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.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.

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.

A standard oceanographic watch will be utilized which consists of a winch operator, a scientific staff of two, and a Survey Tech. Operations will be conducted 24 hours per day.
2.1 SUMMARY OF ACTIVITIES:
The order of operations is highly dependent on ice/weather conditions at the time of the cruise.If weather and ice conditions are favorable, the following plan will be implemented.
Depart Dutch Harbor for site 2.There will be recovery of three moorings (F-00BS-2C, F-00BSP-2F and F-00BSST-2F) and deployment of three moorings (F-01BS-2B, F-01BSP-2S and F-01BSST-2S). In conjunction with the mooring operations, a grid of five stations at and surrounding the mooring will be sampled. CTD casts (nutrients and plankton) will be conducted at each of the five grid stations.
Next, four CTD casts (nutrients and plankton) between sites 2 and 3 will be completed.
At site 3, there will be recovery of one mooring (F-00BSP-3F). In conjunction with the mooring operations, a grid of five stations at and surrounding the mooring will be sampled. CTD casts (nutrients) will be conducted at each of the five grid stations.
Proceed to the 500-meter station (depth dependent) west of site 3 and begin L-shaped line of twelve CTD stations. At site 6, there will be recovery of one mooring (F-00BS-6).
During the cruise, isotopic and alkenone sampling will occur.This will consist of filtering approximately 50 liters of seawater using the thermosalinograph seawater intake line.In-line filter holders with a diameter of 47 mm will be used.The alkenone filters should be stored in a freezer at a minimum of -20°C.The filters will require minimal freezer space.
If time and weather permit, the clamshell grab may be used.
Nutrient sample depths - as possible - are surface, 10, 20, 30, 50, 75, 100, 150, 200, 250, 300 and near bottom).
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)
ADCP (SOI 2.2.13)
Radiometer (SOI 2.2.14)
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.
