Summary
Abstract: This data set contains sub-annually resolved concentrations of hydrogen peroxide (H2O2), snow, firn and ice from 23 sites on the West Antarctic Ice Sheet (WAIS. Data were obtained from 2000 to 2003 during the US International Trans-Antarctic Scientific Expedition (US ITASE) deployments. Cores were drilled approximately every 100-300 kilometers down to depths of up to 120 meters. H2O2 was measured in snow, firn, and ice using a fluorescence detection method either in situ after sampling or in the lab 9-12 months after sample collection. Depending on local accumulation rate, up to 500 year long records were obtained from the WAIS region (76-90ºS / 84-124ºW). Core H2O2 concentrations are reported in parts per billion by weight (ppbw) as a function of decimal year. Data are available via FTP as ASCII text files (.txt).
