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

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.

本数据集包含2020年阿拉斯加湾（Gulf of Alaska, GoA）科考航次于东北太平洋海域采集的CTD（conductivity, temperature, density，电导率、温度与密度）数据。本次航次搭载配备荧光与溶解氧传感器的SeaBird 19型CTD，以1 m·s⁻¹的下沉速率将设备布放至300 m水深。所采集数据于航次船上完成现场处理，并按1米深度间隔进行分层归并。本数据系2020年3月至4月开展的国际鲑鱼年（International Year of the Salmon, IYS）阿拉斯加湾公海科考航次的采集成果之一，旨在进一步厘清影响鲑鱼海洋越冬早期存活率的相关因素。
