22 April, 1998
NOAA, Pacific Marine Environmental Laboratory (PMEL)
1.1 Chief Scientist:
LT Carrie Hadden NOAA Corps PMEL
The Chief Scientist has the authority to revise or alter the scientific portion of these instructions with the concurrence of the Commanding Officer, provided 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, or (4) alter the general intent of the instructions.
1.2 Participating Scientist:
1.3 Medical History
Before sailing, all scientific personnel will complete a NOAA Health Services Questionnaire(NHSQ), which will be given to the Commanding Officer at the beginning of the cruise. Clearances are valid for 2 years for scientists under age 50 and 1 year for age 50 and over.
The following Mooring items will be loaded on the MILLER FREEMAN prior to departure from kodiak, AK on May 12, 1998.
The coordinates of the five BPR Stations are as follows:
Following BPR site AK77, three additional ADCP transect lines will be
run (time permitting). The coordinates and speed are as follows:
2.3 Equipment Loading
All mooring equipment and instrumentation will be shipped to Kodiak,
Ak. or prior to the beginning of the Tsunami cruise by Linden. The equipment
is scheduled to be delivered to Jim Ackerlund (Dock Manager), by Wed, the
5th of May. Arrangements for storage of the equipment will be made in advance.
The ship's force can load the equipment at their convenience.
2.4 BPR Mooring Descriptions
The Tsunami Bottom Pressure Recorder (BPR) mooring configuration, Model 635-7H (Attachment 3), consists of an expendable steel plate anchor attached to a combination aluminum tripod and platform. Mounted on the platform are one acoustic release,the BPR pressure case and an MTR. Flotation is provided by seven Benthos glass spheres with yellow propylene hardhats fastened to a seven pack holder. A marker float with orange signal flag, transmitter, and strobe light are attached to aid in locating and recovering the units when they are at the surface.
2.5 BPR Recovery/Deployment Procedures
The EG&G Ocean Products Model 8011 deck unit will be used for both the
recovery and deployment operations. During recovery operations the ship
will heave to and attempt recovery by use of the transducer recently installed
and located on the ship. The acoustic release will then be interrogated
and the anchor released, allowing the BPR to float to the surface (which
takes between 30-60 minutes). Once the unit is on the surface it can be
recovered using a grappling hook or a small boat, if weather permits. The
line and BPR are then recovered using the port side J-frame. The mooring
recovery floats are equipped with a strobe and a transmitter to assist in
locating the mooring when on the surface. The ship's bridge will monitor
Ch. 70, or 156.525 MHz to facilitate nighttime recoveries.
A similar method is used for monitoring the BPR's descent after being deployed. The ship's thru-hull transducer is used to provide ranging information and track the moorings descent. The ship should remain DIW with the screws secured until the unit's position on the bottom is verified. When the instrument is determined to be on the bottom, a code is sent to disable the release.
2.6 PROCEDURES FOR OPERATIONS:
CTD's at all BPR sites (SOI 2.2.1)
Four ADCP transects (SOI 2.2.13)
2.6.1 Station Plot
3.1 Equipment and Supplies Provided by the Ship
The following systems and their support services are essential to the
project. Sufficient consumables, back-up units, and on-site spares and technical
support must be in place to assure efficient operations. All instruments
used for scientific measurements are expected to have current calibrations,
and all pertinent calibration information shall be included in the data
3.2 Equipment and Supplies to be provided by the Scientific Party
(a) EG&G deck unit (Model 8011) and transducer (Model 8012)
4.0 DISPOSITION OF DATA AND REPORTS
The Chief Scientist is responsible for the disposition, feedback on data quality, and archiving of data collected on board the ship for the primary project. As the representative of the program manager (the Director, PMEL), the Chief Scientist is also responsible for the dissemination of copies of these data to participants in the cruise, to any other requesters, and to NESDIS in accordance with NDM 16-11 (ROSCOP) within 3 months of cruise completion. The ship may assist in copying data and reports insofar as facilities allow.
The Chief Scientist will receive all original data gathered by the ship for the primary project, and this data transfer will be documented on NOAA Form 61-29 "Letter Transmitting Data". The Chief Scientist in turn will furnish the ship with a complete inventory listing all the data gathered by the scientific party, detailing types and quality of data. The Commanding Officer is responsible for all data collected for ancillary projects until those data have been transferred to the projects' principal investigators or their designees. Data transfers will be documented on NOAA Form 61-29. Copies of ancillary project data will be provided to the chief scientist when requested. Reporting and sending copies of ancillary project data to NESDIS (ROSCOP) is the responsibility of the program office sponsoring those projects.
4.2 Data Requirements
The following data products will be included in the cruise data package:
4.2.1. Marine Observation Log:
A Cruise report to the Pacific Marine Center is no longer required. The Chief Scientist will furnish a cruise a report to the the tsunami program.
5.0 ADDITIONAL INVESTIGATIONS AND PROJECTS
The Fisheries-Oceanography Coordinated Investigation (FOCI) will conduct four Acoustic Doppler Current Profiler transects as outlined in Section 2.2 Underway Operations. The FOCI operation's work will require the ship to maintain a speed of 10 knots (12 knots may be achieved weather permitting) during each transect. The ship is to maintain course; however, adjustments for set and drift may be necessary. The bottom track mode must be secured.
6.2 Radio Interference
Some scientific equipment is sensitive to radio frequency interference. If interference occurs, it may be necessary to adjust operations and communications schedules if efforts to electronically isolate the equipment are unsuccessful.
INMARSAT will be available to the Chief Scientist for communication with
the laboratory. Requests for the use of INMARSAT will be approved by the
Commanding Officer. All communications costs ($6.02 per minute) will be
charged to the laboratory.
6.4 Planning Meeting
A precruise meeting between the Commanding Officer and Chief Scientist will be held prior to the start of the cruise. Its purpose is to identify the day to day requirements of the project in order to best utilize shipboard personnel resources and to identify overtime requirements. A brief meeting of all scientific personnel, the Field Operations Officer, Chief Boatswain, survey department, and other relevant ship's personnel should be held before the vessel reaches the experiment area in order to: 1) introduce new scientific personnel to ship's procedures, proper channels, etc.; 2) discuss operating procedures for deploying various pieces of sampling equipment; and 3) coordinate scientific watch assignments.
Following the cruise a post cruise debriefing will be held between the Chief Scientist and the Commanding Officer. If serious problems are identified, the Commanding Officer shall notify the marine center by the most direct means available. The chief scientist shall document identified problems in the Ship Operations Evaluation Form which will be submitted to the dirictor of PMEL within 30 days.
6.5 Navigational Control
Primary navigational control during the project will be GPS, visual, radar, etc.
