Seasonal and diurnal dependences of Pc3 and Pc4 geomagnetic pulsation power at very high latitudes
Read more of: Seasonal and diurnal dependences of Pc3 and Pc4 geomagnetic pulsation power at very high latitudesIntroduction In our studies [Chugunova et al., 2002,03,04] we found the occurrence of ULF waves in the nominal Рс3-4 band in the polar cap. About 15% of this ULF activity […]

Distribution and mineralogy of carbonate sediments on Antarctic shelves
Read more of: Distribution and mineralogy of carbonate sediments on Antarctic shelvesWe analyzed 214 new core-top samples for their CaCO3 content from shelves all around Antarctica in order to understand their distribution and contribution to the marine carbon cycle. The distribution […]

Determining the native/non-native status of newly discovered terrestrial and freshwater species in Antarctica – current knowledge, methodology and management action
Read more of: Determining the native/non-native status of newly discovered terrestrial and freshwater species in Antarctica – current knowledge, methodology and management actionContinental Antarctic terrestrial and freshwater environments currently have few established non-native species compared to the sub-Antarctic islands and other terrestrial ecosystems on Earth. This is due to a unique combination […]

Testing for flow in the north polar layered deposits of Mars using radar stratigraphy and a simple 3D ice-flow model
Read more of: Testing for flow in the north polar layered deposits of Mars using radar stratigraphy and a simple 3D ice-flow modelThe water-ice-rich north polar layered deposits (NPLD) of Mars play a key role in the Martian climate through an active exchange of water vapor with the atmosphere. Conditions are not […]

Persistent circulation regimes and preferred regime transitions in the North Atlantic
Read more of: Persistent circulation regimes and preferred regime transitions in the North AtlanticThe persistent regime behavior of the eddy-driven jet stream over the North Atlantic is investigated. The North Atlantic jet stream variability is characterized by the latitude of the maximumlower tropospheric […]

Geological constraints on glacio-isostatic adjustment models of relative sea-level change during deglaciation of Prince Gustav Channel, Antarctic Peninsula
Read more of: Geological constraints on glacio-isostatic adjustment models of relative sea-level change during deglaciation of Prince Gustav Channel, Antarctic PeninsulaThe recent disintegration of Antarctic Peninsula ice shelves, and the associated accelerated discharge and retreat of continental glaciers, has highlighted the necessity of quantifying the current rate of Antarctic ice […]

Functional Programming through Deep Time: Modeling the first complex ecosystems on Earth. Experience Report
Read more of: Functional Programming through Deep Time: Modeling the first complex ecosystems on Earth. Experience ReportThe ecology of Earth’s first large organisms is an unsolved problem in palaeontology. This experience report discusses the determination of which ecosystems could have been feasible, by considering the biological […]
