Seasonal surface melt onset and firn freeze-up across the central Wrangell and St. Elias Mountains

Abstract. High-elevation alpine firn is increasingly influenced by surface melt and meltwater retention, yet the spatial extent and timing of these processes remain poorly quantified. Here we present spatially distributed estimates of seasonal surface melt onset and firn freeze-u...

Trends in south pole particle concentrations imply holocene westerly wind strengthening

The Southern Hemisphere Westerly Winds (SHWW) play an important role in global climate and Antarctic ice sheet dynamics; however, high-resolution proxy reconstructions are sparse. Conflicting evidence suggests SHWW latitudinal change, weakening and/or strengthening, throughout th...
