Whole Curonian Lagoon in the southeast Baltic Sea during the period 1962-1992 (data set limits: 54 54 - 55 44N; 20 37 - 21 16E); Northern Curonian Lagoon since 1993 (data set limits: 55 16 - 55 44N; 21 01 - 21 17E)

Dissolved oxygen parameters in the water column

Discrete water samplers; dissolved gas sensors

The aim of the research is to evaluate oxygen conditions in different regions of the Curonian Lagoon. In accordance with the national Curonian Lagoon monitoring programme, oxygen investigations from 1962 to 1979 were carried out three times a year (spring, summer, autumn), since 1980 - every month according to HELCOM methods at surface and bottom water layers. From 1962 to 1992 the investigations of oxygen were carried out in the whole Curonian Lagoon, since 1993 - in the north part of the water body which belongs to the Lithuania during the complex research expeditions by the cutter 'Gintaras'. The data are fully quality controlled. Systematic certification of laboratories, participation in international intercalibrations, internal control, introduced managing system for research' 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.
