Illustration of the emerging capabilities of SARAL/AltiKa in the coastal zone using a multi-platform approach

•Glider data were acquired along a SARAL/AltiKa track in August 2013 in the Ibiza Channel.•Satellite altimetry, HF radar and glider data are interpolated and filtered to compute the cross-track velocity.•All the platforms showed the existence of a 25–30km width coastal jet with velocities larger than 20cm/s.•Filtered 40Hz data provided geostrophic current about 10km from the coast.
