Estimating the Barents Sea polar bear subpopulation size
A large-scale survey was conducted in August 2004 to estimate the size of the Barents Sea polar bear subpopulation. We combined helicopter line transect distance sampling (DS) surveys in most of the survey area with total counts in small areas not suitable for DS. Due to weather constraints we failed to survey some of the areas originally planned to be covered by DS. For those, abundance was es...
متن کاملThe Barents Sea
Fisheries in the North Atlantic, southeast Atlantic, and eastern central Atlantic reached their maximum production levels one or two decades ago and are now showing a declining trend in total catches (1). The declining catches are consistent with observations that these areas have the highest incidence of overexploited stocks, depleted stocks or slowly recovering stocks that have been depleted ...
متن کامل“Flashes” of Chlorophyll-a Concentration Derived from in Situ and Remote Sensing Data at the Polar Front in the Barents Sea
The Polar Front Zone (PFZ) in the Barents Sea is an area where warm, salty water of the North Atlantic (AtW) interacts with cold, less dense, Arctic water (ArW) and the fresher water produced by melting ice (MW). In the spring a large-scale transformation of the structure of the PFZ is accompanied by the development of mesoscale eddies with characteristic sizes of 25 to 40 km. The vertical velo...
متن کاملBarents Sea multidecadal variability
[1] We present area-averaged time series of temperature for the 100–150 m depth layer of the Barents Sea from 1900 through 2006. This record is dominated by multidecadal variability on the order of 4 C which is correlated with the Atlantic Multidecadal Oscillation Index. Citation: Levitus, S., G. Matishov, D. Seidov, and I. Smolyar (2009), Barents Sea multidecadal variability, Geophys. Res. Let...
متن کاملDiversity of free-living prokaryotes from a deep-sea site at the Antarctic Polar Front.
To contribute to the understanding of deep-sea planktonic communities, we explored the prokaryotic diversity of a 3000 m deep site at the Antarctic Polar Front using molecular methods. Bacterial 16S rDNA-amplified sequences corresponded to the as yet uncultivated groups SAR11, within the alpha-Proteobacteria, and SAR324, within the delta-Proteobacteria, as well as to the gamma-Proteobacteria, C...
