Stable carbon, nitrogen , and sulfur isotope data for lower trophic level producers and consumers in Kachemak Bay, AK NSF EPSCoR Fire and Ice, 2019-2020

The dataset contains stable carbon, nitrogen, and sulfur isotope data as well as carbon and nitrogen concentrations of multiple terrestrial and marine primary producers and various species of marine nearshore consumers. The data are from various watersheds in Kachemak Bay, northern Gulf of Alaska. These watersheds differ by the level of glacial cover. Samples were collected during three time periods of glacial discharge characterized as baseflow (~May/June), peak flow (~July), and post-peak flow (~September) between 2018-2023.
