Cruise Description and Objectives:

The objectives of this cruise are: 1) To recover five and deploy four Bottom Pressure Recorders (BPR's) , and recover one tsunami real-time surface mooring in the North Pacific Ocean off of the Alaskan Peninsula in support of the Pacific Tsunami Observational Program (PacTOP). PacTOP is a research program designed to obtain quality tsunami data in order to resolve theoretical and modeling tsunami issues. The goal of PacTOP is to acquire high quality tsunami measurements during the generation and deep ocean propagation of one or more tsunami events. 2) In support of the Fisheries-Oceanography Coordinated Investigation (FOCI) program, Four Acoustic Doppler Current Profiler (ADCP) transects will be conducted, time and weather permitting. See Attachment 1 for BPR sites.

Scientific Measurements:

--Recover four BPR moorings and deploy four BPR moorings at each of the four recovery sites.
--Recover one tsunami real-time surface mooring and recover the BPR mooring at the same site.
--One CTD/Rosette cast to 500 meters at each BPR site.
--Four ADCP transects maintaining a speed of 10 knots.

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.

2.0 OPERATIONS

2.1 Loading

The following Mooring items will be loaded on the MILLER FREEMAN prior to departure from kodiak, AK on May 12, 1998.

2.2 Underway Operations

Upon completion of loading and preparations at Kodiak, the ship will proceed to the real time Tsunami surface mooring, RT01 (see Attachment 1). The surface mooring and accompanying BPR mooring will be recovered at this site. The ship will then proceed to BPR station #80 where a BPR mooring will be recovered and redeployed at the same site. At each BPR site, a 500-meter CTD cast will be taken if time and weather permits. Following which, BPR's will be recovered and redeployed at stations 79 and 78. After the deployment at station 78, the first ADCP transect will be run from the following points:

After completing the ADCP transect, the ship will proceed to BPR Station AK77 where the last BPR will be recovered and redeployed.

The coordinates of the five BPR Stations are as follows:

BPR

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.
All equipment and instrumentation will be off-loaded in Kodiak, AK at the end of the cruise, on or about 19 May 1998. The Equipment will then be barged from Kodiak, AK back to Seattle, WA.

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:

The following FOCI operations are to be conducted on this cruise on a not to interfere basis. The procedures are listed in the FOCI Standing Operating Instructions (SOI) for NOAA Ship Miller Freeman and reflect anticipated sampling plans as of this date.

4.0 DISPOSITION OF DATA AND REPORTS

4.1 Data Responsibilities

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:
Marine Operations Abstracts,
Marine weather observation logs,
PMEL CTD weather observation logs,
CTD audio cassettes,
CTD Cast Information/Rosette Log,
Calibration sheets for all ship's instruments used,
Autosalinometer logs,
ADCP log sheets,
ADCP SyQuest 105 MB disks,
SCS 8 mm backup tapes,
SeaPlot Files, disk. NOS chart or overlay not required,
Ultra-cold freezer temperature daily log, (end of field season).

4.2.1. Marine Observation Log:

A Marine Operations Abstract (MOA) form will be maintained by the ship's officers during the cruise. The critical information to record at each station is:
GMT date,
GMT time,
position,
station #,
haul #,
gear type
bottom depth.
At present, a paper form (hard copy) MOA is the most secure method for ensuring that these data are recorded and preserved. However, the Program is willing to work with PMC to develop an electronic version that is efficient, secure and could eventually replace the paper MOA.

4.3 Cruise Report

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

Any additional work will be subordinate to the main project and will be accomplished with concurrence of the Chief Scientist and on a not-to-interfere basis.

5.1 ADCP Piggyback Project

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.

5.2 Ancillary Tasks

Will be accomplished in accordance with the NOAA Fleet Standing Ancillary Instructions.

6.0 MISCELLANEOUS
