Firn on ice sheets
Most of the Greenland and Antarctic ice sheets are covered with firn — the transitional material between snow and glacial ice. Firn is vital for understanding ice-sheet mass balance and […]

Quantifying zoobenthic blue carbon storage across habitats within the Arctic’s Barents Sea
Read more of: Quantifying zoobenthic blue carbon storage across habitats within the Arctic’s Barents SeaIntroduction: The Arctic sea ice extent in September (when it is at its lowest) has declined 13% Q10 per decade, and the Arctic Ocean is becoming a more Atlantic-influenced system. […]

How precisely can we map blue ice in Antarctica?
Read more of: How precisely can we map blue ice in Antarctica?Precise mapping of Blue Ice Regions (BIRs) in Antarctica can facilitate resource management during expeditions and help plan field investigations. Satellite-based BIR mapping was traditionally performed with large-swath, coarse to […]

12 years of continuous atmospheric O2, CO2 and APO data from Weybourne Atmospheric Observatory in the United Kingdom
Read more of: 12 years of continuous atmospheric O2, CO2 and APO data from Weybourne Atmospheric Observatory in the United KingdomWe present a 12-year time series of continuous atmospheric measurements of O2 and CO2 at the Weybourne Atmospheric Observatory in the United Kingdom. These measurements are combined into the term […]

Locating subglacial sediments across West Antarctica with isostatic gravity anomalies
Read more of: Locating subglacial sediments across West Antarctica with isostatic gravity anomaliesSubglacial sediments are an important control on fast flowing ice in West Antarctica but their spatial distribution over catchment-wide areas is still largely unknown. Previously, airborne gravity anomalies could not […]

Four unreported emperor penguin colonies discovered by satellite
Read more of: Four unreported emperor penguin colonies discovered by satellitePredictions of the future emperor penguins population, linked to anthropogenic climate change, are stark. Current models suggest that if CO2 emissions continue to rise at present rates, almost all colonies […]

Biogeographic survey of soil bacterial communities across Antarctica
Read more of: Biogeographic survey of soil bacterial communities across AntarcticaAntarctica and its unique biodiversity are increasingly at risk from the effects of global climate change and other human influences. A significant recent element underpinning strategies for Antarctic conservation has […]

Future Antarctic Climate: Storylines of mid-latitude jet strengthening and shift emergent from CMIP6
Read more of: Future Antarctic Climate: Storylines of mid-latitude jet strengthening and shift emergent from CMIP6A main source of regional climate change uncertainty is the large disparity across models in simulating the atmospheric circulation response to global warming. Using the latest suite of global climate […]

Inorganic geochemistry of lake sediments: A review of analytical techniques and guidelines for data interpretation
Read more of: Inorganic geochemistry of lake sediments: A review of analytical techniques and guidelines for data interpretationInorganic geochemistry is a powerful tool in paleolimnology. It has become one of the most commonly used techniques to analyze lake sediments, particularly due to the development and increasing availability […]

Diesel−biodegradation and biosurfactant−production by Janthinobacterium lividum AQ5-29 and Pseudomonas fildesensis AQ5-41 isolated from Antarctic soil
Read more of: Diesel−biodegradation and biosurfactant−production by Janthinobacterium lividum AQ5-29 and Pseudomonas fildesensis AQ5-41 isolated from Antarctic soilGiven the substantial diesel demand in Antarctic operations, the means of addressing ecological restoration following its inappropriate release are attracting attention from researchers. The Madrid Protocol mandates the use of […]
