Potential Ad´elie penguin Pygoscelis adeliae breeding habitat in the AustralianAntarctic Territory (AAT: 45◦E–136◦E, 142◦E–160◦E) was mapped using a geographic information system (GIS)…
The oxygen (O2) concentration in the surface ocean is influenced by biological and physical processes. With concurrent measurements of argon (Ar), which has similar solubility properties as oxygen…
Potential Adélie penguin breeding habitat (defined as ice-free land with area >4000 m2 and within 500 m of the ocean) in the Australian Antarctic Territory (AAT) was mapped using a GIS…
Recent time-series measurements of atmospheric O2 show that the land biosphere and world oceans annually sequestered 1.4 ± 0.8 and 2.0 ± 0.6 gigatons of carbon, respectively between mid-1991 and mid-1997. The rapid storage of carbon by the Land biosphere from 1991 to 1997 contrasts with the 1980s…
