Chlorophyll-a concentrations from research cruises for the Northern Gulf of Alaska (NGA) LTER site, 2018-2022
This dataset consists of chlorophyll-a concentrations obtained during NGA-LTER research cruises conducted in the Gulf of Alaska during spring, summer and fall, starting in 2018. The data were collected to determine whether chlorophyll-a concentration varies with time (season), location and depth. In...

The data were collected to determine whether chlorophyll-a concentration varies with time (season), location and depth. Included in this dataset are concentrations broken down by size fraction: <20 µm, >20 µm, and total (all as µg/L), as well as the total amount of phaeopigments (µg/L), the fraction of the chlorophyll >20 µm, and integrated chlorophyll. Chlorophyll concentrations were measured in the upper 75 meters of the water column. Excel spreadsheets were converted to CSV files for preservation. These data are part of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) program. The LTER program is a National Science Foundation–funded network of 28 sites nationwide that focus on the influence of long-term and large-scale phenomenon on ecosystems. Additional funding for sampling is provided by the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOS) via the Gulf Watch Alaska program.
