Investigations on the plankton community of Balsfjorden, Northern Norway. The phytoplankton 1976–1978. Environmental factors, dynamics of growth, and primary production

摘要: Abstract Measurements of incident and sub-surface radiation, plant nutrients, particulate carbon nitrogen, ‘in situ’ assimilation were performed from February 1976 to November 1978. The onset, culmination, magnitude the spring bloom is described. dynamics phytoplankton highly governed by radiation. probably ended because lowered irradiance, due increased cell densities, a high degree mixing water column. with higher nutrient values than in more southerly areas. summer situation was comparable other areas ‘chemostat’-growth system. Grazing also an important factor regulating biomass during summer. Primary production estimates fjords coastal (100 gC/m3 per year) along Norwegian coast underestimated methods applied.
