Seasonality in an Arctic fjord ecosystem: Hornsund, Spitsbergen
Based on two complete years of marine ecological surveys (1981-82 and 1984-85) carried out in the Hornsund fjord on southern Spitsbergen (77N), the seasonal variation of physical and biological processes is presented. Physical parameters reflect the strong seasonality of sun radiation, while water s...
