Carbonate system properties in the Gerlache Strait, Northern Antarctica Peninsula
International audience Hydrographic and carbonate system properties were determined in the Gerlache Strait—a coastal site in the Northern Antarctic Peninsula (NAP)—during early February 2015. It was part of an effort to monitor changes in marine inorganic carbon chemistry in Antarctic coastal zones....
