摘要:Seasonal variations of surface nutrients and hydrography data obtained in period (1997-2010) by the Institute of Marine Research over three transects: Fugløya-Bjørnøya, Gimsøy and Svinøy located in the Norwegian Sea have been studied.The results over the Fugløya-Bjørnøya transect show good signature of the seasonal cycle of nitrate (10.4 µmol/Kg in winter time, 0.8 µmol/Kg in bloom time, and 0.6 in post-bloom time), and temperature (4.8 ºC in winter time, 6.5 ºC in bloom time, 9.5 ºC in post-bloom time), reflecting both bloom and post-bloom periods.The Gimsøy transect shows a weak seasonal cycle of nitrate and temperature in the outer part because there is no enough data during the bloom and post-bloom period.But the middle and inner part show good seasonal cycle of nitrate and temperature during the two periods.Finally, the Svinøy transect shows good seasonal cycle of nitrate (10.1 µmol/Kg in winter time, 2.0 µmol/Kg in the bloom time, 0.9 µmol/Kg in post-bloom time), and temperature (7.1 ºC in winter time, 7.8 ºC in bloom time, 12.4 ºC in post-bloom time), during the bloom and post-bloom.
