资源简介:
Five shallow (~20-m) ice cores were collected in November/December 1999 near
South Pole. All cores were collected within 20 km of the Pole and were located
to sample high, moderate, and low snow accumulation regimes based on earlier
work by Mosley-Thompson et al. The cores were analyzed using a continuous
melter system for hydrogen peroxide, nitrate, liquid conductivity, and, for
some core sections, formaldehyde. Mean snow accumulation rates were confirmed
using beta radioactivity horizons.
