Abstract

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 Nan...

Samples were collected in Resurrection Bay within the inner basin at RES2.5 (60° 1.5’ N, 149° 21.5’ W; 298 m deep) at approximately biweekly intervals aboard the R/V Nanuq between January 5th and March 24th, 2023. Collection and sample processing are described in detail in Block (2024). Vertical profiles of water temperature, salinity, and fluorescence were measured from 280 m to the surface using a CTD (SBE25 SeaLogger) and WetLabs chlorophyll α fluorometer mounted on an SBE55 rosette with six 4-L Niskin Bottles. Water was collected at discrete depths (surface, 10, 20, 30, 40, 50, 150, and 280 m) for characterization of the phytoplankton and microzooplankton community. Two casts were required to collect all water samples.
