Descripción
During the PS81 (ANT-XXIX/4) expedition of icebreaking RV Polarstern from Punta Arenas to the North Scotia Sea Ridge, South Georgia, and the South Sandwich Trench and back to the Falkland Islands from 22 March till 26 April 2013, three independent datasets were collected in order to establish the quantitative at-sea distribution of marine mammals and seabirds.

Métodos de muestreo
Transect counts were devoted to seabird and marine mammal observation. The transect counts were lasting half an hour, without width limitation from the bridge at 18 m above sea level on a continuous basis, light and visibility allowing (see description and discussion in Joiris 2007 ; Joiris and Falck 2010 ). The animals were detected with the naked eye, and observations confirmed and complemented with binoculars (10 9 42) when useful; photographic documents were also used, especially for species difficult to identify. Results are presented as basic unmodified data, i.e. numbers encountered per half-an-hour transect count. Density was also calculated on the basis of specific detection limits established by this team in function of size, colour and behaviour (jizz) (Joiris 2007 ; Joiris and Falck 2010 ) and mean ship’s speed: 10 knots in open water and 5 knots in ice covered areas. Water temperature and salinity were continuously recorded on board Polarstern with a thermo-salinometer at subsurface sampling (keel - 10 m). Ice cover was evaluated by us from the bridge and expressed as % coverage within an approximate range of 500 m around the ship.
