1. WAIS Divide Sonic Log Data [NSIDC-0592]
This data set contains a record of speeds for vertically-propagating compression-waves measured throughout the depth of ice that surrounds the WAIS-D borehole. Multiple logs provide redundant measurements ...


2. Temperature Profile of the West Antarctic Ice Sheet Divide Deep Borehole [NSIDC-0550]
This data set reports depth versus temperatures in the fluid-filled portion of the West Antarctic Ice Sheet Divide (WAIS–D) deep borehole (70 to 3328 meters depth). Data were acquired on December ...


3. Methane Concentrations from the WAIS Divide Ice Core (WDC06A), 60 to 11,300 ybp [NSIDC-0509]
This data set contains a high-resolution history of atmospheric methane (CH4) concentrations in parts per billion (ppb) from approximately 60 to 11,300 years before present (ybp), obtained in 2010 ...


4. Late Holocene Methane Concentrations from WAIS Divide and GISP2 [NSIDC-0586]
This data set measures methane concentrations in ancient air trapped in the West Antarctic Ice Sheet (WAIS) Divide and Greenland Ice Sheet Project (GISP2) ice cores; presenting two, high-resolution ...


5. Cosmogenic Radionuclides in the WAIS Divide Ice Core [welten_0636964]
This dataset includes a record of the concentrations of the cosmogenic radionuclides, 10Be (half-life = 1.36 x 10^6 year) and 36Cl (3.0 x 10^5 year), in samples from the West Antarctic Ice Sheet (WAIS) ...


6. Collaborative Research: Stable Isotopes of Ice in the WAIS Divide Deep Ice Core [cuffey_0537661]
This award supports analyses of stable isotopes of water, dD, d18O and deuterium excess in the proposed West Antarctic Ice Sheet Divide (WAIS) deep ice core. The project will analyze a continuous ...


7. Spatial Variability in Firn Properties from Borehole Optical Stratigraphy at the Inland WAIS Core Site [waddington_0538639]
