MELOA Project

Running since 2017, MELOA (Multi-purpose/Multi-sensor Extra Light Oceanography Apparatus) is an H2020 project that is developing an innovative family of products, WAVY drifter units, allowing for a low-cost, easily deployable, high versatility, and low maintenance system for in-situ measurements for marine environments.


Focused on covering marine observation gaps, the WAVYs will increase the availability of in-situ data for coastal and open ocean zones. The MELOA project is developing the first prototypes for the different WAVY units configurations, and engaging with the marine community to test them in different marine environments, collecting and making available the data from the test campaigns and building, on top of this data, the first products and services to showcase the usefulness of the WAVY data.


Initially planned to end by 2021, the project received an extension until February 2022, as the MELOA team was forced to interrupt the activities involving the development and testing of the WAVY drifters and cancelled all community international events during 2020. With this extension, the team will have enough time to achieve the goals set for the development of the family of WAVY drifters. 


MELOA Consortium is composed by 10 European entities working in close collaboration with the marine communities to develop solutions that will enable to tackle some societal challenges, namely those related in situ data collection for marine monitoring.

MELOA is developing a family of WAVY drifters to:




Address different use cases for marine in-situ measurements, including the most remote oceanic areas.

MELOA is developing small-sized WAVYs, for beach and surf zone studies, for coastal and long-term open ocean observations.



Generate valuable in-situ data and derived data products for the GEOSS  and Copernicus programmes.
The data gathered in the test campaigns and open calls will be made available, and linked to GEOSS and Copernicus, via an online catalogue.



Open new opportunities for market de­velopment of the marine commercial sector and for down­stream users.

New commercial opportunities for services based on the in-situ marine data are being explored close to potential users and in the marine community.



Provide data and information to implement the Sustainable Development Goals.

MELOA is laying the foundations for low-cost devices for marine observation systems, while fostering innovation and contributing to the SDGs 9, 13 and 14.

Inter-Project Links

MELOA aims to promote a continuously cooperation and integration of efforts among other projects and initiatives contributing to ocean observing and monitoring activities, at an international level. Currently, MELOA is already estabelishing contacts with inter-project links opportunities to be considered for collaborations and fostering of synergies in different intervention areas.
