A 2000-year record of arsenic variability from a South Pole ice core
Using a South Pole ice core covering the last ~2050 years we present a high-resolution (4-27 samples/year), continuous record of natural and anthropogenic arsenic (As) deposition. Our results show that volcanic emissions (notably from Mt. Erebus) are a significant source of As for South Pole, and hu...
