CTD (temperature, salinity and fluorescence) from bi-weekly vertical profiles in Resurrection Bay, AK from January to March of 2023

The Gulf of Alaska is a highly seasonal environment that is characterized by an order-of-magnitude increase in copepod biomass in the photic zone between winter and spring. The study focused on copepod recruitment to characterize species-specific naupliar production. Concurrent environmental monitoring included approximately bi-weekly vertical profiles of temperature, salinity and fluorescence were recorded at an established station (RES2.5) in Resurrection Bay, AK. Day-trips aboard the R/V Nanuq were conducted approximately bi-weekly in Resurrection Bay, AK during January to March, 2023.阿拉斯加湾（Gulf of Alaska）是高度季节化的海洋生境，其典型特征为冬季至春季期间，透光带（photic zone）内桡足类（copepod）生物量出现数量级的增长。本研究聚焦桡足类种群补充过程，旨在阐明各物种特异性的无节幼体（naupliar）生产特征。同步开展的环境监测工作中，研究人员在阿拉斯加州复活湾（Resurrection Bay, AK）的固定站位RES2.5处，约每两周记录一次温度、盐度与荧光值的垂直剖面数据。2023年1月至3月期间，研究团队约每两周搭乘“纳努克号”科考船（R/V Nanuq）在复活湾开展日间科考航行。
