Summertime cloud phase strongly influences surface melting on the Larsen C ice shelf, Antarctica
Read more of: Summertime cloud phase strongly influences surface melting on the Larsen C ice shelf, AntarcticaSurface melting on Antarctic Peninsula ice shelves can influence ice shelf mass balance, and consequently sea level rise. We show that summertime cloud phase on the Larsen C ice shelf […]

Effects of elevational range shift on the morphology and physiology of a carabid beetle invading the sub-Antarctic Kerguelen Islands.
Read more of: Effects of elevational range shift on the morphology and physiology of a carabid beetle invading the sub-Antarctic Kerguelen Islands.Climatic changes can induce geographic expansion and altitudinal shifts in the distribution of invasive species by offering more thermally suitable habitats. At the remote sub-Antarctic Kerguelen Islands, the predatory insect […]

Projecting ozone hole recovery using an ensemble of chemistry-climate models weighted by model performance and independence
Read more of: Projecting ozone hole recovery using an ensemble of chemistry-climate models weighted by model performance and independenceThe current method for averaging model ensembles, which is to calculate a multi model mean, assumes model independence and equal model skill. Sharing of model components amongst families of models […]

Tracer measurements in growing sea ice support convective gravity drainage parameterisations
Read more of: Tracer measurements in growing sea ice support convective gravity drainage parameterisationsGravity drainage is the dominant process redistributing solutes in growing sea ice. Modelling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice. We evaluate seven […]

Coordinated Observations of 8‐ and 6‐hr Tides in the Mesosphere and Lower Thermosphere by Three Meteor Radars Near 60°S Latitude
Read more of: Coordinated Observations of 8‐ and 6‐hr Tides in the Mesosphere and Lower Thermosphere by Three Meteor Radars Near 60°S LatitudeAtmospheric 8‐ and 6‐hr tides are observed for the first time in the zonal and meridional winds at ~82–97 km altitudes simultaneously at Tierra del Fuego (TDF; 53.7°S, 67.7°W), King […]

Using the aa index over the last 14 solar cycles to characterize extreme geomagnetic activity
Read more of: Using the aa index over the last 14 solar cycles to characterize extreme geomagnetic activityGeomagnetic indices are routinely used to characterize space weather event intensity. The DST index is well resolved, but is only available over 5 solar cycles. The aa index extends over […]

Invasive marine species discovered on non–native kelp rafts in the warmest Antarctic island.
Read more of: Invasive marine species discovered on non–native kelp rafts in the warmest Antarctic island.Antarctic shallow coastal marine communities were long thought to be isolated from their nearest neighbours by hundreds of kilometres of deep ocean and the Antarctic Circumpolar Current. The discovery of […]

The growth and reproduction of Antarctic flowering plants
Read more of: The growth and reproduction of Antarctic flowering plantsThe presence of flowering plants within the Antarctic botanical zone (as defined by Greene 1964 a) has been known for nearly 150 years. The first to be discovered was a […]
