attribute NC_GLOBAL acquisition_description String Methods
At each station, a Nordic 264 rope trawl built by Nor'Eastern Trawl Systems,
Inc. was towed in surface waters by a chartered fishing vessel (F/V Sea Eagle
in 2000 and F/V Frosti in 2002). It was towed with about 300 m of warp for 30
min at 1.5 m/sec with a pair of 3.0-m foam-filled trawl doors and 90.7-kg
weight chains to spread the mouth open. Except for two mid-water trawling
events, six A-4 Polyform floats were clipped to wingtips and the headrope to
fish the trawl at the surface. The trawl has a maximum mouth opening of
approximately 30-m wide x 18-m high. Mesh sizes ranged from 162.6 cm in the
throat of the trawl near the jib lines to 8.9 cm in the codend. To maintain
catches of small fish and squid, a 6.1-m long, 0.8-cm knotless liner was sewn
into the codend. All but several tows were 30 min in duration. The majority of
trawls were done during daytime, although a few were done at dawn and dusk and
two diel series were completed in 2002.

All juvenile salmon caught were immediately frozen for laboratory analysis.
All fish, squid, and large jellyfish caught were counted and up to 50 of them
measured at sea. However, when very large catches of a species occurred, a
subsample was measured, counted, and weighed; remaining individuals were mass
weighed and total count estimated from known number/kg. When the trawl was
full, weight of the total catch was estimated and species counts derived from
a subsample as just described. Catches were standardized to number per 106 m3.

In the laboratory, all frozen juvenile salmonids were weighed prior to
dissections for subsamples of growth, condition, pathology, genetic analysis,
and food habits. As large subadult/adult salmonids were released shortly after
being captured, their weights were estimated from length-weight regressions.
Also, common species of non-salmonid fish and squids not weighed at sea had
their weights computed from length-weight regressions where their lengths were
available. For those individuals without length data, station or cruise-wide
average of number/kg was used to estimate weights.

Goal: To understand the effects of climate variability and climate change on the distribution, abundance and production of marine animals (including commercially important living marine resources) in the eastern North Pacific. To embody this understanding in diagnostic and prognostic ecosystem models, capable of capturing the ecosystem response to major climatic fluctuations.
Approach: To study the effects of past and present climate variability on the population ecology and population dynamics of marine biota and living marine resources, and to use this information as a proxy for how the ecosystems of the eastern North Pacific may respond to future global climate change. The strong temporal variability in the physical and biological signals of the NEP will be used to examine the biophysical mechanisms through which zooplankton and salmon populations respond to physical forcing and biological interactions in the coastal regions of the two gyres. Annual and interannual variability will be studied directly through long-term observations and detailed process studies; variability at longer time scales will be examined through retrospective analysis of directly measured and proxy data. Coupled biophysical models of the ecosystems of these regions will be developed and tested using the process studies and data collected from the long-term observation programs, then further tested and improved by hindcasting selected retrospective data series.
