Physical and Biogeochemical Properties of Winter Sea Ice during Pipers, Ross Sea
The PIPERS (Polynyas, Ice Production and its seasonal Evolution in the Ross Sea) cruise on N. B. Palmer into the early winter Ross Sea took place between April 11 and June 14 2017. The main objective was to investigate the Atmosphere-Ice-Ocean interactions in the Terra Nova Bay and Ross Ice Shelf co...

The cruise encountered unusual sea-ice conditions in the 2016/2017 season, where exceptionally low sea-ice summer extent was recorded Antarctica-wide as early as November 2016, which stayed below previous records of the satellite era for the rest of the austral summer. It is also a year where active primary production was evidenced within the Ross Sea and Terra Nova Bay Polynya, a few weeks before the cruise took place. We will show how these conditions have potentially affected (or not) the physical and biogeochemical properties of the sea ice cover in the Central Ross Sea and discuss the contrasts with the sea ice properties of the Terra Nova Bay polynya and the MIZ.
