[en] 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 coastal polynyas. The cruise
however extended these polynyas studies to a series of ice stations transects “in” and “out” of the Ross Sea. It
involved a large set of multidisciplinary activities aiming at the detailed documentation of processes across the
ocean-ice-atmosphere continuum. This paper presents the basic physical (Temperature, bulk salinity, brine
volume, Rayleigh number) and biogeochemical properties (water stable isotopes, Chl-a) of the sea ice cover at
27 ice stations. 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.
