Comparison of relativistic microburst activity seen by SAMPEX with ground-based wave measurements at Halley, Antarctica
Read more of: Comparison of relativistic microburst activity seen by SAMPEX with ground-based wave measurements at Halley, AntarcticaRelativistic electron microbursts are a known radiation belt particle precipitation phenomenon; however, experimental evidence of their drivers in space have just begun to be observed. Recent modeling efforts have shown […]

A year long comparison of GPS TEC and global ionosphere-thermosphere models
Read more of: A year long comparison of GPS TEC and global ionosphere-thermosphere modelsThe prevalence of GPS total electron content (TEC) observations has provided an opportunity for extensive global ionosphere‐thermosphere model validation efforts. This study presents a year‐long data‐model comparison using the Global […]

Atmospheric ice-nucleating particles in the dusty tropical Atlantic
Read more of: Atmospheric ice-nucleating particles in the dusty tropical AtlanticDesert dust is one of the most important atmospheric ice‐nucleating aerosol species around the globe. However, there have been very few measurements of ice‐nucleating particle (INP) concentrations in dusty air […]

Evidences of strong sources of DFe and DMn in Ryder Bay, Western Antarctic Peninsula
Read more of: Evidences of strong sources of DFe and DMn in Ryder Bay, Western Antarctic PeninsulaThe spatial distribution, biogeochemical cycling and external sources of dissolved iron and dissolved manganese (DFe and DMn) were investigated in Ryder Bay, a small coastal embayment of the West Antarctic […]

Diapycnal mixing in the Southern Ocean diagnosed using the DIMES tracer and realistic velocity fields
Read more of: Diapycnal mixing in the Southern Ocean diagnosed using the DIMES tracer and realistic velocity fieldsIn this work, we use realistic isopycnal velocities with a 3D eddy diffusivity to advect and diffuse a tracer in the Antarctic Circumpolar Current, beginning in the Southeast Pacific and […]

Hydrocarbons in the Antarctic marine environment
Read more of: Hydrocarbons in the Antarctic marine environmentThe Antarctic marine ecosystem contains low concentrations of a range of hydrocarbons, overwhelmingly biogenic in origin. The low natural levels of hydrocarbons and the small amount of local human activity […]

Physical Conditions of Fast Glacier Flow: 1. Measurements From Boreholes Drilled to the Bed of Store Glacier, West Greenland
Read more of: Physical Conditions of Fast Glacier Flow: 1. Measurements From Boreholes Drilled to the Bed of Store Glacier, West GreenlandMarine‐terminating outlet glaciers of the Greenland Ice Sheet make significant contributions to global sea level rise, yet the conditions that facilitate their fast flow remain poorly constrained owing to a […]
