This data set contains the at sea trawl and specimen data collected aboard the R/V TINRO for the IYS survey in 2022 in the North Pacific Ocean. Collected data offers important insights to achieve further understanding of changing ocean conditions and their effects on salmon in the open ocean. This data package contains 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 and weights, for each species/taxa at each station. The specimen data contains individual lengths and weights for sampled individuals from each station.Sampling Description
Study Extent
Surface trawl operations were conducted at 32 stations in the North Pacific Ocean.Sampling
Trawl nets were deployed at each station and towed at 4-5 knots for one hour in the top 50 meters of the water column with headropes near the water surface. Total catch was sorted by species, which were identified to the lowest taxonomic rank possible or practical. Total species catch weight (kg) was recorded and the total count 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 and wet weights were recorded.
