This work aims to familiarize the reader with issues related to modern oceanographic measurement techniques performed by Argo autonomous profiling floats. The opportunity for this is the three years of innovative activity on the part of Argo-Poland in the Baltic Sea. Based on the experience and results acquired by the Institute of Oceanology of the Polish Academy of Sciences (IO PAN), we can say that a revolution in the Baltic Sea monitoring is underway. During three years of activity, the floats launched by IO PAN provided more than 1600 CTD profiles, including 600 O₂ profiles. Together with synoptic data from ships, data from moorings and surface buoys, the Argo float measurements are an important part of the southern Baltic monitoring system. Two Argo floats launched by IO PAN collected enough data to determine the dynamics of the oxygen content in various layers, the extent of hypoxic and anoxic zones, and to detect small baroclinic inflows to the Gotland and Gdańsk Deeps.
