The goal of this project is to launch a new satellite (called SKIM) and use the data for analyzing ocean currents and waves. SKIM is a proposal for the Earth Explorer 9 that ESA plans to launch before 2025. If you want to work with existing data on currents, you can look back at the Envisat data. For waves, there are quite a few options but the interesting stuff will be CFOSAT, due for launch in 2018.
