Ocean Acidification - Effects of melting glaciers are part of PWS research
Ocean scientists who have been studying Prince William Sound for the past five years are hoping to determine by fall the maximum distribution of glacial melt water and its impact on the saturation state of carbonate minerals.
Ocean chemistry: Fingerprints of a trace nutrient
Lack of dissolved iron in the sea limits biological productivity and the uptake of carbon dioxide. The sources of dissolved iron in the North Atlantic Ocean have been identified from isotopic variations of this trace nutrient.
