 30 minutes, 
§         3 (minimal) or 4 (preferred), 120 volt circuits, and 
§         ship's compressed air (approximately 1 cfm at 60 psi or greater - the DMS system has an air compressor, but it kicks in only in the event that the system loses ship air).
§         a connection to the ship’s computer network.  
 
The system will be monitored during the cruise by University of Hawaii personnel.

2.12  University of Washington, APL Float

One ``Lagrangian Float" will be deployed at the equator at 125W after the mooring is serviced. The floats are designed and constructed at the Applied Physics Laboratory, University of Washington, Seattle. The float will drift at the base of the mixed layer for 3-6 months and measure the rates of mixing by measuring its own depth, temperature and salinity. The float will surface daily to transmit its data via Iridium and receive commands. Similar floats will be deployed at 110W and 125W over the next 18 months to monitor the effect of mixing in bringing cold water up into the cold tongue.  Drifter is similar to Argo float, both in size and deployment technique .

Personnel assigned to ancillary projects and participating in the cruise, may be assigned additional scientific duties in support of the project by the Chief Scientist.

 

Synoptic weather reports will be handled in accordance with NC Instruction 3142D, SEAS Data Collection and Transmission Procedures.

 

6.0  HAZARDOUS MATERIALS

 

RHB will operate in full compliance with all environmental compliance requirements imposed by NOAA.  All hazardous materials/substances needed to carry out the objectives of the embarked science mission, including ancillary tasks, are the direct responsibility of the embarked designated Chief Scientist, whether or not that Chief Scientist is using them directly.   RHB Environmental Compliance Officer will work with the Chief Scientist to ensure that this management policy is properly executed, and that any problems are brought promptly to the attention of the Commanding Officer.

 

6.1  Material Safety Data Sheet (MSDS)

All hazardous materials require a Material Safety Data Sheet (MSDS).  Copies of all MSDS’s shall be forwarded to the ship at least two weeks prior to sailing.  The Chief Scientist shall have copies of each MSDS available when the  hazardous materials are loaded aboard.  Hazardous material for which the MSDS is not provided will not be loaded aboard.

 

6.2  HAZMAT Inventory

The Chief Scientist will complete a local inventory form, provided by the Commanding Officer, indicating the amount of each material brought onboard, and for which the Chief Scientist is responsible.  This inventory shall be updated at departure, accounting for the amount of material being removed, as well as the amount consumed in science operations and the amount being removed in the form of waste.

 

6.3  HAZMAT Locker

The ship’s dedicated HAZMAT Locker contains two 45-gallon capacity flammable cabinets and one 22-gallon capacity flammable cabinet, plus some available storage on the deck.  Unless there are dedicated storage lockers (meeting OSHA/NFPA standards) in each van, all HAZMAT, except small amounts for ready use, must be stored in the HAZMAT Locker.

 

6.4  HAZMAT Spill Response

The scientific party, under the supervision of the Chief Scientist, shall be prepared to respond fully to emergencies involving spills of any mission HAZMAT.  This includes providing properly-trained personnel for response, as well as the necessary neutralizing chemicals and clean-up materials.  Ship’s personnel are not first responders and will act in a support role only, in the event of a spill.

 

6.5  Responsibilities

The Chief Scientist is directly responsible for the proper handling, both administrative and physical, of all scientific party hazardous wastes.  No liquid wastes shall be introduced into the ship’s drainage system.  No solid waste material shall be placed in the ship’s garbage.

7.0  MISCELLANEOUS

 

·         Phosphoric acid is unusually destructive to nylon, causing a dramatic reduction in the strength of this material used in the surface mooring systems.  Because many of the rust removing compounds used on the ships contain large amounts of phosphoric acid, it is requested that extreme care be taken to protect any nylon that is stored on deck when chemical rust removal is undertaken.

 

·         The glass balls used on some of the moorings are, as the name implies, made of glass.  They should be  handled gently to prevent damage.

 

·         Some scientific equipment is sensitive to radio frequency interference.  If interference with this or other equipment occurs, it may be necessary for the Chief Scientist and the Commanding Officer to adjust operations and transmission times or take other steps to electronically isolate the equipment.

 

·         All SCUBA diving, if conducted, shall be in accordance with NOAA, NMAO, and MOC directives.

 

·         Fouling of instruments or other damage to instrumented moorings that are expected to operate unattended for many months are of considerable concern to the Project.  To minimize the risk, ship operations such as XBT and CTD casts shall be conducted not less than one nautical mile from any mooring.  With the consent of the Chief Scientist, recreational fishing shall be allowed within the one mile range, only when the mooring is being recovered.

 

·         There will be no charge for meals. Commissioned officers who are participating as scientific personnel will be charged at commissioned officer's rate in accordance with Title 37, U.S.S. Section 302 based upon the established monthly Basic Allowance for Subsistence (BAS).

 

7.1  Small Boat Operations

Small boat operations are weather dependent and at the Command’s discretion.

 

7.2  Pre and Post Cruise Meetings

A pre-cruise meeting between the Commanding Officer and the Chief Scientist will be conducted either on the day before or the day of departure, with the express purpose of identifying day-to-day project requirements, in order to best use shipboard resources and identify overtime needs.

 

7.3  Scientific Berthing

The Chief Scientist is responsible for assigning berthing for the scientific party within the spaces approved as dedicated scientific berthing.  The ship will send stateroom diagrams to the Chief Scientist showing authorized berthing spaces.  Post cruise, the Chief Scientist is responsible for returning the scientific berthing spaces to the condition in which they were received; for stripping bedding and for linen return; and for the return of any room keys which were issued.

