Fish Nutritional Quality, Biomarkers, Communities, and Environmental Data from the Nearshore Beaufort Sea, Alaska, 2021-2023

This data release contains information derived from fishing efforts and sampled fish from the nearshore Beaufort Sea, Alaska, 2021-2023, as part of a study investigating red-throated loon productivity and diet. The datasets include six tables comprising 1) catch per unit effort (CPUE) data, 2) field-measured lengths of fish (mm), 3) the energy density (kJ/g) and whole-body energy (kJ) of 16 species of forage-sized fish (≤200 mm), 4) taxonomic details of captured fish, 5) temperature (°C), raw electrical conductivity (μS/cm), and salinity (psu) as recorded by data loggers, and 6) the specifications of surface trawl fishing sets.
