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 is comprised
of Shelikof Strait FOCI and Southeast Bering Sea Carrying Capacity (SEBSCC).
Current 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:
1) Continue acquisition of long-term biological and physical time series.
2) Conduct acoustic and trawl survey of juvenile walleye pollock for
examining distributions in relation to hydrographic fronts.
3) Compare multiple frequency acoustic systems and their use in examining
zooplankton and juvenile pollock spatial patterns.
4) Collect samples of juvenile pollock for studies of growth, feeding,
pathology, and condition.
5) Examine distribution and nutrition of pollock prey in relation to
hydrographic fronts and vertical distribution of juvenile pollock.
6) Examine distribution and feeding of seabird and marine mammal predators
in the vicinity of the Pribilof Islands.

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. 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 at least three and a Survey Tech
on deck. Operations will be conducted 24 hours a day.
2.1. Summary of Activities
The summary below is the tentative order of execution, but this may
be changed by the Chief Scientist. Some gear, including the anchovy trawl
and doors, will be loaded onto the ship during September 1 or 2 prior to
the beginning of the cruise. On or about September 5, the Miller Freeman
must return to Dutch Harbor to pick up the remaining scientists and Ken
coyle’s HTI towed-fin acoustic system. Most of the gear will be left
aboard until the ship can be off-loaded in Seattle.
1) September 2-5, SEBSCC Monitoring:
Proceed to the southwesternmost SEBSCC Monitoring station, there are
30 SEBSCC Monitoring stations (Table 1, Figure 1). Sampling at these stations
will include CTD casts for physical, chlorophyll and nutrient data; combined
20 & 60 cm bongo tows for zooplankton; and CalVET tows for microzooplankton.
This sampling will be suspended when need be to run to Dutch Harbor and
will be completed after the Juvenile Pollock Habitat work, time permitting.
2) September 5-19, Juvenile Pollock Habitat:
i) After the touch-and-go, proceed to the offshore end of Line D off
St. George Island (Fig. 2). Depending upon time of day, sampling will begin
either with acoustic transecting or CTD sampling. The schedule of events
listed in Table 1, after the Dutch Harbor TNG (5 Sept), will likely change
so that day or nighttime operations (see Operations, Table 1) will be conducted
during the appropriate diel period (see Day/Night, Table 1).
-Four acoustic passes will be made along this transect. One day and
one night pass will be conducted using the Simrad EK-500 system. Two more
passes will be made using Dr. Ken Coyle’s HTI towed-fin system. The
HTI fin will be towed from the starboard boom at a depth of ~3 m and ship
speed of 3-5 kts.
-One CTD cast will be made at each of the seven "D" stations.
Water bottles will be attached to the rosette for collecting nutrient,
chlorophyll and microzooplankton samples.
-Net sampling will be conducted using the MOCNESS, and the Methot and
anchovy trawls. Net sampling will occur at each of three stations selected
on the basis of thermal stratification: one inshore station (well mixed),
one middle station (partially stratified), and one outer station (stratified)
will be chosen. Two tows with each gear are planned at each of these three
stations. Again, net sampling is day/night sensitive so there will be considerable
adjustments made to the sequence of operations in Table 1. The HTI fin
will be towed off the starboard side during MOCNESS tows so that acoustic
and net sampling will be simultaneous.
-A 48-hr diel station may be scheduled at the middle station, but this
is not currently included in the current schedule (Table 1). The diel study
will be accomplished using the MOCNESS, and the Methot and anchovy trawl.
Each net will be fished once every six hours resulting in 8 samples per
gear per station.
-During the diel study, weather permitting, the rigid-hull inflatable
boat may be requested for collecting sea birds using firearms.
ii) Proceed to the inshore end of Line A off St. Paul Island (Fig. 2).
Depending upon time of day, sampling will begin either with acoustic transecting
or CTD sampling.
-Eight acoustic passes will be made along this transect. Four passes,
two at day and two at night, will be made using the Simrad EK-500 system.
Four more passes will be made using Dr. Ken Coyle’s HTI towed-fin
system.
-Initially, one CTD cast will be made at each of the ten "A"
stations. Water bottles will be attached to the rosette for collecting
nutrients, chlorophylls and microzooplankton samples. A second cast at
each station will occur nearer to the end of Line-A operations.
-A 48-hr diel study will be conducted at each of three select stations.
These stations will be selected on the basis of thermal stratification:
one inshore station (well mixed), one middle station (partially stratified),
and one outer station (stratified). As on Line D, net sampling will included
the MOCNESS, and the Methot and anchovy trawls. Again, each net will be
fished once every six hours resulting in 8 samples per gear per station.
The HTI fin will be towed off the starboard side during MOCNESS tows
so that acoustic and net sampling will be simultaneous.
-During each diel study, weather permitting, the rigid-hull inflatable
boat may be requested for collecting sea birds using firearms.
3)
A standard oceanographic watch will be utilized which consists of a
winch operator, a scientific staff of at least three and a Survey Technician
on deck. Operations will be conducted 24 hours a day. A fishing crew will
be required to assist with the MOCNESS, and the Methot, and anchovy trawls,
which may be conducted in daytime or nighttime. A Survey Technician and
winch operator will be needed for CTD operations. These will be conducted
at times to be determined by the Chief Scientist. The anchovy trawl catches
will be sorted and the taxa enumerated and weighed. Some of the juvenile
pollock will be preserved for growth, condition, and diet studies, the
rest of the catch will be discarded at sea. The MOCNESS and Methot catches
will be preserved entirely. All samples will be transported back to Seattle
aboard the Miller Freeman.
