Changes in firn properties affect the shape of pulse-limited radar altimeter echoes acquired over the polar ice sheets. We apply a waveform deconvolution model to CryoSat-2 low-resolution mode echoes to […]
Between 2014 and 2016 the annual mean total extent of Antarctic sea ice decreased by a record, unprecedented amount of 1.6 3 106 km2, the largest in a record starting […]
The Southern Ocean is disproportionately important in its effect on the Earth system, impacting climatic, biogeochemical and ecological systems, which makes recent observed changes to this system cause for global […]
Heavy metal variations in polar ice cores may reflect changes in global airborne pollution1. Reported profiles from Antarctica1–3 and Greenland4, where sampling resolution was normally larger than a year, have […]
The Earth’s plasmapause is a source of natural radio emission in the myriametric wavelength range (λvac∼10 km) and several mechanisms have been proposed for its generation. One such theory advocates […]
We infer that the Trinity Peninsula Group of the Antarctic Peninsula was deposited in a fore-arc basin(s) of composite type located between the Gondwanian arc massif (consisting of plutonic and […]
In an earlier paper (Green and Hamilton, J. atmos. terr. Phys.40, 1223, 1978), we reported on a preliminary analysis of six months’ magnetic data from the conjugate stations St. Anthony […]
