1. An environmental record of lead isotopes over four centuries at Law Dome, Antarctica [ASAC_1092]
Antarctic ice provides an archive of Earths atmospheric composition over time. It therefore records evidence of human impact on the atmosphere. Lead is a toxic element, whose isotopic fingerprint ...


2. Lead isotopes in snow and ice as an indicator of past changes to the Antarctic environment [ASAC_966]
From the abstracts of the referenced papers: Techniques for Pb measurements have reached the stage where Antarctic ice with sub-picogram per gram concentrations can be reliably analysed for isotopic ...


3. Collaborative Research: Molecular Level Characterization of Organic Matter in Ice Cores using High-resolution FTICR mass spectrometry [hatcher_0739684]
This award supports a project to fully develop the analytical protocols needed to exploit a relatively new technique for the analysis of soluble organic matter in ice core samples. The technique couples ...


4. Alkanes in Firn Air Samples, Antarctica and Greenland [NSIDC-0504]
This data set contains ethane, propane, and n-butane measurements in firn air from the South Pole and the West Antarctic Ice Sheet (WAIS) Divide in Antarctica, and from Summit, Greenland. The WAIS ...


5. Hydrographic Parameters from Fram Strait and Denmark Strait, 1998 [ARCSS105]
This data set includes data for the following parameters: dissolved barium; bottom depth; pressure; temperature; salinity; dissolved oxygen; phosphate; siliceous acid; nitrate; nitrite; and oxygen ...


6. SAFARI 2000 PLANT AND SOIL C AND N ISOTOPES, SOUTHERN AFRICA, 1995-2000 [s2k_plant_soil_c_n]
This data set contains measurements of the concentration and stable carbon (13C / 12C) and nitrogen (15N / 14N) isotope ratios of plant (leaves, roots and fungi) and soil samples from southern Africa. ...


7. Firn Air Isotope and Temperature Measurements from Siple Dome and South Pole [NSIDC-0098]
This data set includes d15N, d18O/2, dO2/N2/4, d40Ar/4, d38/Ar/2, d84Kr/48, and d132Xe/96 values for air drawn from the top 15 to 50 m of firn at the South Pole (summer and winter 1998) and a site ...


8. Arctic Ocean Barium Concentrations, 1993 [ARCSS102]
This data set includes measurements of barium concentrations in samples collected during five oceanographic cruises in the Arctic Ocean in 1993. Investigators collected water samples with Niskin, ...


9. Barium Concentrations and Salinity in Arctic River Estuaries, 1993-1996 [ARCSS107]
This data set includes measurements of barium concentrations and salinity in samples collected from the estuaries of major Arctic rivers and adjacent shelf areas during 1993 to 1996. Investigators ...


10. Analysis of Siple Dome Ice Core: Carbonyl Sulfide (COS), Methyl Chloride (CH3Cl), and Methyl Bromide (CH3Br) [NSIDC-0279]
This data set is part of the WAISCORES (West Antarctic Ice Sheet cores) project, research funded by the National Science Foundation (NSF) and designed to improve understanding of how the West Antarctic ...


11. Denitrifying Activity in Deep Soil Profiles [USDA0406]
The "Denitrifying Activity in Deep Soil Profiles" dataset contains data on what factors control denitrifying activity in deep soil profiles. Its purpose is to evaluate an N-based method for measuring ...


12. ORGCHEM Petroleum Source Rock Database; BMR, Australia [EARTH_CRUST_AUS_BMR_Petrol_DB1]
ORGCHEM is a relational database that contains organic geochemical data used for petroleum source rock assessment. The majority of data is from petroleum exploration wells drilled offshore and onshore ...
