Opis:: The paper analyses experimental measurements of laser-induced fluorescence (LIF) spectra in different seawaters. The fluorescence parameters, calculated from LIF spectra as the ratio of the integrals of fluorescence and Raman signal intensities, provide information about the relative changes in the concentrations of fluorescing molecules. Gathered during several cruises in 1994–2004 in the Baltic and Nordic Seas, all the data are presented as scatter plots of the fluorescence parameters of chlorophyll a (Chl a) and coloured dissolved organic matter (CDOM). Satisfactory correlations between these two parameters were found a) for open Nordic Seas waters, b) for the southern Baltic in blooming periods only, and c) for the Gulf of Gdańsk in non-blooming periods only.

Opis:: For many years the Nordic Seas have been the subject of research into ocean circulation carried out by the Institute of Oceanology PAS, especially the inflow of Atlantic water and the intensive turbulent mixing of these waters with Arctic and shelf waters. Ocean currents affect various biological processes, among them the supply of organic matter and oxygen, which constitute the foundation for the unique flora and fauna of the Svalbard islands. Spectrophotometric examinations of surface waters using an M32 B spectroflu- orophotometer (LDI Ltd.) were carried out repeatedly during Arctic cruises on board r/v ‘Oceania’. The results presented in this paper come from the AREX campaigns of 2003 and 2006. Analysis of the chlorophyll a fluorescence excitation spectra recorded shows an increase in phytoplankton abundance and the changes in the spatial distribution of the phytoplankton species characteristic of Atlantic, Arctic and shelf waters. The spatial patterns of the phytoplankton pigments and their abundance were compared with the physical characteristics of water masses. The analysis confirmed that phytoplankton species move together with the Atlantic water as this flows into northern latitudes.

Opis:: Several sea and laboratory experiments have been carried out to detect and determine the fluorescence characteristics of seawater and its natural fluorescing components and to analyse the influence of oil in the surface water layer on the lidar-induced return signal. The aim of the laboratory investigations was to create a database of different natural water types and of water polluted with Petrobaltic oil. During the r/v ‘Oceania’ cruise in the southern Baltic Sea two lidar methods were applied simultaneously to detect and analyse the influence of the fluorescence emission of oil on the fluorescence spectrum of seawater. Detection of oil pollution can be used to correct the fluorescent factors of fluorescing components on the basis of natural seawater fluorescence spectra.
