Studies have documented the presence of organic contaminants in Arctic marine environments due to local point sources, but little long-term data is known of the recovery process once those contaminants are removed. In this study, natural recovery of a local marine food web from a historic terrestrial source of polychlorinated biphenyls (PCBs) at Saglek Bay is examined. PCBs were measured in marine sediments, shorthorn sculpin (Myoxocephalus scorpius), and black guillemots (Cepphus grylle) to assess ecosystem recovery over an eight-year period after cleanup of the source. Surface sediment measurements indicate decreases in both the extent and average concentrations of PCBs throughout Saglek Bay. Sculpin collected near the former contaminated beach in 2006 had significantly lower PCB burdens than those collected in 1998/ 99. PCB levels have also decreased significantly in black guillemot nestlings collected from the former contaminated beach area, as well as Island (6-8 km from the source) and Reference (greater than 18 km from the source) locations. This study demonstrates the utility of using indicator species, especially the black guillemot, to monitor PCB uptake in benthic food webs. The rapid decreases in the physical and biotic PCB concentrations from the local ecosystem at Saglek Bay demonstratethe efficiency with which natural ecosystem recovery can take place in a highly energetic coastal marine environment once a chronic contaminant source is removed.
