Hydrogen, carbon and nitrogen isotopes trace biogeochemical subsidies in glacier runoff into coastal marine food webs

To demonstrate connectivity between terrestrial and marine ecosystems, we sampled stable and radiogenic isotopes to estimate the relative contribution terrestrial-derived organic matter (OM) via glacier runoff to marine food webs. This spreadsheet dataset contains isotope ratios of water, dissolved organic matter (DOM), dissolved inorganic matter (DIC) and particulate organic matter (POM), mussels, marine sponge, marine snail, shrimp, plankton, fish and seabirds from the Prince William Sound and Aleutian Islands during the peak glacier melt in summer (July-August 2012 and 2013). Data are provided in a CSV file (nprb-1206-glacier-isotope-data.xml), and the full metadata record for this dataset is provided in the FGDC-compliant XML file (nprb-1206-glacier-isotope-metadata.xml) archived as part of the dataset.
