Intraseasonal changes in aeolian deposition rates in Ebba Valley, central Spitsbergen
Abstract
This study investigates seasonal variations in aeolian deposition within the Ebba Valley, focusing on a single summer season 2022. Measurements revealed that aeolian deposition rates were low at the start of the season, ranging from 0.3 to 0.6 g·m−² per day, but peaked at 25.4 g·m−² per day towards the end of the season. The findings suggest that late summer conditions, with stronger winds and higher precipitation, including lower river water levels and the availability of fresh fluvioglacial material, may enhance aeolian deposition. Understanding these dynamics is crucial for modelling aeolian processes in the context of ongoing climate change.
