Nitrogen uptake by phytoplankton and bacteria during an induced Phaeocystis pouchetii bloom, measured using size fractionation and flow cytometric sorting Open
Uptake of inorganic and organic nitrogen (N) by phytoplankton and bacteria was investigated during a mesocosm study conducted in Raunefjord, Norway in April 2005. One mesocosm was fertilized with nitrate and phosphate at a ratio of 16:1 an…

Phytoplankton and bacterial uptake of inorganic and organic nitrogen during an induced bloom of Phaeocystis pouchetii Open
A mesocosm experiment was conducted during the spring of 2003 in Raunefjord, west Norway. Inorganic nutrients (16 mu mol 1(-1) nitrate, 1 mu mol 1(-1) phosphate) were added to 2 enclosures with 10% of those concentrations (1.6 mu mol 1(-1)…

Plankton development and trophic transfer in seawater enclosures with nutrients and Phaeocystis pouchetii added Open
In high latitude planktonic ecosystems where the prymnesiophyte alga Phaeocystis pouchetii is often the dominant primary producer, its importance in structuring planktonic food webs is well known. In this study we investigated how the base…

Impact of microzooplankton on the progression and fate of the spring bloom in fjords of northern Norway Open
The objective of the study was to determine the role of microzooplankton in the fate of primary production and progression of the spring phytoplankton bloom in high latitude fjords. The 3 fjords, Balsfjord, Malangen and Ullsfjord (Norway),…

On assessment of prey ingestion by copepods Open
The consumption of photosynthetic and heterotrophic cells by an abundant calanoid copepod species feeding on natural plankton communities was quantified with a state-of-the-art image-analysis system. Late copepodid stages of Eucalanus pile…

The impact of proto- and metazooplankton on the fate of organic carbon in continental ocean margins. Final progress report, May 1992--July 1995 Open
Three fates potentially consume primary production occurring on ocean margins: portions can be oxidized within the water column, portions can sediment to shelf/slope depots, and portions can be exported to the interior ocean. Zooplankton m…
Ocean Margins Programs, Phase I research summaries Open
During FY 1992, the DOE restructured its regional coastal-ocean programs into a new Ocean Margins Program (OMP), to: Quantify the ecological and biogeochemical processes and mechanisms that affect the cycling, flux, and storage of carbon a…
