Short summary
Shallow coastal waters are increasingly experiencing increased nutrient loading. Sediment algae within these systems are responsible for a large portion of C production, but we have limited knowledge of what happens to sediment microbial processing of MPB-C under increased nutrient conditions. This work examines how C-processing pathways change after increased short-term nutrient exposure, finding shifts in processing between microbial groups and increased export of algal C from the sediment.
