Date: January 24, 2000 NOAA Ship MILLER FREEMAN Cruise No:MF00-01B
Applicability: These instructions, with FOCI Standard Operating Instructions for NOAA Ship MILLER FREEMAN dated June 25,1999 present complete information for this cruise. Area: Southeast Bering Sea, head of Bering Canyon Itinerary: Depart Dutch Harbor, AK
1200 February 15, 2000
Participating organizations: NOAA - Alaska Fisheries Science Center (AFSC) CRUISE DESCRIPTION: Fisheries-Oceanography Coordinated Investigations (FOCI) is an effort by NOAA and associated academic scientists. At present, FOCI consists of a Shelikof Strait (western Gulf of Alaska) walleye pollock project, and a NOAA Coastal Ocean Program project: Southeast Bering Sea Carrying Capacity. FOCI also supports associated projects, such as the Arctic Research Initiative, U.S. GLOBEC, and NSF Inner Front Study, that address scientific issues related to FOCI's. FOCI's goal is to understand the effects of abiotic and biotic variability on ecosystems of the North Pacific Ocean and Bering Sea in order to discern the physical and biological processes that determine recruitment variability of commercially valuable finfish and shellfish stocks in Alaskan waters. CRUISE OBJECTIVES: We will be conducting bottom trawl sampling in the head of Bering Canyon to collect ripe arrowtooth flounder (ATF) and deploying deep bongo plankton tows to collect their eggs. This work is needed to establish the appearance of arrowtooth flounder eggs, so they can be identified with confidence in plankton samples. Data on biological, chemical, and physical characteristics of water in the area will also be collected. 1.0. PERSONNEL 1.1. Chief Scientist: Busby, MorganM/USA
The Chief Scientist has the authority to revise or alter the technical portion of the instructions as work progresses provided that, after consultation with the Commanding Officer, it is ascertained 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; (4) alter the general intent of these project instructions. 1.2 Participating Scientists: Cartwright, RachaelF/USA;NOAA/AFSC

2.0. OPERATIONS A standard oceanographic watch will be utilized which consists of a winch operator, a scientific staff of three and a Survey Tech on deck. Operations will be conducted 24 hours a day. A fishing crew will be required to assist with bottom trawls which may be conducted in daytime or nighttime. They will be unscheduled because their occurrence depends on what is caught in plankton tows. 2.1. SUMMARY OF ACTIVITIES:
2.2 PROCEDURES FOR OPERATIONS:
Bottom trawl
A poly Nor'eastern or 83-112 bottom trawl will be used to collect live adult ATF to spawn on board ship to obtain live fertilized eggs. After deployment and settling of the net on bottom, it will be towed for 30 minutes at a speed of 1.5 m/sec. Location and duration of trawls, however, may be altered if bottom conditions will not allow a complete haul. ATF will be the only species processed from the catch. In the event of a large catch, only a subsample of ATF will be processed. Eggs will be stripped from gravid females and mixed with milt from ripe males and then counted and placed in thermoses and coolers for transport by air to Seattle. Niskin bottles will be deployed to collect water for holding and transporting eggs. Bongo tows using both 60 cm and 20 cm arrays will be conducted at each station. Bongo tows at stations 1 and 2 will be to 350 m depth. All others will be to within 10 m of the bottom. From each bongo tow, one sample will be examined at sea for the presence of possible ATF eggs and the other will be preserved and processed ashore. 3.0. FACILITIES AND EQUIPMENT The following systems and their associated support services are essential to the cruise. Sufficient consumables, back-up units, and on-site spares and technical support must be in place to assure that operational interruptions are minimal. All measurement instruments are expected to have current calibrations, and all pertinent calibration information shall be included in the data package. 3.1 Equipment and Capabilities to be Provided by the Ship Oceanographic winch with
slip rings and 3-conductor cable terminated for CTD,
3.2 Equipment to be Provided by the Project Sea-Bird SBE-19 Seacat system
(primary system),
3.3. 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.
4.0 DATA AND REPORTS Data disposition, responsibilities and data requirements are listed in the FOCI Standard Operating Instructions. 5.0 ADDITIONAL INVESTIGATIONS AND PROJECTS 5.3 Piggyback projects:
6.0 MISCELLANEOUS 6.5. Hazardous Materials: 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: Formaldehyde 7.0 COMMUNICATIONS 7.4 Important phone numbers, fax numbers and e-mail addresses: AFSC/RACE Fax: (206) 526-6723 MILLER FREEMAN COMSAT (government
