Cruise Description and Objectives:
The Fisheries-Oceanography Coordinated Investigations (FOCI) program is a joint effort by scientists at PMEL, AFSC, and several academic institutions, to understand the biological and physical processes which cause recruitment variability of commercially valuable fish and shellfish stocks in Alaskan waters. The Bering Sea FOCI program is presently studying the effects of the biotic and abiotic environment on the early life stages of walleye pollock spawned in the eastern Bering Sea. There are two aspects to the study: the acquisition and analysis of time-series data, and specific research topics to be covered on a cruise-by-cruise basis.
The main objective of this cruise is to recover surface moorings and deploy subsurface moorings in the Bering Sea. In addition, subsurface moorings will be recovered in the Gulf of Alaska.
1.1. Chief Scientist: William Parker (PMEL) 526-6180
The Chief Scientist has the authority to revise or alter the technical portion of the instructions as work progresses provided that, after consultation with the Commanding Officer, it is ascertained that the proposed changes will not: (1) jeopardize the safety of personnel or the ship; (2) exceed the overall time allotted for the project; (3) result in undue additional expenses; (4) alter the general intent of these project instructions.
1.2. Participating Scientists:
William Parker M/USA NOAA/PMEL
Carol DeWitt F/USA NOAA/PMEL
Dave Kachel M/USA NOAA/PMEL
1.3 Ship Operations Contact:
Mr. Larry Mordock
(206) 553 - 4764
1801 Fairview Ave. East
Seattle, WA 98102-3767
Mooring operations in the Bering Sea will include deployment of two (2) subsurface moorings, two (2) TRAP moorings and recovery of two (2) surface moorings, two (2) TRAP moorings. In the Gulf of Alaska five (5) subsurface are to be recovered. All of these moorings to be recovered were deployed by the Miller Freeman during 1996. A continual dialogue between scientific and ship's personnel will be especially important to complete these mooring operations.
To insure fulfillment of all the scientific objectives, the ship will steam at maximum cruising speed whenever time in transit and between stations is greater than one hour. A standard oceanographic watch will be utilized which consists of a winch operator, a scientific staff of two and a Survey Tech on deck. Operations will be conducted 24 hours a day.
2.1. Summary of Activities
The order of mooring operations will depend on weather and light conditions. Subject to change, at the Chief Scientist's discretion, the mooring operations will proceed as follows: F-96BS-4 subsurface deployment, F-96BSM-3 surface mooring recovery, F-96BS-3T TRAP ( Trawl Resistant ADCP Platform ) recovery/deployment, F-96BSM-2 surface mooring recovery, F-96BS-2C subsurface deployment, F-96BS-2T TRAP
(Trawl Resistant ADCP Platform ) recovery/deployment, TNG Dutch Harbor, recoveries of F-9618, F-9616, F-9601, F-9602, F-9603. CTDs will be taken at each mooring site along with additional CTD lines to be added as time permits. Table 1 contains a draft copy of the mooring deployment positions.
The Bering Sea moorings will be loaded onto the Miller Freeman in Seattle If available before the July sailing. These consist of four (4) subsurface moorings, including two TRAPs.
A CTD cast will be conducted at each mooring site after deployment. If the paired surface and subsurface moorings are positioned greater than 1 mile apart, a CTD cast will be performed at both mooring positions.
2.3. CTD / Water Sample Operations
PMC's Sea-Bird CTD will be the primary system used. (PMEL's CTD stand, which has been modified for the attachment of a Sea-Tech fluorometer, will be used). CTD data will be acquired on a PMEL computer using SEASOFT software. The cabability to display CTD data using the SCS system and monitors will be available. Survey technicians and scientists will keep the "CTD Cast Information/Rosette Log" in addition to the wire usage log. The CTD should descend at a rate of 30m/min for the first 200m and 45m/min below that. The ascent rate should be 50m/min. The FOCI fluorometer, light meter, and chlorophyll absorbance meter (ChlAM) should be mounted on the rosette for all casts where possible. However, the ChlAM can not exceed 300m and the fluorometer and light meter cannot exceed 500 m. Water samples will be collected with 10-l Niskin bottles. Depth, fluorescence and light levels will be recorded on the "CTD Cast Information/Rosette Log" for all water bottle samples.
2.3.1 CTD Calibration: Salinity comparisons will be conducted on every cast (or as specified by the Chief Scientist). No reversing thermometers will be required. The CTD systems will be equipped with dual thermistors. A survey technician will run the AutoSal analysis during the cruise and record the readings on an AutoSal log.
The purpose of the Vessel-Mounted Acoustic Doppler Current Profiler (VM-ADCP) is to measure the ocean current velocity continuously over the upper 300 m of the water column, usually in 8 m depth increments. Current velocities relative to the earth at this spatial and temporal resolution cannot be measured by other methods: CTD sections, current meter moorings, or drifting buoys.
ADCP data is also used to estimate the abundance and distribution of biological scatterers over the same depth range and in the same depth increments.
ADCP Data Collection:
ADCP measurement requires four instruments working in concert: the ADCP, the ship's gyrocompass, a GPS receiver, and a GPS Attitude Determination Unit (ADU). The ADCP is connected to a dedicated PC and controlled by RD Instruments' Data Acquisition System (DAS) software. Version 2.48 of DAS software will be used as the controlling software. The DAS software shall be configured to use the user-exit programs AGCAVE.COM and UE4.EXE.. Separate written instructions detailing the ADCP setup and configuration files are kept in the ADCP notebook in the DataPlot compartment.
The ADCP PC is interfaced to the ship's gyrocompass, to the primary scientific GPS receiver, and to the GPS Attitude Determination Unit. The navigation GPS shall be configured to send only NMEA-0183 messages $GPGGA and $GPVTG at the maximum fix update rate for the receiver (usually 1 or 2 second rate), and with the maximum number of digits of precision (optimally 4). The Ashtech 3DF Attitude Determination Unit shall be configured to send the $PASHR,ATT message at least once, preferably twice, per second, and the NMEA-0183 message $GPGGA once each second. The user-exit program UE4.EXE shall be configured to control acquisition and processing of GPS and ADU messages, and to synchronize the PC clock with the time reported by the primary GPS.
The ADCP PC logs data from the profiler to SyQuest disks and optionally sends a complete data structure to SCS for logging on that system. This redundancy in data logging is desirable for post-cruise processing flexibility. The user-exit progam UE4.EXE should be configured to send an "RDI-style" ensemble to SCS.
PMEL supplies the SyQuest disks for FOCI projects. No more than one SyQuest disk will be required for the cruise. At the end of the cruise, a backup of the SyQuest should be made to a unique subdirectory of another disk maintained by the ship for this purpose until the original data is certified at PMEL.
Detailed, post-cruise processing of ADCP data is designed to take advantage of a higher quantity of navigation data than is retained by the ADCP acquisition software. Thus, the ship's SCS is relied on to log GPS navigation data at maximum available rates. The SCS system shall log output from the best two navigation receivers at all times during a cruise. For the purpose of designating a primary and secondary GPS system, precedence shall be assigned according to the following list of GPS receivers available on the Miller Freeman:
1. Trimble Centurion with encryption key installed and enabled (PPS-GPS)
2. Northstar 941X receiving differential corrections from radiobeacon (DGPS)
3. Trimble Centurion operating without encryption key (SPS-GPS)
4. Northstar 941X without differential corrections (SPS-GPS)
5. Magnavox MX-200 (SPS-GPS)
6. Ashtech 3DF ADU (SPS-GPS)
Changes in the availability of GPS equipment shall be communicated to PMEL to allow the above list to remain current. It is the responsibility of the ship to install and enable the appropriate encryption key for use of a PPS-GPS receiver.
The SCS file SENSOR.DAT should be configured to enable logging only of the NMEA-0183 format messages $GPGGA and $GPVTG from navigation sources; derived sensor messages are not desirable for post-cruise processing.
Similarly, only raw messages from the gyrocompass ($HEHDT) and GPS ADU ($PASHR,ATT) are desirable for logging.
SCS should log the primary GPS data at 1 second intervals, the secondary GPS data at 10 second intervals, gyro data at 10 second intervals, GPS ADU messages at 10 second intervals, and the temperature and input voltage of the ADCP electronics (deck unit) at 60 second intervals. The latter are used for adjusting the acoustic backscattered signal strength to absolute levels and relating the signal to biological scatterers.
