Mapping the geometry of the ice sheet is fundamental to many advanced investigations, e.g., on ice dynamics, mass balance, ice – ocean interaction, ice – atmosphere interaction, and ice body […]
1. Lakes and ponds in the Larsemann Hills and Bolingen Islands (East-Antarctica) were characterised by cyanobacteria-dominated, benthic microbial mats. A 56-lake dataset representing the limnological diversity among the more than […]
The small size of the billions of migrating songbirds commuting between temperate breeding sites and the tropics has long prevented the study of the largest part of their annual cycle […]
Despite an increasing number of Antarctic soil diversity assessments, understanding of the bacterial community composition in the arid soil environments of the maritime/continental Antarctic transitional zone remains lacking. Most documented […]
It has been shown that in real food webs, the strongest omnivorous feedback, a three-link positive feedback, is a good indicator of system stability, suggesting that the strongest positive feedback […]
Establishing accurate chronologies for Late Quaternary Antarctic marine sediments is often a challenge due to variable radiocarbon reservoir effects, the presence of coarse-grained glacial material and a lack of carbonate […]
There is great concern currently over environmental change and the biotic responses, actual or potential, to that change. There is also great concern over biodiversity and the observed losses to […]
Amounts of source gases with stratospheric sinks (CFCs, N2O, CH4) are affected by changes in BrewerDobson circulation. Source gases and their degradation products are important for atmospheric chemistry and climate. […]
The northern wheatear (Oenanthe oenanthe) is a small (approx. 25 g), insectivorous migrant with one of the largest ranges of any songbird in the world, breeding from the eastern Canadian […]
New evidence from models, ozone measurements and balloon trajectories is presented that confirms the existence of a broad cohesive region of air at the edge of the Antarctic stratospheric vortex […]
Polar lakes respond quickly to climate-induced environmental changes. We studied the chemical limnological variability in 127 lakes and ponds from eight ice-free regions along the East Antarctic coastline, and compared […]
