Notes
The data contains tracks of individual eddies and their characteristics, specifically it contains following variables, for anticyclones and cyclones separately: "Eddy identifier": Unique number assigned to each eddy track; "Eddy tracking time step": Counter for the number of time steps the eddy has been tacked, starting with 1 for each eddy track; 1 time step corresponds to 7 days; "Longitude": Longitude of eddy center; "Latitude": Latitude of eddy center; "Diameter": Diameter of a circle covering the same area as the respective eddy; "Log base 10 chlorophyll": Chlorophyll averaged over eddy area; "Log base 10 chlorophyll anomaly": Chlorophyll anomaly averaged over eddy area; "Log base 10 background chlorophyll": Background chlorophyll averaged over eddy area; "Year", "Month", "Day": Date of eddy snapshot.
