Conductivity, Temperature, and Depth (CTD) Data from the 2020 Gulf of Alaska International Year of the Salmon Expedition

CTD (conductivity, temperature, density) data collected in the Northeast Pacific Ocean during the Gulf of Alaska (GoA) expedition in 2020 using a SeaBird 19 CTD equipped with fluorescence and oxygen sensors was deployed to 300 m depth at 1 m s-1. Data were processed onboard and binned into 1 m depth intervals. These data were collected as part of the International Year of the Salmon (IYS) Gulf of Alaska High Seas Expedition conducted in March to April 2020, to further improve the understanding of factors impacting salmon early marine winter survival.
