Blue ice is found in areas of Antarctica where katabatic winds, focussed by steep surface slopes or by topography around nunataks, cause enhanced surface ablation. This process draws up deeper, older ice to the ice sheet surface, often bringing with

Predicting the West Antarctic Ice Sheet's response to future warming is hindered by a lack of historical evidence. Here, based on geomorphological evidence from and cosmogenic dating of Ellsworth Mountains' deposits, the authors show that at least a

Jan Mayen is a small volcanic island situated 550 km north of Iceland. Glacial sediments and landforms are relatively common on the island but, so far, only a few of them have been dated. In this study, we present and discuss 89 36Cl dates of primari

The broken phosphorus (P) cycle has led to widespread\udeutrophication of freshwaters. Despite reductions in anthropogenic\udnutrient inputs that have led to improvement in the chemical\udstatus of running waters, corresponding improvements in their\

As cosmogenic nuclide applications continue to expand, the need for acommon basis for calculation becomes increasingly important. In order toaccurately compare between results from dierent nuclides, a single methodof calculation is necessary. Calcula
