Title:	Bio-physico-chemical manifestations of upwellings along the Hel Peninsula (the Baltic Sea) - preface
Authors:	Szymelfenig Maria
Abstract:	Upwelling is a vertical upward current, which raises the waters from deeper layers to the sea surface. Such phenomenon could occur both on the open oceanic waters and in shallow, coastal sea waters. Although upwelling is characterized by low vertical velocities as compared to the horizontal ones, it results in considerable changes in surface sea layer. Coastal upwellings are usually more intense than those occurring on the open waters since their vertical current velocities are higher (Bowden 1983). The advanced investigations on Atlantic and Pacific upwellings showed that the waters upwelled from deeper sea layers differed from the surface waters in almost all physico-chemical and biological properties e.g. temperature, salinity, the concentrations of oxygen, chlorophyll a and nutrients as well as phyto- and zooplankton taxonomic composition.
