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...

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).

Meanwhile, the percentages were 1.53%-3.98% and -3.80%-4.52% during the 14th CHINARE cruise. We depicted plots showing the horizontal distributions of glacial meltwater and sea ice meltwater, and found a footprint of Circumpolar Deep Water (CDW), which may suggest a strong upwelling in this regime. We also noticed a butterfly-like image in the plot, which resulted from two adjacent water masses. It is interesting to note that the butterfly-like image deflected anticlockwise with depth.
