1. 2008 South Pole Firn Air Methane Isotopes [sowers_0739491]
This project will involve the measurement of methane and other trace gases in firn air collected at South Pole, Antarctica. The analyses will include: methane isotopes, light non-methane hydrocarbons ...


2. Collaborative Research: Constructing an Ultra-high Resolution Atmospheric Methane Record for the Last 140,000 Years from WAIS Divide Core [Sowers_0538538]
This award supports a project to develop a high-resolution (every 50 yr) methane data set.


3. Constructing an isotopic record of atmospheric methane and nitrous oxide over the last century from South Pole firn air [Sowers_0125981]
Over the last 150 years, atmospheric CH4 and N2O concentrations have risen in response to increased emissions from various anthropogenic activities. As this trend is liable to continue ...


4. Constructing the first D/H record of atmospheric methane covering the last two centuries [Sowers_0125900]
Over the last 200 years, the atmospheric CH4 burden has doubled in response to increased emissions from various anthropogenic activities. As this trend is liable to continue in the foreseeable ...


5. Elemental and isotopic composition of trapped gases in the horizontal Moulton ice core [Moulton_Gas_Data]
Data are included for the elemental and isotopic composition of trapped gases in the A, E and F trenches. Specifically, the d15N of N2, d18O of atm O2, dO2/N2, dAr/N2, total gas content ...


6. GISP2 and Taylor Dome Ice Core N2O Data [NOAA_NCDC_PALEO_2003-054]
Paleoatmospheric records of trace-gas concentrations recovered from ice cores provide important sources of information on many biogeochemical cycles involving carbon, nitrogen, and oxygen. Here, ...


7. Gases in Firn Air and Shallow Ice at the WAIS Drilling Site, Antarctica [sowers_0440759]
Elemental and isotopic composition of firn air and occluded air in shallow boreholes and ice cores from the WAIS Divide site, the location of a deep ice-coring program. The three primary objectives ...


8. Greenland Ice Sheet Project II (GISP2) Ice Core Methane Data, NOAA/NCDC/WDC-Paleoclimatology [NGDC_WDCA_PALEO_GISP2_CH4]
This data set contains methane (CH4) concentration data derived from the Greenland Ice Sheet Project II (GISP2) ice core. The methane concentration was measured from trapped gases in in samples from ...


9. Moulton Gas Data [Sowers_0230021]
Data on the elemental and isotopic composition of O2, N2, Ar and CH4 are reported for three firn cores and two blu-ice cores from the Summit of Mt. Moulton. For the firn cores, we measured ...


10. Vostok (Antarctica) Ice Core N2O Isotope Data from WDC/Paleoclimatology [NOAA_NGDC_PALEO_VOSTOK_SOWERS]
This data set contains isotopes of N2O, d 15N, and d180 (oxygen) taken from the Vostok ice core to 3488 masl.


11. Methane Isotopes in South Pole Firn Air, 2008 [NSIDC-0502]
This data set contains depth profiles for delta carbon-13 (δ13C) and delta deuterium (δD) of methane (CH4) in South Pole firn air. The investigators obtained air samples from ...
