A stochastic dynamical model of Arctic sea ice
The noise forcing underlying the variability in the Arctic ice cover has a wide range of principally unknown origins. For this reason, the analytical and numerical solutions of a stochastic […]

Moss survival through in situ cryptobiosis after six centuries of glacier burial
Read more of: Moss survival through in situ cryptobiosis after six centuries of glacier burialCryptobiosis is a reversible ametabolic state of life characterized by the ceasing of all metabolic processes, allowing survival of periods of intense adverse conditions. Here we show that 1) entire […]

Functional group diversity is key to Southern Ocean benthic carbon pathways
Read more of: Functional group diversity is key to Southern Ocean benthic carbon pathwaysHigh latitude benthos are globally important in terms of accumulation and storage of ocean carbon, and the feedback this is likely to have on regional warming. Understanding this ecosystem service […]

Future directions and priorities for Arctic bryophyte research
Read more of: Future directions and priorities for Arctic bryophyte researchThe development of evidence-based international strategies for the conservation and management of Arctic ecosystems in the face of climate change is hindered by critical knowledge gaps in Arctic floristic diversity […]

Polar zoobenthos blue carbon storage increases with sea ice losses, because across-shelf growth gains from longer algal blooms outweigh ice scour mortality in the shallows
Read more of: Polar zoobenthos blue carbon storage increases with sea ice losses, because across-shelf growth gains from longer algal blooms outweigh ice scour mortality in the shallowsOne of the major climate-forced global changes has been white to blue to green; losses of sea ice extent in time and space around Arctic and West Antarctic seas has […]

Unprecedented springtime retreat of Antarctic sea ice in 2016
Read more of: Unprecedented springtime retreat of Antarctic sea ice in 2016During Austral spring 2016 Antarctic sea ice extent (SIE) decreased at a record rate of 75 × 103 km2 day-1, which was 46% faster than the mean rate and 18% faster than in any […]

Contrasting drivers of reproductive ageing in albatrosses
Read more of: Contrasting drivers of reproductive ageing in albatrosses1. Age-related variation in reproductive performance is ubiquitous in wild vertebrate populations and has important consequences for population and evolutionary dynamics. 2. The ageing trajectory is shaped by both within-individual […]

Planococcus versutus sp. nov., isolated from soil
Read more of: Planococcus versutus sp. nov., isolated from soilA taxonomic study was performed on a novel Gram-stain-positive, coccus-shaped, orange-pigmented motile bacterium, designated as strain L10.15T. The organism was isolated from a soil sample collected in Lagoon Island (close […]

Holocene black carbon in Antarctica paralleled Southern Hemisphere climate
Read more of: Holocene black carbon in Antarctica paralleled Southern Hemisphere climateBlack carbon (BC) and other biomass-burning (BB) aerosols are critical components of climate forcing but quantification, predictive climate modeling, and policy decisions have been hampered by limited understanding of the […]

Stratospheric response to the 11-year solar cycle: Breaking planetary waves, internal reflection and resonance
Read more of: Stratospheric response to the 11-year solar cycle: Breaking planetary waves, internal reflection and resonanceBreaking planetary waves (BPWs) affect stratospheric dynamics by reshaping the waveguides, causing internal wave reflection and preconditioning sudden stratospheric warmings. This study examines observed changes in BPWs during the northern […]

The transient response of ice-shelf melting to ocean change
Read more of: The transient response of ice-shelf melting to ocean changeIdealised modelling studies have shown that the melting of ice shelves varies as a quadratic function of ocean temperature. However, this result is the equilibrium response, derived from steady ice— […]

Position and variability of complex structures in the central East Antarctic Ice Sheet
Read more of: Position and variability of complex structures in the central East Antarctic Ice SheetAlthough the flow of the East Antarctic Ice Sheet is well constrained from surface measurements and altimetry, our knowledge of the dynamic processes within the ice sheet remains limited. Recent […]
