Final CRUISE INSTRUCTIONS
NOAA Ship MILLER FREEMAN
Cruise No: MF99-06
FOCI No: 3MF99
These instructions, with FOCI Standard Operating Instructions for NOAA Ship MILLER FREEMAN, 1999, present complete information for this cruise.
General geographic area:
Southeastern Bering Sea Shelf
Date depart/port: 1 May 1999; Dutch Harbor, AK (T/G)
NOAA - Alaska Fisheries Science Center (AFSC)
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 (SEBSCC). 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.
1.1. Chief Scientist:
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:
1.3 NOAA Pacific Marine Center Operations Contact:
1.4 Program Contacts:
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.2.1. SUMMARY OF ACTIVITIES:
After departure we will proceed to the stations surrounding Mooring 2 (Figure 1). CTD casts (nutrients and chlorophyll) and tows for zooplankton (bongo and CalVET) will be taken at the first five stations (Table 1). We will then spend approx. 20 hr. at M2 for rate measurements (CTD, bongo, CalVET, and 0.8 m Ring net) before steaming north along the 70 m isobath transect, stopping for CTD and bongo samples at designated stations. After completing stations on that transect, we will occupy station M4 for 20 hr to do rate measurements. Upon completion of those measurements we will steam southwest to sample selected stations between the Pribilof Islands, then dead head to the shelf break stations. The cross shelf transect will then be sampled, stopping at M3 for 20 hrs for more rate measurements. The cross shelf transect stations will then be resumed, concluding at M2 with 20 hrs of rate measurements. If time permits, we will take water and plankton samples at stations inshore of Mooring 2 and do a series of MOCNESS tows north of Unimak Island for larval fish before returning to Dutch Harbor.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.
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. In addition to the standard data products requested by FOCI, we request ASCII files of the one minute averaged thermosalinograph logical data group data (GMT, position, T, S, water depth, insolation, and underway fluorescence). Contact CST Wm. Floering for further information.
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:
None at this time.
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.
