FINAL CRUISE INSTRUCTIONS
NOAA Ship: MILLER FREEMAN


Cruise No: MF97-05, Leg I

Area: Southeast Bering Sea

Itinerary:
Depart April 15 -- Dutch Harbor
Return May 1 -- Dutch Harbor

Participating organizations:
NOAA - Alaska Fisheries Science Center (AFSC)
NOAA - Pacific Marine Environmental Laboratory (PMEL)
UAF - University of Alaska, Fairbanks


CRUISE DESCRIPTION:

Fisheries Oceanography Coordinated Investigations (FOCI) is an effort by academic and federal scientists to understand ecosystems and biological and physical processes that cause recruitment variability of commercially valuable fish and shellfish stocks in Alaskan waters. FOCI comprises Shelikof Strait FOCI, Bering Sea FOCI, and Southeast Bering Sea Carrying Capacity (SEBSCC). Presently research is focused on the western Gulf of Alaska and the southeastern Bering Sea to examine the affects of the biotic and abiotic environment on the ecosystem and the early life stages of walleye pollock. FOCI uses four scientific approaches: environmental monitoring, process studies, retrospective analyses, and modeling. Research cruises address the first two approaches.

CRUISE OBJECTIVES:
Recover and redeploy moorings (including sediment traps),
Recover lost instruments (TRAPS; Trawl Resistant ADCP PlatformS),
Occupy ecosystem monitoring stations,
Continue sampling shipboard time series of larval pollock development as a
function of temperature,
Obtain ADCP and ChlAM ground truth samples at moorings,
Determine if euphausiid net avoidance is affected by a lighted sampler,
Estimate copepod fecundity.

2.0. OPERATIONS


Scheduling of individual activities will depend upon weather conditions and progress of scientific work, therefore, firm advance scheduling of events will not be possible, and a continual dialogue between scientific and ship's personnel will be especially important. A contract has been awarded by PMEL to commercial divers for recovery of two, lost TRAPS at Mooring 2. The order of cruise activities (below) will be dictated by weather and the ability of the commercial divers to rendezvous with the Freeman and perform the recovery. The Chief Scientist and PMEL Mooring Specialists will meet with the Commanding Officer and Field Operations Officer the day before departure to determine the initial activities. To insure fulfillment of all the scientific objectives, the ship is asked to steam at maximum cruising speed whenever time in transit and between stations is greater than one hour.

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.

 

SUMMARY OF ACTIVITIES (See Table 1 and Figure 1):

The summary below is the tentative order of execution. The order of activities will be determined by the Chief Scientist in consultation with ship's personnel after PMEL has determined when they want to rendezvous with their diving contractor.

1. North Aleutian Slope Flow Transect -- We intend to occupy 6 CTD stations along this transect and recover/redeploy Mooring 6 and recover Mooring 7. Nutrient and chlorophyll samples and (20/60 cm) bongo tows will be taken at selected stations. The depths of the CTD casts are likely to exceed the maximum depths of the fluorometer and chlorophyll absorbance meter (ChlAM).

2. Basin/Shelf Break Transect -- We intend to occupy 7 CTD stations along this transect. Nutrient and chlorophyll samples and (20/60 cm) bongo tows will be taken at selected stations at the shelf break. The depths of some of the CTD casts are likely to exceed the maximum depths of the fluorometer and chlorophyll absorbance meter.

3. Cross-Shelf Transect -- We intend to occupy 18 CTD stations along this transect. Nutrient and chlorophyll samples and (20/60 cm) bongo tows will be taken at selected stations. Multiple bongo tows and CTD casts will be necessary at Moorings 2 and 3. The transect will be interrupted to complete operations at Moorings 2 and 3.

4. Mooring 3. Mooring 3 will be recovered and redeployed with a surface toroid buoy and meteorological instrument tower. Sediment traps will be deployed on a separate mooring within 0.1 nm of the main mooring. Multiple CTD casts (for nutrients and chlorophyll) will be required before recovery and after deployment. Between recovery and redeployment MOCNESS, Tucker, Methot, and bongo tows will be done in the vicinity of the mooring. After operations are completed we will continue the cross-shelf transect until we arrive at Mooring 2

5. Mooring 2. As the Miller Freeman proceeds to mooring site, the weather forecast will be monitored to determine if conditions are favorable to perform diving operations. If so, then the S/V Redeemer will be contacted to rendezvous with the Miller Freeman the next day. In the interim, Mooring 2 will be recovered and redeployed with a surface toroid buoy and meteorological instrument tower. Sediment traps will be deployed on a separate mooring within 0.1 nm of the main mooring. Multiple CTD casts (for nutrients and chlorophyll) will be required before recovery and after deployment. Between recovery and redeployment MOCNESS, Tucker, Methot, and bongo tows will be done in the vicinity of the mooring.
In preparation for the arrival of the diving vessel the Freeman will deploy marker buoys (3 anchors, ca. 600 lb., each) as close as possible to the TRAP moorings F-96BST-2S and F-96BST-2F. We may also need to deploy anchor buoys (2 - 4 anchors, 5000 lb., each) for the S/V Redeemer to tie up to during the dive operations. Two members of the scientific party will need to be transferred to the S/V Redeemer via Munson or RHIB when it arrives at the dive site. It may be necessary for the Freeman to work in the vicinity of the contractor's vessel during TRAP recovery operations (approx. 2 days). After operations are completed we will finish the cross-shelf transect stations before beginning the next transect.

6. Seventy Meter Isobath Transect -- We intend to occupy 7 CTD stations along this transect. Multiple bongo tows and CTD casts (for nutrients and chlorophyll) will be necessary at Mooring 4.

7. Deadhead either to Mooring 2 to complete gear comparison tests or to Unimak Pass.

8. Unimak Pass Box. A "box" transect of 18 CTD stations will be accomplished. Nutrient and chlorophyll samples and (20/60 cm) bongo tows will be taken at selected stations.

Miscellaneous Operations -- A 0.8 m ring net tow for live plankton will be performed most mornings before sunrise, regardless of geographic position. We will try to schedule these to co-occur with other station work.
