The Scotia Sea has been a focus of biological- and physical oceanographic study since the Discovery expeditions in the early 1900s. It is a physically energetic region with some of […]
The acoustic impedance of the subglacial material beneath 7.2 km profiles on four ice streams in Antarctica has been measured using a seismic technique. The ice streams span a wide […]
The Intergovernmental Panel on Climate Change (IPCC) confirmed that mean global warming was 0.6 +/- 0.2degreesC during the 20th century and cited anthropogenic increases in greenhouse gases as the likely […]
A major new synthesis of ophiolite geochronology and map of global Phanerozoic distribution indicates that previously noted pulses of ophiolite obduction can be linked to superplume-related tectonism. A marked cyclicity […]
Contemporary studies of long-term changes in the ionosphere stem mostly from the suggestions by Roble and Dickinson [1989] that “global warming” in the lower atmosphere is accompanied by “global cooling” […]
Quasi-monthly samples of the Antarctic pectinid bivalve Adamussium colbecki were examined to determine the gametogenic pattern and periodicity. Both female and male gametogenic patterns show a very distinct seasonal development, […]
