Contrasting state-dependent effects of natural forcing on global and local climate variability
Read more of: Contrasting state-dependent effects of natural forcing on global and local climate variabilityNatural forcing from solar and volcanic activity contributes significantly to climate variability. The post-eruption cooling of strong volcanic eruptions was hypothesized to have led to millennial-scale variability during Glacials. Cooling […]

Understanding monsoon controls on the energy and mass balance of glaciers in the Central and Eastern Himalaya
Read more of: Understanding monsoon controls on the energy and mass balance of glaciers in the Central and Eastern HimalayaThe Indian and East Asian summer monsoons shape the melt and accumulation patterns of glaciers in High Mountain Asia in complex ways due to the interaction of persistent cloud cover, […]

Polarimetric radar reveals the spatial distribution of ice fabric at domes and divides in East Antarctica
Read more of: Polarimetric radar reveals the spatial distribution of ice fabric at domes and divides in East AntarcticaIce crystals are mechanically and dielectrically anisotropic. They progressively align under cumulative deformation, forming an ice-crystal-orientation fabric that, in turn, impacts ice deformation. However, almost all the observations of ice […]

Antimicrobial resistance in Antarctica: is it still a pristine environment?
Read more of: Antimicrobial resistance in Antarctica: is it still a pristine environment?Although the rapid spread of antimicrobial resistance (AMR), particularly in relation to clinical settings, is causing concern in many regions of the globe, remote, extreme environments, such as Antarctica, are […]

A late glacial-Holocene record of Southern Hemisphere westerly wind dynamics from the Falkland Islands, South Atlantic
Read more of: A late glacial-Holocene record of Southern Hemisphere westerly wind dynamics from the Falkland Islands, South AtlanticThe Southern Hemisphere westerly wind belt (SHWW) is a major feature of Southern Hemisphere, midlatitude climate that is closely linked with the sequestration and release of CO2 in the Southern […]

Fungal diversity in a sediment core from climate change impacted Boeckella Lake, Hope Bay, north-eastern Antarctic Peninsula assessed using metabarcoding
Read more of: Fungal diversity in a sediment core from climate change impacted Boeckella Lake, Hope Bay, north-eastern Antarctic Peninsula assessed using metabarcodingWe studied the fungal DNA present in a lake sediment core obtained from Trinity Peninsula, Hope Bay, north-eastern Antarctic Peninsula, using metabarcoding through high-throughput sequencing (HTS). Sequences obtained were assigned […]

Antarctic sea ice projections constrained by historical ice cover and future global temperature change
Read more of: Antarctic sea ice projections constrained by historical ice cover and future global temperature changeThere is low confidence in projections of Antarctic sea ice area (SIA), due to deficiencies in climate model sea ice processes. Ensemble regression techniques can help to reduce this uncertainty. […]

Disturbance ecology of the shallow Antarctic Benthos
Read more of: Disturbance ecology of the shallow Antarctic BenthosThe shallow Antarctic benthos (10 -100 m depth) are predicted to undergo drastic changes, particularly with respect to the iceberg scour disturbance regimes. With this is in mind, the field […]

Can current reanalyses accurately portray changes in Southern Annular Mode structure prior to 1979?
Read more of: Can current reanalyses accurately portray changes in Southern Annular Mode structure prior to 1979?Early reanalyses are less than optimal for investigating the regional effects of ozone depletion on Southern Hemisphere (SH) high-latitude climate because the availability of satellite sounder data from 1979 significantly […]

Do ditch‐side electric fences improve the breeding productivity of ground‐nesting waders?
Read more of: Do ditch‐side electric fences improve the breeding productivity of ground‐nesting waders?1. Insufficient reproduction as a consequence of predation on eggs and chicks is a major determinant of population decline in ground-nesting birds, including waders. For many populations, there is an […]
