Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging…
Historical atmospheric H2 levels were reconstructed using firn air measurements from two sites in Greenland (NEEM and Summit) and two sites in Antarctica (South Pole and Megadunes). A joint reconstruction based on the two Antarctic sites yields H2 levels monotonically increasing from about 330?
We examine global phylogeography of the two forms of giant petrel Macronectes spp. Although previously … considered to be a single taxon, and despite debate over the status of some populations and the … existence of minimal genetic data (one mitochondrial cytochrome b sequence per form)…
The efforts of Patterson and co-workers (Murozumi et al., 1969) to accurately measure Pb … concentrations in Greenland and Antarctic snow and ice produced the first reliable … determination of Pb pollution of the Earth’s polar ice sheets. Since then…
