| 320 | |a The East Siberian Arctic Shelf (ESAS) is a significant source of atmospheric methane, and the coastal Laptev Sea near the Lena River Delta is a documented hotspot for methane seepage. While anaerobic oxidation of methane (AOM) acts as a critical biofilter, the specific pathways and electron acceptors driving this process in the unique river-influenced settings of the Arctic remain poorly understood. The Lena River delivers substantial terrigenous nutrients to this region, contributing approximately 10 % of the total riverine nitrogen and 17 % of the iron input to the Arctic Ocean. This study examines the hypothesis that these nutrient fluxes play a crucial role in regulating AOM, a key process mitigating methane emissions. We compared the geochemical conditions at active methane seep sites and background areas, with a special focus on nitrogen and iron compounds in bottom and pore waters | ||
