Diversity of retrievable heterotrophic bacteria in Kongsfjorden, an Arctic fjord
The diversity and abundance of retrievable pelagic heterotrophic bacteria in Kongsfjorden, an Arctic fjord, was studied during the summer of 2011 (June, August, and September). Retrievable bacterial load ranged from 103 to 107CFUL-1 in June, while it was 104-106CFUL-1 in August and September. Based on 16S rRNA gene sequence similarities, a higher number of phylotypes was observed during August ...
متن کاملEvidence of Anomalously Low δ13C of Marine Organic Matter in an Arctic Fjord
Accurate estimation of relative carbon deposition (marine vs. terrestrial) is required for understanding the global carbon budget, particularly in the Arctic region, which holds disproportionate importance with respect to global carbon cycling. Although the sedimentary organic matter (SOM) concentration and its isotopic composition are important tools for such calculations, uncertainties loom o...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولRapid early Holocene retreat of a Laurentide outlet glacier through an Arctic fjord
Ice-sheet behaviour is disproportionately controlled by the dynamics of outlet glaciers that terminate in the ocean1,2. However, outlet-glacier dynamics—particularly over timescales longer than the observational record—are not well understood3, leading to uncertainties in our models of ice-sheet response to climate change. Here we use 10Be exposure ages and radiocarbon dating from the Sam Ford ...
متن کاملPelagic community production and carbon-nutrient stoichiometry under variable ocean acidification in an Arctic fjord
Net community production (NCP) and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June–July 2010. Nutrient depleted fjord water with natural plankton assemblages, enclosed in nine mesocosms of ∼ 50 m3 in volume, was exposed to pCO2 levels ranging initially from 185 to 1420 μatm. NCP estimati...
