Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, […] The post Sensitivity of the Bootstrap sea ice concentration algorithm to surface parameters in the Antarctic marginal ice zone using passive microwave retrievals appeared first on British…
Climate change is driving vegetation expansion in polar regions. Roland et al.1 report a 14-fold greening trend across the Antarctic Peninsula region since the 1980s, based on satellite data. However, […] The post Greening rates are sensitive to methodology and biology; comment to Sustained greening of the Antarctic Peninsula observed from satellites [Commentary] appeared first on British…
Climate‐driven alterations in sea‐ice dynamics and shifting fishing activity are reshaping ecosystems across the Arctic and Antarctic, yet conservation‐relevant information for chondrichthyans (sharks, rays, and chimaeras) remains limited. We present […] The post Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters appeared first on British Antarctic Survey .
Understanding the demography of animal populations is fundamental to conservation biology. Key parameters such as sex ratio and reproductive success are important contributors for assessing current population health, forecasting population […] The post Sex ratio, pregnancy status and blubber testosterone concentrations of humpback whales (Megaptera novaeangliae) on foraging grounds in the…
Strongly pagophilic, the Adélie penguin Pygoscelis adeliae has long been designated a sea ice obligate species, which included the requirement to find pack ice on which to molt. However, observations […] The post Pagophilic rather than sea ice obligate: effects of sea ice and colony size on Adélie penguin molt location appeared first on British Antarctic Survey .
During Pleistocene ice ages, abrupt climate changes co-occurred with switches in Atlantic Meridional Overturning Circulation (AMOC) strength. The global impact and characteristic north-south temperature pattern of these events is typically […] The post Planetary energy budget during abrupt glacial climate events set by Atlantic Ocean heat valve appeared first on British Antarctic Survey .
The footprint and cumulative impact of national governmental programme and tourist activities is increasing at marine and terrestrial sites across Antarctica. Associated impacts on species and ecosystems include habitat degradation, […] The post The Antarctic Specially Managed Area (ASMA) spatial management tool: an underused solution to Antarctica’s increasing environmental challenges appeared…
The AMPLIFY-EDS project, funded under UKRI’s Digital Research Infrastructure (DRI) programme, aimed to advance the Environmental Data Service (EDS) towards a federated, user-centred model by developing standardised, trusted workflows for […] The post From observation to insight: developing standardised and trusted environmental data services appeared first on British Antarctic Survey .
Wildfires are becoming increasingly frequent and intense under ongoing climate change, with the potential to emit and transport particles, from black carbon to nutrient-bearing aerosols, into remote and fragile ecosystems […] The post Arctic transport of North American and Canadian wildfire aerosols appeared first on British Antarctic Survey .
Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry-derived sea-ice thickness. Here we use the post-2022 CRYO2ICE configuration to derive […] The post Robust Regional Contrast but Penetration‐Sensitive Snow Thickness Over Sea Ice From Multi‐Winter Antarctic CRYO2ICE Observations appeared first on British Antarctic…
