Methodology for automated spatial sea ice summaries in the Southern Ocean
Abstract: Sea ice is recognised as a core driver of both ecosystem dynamics and fishery ... dynamics of sea ice in a target location for a specified period, and a temporal view is used to ... during historical fishing events. The distribution of local ice concentration at the time of each fishing ... relationship between sea ice concentration and fishing. Although more than 85% of fishing events occurred in ...
