The MELOA project (https://www.ec-meloa.eu/) proposes to develop a low-cost, easy-to-handle, wave resilient, multi-purpose, multi-sensor, extra light surface drifter for use in all water environments, ranging from deep-sea to inland waters, including coastal areas, river plumes and surf zones. Given the low infuence of wind upon the drifters’ displacements, MELOA will provide a cheap efective way to monitor surface currents and surface dynamic features anywhere in the World Ocean. Through equipping the drifters with thermistors at two diferent levels, the possibility is open for monitoring “ nearskin temperature” and near-surface A complete Software Ecosystem is developed in MELOA to transmit the measurements from the WAVY drifters’ sensors via GPRS or satellite communications (Argos), or Wi-Fi for the raw log fles through a Mobile Application (WavyHub); manage the test campaigns and launches and curating the data through the WAVY Operation Software; generate the Data Products in CSV and O&M formats through the L1 Processor; and disseminate and make the data openly accessible through the Catalogue, Geoportal and Data Services.This work was supported by the project MELOA from the European Commission’s Horizon 2020 research and Innovation program under Grant Agreement No. 776280 . This work uses research infrastructur e s from EGI (INCD and IFCA CSIC -UC) with dedicated support for MELOA.Peer ReviewedPostprint (published version
