Title:	Distribution of Marenzelleria cf. viridis (Polychaeta: Spionidae) along the Polish coast of the Baltic Sea

Abstract:	The distribution of Marenzelleria cf. viridis was studied in the Polish zone of the southern Baltic in relation to major environmental variables. Quantitative samples were collected in the 1996-2002 period from 62 stations using a 25 kg van Veen grab and a 200 kg box corer. Individuals of M. cf viridis were found to be abundant throughout the area of study down to depths of about 25-30 m, while the polychaete was encountered sporadically down to 76 m. M. cf. viridis occurred mainly on sandy bottoms, and low abundance was recorded on the silty bottoms in the Gulf of Gdańsk. The highest abundance and biomass values were recorded off river mouths in the Pomeranian Bay and the Gulf of Gdańsk, while significantly lower values were noted off the open coast. The variability of the sandy sediment properties failed to explain the polychaete’s spatial distribution pattern. On the other hand, the horizontal and bathymetric distribution of M. cf. viridis was found to correspond with variations in the water chlorophyll a content.
