DRAFT CRUISE INSTRUCTIONS

CCGS Sir Wilfrid Laurier
Cruise No: LA-98-00

Area:

Bering Sea, Gulf of Alaska

Itinerary:

Dates are approximate

July 10,1998: Kodiak, Alaska

July 15, 1998: Nome, Alaska

Participating organizations:

NOAA - Pacific Marine Environmental Laboratory (PMEL)

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:

1. Deploy mooring F-BSM98-2A

2.0. OPERATIONS

2.1. SUMMARY OF ACTIVITIES:

The PMEL operations during the Laurier cruise will consist of one mooring deployment and a CTD mooring calibration cast.

Mooring Operations: (see Appendices)

Site #2- Deploy one surface mooring (56· 52.5' N/ 164·03.0' W )

2.2 PROCEDURES FOR OPERATIONS:

The following are operations to be conducted on this cruise.

Mooring calibration CTDs will be completed after the mooring deployment.

Details and times of these operations are specified in the Appendices.

Mooring equipment and associated hardware will be loaded aboard the Laurier in Kodiak on or about July 10 1998. The PMEL mooring operations will begin in the Bering Sea at FOCI mooring Site #2 with the deployment of surface mooring F-BSM-98-2A in 72 meters of water. The PMEL work will be completed with a CTD cast for mooring calibration.

Mooring diagrams will be provided to ship by chief scientist before cruise .

3.0. FACILITIES AND EQUIPMENT

The following systems and their associated support services are essential to the cruise. Sufficient consumable, 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.
