Benthic Marine Pollution Around McMurdo Station, Antarctica

Listed in NASA Earthdata CMR

Benthic sediments and animals are highly modified by human activities at McMurdo Station, the largest human settlement in Antarctica.

Description

The quantity of anthropogenic debris, contamination of marine sediments with hydrocarbons and metals, and gross changes in benthic communities are largely confined in Winter Quarters Bay, adjacent the former dump site and the ice dock used by visiting ships. Metal levels are mostly high within the bay, but are not greater than in the most polluted temperate habitats.

Levels of anthropogenic chemicals are significantly higher in the back bay compared to stations established at different distances from the bay (along three potential contamination gradients), including reference sites many kilometers away.
