Biogeochemical Subsidies from Glacier Runoff into Alaska Coastal Marine Food Webs, Gulf of Alaska, 2012-2013

To demonstrate connectivity between terrestrial and marine ecosystems, we used stable (δ13C, δ15N, δ2H) and radiogenic (∆14C) isotopes to estimate the relative contribution of glacier runoff and terrestrial-derived organic matter (OM) to marine food webs. This da...

Description
Summary:To demonstrate connectivity between terrestrial and marine ecosystems, we used stable (δ13C, δ15N, δ2H) and radiogenic (∆14C) isotopes to estimate the relative contribution of glacier runoff and terrestrial-derived organic matter (OM) to marine food webs. This dataset contains information on isotopic signatures from dissolved organic matter (DOM), dissolved inorganic matter (DIC) and particulate organic matter (POM), mussels, plankton, fish and seabirds near tidewater glaciers during the peak melt in summer 2012-2013 in Prince William Sound and the Western Aleutians, Alaska.
