Description

This dataset contains the trawl and specimen data collected aboard the R/V Bell M. Shimada for the IYS survey in 2022 in the North Pacific Ocean. This package contains three components; event, catch, and specimen data. The event data contains all of the sampling event information, including time, location, and duration. All dates and times are in UTC. The catch data contains all of the catch records, as counts, weights, and lengths, for each species/taxa at each station. The sampling method for every catch weight should be total weight, and all weights are in kilograms. The specimen data contains individual lengths (in cm) and weights for sampled individuals from each station.

Sampling Description

Study Extent

Surface trawl operations were conducted at 22 stations in the Northeastern Pacific Ocean.

Sampling

Surface trawl operations were conducted in approximately the top 50 meters of the water column, using a Cantrawl model 400/580. Tows were between 60 and 120 minutes in duration. Total species catch weight (kg) and the total count, weight and length for each identified species was recorded.

Method steps

Species were identified onboard the vessel to the lowest taxonomic rank possible or practical, and individual lengths (cm) and wet weights (kg) were recorded.
