The Argo Poland is a component of global array of temperature/salinity profiling Argo floats.

The Argo array amounts to 4000 floats at present. About 800 new floats are deployed per year (including circa 250 in frame of the Euro-Argo).

The data come from battery-powered autonomous floats that spend most of their life drifting at depth where they are stabilised by being neutrally buoyant at the "parking depth" pressure by having a density equal to the ambient pressure and a compressibility that is less than that of sea water. Satellites determine the position of the floats when they come to surface, and receive the data transmitted by the floats.

The Polish Argo programme is carried out by the Institute of Oceanology Polish Academy of Sciences (IOPAS). So far thirteen Argo floats were deployed by Poland. Two in June 2009 and June 2010, one in July 2012, two in July 2014 in the Greenland Sea during the Arctic cruises of the IOPAS research vessel r/v Oceania. Three IOPAS floats were deployed in the Norwegian Sea aboard r/v Horyzont II in September 2015 and two in June 2016 also in the Norwegian Sea aboard r/v Oceania. In November 2016 also aboard r/v Oceania the first Polish Argo float in the Baltic Sea was launched

Data received from the IOPAS floats and another Argo data sets were used to construct the mean hydrographic fields in the West Spitsbergen Current (WSC) for a comparison with the WSC structure obtained from the shipborne hydrographic measurements.
