Global environmental consequences of 21st century ice sheet melt
Read more of: Global environmental consequences of 21st century ice sheet meltGovernment policies currently commit us to surface warming of three to four degrees Celsius above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. Ice-sheet discharge was not […]

Propagation and vertical structure of the tidal flow in Nares Strait
Read more of: Propagation and vertical structure of the tidal flow in Nares StraitThe southward freshwater flux though Nares Strait is an important component of the Arctic’s freshwater budget. On short time scales, flow through the strait is dominated by the tides, and […]

Morphological and geological features of Drake Passage, Antarctica, from a new digital bathymetric model
Read more of: Morphological and geological features of Drake Passage, Antarctica, from a new digital bathymetric modelThe Drake Passage is an oceanic gateway of about 850 km width located between South America and the Antarctic Peninsula that connects the southeastern Pacific Ocean with the southwestern Atlantic Ocean.

Contrasting hydrological controls on bed properties during the acceleration of Pine Island Glacier, West Antarctica
Read more of: Contrasting hydrological controls on bed properties during the acceleration of Pine Island Glacier, West AntarcticaIn the Amundsen sector of West Antarctica, the flow of glaciers accelerates when intrusion of warm ocean water onto the continental shelf induces strong melting beneath ice shelves and thinning […]

Antarctic clouds, supercooled liquid water and mixed-phase investigated with DARDAR: geographical and seasonal variations
Read more of: Antarctic clouds, supercooled liquid water and mixed-phase investigated with DARDAR: geographical and seasonal variationsAntarctic tropospheric clouds are investigated using the radar-lidar DARDAR (raDAR/liDAR)-MASK products. The cloud fraction is divided into the supercooled liquid water (SLW)-containing clouds and the all-ice clouds. The low-level SLW […]

Predicting which species succeed in climate-forced polar seas
Read more of: Predicting which species succeed in climate-forced polar seasUnderstanding the mechanisms which determine the capacity of any species to adapt to changing environmental conditions is one of the foremost requirements in accurately predicting which populations, species and clades […]

Determination of the equatorial electron differential flux from observations at low Earth orbit
Read more of: Determination of the equatorial electron differential flux from observations at low Earth orbitVariations in the high-energy relativistic electron flux of the radiation belts depend on transport, acceleration, and loss processes, and importantly on the lower-energy seed population. However, data on the seed […]

Coming up short: Identifying substrate and geographic biases in fungal sequence databases
Read more of: Coming up short: Identifying substrate and geographic biases in fungal sequence databasesInsufficient reference database coverage is a widely recognized limitation of molecular ecology approaches which are reliant on database matches for assignment of function or identity. Here, we use data from […]

Holocene fire activity during low-natural flammability periods reveals scale-dependent cultural human-fire relationships in Europe
Read more of: Holocene fire activity during low-natural flammability periods reveals scale-dependent cultural human-fire relationships in EuropeFire is a natural component of global biogeochemical cycles and closely related to changes in human land use. Whereas climate-fuel relationships seem to drive both global and subcontinental fire regimes, […]

Divergent foraging strategies during incubation of an unusually wide-ranging seabird, the Murphy’s petrel
Read more of: Divergent foraging strategies during incubation of an unusually wide-ranging seabird, the Murphy’s petrelDivergent foraging strategies may emerge within a population due to a combination of physiological and environmental factors; yet to persist, neither strategy should offer a consistent selective advantage over the […]
