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 […]

Modeling the wave power distribution and characterisitics of plamaspheric hiss
Read more of: Modeling the wave power distribution and characterisitics of plamaspheric hissWe simulate the spatial and spectral distributions of plasmaspheric hiss using a technique that involves extensive ray tracing. The rays are injected in the equatorial chorus source region outside the […]

In-situ quantification of ice rheology and direct measurement of the Raymond Effect at Summit, Greenland using a phase-sensitive radar
Read more of: In-situ quantification of ice rheology and direct measurement of the Raymond Effect at Summit, Greenland using a phase-sensitive radarThe Glen exponent ncharacterizes the stress-dependence of ice deformation, directly influencing the rate at which ice masses respond to external forcing. The slow deformation in large ice-sheets makes laboratory rheometry […]

The discovery of new deep-sea hydrothermal vent communities in the Southern Ocean and implications for biogeography
Read more of: The discovery of new deep-sea hydrothermal vent communities in the Southern Ocean and implications for biogeographySince the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977, numerous vent sites and endemic faunal assemblages have been found along mid-ocean ridges and back-arc basins […]

Global seabird response to forage fish depletion – one-third for the birds
Read more of: Global seabird response to forage fish depletion – one-third for the birdsDetermining the form of key predator-prey relationships is critical for understanding marine ecosystem dynamics. Using a comprehensive global database, we quantified the effect of fluctuations in food abundance on seabird […]

Phytoplankton phenology in the global ocean
Read more of: Phytoplankton phenology in the global oceanIn recent years, phytoplankton phenology has been proposed as an indicator to monitor systematically the state of the pelagic ecosystem and to detect changes triggered by perturbation of the environmental […]
