Thank you for your inquiry.
You may want to try the OSCAR third degree resolution ocean surface currents dataset, but please note that doesn’t go down to 30m.
The following link will take you to the “dataset information” page: https://podaac.jpl.nasa.gov/dataset/OSC ... _third-deg
On that page will be a “data access” tab, which will take you directly to the data and other provided links and tools.
For visualization over the entire available data period or for interactive sub-setting of data you can use the following LAS tool: http://podaac.jpl.nasa.gov/las
The Live Access Server (LAS) enables you to: visualize data with on-the-fly graphics; request custom subsets of variables in a choice of file formats; access background reference material about the data (metadata); compare (difference) variables from distributed locations. LAS is a highly configurable web server designed to provide flexible access to geo-referenced scientific data.
