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…

Using high-precision ice core measurements of CO2, ?13C-CO2, CH4, and N2O, this study provides carbon isotope constraints on a sizeable, centennial-scale CO2 jump at the onset of Marine Isotope Stage 9 (MIS 9). The very end of the Heinrich stadial (HS) characterizing Termination IV (T-IV, ca.
A brief review of key ice core research in Greenland and Antarctica
A review of ice core atmospheric nitrous oxide reconstructions including concentrations and stable isotope ratios (N and O).
Understanding the causes of past atmospheric methane (CH4) variability is important for characterizing the relationship between CH4, global climate and terrestrial biogeochemical cycling.
The Southern Hemisphere Imaging Riometer Experiment (SHIRE) is a phased array of radio receivers that observes the Antarctic sky at 38 MHz. It detects ionospheric absorption of cosmic radio noise near an altitude of 90km and is used to study the aurora and other high-latitude ionospheric phenomena.
The Antarctic-Arctic Radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortium … (AARDDVARK) provides a network of continuous long-range observations of the lower ionosphere in the … polar regions.
