The Analysis of Selected Events

The Institute of Marine Research and later the Baltic Sea Research Institute in War-nemiinde were laigely involved in investigations of the analysis of specific inflows of highly saline water and the study of the water renewals in the central Baltic, as well as on the stagnation periods following these events in the central Baltic deep water. 

Fonselius (1962) started the detailed description of the effects of MBIs in the central Baltic deep water. He identified MBIs studying long-term variations, mainly of salinity in the Bornholm Basin. Fonselius described the dynamic processes between the Baltic deep basins after MBIs, the importance of the Bornholm Basin as buffer basin, and the overflow of the Eastern Gotland Basin in intermediate depths downstream into the Landsort Deep. 

Only few measurements of inorganic phosphorus were carried out in the Baltic Sea before 1957. Because of the greater amount of data on phosphate since then, Fonselius introduced the variations of this nutrient into the discussion of the effects of MBIs (Fonselius, 1962). For 

he carried out a detailed study on variations in the phosphate regime of the central 

Baltic deepwater during the stagnation and the turnover caused by MBls.
