The Antarctic Peninsula is considered to be the last region of Antarctica to have been fully glaciated as a result of Cenozoic climatic cooling. As such, it was likely the last refugium for plants and animals that had inhabited the continent since it separated from the Gondwana supercontinent. Drill cores and seismic data acquired during two cruises(More)
INTRODUCTION A high-resolution aeromagnetic survey collected over the North Slope of Alaska by World Geoscience was acquired in response to a need for highly detailed data in an areawhere traditional geophysical techniques are expensive and prohibitive (McConnell, 1995) (Figure 1). These data were recently released to the University of Texas’ Institute for(More)
COMMENTARY Correction for “Transcription factor RBPJ/CSL: A genome-wide look at transcriptional regulation,” by Lucio Miele, which appeared in issue 36, September 6, 2011, of Proc Natl Acad Sci USA (108:14715–14716; first published August 24, 2011; 10.1073/ pnas.1110570108). The authors note that, due to a printer’s error, on page 14715, middle column,(More)
Volcanic sills and dikes inferred from seismic reflection profiles and geophysical studies of the Ross Sea are thought to be related to the rift basins in the region, and their emplacement to be coeval with extension. However, lack of precise geochronology in the Terror Rift of the Ross Sea region has left these inferred relationships poorly constrained and(More)