 

The Chief Scientist is also responsible for the cleanliness of the laboratory spaces and storage areas used by the science party, both during the cruise and at its conclusion prior to departing the ship.

 

In accordance with NC Instruction 5255.0, Controlled Substances Aboard NOAA Vessels, dated 06 August 1985, all persons boarding NOAA vessels give implied consent to comply with all safety and security policies and regulations which are administered by the Commanding Officer.  All spaces and equipment on the vessel are subject to inspection or search at any time.

 

7.4 Medical Forms & Emergency Contacts

The NOAA Health Services Questionnaire must be completed in advance by each participating scientist. Scientists are required to be medically approved by NOAA Marine Operations Center Atlantic prior to sailing should reach the ship no later than 1 week prior to the cruise. This will allow time to medically clear the individual and to request more information if needed. We ask that all personnel bring any prescription medication they may need and any over-the-counter medicine that is taken routinely (e.g. an aspirin per day, etc.). The ship maintains a stock of medications aboard, but supplies are limited and chances to restock are few.

 

Prior to departure, the Chief Scientist will provide a listing of emergency contacts to the Executive Officer for all members of the scientific party, with the following information: name, address, relationship to member, and telephone number.  These can be combined with the NOAA Health Services Questionnaire.

 

7.5 Shipboard Safety

A discussion of shipboard safety policies is in the “Science User’s Guide” which is available on RONALD H. BROWN and is the responsibility of the scientific party to read.  This information is also available on the ship’s web page: www.moc.noaa.gov/rb/science/welcome.htm.  A meeting with the Operations Officer will be held for the scientific party at the beginning of the cruise which will include a safety briefing.  Wearing open-toed footwear (such as sandals) outside of private berthing areas is unsafe and is not permitted.  All members of the scientific party are expected to be aware of shipboard safety regulations and to comply with them. 

 

7.6  Wage Marine Day-Worker Working Hours and Rest Periods

Chief Scientists shall be cognizant of the reduced capability of RHB’s operating crew to support 24-hour mission activities with a high tempo of deck operations at all hours.  Wage marine employees are subject to negotiated work rules contained in the applicable collective bargaining agreement.  Day-workers’ hours of duty are a continuous eight-hour period, beginning no earlier than 0600 and ending no later than 1800.  It is not permissible to separate such an employee’s workday into several short work periods with interspersed non work periods.  Day-workers called out to work between the hours of 0000 and 0600 are entitled to a rest period of one hour for each such hour worked.  Such rest periods begin at 0800 and will result in no day-workers being available to support science operations until the rest period has been observed.  All wage marine employees are supervised and assigned work only by the Commanding Officer or designee.  The Chief Scientist and the Commanding Officer shall consult regularly to ensure that the shipboard resources available to support the embarked mission are utilized safely, efficiently and with due economy.

 

7.7  Communications

The Chief Scientist or designated representative will have access to ship's telecommunications systems on a cost-reimbursable basis.  Where possible, it is requested that direct payment (e.g. by credit card) be used as opposed to after-the-fact reimbursement. Ship's systems include:

 

7.7.1  INMARSAT-B

INMARSAT-B, for high speed data transmission, including FTP, and high quality voice telephone communications. Costs is approximately $5.00 per minute for voice or fax, and may be charged to credit card (preferable) or otherwise reimbursed.   Phone numbers for ship's INMARSAT-B are: ###-336-899-620 voice and ###-336-899-621  fax.  (### = Ocean Code). 

 

7.7.2  INMARSAT-M

INMARSAT-M, for voice telephone communications and 2400 baud data transfer, about $3 per minute to the US. Phone number for ship's INMARSAT-M system is ###-761-266-581. INMARSAT-M may be charged to credit card, collect, or otherwise reimbursed. (### = Ocean Code).

 

NOTE:

For RB-04-11 cruise, the ship will be operating in range of the Pacific Ocean Satellite, with ocean code = 872 or Atlantic Ocean Satellite (West) with ocean code = 874.

 

7.7.3  E-Mail

An account on Lotus cc:Mail for each embarked personnel will be established by the shipboard electronics staff. The general format is:

 

      Firstname.Lastname.atsea@rbnems.ronbrown.NMAO.noaa.gov

 

Due to the escalating volume of e-mail and its associated transmission costs, each member of the ship's complement (crew and scientist) will be authorized to send/receive up to 15 KB of data per day ($1.50/day or $45/month) at no cost. E-mail costs accrued in excess of this amount must be reimbursed by the individual. At or near the end of each leg, the Commanding Officer will provide the Chief Scientist with a detailed billing statement for all personnel in his party.  Prior to their departure, the chief scientist will be responsible for obtaining reimbursement from any member of the party whose e-mail costs exceed the complimentary entitlement.

7.8  Port Agent Services/Billing

Contractual agreements exist between the port agents and the commanding officer for services provided to NOAA Ship RONALD H. BROWN. The costs or required reimbursements for any services arranged through the ship's agents by the scientific program, which are considered to be outside the scope of the agent/ship support agreement, will be the responsibility of that program. Where possible, it is requested that direct payment be arranged between the science party and port agent, as opposed to after-the-fact reimbursement to the ship's accounts.

 

7.9  EEZ Research Clearances

 

PMEL/TAO has requested and has been granted research clearances for Ecuador and France (Clipperton Island) waters only.  UNCLOS III requires that coastal states provide permission prior to conducting research in their EEZ.  All TAO and ancillary projects will comply with these regulations.

Equipment testing of underway systems may occur, but data cannot be saved while in waters of non-clearance countries.

 

8.0  Safety

 

Safety of operations is of utmost importance.  Scientists will attend all safety briefings as required by the vessel Command.
