Northern high-latitude deltas are hotspots of biogeochemical processing, terrestrial-aquatic connectivity, and, in Alaska’s Yukon-Kuskokwim Delta (YKD), tundra wildfire. Yet, wildfire effects on aquatic biogeochemistry remain understudied northern delta regions, thus limiting a more comprehensive understanding high latitude cycles. In this study, we assess impacts summertime YKD using multi-yea...
