Short summary
Moored observations confirm that strong ocean surface stress events ("storms'') can increase the speed of the Antarctic Slope Current and the circulation in the Filchner Trough region. Roughly 25 % of the identified storm events also cause an increased southward current speed on the continental shelf. Such enhanced circulation on the shelf increases the likelihood that warm summer inflow reaches the Filchner Ice Front and cavity before it is lost to the atmosphere during winter.
