Does anyone know where I can find a map of polylines/polygons indicating the rough location of major (and minor if possible) oceanic currents? Velocity is always welcome, but directionality would be ideal.
It would be similar to this map which I believe is only available to ArcGIS users.
This will mainly be used for comparing to other data layers, rather than integrating into the model.
I am using QGIS, and any resolution is okay, but really the finer the better (as always).
