Life history and phylogenetic/geographic data was combined with oceanographic data to test models of population structuring by oceanographic processes. The data are solely model outputs; specifically high-resolution flows for the South Georgia region and fish egg and larval distributions from different spawning sites.

|Data Collection:||Global current fields from OCCAM (Ocean Circulation and Climate Advanced Modelling Project) were used to drive Individual Based Models (IBMs) to predict the transport of fish eggs and larvae at the circumpolar scale, and population connectivity. To investigate transport and retention patterns at a finer scale, a high resolution hydrodynamic model was developed for the South Georgia region using POLCOMS (Proudman Oceanographic Laboratory Coastal-Ocean Modelling System). Predicted flow fields were used to drive IBMs to simulate fine scale patterns of fish egg/larval retention and shelf-open ocean exchange.|
