Cruise Objectives:
The purpose of this
cruise was to conduct a survey to locate the area(s) of pollock spawning
and high pollock egg concentrations over the southeast shelf of the Bering
Sea. Within areas of high egg concentrations, depth-stratified samples
were taken to investigate vertical distribution and specific gravity of
pollock eggs. In the Bering Sea, pollock eggs occur throughout the water
column, but mostly in the upper 40 m. This is different from the pollock
eggs in Shelikof Strait, Alaska, that are generally found at about 200
m. Samples collected during the cruise will be compared to similar previous
research on Shelikof Strait pollock eggs in order to find out why the eggs
are found at such different depths. In addition, a drifter was deployed
in a area of high pollock egg concentration to track the path over which
many of the eggs would be carried.
In areas where spawning pollock
were found, adults were collected by trawling, and live eggs were stripped,
fertilized, and transported back to Seattle, WA and Newport, OR. Larvae
reared from these eggs will be used for research on the swimming activity,
feeding and respiration, and behavior of pollock larvae, and for research
on the genetics of the pollock population on the eastern Bering Sea shelf.
Biological and physical oceanographic
samples were collected at 4 stations at and around Mooring 2 and Mooring
F99-BS-2A in order to continue long-term monitoring.
Onboard egg production experiments
for the copepod Calanus marshallae were conducted to determine reproductive
rates over the shelf at different temperatures. Calanus marshallae
are an important prey item for larval and juvenile pollock.
This cruise was conducted
for FOCI (Fisheries Oceanography Coordinated Investigations), a research
effort by NOAA scientists to understand the physical and biological processes
that determine recruitment variability of commercially valuable finfish
and shellfish stocks in Alaskan waters. At present, FOCI consists of a
Shelikof Strait walleye pollock project (western Gulf of Alaska), and a
NOAA Coastal Ocean Program (COP) project: Southeast Bering Sea Carrying
Capacity. The COP project is a collaborative effort by NOAA and academic
scientists to understand the affects of abiotic and biotic variability
on the SE Bering Sea ecosystem.
Summary of Operations (see
Table 1)
Physical oceanographic
measurements were made on conductivity-temperature-depth (CTD) casts. Water
samples were collected with bottles attached to the CTD profiler rosette.
Zooplankton, larval fish, and fish eggs were collected using bongo, ring
net, CalVET, Tucker, and MOCNESS (Multiple Opening Closing Net and Environmental
Sampling System) gear. An Aleutian wing trawl was used to collect adult
pollock.
Water samples were collected
from 4 stations at and around Moorings 2 and F99-BS-2A. Nutrient (27) and
filtered chlorophyll (30) samples from these collections were frozen for
later analysis. Fluorescence, ChlAM (chlorophyll light absorbance meter),
and PAR (photosynthetically active radiation) data were recorded during
all CTD casts (6).
Ichthyo- and zooplankton
samples were collected from tows using 60 cm bongo nets (42) and 20 cm
bongo nets (22). These samples were preserved for later analysis. Live
fish eggs were collected from the plankton using the Tucker trawl.(6).
All of these tows were made using the Seacat CTD. Additional tows were
made with the CalVET (California Vertical Egg Tow) for preserved micro-zooplankton
samples (3), and a ring net to collect live copepods (10). The MOCNESS
was used to collect depth-stratified ichthyoplankton samples (6), specifically
pollock eggs.
An Aleutian wing trawl (1)
was used to collect adult pollock. Eggs and sperm from ripe adults were
stripped and the fertilized eggs were incubated onboard for the last 18
hours of the cruise prior to being transported to Seattle, WA and Newport,
OR.
Two satellite-tracked buoys
were deployed during this cruise.
Summary of Cruise
Scientific personnel
boarded the ship in Kodiak. After a 50-hr steam to the Bering Sea, a satellite
tracked buoy was deployed at station 1 (Fig.1) over the 100m isobath. The
bongo survey began at station 2. After station 11, the ship left the grid
in order to conduct sampling around Moorings 2 and F99-BS-2A. Although
the CTD bottle firing mechanism malfunctioned on the first mooring station,
the problem was corrected and water collections were successful for the
other three stations. The bongo survey recommenced at station16 and continued
through station 36. Two ring tows for copepods were made during this first
part of the cruise.
At this point further sampling
on the grid was halted because very few pollock eggs were seen in the samples.
We decided to return to station 7 where a high concentration of eggs had
been observed. After a 7-hr steam, we reached station 37 and conducted
the MOCNESS and Tucker tows there and at station 38. In addition, a satellite-tracked
buoy was deployed at station 37 to follow the movement of the eggs.
After completing these tows,
we decided to add an additional three stations because we were ahead of
schedule. In addition, we chose to re-occupy stations 8 and 11-14 to repeat
the bongo tows; during the initial occupations of those stations, the 333-micron
codend on one side of the 60 cm net was mislabeled and was really 505 microns.
When we re-occupied station 12, we repeated the CTD cast and collected
the water samples that we had not collected earlier because of a malfunction.
Still ahead of schedule,
we steamed south to re-occupy station 39. Earlier, we had found a high
concentration of pollock eggs at this location and wanted to collect samples
with the MOCNESS and live eggs from the plankton.
After this operation, the
ship steamed around the area where a strong acoustical signal for pollock
had been noted. After locating a promising area, the midwater trawl was
deployed (station 47) and a large number of pollock was brought on board.
Ripe adults were stripped and about 50,000 fertilized eggs were incubated
onboard for the last 18 hours of the cruise. The ship returned to Dutch
Harbor on the morning of April 19.
