2.0. OPERATIONS
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. All other operations will
be conducted in accordance with the Standard Operating Instructions.
2.1. SUMMARY OF ACTIVITIES:
A schematic overview of the cruise and the plan for coordination with
the Wecoma are shown in Appendix 1.
Phase 1. The ship will proceed from Dutch Harbor and do a short ichthyoplankton
survey of the region between Unimak Pass and the Shumagin Islands, consisting
of about 30 stations (see Appendices 8 and 9: newly added to this version
of cruise plan). Scientists Brown, Britt, Busby and Cartwright will be
on this portion of the cruise, with scientist Brown acting as field party
chief. The ship will then proceed to pickup the remaining scientific party
and the Munson in Women's Bay at the USCG station, Kodiak Island on May
24. Line 8 will be sampled en route to the next sampling area. Line 8 sampling
will include 20 and 60 cm bongos, and CTDs with water samples for microzooplankton,
chlorophyll and nutrients. Line 8 station positions are shown in Appendix
3. If time is available before phase 2, ichthyoplankton in Uyak Bay will
be sampled using the Freeman and the Munson deployed from the Freeman.
Sampling locations are shown in Appendix 2
Phase 2. A pre-survey of the Shelikof Sea Valley will be conducted between
the Semidi Islands and Kodiak on May 26-27 prior to the arrival of the
Wecoma in the main grid region. The standard sampling gear will be the
60cm bongo with 505um mesh netting. The survey will proceed from the area
of the Semidi Islands towards the northeast. It is anticipated that this
portion of the survey will take 2 d . A map of the pre-survey stations
is shown in Appendix 4. Station positions are shown in Appendix 5, in bold
type.
Phase 3. After the pre-survey is conducted, the Freeman will coordinate
sampling with the Wecoma, which is scheduled to arrive in the area of the
Shelikof Sea Valley about May 28. The Wecoma will occupy a standard grid
of stations and conduct rough counts of larval pollock abundance. At stations
with high larval abundance, the Freeman will conduct "adaptive sampling",
which is a small-scale grid of stations clustered around the station of
high abundance. Sampling will continue on the grid in an "upstream"
direction until a cut-off level is attained. That cut-off level of larval
pollock abundance will be determined from the pre-survey in Phase 2. All
sampling will be conducted with bongo gear. An example of the adaptive
sampling plan is shown in Appendix 6.
Phase 4. Bongo stations will be established in the nearshore coastal
region between Cape Kubugakli and Chignik Bay, or in Uyak Bay. Sampling
will be conducted from a small vessel deployed from the Freeman. It is
anticipated that this sampling will take 2 days. Station positions for
the nearshore sampling are shown in Appendix 7.
Phase 5. As time allows, sampling of the vertical distribution of pollock
larvae will be conducted using the Mocness sampling gear. Sampling of pollock
larvae will be from 150 m to the surface. In the event of a storm, a break
in any of the prior Phases may be called for by the Chief Scientist in
order to opportunistically monitor before and after storm conditions. Storm
monitoring will include CTD's (nutrients, chlorophyll and mzp), Mocness
and bongo tows.
Station positions and maps of the grid stations for the ichthyoplankton
survey are found in the Appendix. The most likely stations to be occupied
are noted in the Appendix, however, the stations occupied from the list
and their order of occupation will be established on a day to day basis.
The chief scientist will attempt to notify the bridge of stations to be
occupied 24h in advance. The nearshore ichthyoplankton stations are approximate
locations at this time. More details will be provided at a later date.
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)
MARMAP bongo tow (SOI 2.2.2)
Bongo larval condition tow (SOI 2.2.3)
Live zooplankton ring net tow (SOI 2.2.4)
Mocness tows (SOI 2.2.5)
CalCOFI vertical egg tow (SOI 2.2.6)
Chlorophyll samples (SOI 2.2.10)
Satellite tracked drifter buoy (SOI 2.2.11)
EK500 monitoring (SOI 2.2.12)
ADCP (SOI 2.2.13)
Radiometer (SOI 2.2.14)
Ichthyoplankton sampling from the Munson will be conducted in bays and
nearshore regions that are too shallow for the Freeman to sample. The gear
used on the Munson will be the 60cm bongo with 505 mesh. The tow will be
9-15 minutes, stepped obliquely in layers depending on the bottom depth.
For example if the bottom depth is 20m, the gear will be lowered as usual
to 5m off bottom, towed there at 15 m for 3 minutes, raised to 10 m and
towed for 3 minutes and raised to subsurface (1 m) and towed for 3 minutes.
The boat will be expected to be away from the Freeman for up to 8 h. Depending
on conditions, and requirements 1-2 crew members and 1-2 scientists will
be onboard.
