A baseline for persistent organohalogen compound (POC) accumulation in the Antarctic … keystone species, Antarctic krill (Euphausia superba) has been established for a 50¡ã longitudinal … range of the eastern Antarctic sector. Samples of adult krill…
Ice core records from Antarctic and Greenland have revealed that the last deglaciation (ca. 19,000 to 11,000 years before present) was accompanied by a ca. 80 ppmv increase in atmospheric CO2 and a sequence of large, hemispheric climate variations.
Changes in solar activity modulate the galactic cosmic ray flux, and in turn, the production rate of cosmogenic 10Be in the Earth’s atmosphere. The best archives of past changes in 10Be production rate are polar ice cores.
Ice core records from Antarctic and Greenland have revealed that the last deglaciation (ca. 19, 000 to 11, 000 years before present) was accompanied by an 80 ppmv increase in atmospheric CO2 and a sequence of large, hemispheric climate variations.
During the transition from the last glacial maximum to the present warm interglacial a sequence of large, hemispheric, climate changes took place: the Bølling‐Allerød and Younger … Dryas in the north and the Antarctic Cold Reversal in the south.
Special emphasis should be placed on determining optimal sampling regimes to detect … statistically significant differences in key indicators between populations for species with high conservation … values, especially when invasive handling techniques are the only method of gathering … data.
Reconstructing and modeling extent and dynamics of ice sheets is crucial in … understanding and predicting the evolution of ice sheets. Key to ice sheet dynamics are ice … streams, which drain most of the ice from the ice sheet interior to the ice shelves, where most of … the ice is lost.
Euphausiids are vital components of many oceanic foodwebs. Due to their large size, they are key prey … species for many vertebrates, and several species are subject to commercial fisheries. The best studied … euphausiid species is Antarctic krill (Euphausia superba)…
