Body and blubber relationships in antarctic pack ice seals: implications for blubber depth patterns.
Morphometrics and blubber depths from all four high Antarctic seals (Weddell, Ross, crabeater, and leopard) were obtained during a midsummer research cruise in the Ross Sea as the physiological ecology component of the U.S. Antarctic Pack Ice Seals project. These data are the only in vivo measurements of all four species from the same location and time of year and focused on variances in morpho...
متن کاملDiversity and structure of bacterial communities in Arctic versus Antarctic pack ice.
A comprehensive assessment of bacterial diversity and community composition in arctic and antarctic pack ice was conducted through cultivation and cultivation-independent molecular techniques. We sequenced 16S rRNA genes from 115 and 87 pure cultures of bacteria isolated from arctic and antarctic pack ice, respectively. Most of the 33 arctic phylotypes were >97% identical to previously describe...
متن کاملAntarctic Sea Ice: Physical Processes, Interactions and Variability
As sea ice formation plays a key role in driving Antarctic Bottom Water (AABW) production through brine rejection and the associated production of High Salinity freezing point Shelf Water 0tSSW), a possible link between interannual variability of the ice cover and changes in AABW production is expected. Analysis of satellite data indicates that the summer minimum extents (and area) in the Wedde...
متن کاملResponses of Antarctic pack-ice seals to environmental change and increasingkrill fishing
The compound effects of changing habitats, ecosystem interactions, and fishing practices have implications for the management of Antarctic krill and conservation of its predators. For Antarctic pack-ice seals, an important group of krill predators, we estimate the density and krill consumption in theWest Antarctic Peninsula (WAP)–WesternWeddell Sea area, the main fishery region; and we consider...
