1. Collaborative Research: Microparticle/tephra analysis of the WAIS Divide ice core [dunbar_0636767]
Visible tephra layers were found in the Byrd Station ice core, the first deep core drilled in Antarctica. Since then, tephra have been found in many other Antarctic ice cores. Tephra layers in ice ...


2. Microparticle/Tephra Analysis of the WAIS Divide Ice Core, Antarctica [kreutz_0636740]
This award supports a project to perform continuous microparticle concentration and size distribution measurements (using coulter counter and state-of-the-art laser detector methods), analysis of ...


3. Blue Ice Tephra II - Brimstone Peak [NSIDC-0114]
This data set is the result of a study of volcanic ash and rock fragment (tephra) layers in exposed blue ice areas on Brimstone Peak (75.888S 158.55E) in East Antarctica. Tephra samples were collected ...


4. Blue Ice Tephra II - Mt. DeWitt [NSIDC-0115]
This data set is the result of a study of volcanic ash and rock fragment (tephra) layers in exposed blue ice areas on Mt. DeWitt, Antarctica (77.12 deg S, 159.51 deg E). Tephra samples were collected ...


5. Tephra in Siple and Taylor Dome Ice Cores [NSIDC-0110]
This data set consists of electron microprobe geochemical analyses of glass shards sampled from Siple Dome and Taylor Dome ice cores during the 1999-2000 field season. Geochemical data are in tab-delimited ...


6. Physical and Structural Properties of the Siple Dome Ice Cores [NSIDC-0128]
This data set is part of the WAISCORES project, an NSF-funded project to understand the influence of the West Antarctic ice sheet on climate and sea level change. WAISCORES researchers acquired and ...


7. Volcanic Records in the Siple and Taylor Dome Ice Cores [NSIDC-0126]
This data set is part of the WAISCORES project, an NSF-funded project to understand the influence of the West Antarctic ice sheet on climate and sea level change. WAISCORES researchers acquired and ...


8. Collaborative Research: Refining a 500-kyr Climate Record From the Mt. Moulton Blue Ice Field in West Antarctica [dunbar_NSF0230348]
There is intense scientific interest in the history, dynamics and future of the West Antarctic Ice Sheet because it is the world's only remaining marine ice sheet and is considered by ...


9. Dry Valleys Geomorphology from Boston University [BU-054-001]
The data set includes trace-element geochemical analyses of volcanic tephra, geochronologic data for Dry Valleys ashfall deposits, and locations and description of soil pits in the Antarctic ...


10. Geochemical and radiometric age data on core samples from the Cape Roberts Project, Western Ross Sea, Antarctica. [Kyle-Cape_Roberts]
1. 40Ar/39Ar dates of minerals separated from pumiceous tephra layers in the core from Cape Roberts Project cores 1 and 2. 2. Major and trace element analyses of fine grain sediment ...


11. Catalog of Mount St. Helens 2004 - 2005 Tephra Samples with Major- and Trace-Element Geochemistry [USGS_OFR_2008_1131]
This open-file report presents a catalog of information about 135 ash samples along with geochemical analyses of bulk ash, glass and individual mineral grains from tephra deposited as a result of ...


12. Late Pleistocene paleolakes in Andean and Extra-Andean Patagonia at mid-latitudes of South America [CDA_AR_GEO_PATAGONIA_PALEOLAKES]   PARENT DIF
Late Pleistocene paleolakes on the eastern side of Andes (glacial lakes) and in the Patagonian Steppe (pluvial lakes)along 41?S latitude were studied. Natural Dams (glaciers, moraines) that maintained ...
