Opis:
Aerosol samples were collected in May 1997 at a routine off-shore measurement station in the Gdańsk Deep region and at Hel, the latter being a coastal station situated at the tip of the Hel Peninsula. Concentrations of NO− 3 , Cl−, Na+, Mg2+, K+ and Ca2+ were measured simultaneously at both stations. The sea influences the chemical composition of aerosols in the coastal zone of the Gulf of Gdańsk regardless of season, time of day or direction of advection. Sodium chloride was always present in aerosols in the form of large particles originating from seawater. Besides the marine chloride and nitrate, additional amounts of these ions could have been of terrigenous origin. Sodium and chloride concentrations were dominant in the total mass of aerosols at both stations; however, these concentrations were three times higher at the marine station. Similarly, the concentrations of ions originating from seawater, like magnesium and calcium, were, on average, three times higher at the marine station. The chemical composition of aerosols and air over the Gulf of Gdańsk was modified through the evaporation of chloride from the marine salt particles in reactions with gaseous nitric and sulphuric acids. A certain deficit of chloride versus sodium ions was noted. At the marine station the Cl−/Na+ ratio reached 0.89 ± 0.2, on average, while over the land station it was 0.93 ± 0.25, i.e. lower than the seawater standard.

Opis:
The idea of the study was to describe short-term and seasonal variations in the composition and abundance of zooplankton in the coastal area of the Gulf of Gdańsk at two shore stations and the influence of selected environmental factors (temperature, salinity, wind velocity) on it. The studies were based on material collected in the shallow waters of the Gulf of Gdańsk from stations located by the Marine Promenade (Bulwar Nadmorski) in Gdynia and the pier in Sopot. Samples were collected in 2001 mainly at weekly intervals using an open-type plankton net. Environmental parameters were measured at the same time. The zooplankton at the Gdynia and Sopot stations consisted of 30 taxa; Rotatoria, Copepoda and meroplankton were dominants. There was a much higher percentage of Rotatoria and a lower percentage of meroplankton at Sopot than at Gdynia. Considerable differences were apparent in the numbers of particular groups of zooplankton at these stations in the same periods. Simpson’s biodiversity index, here based on the zooplankton of the shallow waters off Gdynia and Sopot, was relatively high most of the time. Diversity of mesozooplankton was greatest in July and October. There was a significant correlation between the abundance of mesozooplankton and environmental factors in the case of cladoceran and polychaete larvae. Frequent studies at stations located close to each other illustrate the highly dynamic range of variations occurring in the coastal area: the concentrations of particular organisms fluctuated very considerably from one week to another, even by a factor of several dozen. Nevertheless, the statistically mean numbers of zooplankton at both stations are comparable.

Opis:
To determine the atmospheric concentrations and size distributions of particulate selenium (Se), aerosols were collected by air filtration and impactor sampling at the Kap Arkona coastal weather station on the Island of R¨ugen.T otal reflection X-ray fluorescence analysis was used to determine Se and numerous other elements as well.The dependence of the Se concentration on the wind direction and the results of a regression analysis indicated that Se associated with sub-micron particles is mainly derived from anthropogenic sources.The pronounced relationship between Se and Cu indicated that copper smelting is a major source of atmospheric selenium. A marine Se contribution was identified for particles larger than 2 μm.
