“…The most important factors are as follows: the quantity and quality of OM that reaches sediments, water depth and related time of sinking of suspended particulate matter in the water column, resuspension and mixing of surface sediments associated with the bioturbations and/or dynamics of bottom water, sediment accumulation rate, oxygen conditions in the water column and sediments, and the rate and path of OM mineralisation (Jensen et al, 1995;Heiskanen and Tallberg, 1999;Benitez-Nelson, 2000;Graca et al, 2006;Rullkötter, 2006;Łukawska-Matuszewska and Burska, 2011;Rydin et al, 2011). In the following paragraphs, distribution patterns of C, N, P and S and their molar ratios in sediments in the Gulf of Gdansk will be discussed.…”
