A new family of multi-purpose, multi-sensor, small sized, easy-to-handle, low-cost, spherical surface drifters is about to appear in the market, with its first three models. The WAVY Ocean is a current, wave and near-surface temperature gradient tracker for the open Ocean; the WAVY Littoral is a current and wave tracker designed for nearshore operations; and the WAVY Basic is a current and nearsurface temperature tracker intended for riverine and estuarine environments, and suitable for citizen science. The WAVY optimized buoyancy - only 30% of the axes above the surface - ensures that their displacement is essentially due to the current, while their small size makes them sensitive to the average vectors in the very near surface. Examples of WAVY Ocean full resolution data from recent observations illustrate the performance and the potential of these drifters in operational missions requiring near-real time data of the very near surface of the ocean.This is a contribution to Project MELOA (Multipurpose/Multi-sensor Extra Light Oceanography Apparatus - H2020-SC5-2017-OneStageB).
