Glacial meltwater and sea ice meltwater in the Prydz Bay, Antarctica
Measurements of deltaD and salinity were carried out in the Prydz Bay during two Antarctic cruises, the 13th and the 14th Chinese National Antarctic Research expeditions (CHINARE). Mass balance calculations based on deltaD and salinity showed that during the 13th CHINARE cruise, percentages of glaci...
