Abstract
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.
