[1] We collected 1850 km of ground-based radio echosounding (RES) data in West Antarctica along the 2001 US leg of the International Trans-Antarctic Scientific Expedition traverse (US-ITASE). These data represent the first high-resolution measurements of ice thickness and internal stratigraphy for portions of this area that bear on questions about the stability of the West Antarctic Ice Sheet (...

In North America, two slide counting methods have been widely used by aerobiologists: the single longitudinal traverse method and the twelve transverse traverse method. The purpose of this study was to compare the two counting methods by assessing fungal spore concentrations of ascospores...