ADCP Underway Operations:
The ADCP operates continuously during the entire cruise. At the start of a cruise, the system shall be configured and started according to the provided checklists "Before Leaving Port" and "Underway to Operations Area". The ADCP and its interface to the gyro and navigation must be checked daily by completing the "ADCP Daily Log" and also at the end of the cruise with the ship tied to the pier. The centerboard height affects the depth of sampling. The centerboard shall be lowered as soon as practical upon leaving port and remain lowered throughout the cruise. If it is necessary to raise the centerboard during the cruise, the times of raising and lowering must be logged in the Marine Operations Abstract (MOA).
In case of problems please describe the problem, error message numbers, flashing lights, etc. on the log sheets. Also contact Dan Dougherty (206-526-6844; e-mail DOUGHERTY@PMEL.NOAA.GOV) or Ned Cokelet (206-526-6820; e-mail COKELET@PMEL.NOAA.GOV) at PMEL as soon as possible.
Dedicated ADCP transects should be run at constant heading (not constant course-over-ground) if practicable, thus minimizing gyro lag. However, transects along lines of current-meter moorings should remain on the line with the ship's heading gradually adjusted to accomplish this. Sharp turns should be avoided. The ship's speed should be constant. 12 kts is often satisfactory, but the ship may have to slow down if the ADCP's percent good pings decreases below 75% in the upper 200-250 m due to sea state.
The ADCP should operate in bottom track mode when the water depth is less than about 500 m for more than a few hours. This gives currents better-compensated for transducer misalignment but somewhat lower in statistical significance because the number of pings is reduced. For extended periods in deeper water, an ADCP configuration without bottom tracking should be used.
ADCP Backtrack-L Calibration:
At least one backtrack-L calibration maneuver per cruise should be executed to test the instruments and to calibrate the transducer misalignment angle for which a 0.5Ä error can seriously bias the measurements. The "misalignment angle" may change with the ship's trim as well as with remounting the ADCP transducers. The basic idea is to measure the current twice on closely spaced parallel tracks of opposite heading when the ADCP and GPS are working well. The maneuver consists of 4 legs (N, S, E and W headings) connected by simple U-turns forming an L shape. Each leg should be 30 minutes long - the first 10 minutes are to allow the ship and instruments to stabilize on the new heading. The entire calibration should require about 2 1/2 hours with 5 minutes allowed for each turn. The following should be considered:
- Negligible currents are best, but stronger currents are acceptable as long as they are reasonably uniform and steady. Avoid regions of strong horizontal shear due to topography, flow through passes, eddies and current boundaries. In tidal currents measure when the current is steadiest, often at maximum flood and ebb rather than at slack water.
- Calibration legs can be done in any order provided opposite-headed legs are sequential.
- Opposite-headed legs should be parallel and closely spaced, but not retraced. Use U-turns to minimize gyro oscillations. Avoid Williamson and hairpin turns.
- The ADCP's PC screen should show at least 75%-good pings down to 250 m.
- The ship should go fast enough to detect a misalignment error (over 5 kts), but slow enough to satisfy condition 4. This depends on sea conditions. 10-12 kts is often satisfactory.
- Choose a time when GPS is navigating and is expected to remain so over the next 2 hours.
ADCP Absolute Backscatter Calibration:
A test to calibrate the absolute backscatter strength and to determine the background noise level of the ship-ADCP system may be performed once per cruise at the discretion of the Chief Scientist. Specific instructions in such event will be provided by PMEL personnel aboard, and cannot be anticipated in advance of the cruise.
Typically, such a test will be attempted in conditions when weather is relatively calm, and the water depth exceeds 250 m. This test may require that the main power plant, pumps, sonars, and other sources of acoustic and electronic noise be shut down. If conducted in the course of normal operations, the work will require about 1 hour. There may be opportunities for variations of the test any time the ship is at anchor, requiring the cooperation of the ship's officers and engineering watch.
The ship will be equipped with a radiometer to measure solar energy. The scientists will supply the calibrated instrument, mounting hardware and cable to run to DataPlot. We will need the assistance of the ship's electronics tech and SCS Manager to correctly install the instrument and make sure that the data are being logged by the SCS.
The ship will be equipped with a thermosalinograph. The pump for the thermosalingraph should run continuously. Approximately every two months, the ship is required to open the compartment to the thermosalinograph and clean the thermosalinograph intake.
