During the transition from the Last Glacial Maximum (LGM) to the Holocene, the atmospheric N2O mole fraction increased by 80 nmol mol?1. Using ice core measurements of N2O isotopomer ratios, we show that this increase was driven by increases in both nitrification and denitrification…

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…
Beaufort Island, Ross Sea, Antarctica, is a Specially Protected Area originally designated on account of, and still supporting, a small winter sea ice breeding colony of Emperor penguins, a large summer breeding colony of Adélie penguins, and several colonies of Skuas. A substantial area of moss…
