Ice Shelf - Sea Ice Interaction: A Case Study
Here we present results from our investigation on the influence of the Ekström Ice Shelf on the land-fast sea ice of Atka Bay, eastern Weddell Sea. • Ice platelets emerge from the cavity and interact with the fast-ice of Atka Bay as early as June. Episodic accumulations throughout the winter lead to...
