The sampling was performed on board the research vessel R/V "AGOR Vidal Gormaz" between October 27th and November 26th 2009, where seven oceanographic stations
were sampled with a box corer (box size 30x30x40 cm) (Fig.
As Sampson sailed north, Leigh Smith established several oceanographic stations, recording water temperatures at various depths and collecting seabed samples.
From there Leigh Smith headed northeast along the edge of the pack ice, establishing 14 oceanographic stations along the way and again finding a layer of warmer water at depth.
Samples were obtained at 52 oceanographic stations
distributed along 8 transects perpendicular to the coast, but biological samples were not obtained in the stations A2 1 and A22.
Oceanographic data and zooplankton samples were obtained at 40 oceanographic stations
distributed throughout the Magellan Strait and in the adjacent channels and fjords (52[degrees]-56[degrees]S) during the CIMAR 16 Fiordos cruise which took place between 11th October and 19th November 2010 on board the R/V Abate Molina.
In situ measurements from fixed coastal and oceanographic stations were compared with daily Level 1b local area coverage (LAC) data from NOAA-AVHRR systems acquired through the Argentine National Commission of Space Activities (CONAE).
Afterwards, fixed and oceanographic stations were considered separately, as well as the different satellites and overpass times.
The sample plan consisted of profiles perpendicular to the coast, with oceanographic stations 20 n.
The oceanographic stations associated with this group of species probably delimit a transition zone between the cold waters of the Sub-Antarctic Shelf Water and the warm waters of the Tropical Water.
