These instructions, with "FOCI
Standard Operating Instructions for NOAA Ship MILLER FREEMAN, 1999"
present complete information for this cruise.
Area:
General geographic area: Southeast Bering Sea.
Itinerary:
10 April 1999: depart Kodiak, Alaska

CRUISE DESCRIPTION:
Fisheries Oceanography Coordinated Investigations (FOCI) is
an effort by NOAA scientists to understand the physical and biological
processes that determine recruitment variability of commercially valuable
finfish and shellfish stocks in Alaskan waters. At present, FOCI consists
of a Shelikof Strait walleye pollock project (western Gulf of Alaska),
and a NOAA Coastal Ocean Program (COP) project: Southeast Bering Sea Carrying
Capacity. The COP project is a collaborative effort by NOAA and academic
scientists to understand the affects of abiotic and biotic variability
on the SE Bering Sea ecosystem.
CRUISE OBJECTIVES:
1. Bongo tows and EK500 survey to locate area of pollock spawning/egg
concentration over southeast shelf (Kendall).
2. Biological oceanographic sampling (CTD, water bottle, Bongo, and
CalVET) at 13 stations at and around Mooring 2 , Mooring 3, and two stations
on middle and outer shelf domain (Napp).
3. Depth-stratified MOCNESS tows to determine pollock eggs vertical
distribution (Kendall).
4. Live Tucker trawls to obtain pollock eggs to return to Seattle for
specific gravity measurements (Kendall).
5. Trawl for spawning pollock.
A. Incubate eggs to bring to Seattle for rearing (Porter) and
specific gravity measurements (Kendall).
6. Live CalVET tows to obtain copepod eggs (Baier).

2.0. OPERATIONS
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:
Pollock egg vertical distribution: A bongo survey of 48 stations
will be conducted over the shelf of the southeastern Bering Sea to map
pollock egg distribution and locate areas of high concentrations. Within
the area of the survey, two locations will be selected for vertical distribution
tows with the MOCNESS. At each of these selected locations, first, two
MOCNESS tows with nets tripped at 15 to 20-m depth intervals, from surface
to bottom, will be performed and the samples preserved for analysis ashore.
Then live Tucker tows will be made near surface (0-20 m) and near bottom
(ca. 80-100 m) to obtain live eggs to return to Seattle for specific gravity
experiments.
Middle and Outer Shelf Domain monitoring observations: Biological oceanographic
observations will be taken at up to13 stations over the shelf in the southeast
Bering Sea.
Live Tucker trawl tows for pollock eggs: One or more Tucker trawl tows,
with one net fishing near bottom (80-100 m), and the other from that depth
to the surface will be conducted over the shelf in the Bering Sea to obtain
live pollock eggs to bring back to Seattle for experimental work at AFSC.
Taped codends will be used to minimize trauma to the eggs during collection.
At the conclusion of the tows, the nets will be gently washed and live
eggs will be sorted from them immediately. Those from the at-depth net
will be placed in rearing refrigerators. At the end of the cruise these
live eggs will be packed in insulated bottles for air transport to Seattle.
Pollock egg incubations: The ship will locate aggregations of walleye
pollock over the shelf of the southeastern Bering Sea, using information
from the fishing fleet. Ship and scientific personnel will monitor the
EQ-500 echosounder to identify these aggregations. When walleye pollock
are located, a midwater trawl will be deployed. Ripe walleye pollock caught
in the trawls will be stripped and the eggs will be maintained in the large
refrigerator located in the fish processing lab. Live eggs (~20,000)
will be brought back to Seattle for experimental work at AFSC. Once sufficient
eggs are obtained for the experiments, the ship will break off these operations.
2.2 PROCEDURES FOR OPERATIONS:
The following are operations to be conducted on this cruise.
The procedures for these operations are listed in the FOCI Standard Operating
Instructions (SOI). Operations not addressed in the SOI and changes to
standard procedures are addressed below.
CTD/Water samples (SOI 2.2.1)
MARMAP bongo tow (SOI 2.2.2): Both Line 8 and standard 60 cm bongo tows
will be taken. 0.333 and 0.505 mm mesh nets will be used for the standard
bongo tows.
Live Tucker trawl tows (SOI 2.2.3): Live tows will be taken for pollock
eggs using 0.505 mm mesh nets, and taped codends. Depths of tows may vary
from those in SOI. After gentle rinsing, both codends will be sorted for
pollock eggs immediately following retrieval.
MOCNESS (SOI 2.2.5): 0.505 mm mesh nets will be used. Sampling depth
intervals will be 0 20, 20-40, 40-60, 60-80, and 80-100 m, as water depth
permits. The gear may be deployed off the stern without the platform provided
care is used to minimize damage to the gear.
Live CalCOFI Vertical Egg Tow (SOI 2.2.6): Live tows will be taken for
collecting copepod eggs. The Chief Scientist or watch chief will decide
station locations.
Midwater trawl (SOI 2.2.8): Trawling for spawning adult pollock will
be conducted using whichever trawl is deemed most suitable. Midwater trawls
will be deployed using standard procedures for the gear requested. The
Chief Scientist or watch chief will decide trawl locations, times and depths.
Midwater trawls will be conducted day or night and will depend on plankton
catches or midwater sign seen on the EQ-50 echosounder. Once a trawl is
called for, regardless of the time of day, the fishing crew will need to
be activated quickly, with little time lost. Trawl time should be of short
duration; only long enough to descend into the school, fish for 10-15 minutes,
then be brought up. The trawl should be landed as quickly as possible and
emptied into the sorting table on deck. Scientific personnel will quickly
sort through the catch and put suitable fish into filled sinks in the wet
and/or fish processing labs. Should it be necessary to obtain more ripe
fish at the same location, the trawl should be readied and re-deployed
as quickly as possible.
Tucker trawl (SOI 2.2.9): 0.505 mm mesh nets will be used.
Chlorophyll samples (SOI 2.2.10)
EK500 monitoring (SOI 2.2.12)
