Collaborative Research: The Role of Glacial History on the Structure and Functioning of Ecological Communities in the Shackleton Glacier Region of the Transantarctic Mountains |
During the 2017-2018 austral summer, 220 surface soil samples (~top 5 cm) were collected from 11 distinct ice-free areas (Roberts Massif, Schroeder Hill, Mt. Augustana, Bennett Platform, Mt. Heekin, Thanksgiving Valley, Taylor Nunatak, Mt. Franke, Mt. Wasko, Nilsen Peak, and Mt. Speed) along the Shackleton Glacier. Dried soils were leached at a 1:5 soil to DI water ratio, and the leachate was filtered through 0.4 µm Nucleopore membrane filters. The leachate was analyzed for anions (F-, Cl-, Br-, and SO42-) which were measured on a Dionex ICS-2100 ion chromatograph, cations (K+, Na+, Ca2+, Mg2+, and Sr2+) which were measured on a PerkinElmer Optima 8300 Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES), and nutrients (NO3- + NO2-, PO43-, H4SiO4, and NH3) which were measured on a Skalar San++ Automated Wet Chemistry Analyzer at The Ohio State University. Perchlorate (ClO4-) and chlorate (ClO3-) were measured using an ion chromatograph-tandem mass spectrometry technique (IC-MS/MS) at Texas Tech University. Accuracy was typically better than 5% for all major anions, cations, and nutrients, as determined by the NIST 1643e external reference standard and the 2015 USGS interlaboratory calibration standard (M-216), and better than 10% for perchlorate and chlorate, as determined by spike recoveries. | ["POLYGON((-177.4213 -84.4647,-177.08802 -84.4647,-176.75474 -84.4647,-176.42146 -84.4647,-176.08818 -84.4647,-175.7549 -84.4647,-175.42162 -84.4647,-175.08834 -84.4647,-174.75506 -84.4647,-174.42178 -84.4647,-174.0885 -84.4647,-174.0885 -84.56732,-174.0885 -84.66994,-174.0885 -84.77256,-174.0885 -84.87518,-174.0885 -84.9778,-174.0885 -85.08042,-174.0885 -85.18304,-174.0885 -85.28566,-174.0885 -85.38828,-174.0885 -85.4909,-174.42178 -85.4909,-174.75506 -85.4909,-175.08834 -85.4909,-175.42162 -85.4909,-175.7549 -85.4909,-176.08818 -85.4909,-176.42146 -85.4909,-176.75474 -85.4909,-177.08802 -85.4909,-177.4213 -85.4909,-177.4213 -85.38828,-177.4213 -85.28566,-177.4213 -85.18304,-177.4213 -85.08042,-177.4213 -84.9778,-177.4213 -84.87518,-177.4213 -84.77256,-177.4213 -84.66994,-177.4213 -84.56732,-177.4213 -84.4647))"] | ["POINT(-175.7549 -84.9778)"] | false | false |

Snow-Atmosphere Transfer Function for Reversibly Deposited Chemical Species in West Antarctica |
This data set is part of the West Antarctic Ice Sheet Cores (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 analyzed snow pit and core samples from the Siple Dome, in the Siple Coast region, West Antarctica. This data set includes glaciochemical spatial variability data for six Siple Dome snow pits. Samples involved measuring hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) and formaldehyde (HCHO) in the air, snow, firn, and ice via suppressed ion chromatography. The data can be used to interpret changes in concentrations of these species recorded in ice cores.

Siple Dome Deep Ice Core Glaciochemistry and Regional Survey - A Contribution to the WAIS Initiative |
This data set is part of the West Antarctic Ice Sheet cores (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 analyzed snow pit and core samples from the Siple Dome, in the Siple Coast region, West Antarctica. This data set includes glaciochemical spatial variability data for Siple Dome snow pits B, E, F, G, H, and 1 through 6. Samples were analyzed for soluble ion content via suppressed ion chromatography. Each pit was sampled at 2 cm resolution for ion chemistry using clean procedures, and sampled again at 3 cm resolution for density calculations. Snow pit names and locations correspond to the 1996 to 1997 season shallow core sites. Data in this collection were obtained during two Antarctic field seasons in 1994 to 1995 and 1996 to 1997. Data are available via FTP in space-delimited ASCII text (.dat) file format. | ["POLYGON((-149.11 -81.05,-149.05 -81.05,-148.99 -81.05,-148.93 -81.05,-148.87 -81.05,-148.81 -81.05,-148.75 -81.05,-148.69 -81.05,-148.63 -81.05,-148.57 -81.05,-148.51 -81.05,-148.51 -81.11,-148.51 -81.17,-148.51 -81.23,-148.51 -81.29,-148.51 -81.35,-148.51 -81.41,-148.51 -81.47,-148.51 -81.53,-148.51 -81.59,-148.51 -81.65,-148.57 -81.65,-148.63 -81.65,-148.69 -81.65,-148.75 -81.65,-148.81 -81.65,-148.87 -81.65,-148.93 -81.65,-148.99 -81.65,-149.05 -81.65,-149.11 -81.65,-149.11 -81.59,-149.11 -81.53,-149.11 -81.47,-149.11 -81.41,-149.11 -81.35,-149.11 -81.29,-149.11 -81.23,-149.11 -81.17,-149.11 -81.11,-149.11 -81.05))"] | ["POINT(-148.81 -81.35)"] | false | false |
Newall Glacier Snow Pit and Ice Core, 1987 to 1989

Characterization of Climatic Events for the Last 2 x 103y through the Retrieval of Ice Cores from the Transantarctic Mountains, Antarctica |
Snow pit and ice core data from the Newall Glacier (location - 162 30' East, 77 35' South) were collected during 1987 and 1988. These include information on chemistry, Beta profiles and stratigraphy. Ice cores were collected during the austral summer of 1988-1989 and contain information on chemistry, Pb- 210 profiles, density profiles and temperature profiles. Core A was 175 meters long and core B was 150 meters long. The snow pits were dug and sampled by the Glacier Research Group (GRG), using established protocols to prevent contamination. The samples for major ion chemistry remained frozen until melted for analysis in the GRG lab, located at the University of New Hampshire (UNH), and all core processing was done by GRG established protocols to prevent contamination. Major ions were analyzed using suppressed ion chromatography. | ["POINT(162 -77)"] | ["POINT(162 -77)"] | false | false |
Dronning Maud Land, Antarctica, Ice Core, 1991 and 1992
|
None | 1999-01-01 | Whitlow, Sallie; Mayewski, Paul A. | No project link provided | Major ion concentration values (Na, Mg, Ca, Cl, NO3, SO4, MSA) were analyzed from a 20-meter ice core drilled in Dronning Maud Land, Antarctica (location - 65 01' East, 75 00' South, elevation - 2,900 m a.s.l.). The core was drilled during the austral summer 1991-1992. Major ion analysis was by ion chromatography. The anions were analyzed on a Dionex AS4A column; the cations on a Dionex CS12 column and MSA on a Dionex AS4 column. All used suppressed chromatography. Using established protocols to prevent contamination, the core was processed into 3-centimeter pieces by the Glacier Research Group at the University of New Hampshire's Climate Change Research Center. The 3-cm pieces were kept frozen until major ion analysis. | ["POINT(65 -75)"] | ["POINT(65 -75)"] | false | false |
