NOAA Ship MILLER FREEMAN
FOCI No: 1MF01
December 20, 2000
Applicability:These instructions, with FOCI Standard Operating Instructions for NOAA Ship MILLER
FREEMAN dated December 11, 2000 present complete information for this cruise.
Area:Northern Gulf of Alaska
Itinerary:Depart Kodiak, AK 1200 January 28, 2001 TNG
Arrive Dutch Harbor, AK 1200 February 5, 2001 TNG
Participating organizations:NOAA - Alaska Fisheries Science Center (AFSC)
NOAA - Pacific Marine Environmental Laboratory (PMEL)
CRUISE OBJECTIVES:We will be conducting bottom trawl sampling on the outer continental shelf and upper slope in the Gulf of Alaska beginning near Kodiak Island and ending near Sanak Island to collect ripe adult arrowtooth flounder (ATF). We will also be deploying deep bongo plankton tows to collect their eggs. This work is needed to establish the appearance of arrowtooth flounder eggs in the plankton, so they can be identified with confidence in samples. Data on physical characteristics of water in the area will also be collected.

2.1. SUMMARY OF ACTIVITIES:
Ship will proceed to the vicinity of line A, station 1 (appendices 1 and 2), and locate trawlable bottom at a depth of 200 m to deploy the first bongo tow and bottom trawl. This sampling will be repeated at two stations along a line moving offshore at depths of 400 and 600 m. Five additional lines (B-F) consisting of three stations of 200, 400, and 600 m depth are planned to be occupied during the survey. Whenever ATF eggs or ripe adults are found, a CTD cast with bottles will be deployed to collect data on the physical properties of water at the bottom and water for holding live eggs. We will then attempt to fertilize eggs from gravid females with sperm from ripe males aboard ship. Live eggs will be held in gallon jars placed in a constant temperature referigerator at 3-4ø C until the end of the cruise. If ripe female and male ATF are not collected, a sample of up to 50 adult ATF will be lengthed and dissected to determine sex and estimate maturity state. Bottom trawl and bongo sampling will continue until time allotted for the survey expires regardless of whether or not ripe adult ATF or suspected ATF eggs are found. A representative of the RACE Division, Alaska Fisheries Science Center, in Seattle, WA will contact the Miller Freeman by Inmarsat if ripe adult ATF are encountered in the Alaska commercial fishery and reported by the Observer Program. In this event, operations will be moved to the locality reported, if within the time constraints of the cruise.
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
SOI. Operations not addressed in the SOI and changes to standard procedures
are addressed below.
3.1 Equipment and Capabilities to be Provided by the Ship:
Oceanographic winch with slip rings and 3-conductor cable terminated for CTD,
Sea-Bird 911 plus CTD system3.3. Ship's 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. See FOCI Standard
Operating Instructions for specific requirements.
At the beginning of the cruise, an oceanographic
mooring located in Chiniak Bay will be retreived and necessary instruments
serviced or replaced, and then redeployed for the Kodiak NMFS Laboratory.
When time allows, fin clips and or/tissue samples will be collected from
sculpins (family Cottidae) and frozen or preserved in preserved in 95%
ethanol for a study of the molecular phylogeny of this family of fishes.
Carcasses of the sampled fish will be labeled and frozen or preserved in
10% formalin. This sampling is being conducted for Dr. Fumihito Muto, Laboratory
of Marine Biodiversity, Hokkaido University, Hakodate, Japan. In addition,
we will be collecting data from Pacific ocean perch (Sebastes alutus),
dusky rockfish (S. ciliatus) and northern rockfish (S. polyspinus) for
an age at maturity study in the Gulf of Alaska. Fish will be selected from
each haul using stratified random sampling based on two individuals per
1 cm length interval for each sex of each species. Fork length, somatic
weight, gonad weight and macro-maturity stage will be recorded for each
fish. Otoliths and gonads will be collected from these fish. The gonad
samples will be preserved in 10% neutral buffered formalin. Digital photos
of gonads may be taken of certain maturity stages for future comparison
with microscopically determined maturity stages of the gonads. This sampling
is being conducted for Ms. Elizabeth Chilton, Alaska Fisheries Science
Center, Kodiak Laboratory.
The Chief Scientist shall be responsible for complying with NC Instruction 6280A, Hazardous Waste; policy, guidance, and training, dated February 4, 1991, paragraph 7.g and paragraph 9. By federal law, the ship may not sail without a complete inventory of MSDS, and appropriate neutralizing agents, buffers, and/or absorbents in amounts adequate to address spills of a size equal to the amount aboard.
The following hazardous materials will be provided and controlled by the scientists with the Chief Scientist assuming responsibility for the safe handling of such substances:
