m off bottom.
2.3 Equipment Loading
All mooring equipment and instrumentation will be shipped to Dutch Harbor
prior to the beginning of the Tsunami cruise by Western Pioneer. 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 21 May 1997. 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 (Attachments 3 and 4), consists of an expendable steel plate anchor
attached to a combination aluminum tripod and platform. Mounted on the
platform are one acoustic release and the BPR pressure case. 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 ceterboard. The acoustic release will then
be interrogated and the anchor released, allowing the BPR to float to the
surface. During the interrogation of the mooring and during the mooring's
ascent, the ship should remain DIW with the screws secured while the transducer
is over the side so that the unit can be tracked using ranging information.
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 enable recoveries and deployments at night,
if necessary. 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. A transducer is lowered over the side as before and ranging information
is used to track its 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 SUMMARY OF FOCI CTD BONGO ACTIVITIES:
CTD/rosette and bongo samples are requested from six of the seven time
series stations (Line 8 FOX 056 - FOX 061). At each station a CTD cast
to within 10 m of the bottom will be done. On the upcast, water samples
for nutrients, microzooplankton, and chlorophyll will be taken using 10
l Niskin bottles. Bongo operations (off the starboard quarterdeck) will
simultaneously use the 20 and 60 cm diameter frames (150 and 333 mm mesh
nets, respectively) and the SeaCat to determine maximum tow depth. Tows
are to 10 m off bottom; only one side of each frame is to be preserved
in formalin. The other side can be discarded.
2.7 PROCEDURES FOR OPERATIONS:
The following FOCI operations are to be conducted on this cruise. The
proceures are listed in the FOCI Standing Operating Instructions (SOI)
for NOAA Ship Miller Freeman and reflect anticipated sampling plans as
of this date.
CTD (SOI 2.2.1)
MARMAP bongo tows (SOI 2.2.2)
Bongo larval conditon twos (SOI 2.2.3)
Chlorophyll Samples (2.2.10)
Satellite-tracked drifter buoys (SOI 2.2.11)
2.8 MARMAP Bongo Tows
A 20 cm bongo with 0.150 mm nets and a 60-cm bongo net with 0.333 mm
net, both with hard plastic codends and a 40 kg lead weight for a depressor
will be used in standard MARMAP tows. The 20 cm frame is attached to the
wire 1 m above the 60 cm frame. The nets will be deployed at a constant
wire speed of 40 m/min to a maximum depth of 10 m off bottom. A CTD (Seacat)
or electronic BKG will be attached to the wire to provide real-time tow
data. The depth of the nets will be monitored from DataPlot and commands
given to stop the winch. The winch will be stopped and the nets allowed
to stabilize for up to 30 sec. The nets are then retrieved at a wire speed
of 20 m/min. The ship speed is adjusted to maintain a wire angle of 45
degrees during the entire tow. When the nets reach the surface they are
brought aboard and hosed to wash the sample into the codend. Only one side
of each net frame will be preserved (5% formalin). Flow meters in the nets
record the amount of water filtered and an electronic CTD or bathykymograph
records the depth history of the tow. The Scientists on watch are responsible
for recording times and maximum depth obtained in the Seacat logbook. Tows
not meeting specifications may be repeated at the discretion of the scientific
watch.
The PMEL SeaCat data will be acquired on a PMEL computer using SEASOFT
software.
2.6.4 Station Plot
It is requested that the position of each operation and station will
be maintained in a SeaPlot file. If possible a disketteof the file will
be given to the chief scientist.

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,

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 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.
