Variability and trends in the ocean conditions form a set of information that can be used in fisheries management, inshore and offshore, and assist in spatial planning to design specific boundaries in the areas under national jurisdiction of the coastal states. A French funding (FSPI) dedicated to develop innovative projects in the Blue Economy space in 2021-2022, has been the opportunity to develop an online digital ocean atlas for Seychelles . This project is run jointly by a locally-based software development company and a research institute. The project is developing a web-based application to produce a variety of outputs, such as maps, line plots, hovmoller plots and vertical profiles. Here, we present the variables handled by the atlas, the various functionalities, the expected deliverables and the requirements set for the database management and the programming language in order to conform with international standards.
