Temporal distribution of phytoplankton at one station in the Northern Adriatic Sea
Temporal distribution of phytoplankton at one offshore station (45°02'8.99' N, 13°19'00.02'' E) in the Northern Adriatic Sea was investigated from May 1998 to November 2006. The investigation was performed in approximately monthly intervals at four depths (surface, 5 m, 10 m and 20 m). The study has been carried out as a part of Croatian national monitoring programme, project Adriatic. Phytoplankton species composition, species richness, diversity, taxa dominance and community dissimilarities were determined. The results were subjected to univariate, multivariate and distributional analyses. Total of 178 taxa were identified. The most abundant groups were diatoms (82 taxa) and dinoflagellates (72 taxa). Total abundance ranged from 200 cells L-1 to 1.86 x 106 cells L-1, with exception in 2003 and 2004 when total number reached 1.14 X 107 cells L-1 and 8.90 x 106 cells L-1, respectively. Taxa dominance showed prevalence of different diatom taxa with species like Thalassionema nitzchioides, Cerataulina pelagica, Nitzchia longissima being numerous and frequent during whole 8-year period while some species, like Pseudonitzchia spp. and Skeletonema costatum, had high abundance and frequency of appearance during some seasons or years. Statistical analysis showed significant difference between phytoplankton assemblages in 1998, 1999, 2000 and 2006. Results of the performed analysis indicated some seasonal community patterns, spring and autumn maxima, which were strongly emphasized during two years. In November 2003 and February 2004 diatom blooms were recorded with dominant species, Skeletonema costatum (1.12 x 107 cells L-1) and Chaetoceros socialis (8.86 x 106 cells L-1), respectively.
