Climate warming is accelerating erosion along permafrost-dominated Arctic coasts. This results in the additional supply of organic matter (OM) and nutrients into the coastal zone. In this study we investigate the impact of coastal erosion on the marine microbial community composition and growth rates in the coastal Beaufort Sea. Dissolved organic matter (DOM) derived from three representative glacial deposit types (fluvial, lacustrine, and moraine) along the Yukon coastal plain, Canada, were used as substrate to cultivate marine bacteria using a chemostat setup. Our results show that DOM composition (inferred from UV-Visible spectroscopy) and biodegradability (inferred from DOC concentration, bacterial production and respiration) significantly differ between the three glacial deposit types. DOM derived from fluvial and moraine types show clear terrestrial characteristics with low aromaticity (S r : 0.63 ± 0.02 and SUVA 254 : 1.65 ± 0.06 L mg C −1 m −1 & S r : 0.68 ± 0.01 and SUVA 254 : 1.17 ± 0.06 L mg C −1 m −1 , respectively) compared to the lacustrine soil type (S r : 0.71 ± 0.02 and SUVA 254 : 2.15 ± 0.05 L mg C −1 m −1 ).
