Description 
Summary

The aim of the researches is to evaluate oxygen conditions in different regions of the Baltic Sea. In accordance with the national and international Baltic Sea monitoring (HELCOM) programme monitoring cruises have been fulfilled with Lithuanian research vessels 'Okeanografas', 'Vetra', 'Vejas'. Since 1972 investigations have been carried out in a wide net of stations in national and international waters (including Baltic Proper, Gdansk Basin, Bornholm Basin, Arkona Sea, Gotland Basin, Landsort Deep and Faro Deep), later the net of stations became more narrow and since 2000 research in the Baltic Sea has been defined more exactly and has been carried out only in the exclusive economic zone of Lithuania. Oxygen investigations are carried out during every season at a constant network of stations in standard sea water horizons. In 1972-1992 research was performed at 35 stations, 1993-1999 - 14 stations and since 2000 - 5 stations. The data are fully quality controlled. Systematic certification of laboratories, participation in an international intercalibrations, internal control, introduced managing system for researches' quality, use of high quality reagents determine quality of data. All data is stored in archive (in table forms on paper) and is saved on hard disk.
