Hello fellow Expedition users, I have been trying to find current gribs for the great lakes which can be read in expedition.  The expediton grib server does have Mercator and LOF Great Lakes options however they always download null value or errors.  Tidetech also told me a few years ago they didnt offer Great Lakes currents.  

However, NOAA has currents plot animations available on their website along with multiple download options for raw data,  I have however never been able to download any format which Expedition will read.  (OFS Map Plots)

Has anyone here ever worked with Great Lakes Currents?  

Thanks!
