Filtration activity of mollusks Mya arenaria L. (Bivalvia) in estuaries of the southern Baltic Sea
This article argues that, in the estuaries the South Baltic, the bivalve molluscs Mya arenaria are capable of consuming an average of 6.5 % of the water body primary production. A numerical assessment of the filtration rate of these molluscs shows that they can filter daily an average of 2.41 ± 1.01 m3 of water per a square meter of the river bed. During the vegetation season, molluscs can clear approximately 380 m3 of water in estuaries removing up to 558.9 ± 65.7 g of suspended organic matters...
A pool of water soluble antioxidants in some plants of the Kaliningrad region
... generative parts in the legumes with the exception of the Big-leaved Lupine (Lupinus polyphyllus (L)). The concentration of watersoluble antioxidants varied more widely in the Fabaceae than in the Gramíneae, whose antioxidant pool was more stable and less dependent on the growth conditions in terms of the distance to the Baltic Sea coast.

... time of 8 months and results of statistical method of SST superlong-term forecast, lead time — 1 year. In the first case mean-squared prediction error of SST according to independent data makes 0,5 оС, in the second case — 0,2 оС, that is much less than the reasonable mistake and meets practical requirements.
