Seawater temperature and density were measured from the surface to 200 m depth (seafloor depth permitting) at each oceanographic station using a CTD (Seabird SBE 19 SeaCAT and General Oceanics Mark III).
A Multi-Response Permutation Procedure (MRPP) with the Bray-Curtis distance measure was calculated with the PC-ORD software to test for statistically significant differences between the groups of oceanographic stations formed in the CCA (McCune et al., 2002).
The ordination diagram shows two groups of oceanographic stations (Fig 10a).
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.
In this study the metal content was analyzed only at three oceanographic stations
, generating a limited amount of information.
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.m.
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.
