The impact of changes in sea ice advance on the large winter warming on the western Antarctic Peninsula
Read more of: The impact of changes in sea ice advance on the large winter warming on the western Antarctic PeninsulaOver 1979–2007 near-surface air temperatures on the maritime western side of the Antarctic Peninsula have increased throughout the year, with the greatest monthly temperature rise of 1.7 °C dec−1 occurring […]

Use of radium isotopes to estimate mixing rates and trace sediment inputs to surface waters in northern Marguerite Bay, Antarctic Peninsula
Read more of: Use of radium isotopes to estimate mixing rates and trace sediment inputs to surface waters in northern Marguerite Bay, Antarctic PeninsulaIn the western Antarctic Peninsula region, micronutrient injection facilitates strong plankton blooms that support productive food webs, unlike large areas of the low-productivity Southern Ocean.We use naturally occurring radioisotopes of […]

Hydrogen peroxide and ecdysone in the cryoprotective dehydration strategy of Megaphorura Arctica(Onychiuridae: Collembola)
Read more of: Hydrogen peroxide and ecdysone in the cryoprotective dehydration strategy of Megaphorura Arctica(Onychiuridae: Collembola)The Arctic springtail, Megaphorura arctica, survives sub-zero temperatures in a dehydrated state via trehalose-dependent cryoprotective dehydration. Regulation of trehalose biosynthesis is complex; based in part on studies in yeast and […]

Eemian interglacial reconstructed from a Greenland folded ice core
Read more of: Eemian interglacial reconstructed from a Greenland folded ice coreEfforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland […]

Comparison of methods for determining key marine areas from tracking data
Read more of: Comparison of methods for determining key marine areas from tracking dataThere is an urgent need to identify key marine areas for conservation, particularly in the high seas. A range of techniques have been applied to tracking data from higher predators, […]

The non-native chironomid Eretmoptera murphyi in Antarctica: erosion of the barriers to invasion
Read more of: The non-native chironomid Eretmoptera murphyi in Antarctica: erosion of the barriers to invasionAntarctica is the continent least affected by invasive species, but climate change and increasing human activity are increasing this threat. Antarctic terrestrial ecosystems generally have low biodiversity with simple community […]

Multiple-colony winter habitat use by murres Uria spp. in the Northwest Atlantic Ocean: implications for marine risk assessment
Read more of: Multiple-colony winter habitat use by murres Uria spp. in the Northwest Atlantic Ocean: implications for marine risk assessmentLimited knowledge of year-round seabird distributions hinders efforts to assess consequences of anthropogenic threats and climate-induced changes in the marine environment. In particular, there is urgent need to understand how […]

Shifting baselines in Antarctic ecosystems; ecophysiological response to warming in Lissarca miliaris at Signy Island, Antarctica
Read more of: Shifting baselines in Antarctic ecosystems; ecophysiological response to warming in Lissarca miliaris at Signy Island, AntarcticaThe Antarctic Peninsula has experienced a rapid increase in atmospheric temperature over the last 50 years. Whether or not marine organisms thriving in this cold stenothermal environment are able to […]

Scaling down the analysis of seabird-fishery interactions
Read more of: Scaling down the analysis of seabird-fishery interactionsSeabird-fishery interactions are currently a major issue in marine conservation management. A common approach to quantifying the extent of interactions is to overlay density maps of seabird and fishing activities […]

Antarctic ozone loss in 1979-2010: first sign of ozone recovery
Read more of: Antarctic ozone loss in 1979-2010: first sign of ozone recoveryA long-term ozone loss time series is necessary to understand the evolution of ozone in Antarctica. Therefore, we construct the time series using ground-based, satellite and bias-corrected multi-sensor reanalysis (MSR) […]
