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 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.

为阐明陆地与海洋生态系统间的连通性，本研究采用稳定同位素（δ¹³C、δ¹⁵N、δ²H）与放射成因同位素（∆¹⁴C），估算冰川径流与陆地来源有机质（OM）对海洋食物网的相对贡献。本数据集收录了2012-2013年夏季融冰高峰期，阿拉斯加威廉王子湾与阿留申群岛西部潮汐冰川周边区域的同位素特征数据，涵盖溶解态有机质（DOM）、溶解态无机物（DIC）、颗粒态有机质（POM）、贻贝、浮游生物、鱼类及海鸟的相关同位素信号。
