Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom
[1] Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses a critical threshold but rather occurs...
متن کاملHeterotrophic Nanoflagellate, Paraphysomonas imperforata
Two different psychrophilic types of the heterotrophic nanoflagellate Paraphysomonas imperforata were isolated from Newfoundland coastal waters and the Arctic Ocean. When fed bacteria without food limitation, both isolates were able to grow at temperatures from -1.8 to 20°C, with maximum growth rates of 3.28 day-' at 15°C and 2.28 day-l at 12.3°C for the Newfoundland and the Arctic isolates, re...
متن کاملCoccolithophore bloom size variation in response to the regional environment of the subarctic North Atlantic
Several environmental/physical variables derived from satellite and in situ data sets were used to understand the variability of coccolithophore abundance in the subarctic North Atlantic. The 7-yr (1997–2004) time-series analysis showed that the combined effects of high solar radiation, shallow mixed layer depth (,20 m), and increased temperatures explained .89% of the coccolithophore variation...
متن کاملBio-optical and physical variability in the subarctic North Atlantic Ocean during the spring of 1989
A unique set of physical, bio-optical, and meteorological observations were made from a mooring located in the open ocean south of Iceland (59o29.5 ' N, 20ø49.8' W) from April 13 to June 12, 1989. The present measurements are apparently the first to resolve the rapid transition to springtime physical and biological conditions at such a high latitude site. Our data were collected with bio-optica...
متن کاملEffects of increased pCO2 and temperature on the North Atlantic spring bloom. III. Dimethylsulfoniopropionate
The CLAW hypothesis argues that a negative feedback mechanism involving phytoplankton-derived dimethylsulfoniopropionate (DMSP) could mitigate increasing sea surface temperatures that result from global warming. DMSP is converted to the climatically active dimethylsulfide (DMS), which is transferred to the atmosphere and photochemically oxidized to sulfate aerosols, leading to increases in plan...
