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 (IOPAN). Since 2009 our Institute has deployed twenty-one floats. Fourteen of them were launched in the Nordic Seas from the board of r/v Oceania and three in the same region aboard r/v Horyzont II. Since November 2016, also aboard r/v Oceania, IOPAN has launched four floats in the Baltic Sea.
Data received from the IOPAN 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.