3.0. FACILITIES AND EQUIPMENT
3.1 Equipment and Capabilities to be Provided by the Ship
The following systems and their associated support services are essential to the cruise. Sufficient consumables, back-up units, and on-site spares and technical support must be in place to assure that operational interruptions are minimal. All measurement instruments are expected to have current calibrations, and all pertinent calibration information shall be included in the data package.
3.2 Equipment to be Provided by the Project:

3.3 Ultra-cold Freezer Requirements
- Sea-Bird SBE-19 Seacat ,SBE 36 deck unit, SBE Power Data Interface Module (PDIM), and a SBE 5T pump (primary).
- Miscellaneous scientific sampling and processing equipment
- Scientific ultra-cold freezer
- Subsurface moorings (2)
- Trawl Resistant ADCP Platforms (2)
The scientific ultra-cold freezer will remain on the ship in operating condition from the beginning of the first FOCI cruise until the ship returns to Seattle and the samples within can be unloaded. Since valuable samples will be in the unit, operation must be continuous without interruption. Therefore, the unit should be hardwired into the ships electrical system or connected with a threaded plug. The unit must be securely fastened to a bulkhead or counter, easily accessible, with a minimum of 4" on each side around the bottom. The location, fastening and wiring should be similar to last year. In addition, a weight should be taped to the top of the unit to prevent the lid from lifting in heavy seas.
The freezer has an alarm, but the ship's personnel are requested to check the digital temperature display twice daily to insure that the operating temperature is below -60 degrees C. The unit will be locked between cruises, and a key left with the Chief Survey Tech. In the event that the unit fails, the temperature will maintain for about 12 hours if the lid isn't opened. If the unit fails and cannot be fixed on the ship, the scientific blast freezer should be pre-cooled to its minimum (-38 degrees C), and all frozen specimens should be transferred to it immediately, without thawing. Kevin Bailey (206/526-4243, 4239) must be notified.
A daily record of the temperature (digital readout) on the scientific ultra-cold freezer will be submitted to K. Bailey (AFSC) upon the ship's return to Seattle.
3.4. Scientific Computer System (SCS)
The ship's Scientific Computer System (SCS) shall operate throughout the cruise, acquiring and logging data from navigation, meteorological, oceanographic, and fisheries sensors.
The SCS data acquisition node will provide project scientists with the capability of monitoring sensor acquisition via text and graphic displays. A data processing node will be available to project scientists throughout the cruise, configured according to the specifications of the FOCI SCS administrators.
Sensor identification, and data acquisition and logging parameters are specified in the system file SENSOR.DAT. This file shall be maintained in a current state by the ship's SCS manager. Specific FOCI requirements for the content of the SENSOR.DAT file shall be provided by the FOCI SCS administrators prior to the start of the 1996 field operations season. Changes to the SENSOR.DAT specifications may be made by the ship's SCS manager on a cruise-by-cruise basis, at the request of the chief scientist. All changes in content of the SENSOR.DAT file shall be communicated to the FOCI SCS administrators.
SCS sensor data logged to disk files shall be organized into several logical groupings according to intended post-cruise processing. These logical groupings will be specified by the FOCI SCS administrators prior to the start of the 1996 field operations season. The ship's SCS manager will assign data elements from newly-installed sensors to the appropriate logical group(s), and inform the FOCI SCS administrators of such changes.
At regular intervals, not to exceed every 5 days, SCS ship's manager will archive data from disk files to 8-mm tape cartridge for delivery to the project representative at the end of the cruise. To ensure compatibility with the laboratory tape drive mechanisms, backup 8-mm tapes shall not be recorded with hardware compression options.
Real-time data will also be logged to QIC tapes to provide additional data security in the event of disk failure; these tapes will be archived by the ship until project data tapes have been received and verified by the laboratories.
The ship's SCS manager will ensure data quality through the administration of standard SCS protocols for data monitoring. If requested by the chief scientist, standard SCS daily quality assurance summaries will be prepared for review.
Additional recording of processed data may be requested of the ship's SCS manager; if so, specific instructions will be found elsewhere in this document. During the cruise, the scientific party may require the assistance of the ship's SCS manager to determine if all sensors are functioning properly and to monitor some of the collected data in real time to make sampling strategy decisions.
