Variability and trends in sea ice extent and ice production in the Ross Sea
[1] Salt release during sea ice formation in the Ross Sea coastal regions is regarded as a primary forcing for the regional generation of Antarctic Bottom Water. Passive microwave data from November 1978 through 2008 are used to examine the detailed seasonal and interannual characteristics of the sea ice cover of the Ross Sea and the adjacent Bellingshausen and Amundsen seas. For this period th...
متن کاملAllometric scaling and taxonomic variation in nutrient utilization traits and maximum growth rate of phytoplankton
Nutrient utilization traits can be used to link the ecophysiology of phytoplankton to population dynamic models and the structure of communities across environmental gradients. Here we analyze a comprehensive literature compilation of four traits: maximum nutrient uptake rate; the half-saturation constant for nutrient uptake; the minimum subsistence quota, measured for nitrate and phosphate; an...
متن کاملInorganic Carbon Utilization by Ross Sea Phytoplankton across Natural and Experimental Co2 Gradients1
We present results from a field study of inorganic carbon (C) acquisition by Ross Sea phytoplankton during Phaeocystis-dominated early season blooms. Isotope disequilibrium experiments revealed that HCO3 ) was the primary inorganic C source for photosynthesis in all phytoplankton assemblages. From these experiments, we also derived relative enhancement factors for HCO3 ) ⁄CO2 interconversion as...
متن کاملSeasonal Production and Bacterial Utilization of Doc in the Ross Sea, Antarctica
Heterotrophic picoplankton, including Bacteria and Archaea, form a major, often dominant component of the euphotic zone biomass throughout much of the world ocean. In Antarctic waters however, the bacterial biomass is a much smaller fraction of the total plankton stock, at least during the Austral summer. In the Ross Sea during the 1996-1997 growing season, bacterial abundance reached a peak of...
