A broad range of oceanographic and environmental conditions and processes influence marine ecosystems and fisheries. The Seychelles Digital Ocean Atlas (SDOA) is designed to provide to an easy access to information on the marine environment. The datasets associated to this first version include ocean numerical models (since 1993) and satellite sea colour (since 1997). An interactive web interface allows the user to generate maps, time series, transects, space-time and vertical plots of thirteen variables (seven physical and 5 biogeochemical variables, and the GEBCO seafloor topography) that are included in this version. The SDOA area stretches over an area of 5.2 million km² including the Seychelles Exclusive Economic Zone and neighbouring regions (5°N to 13°S, 41°E to 70°E). The SDOA system is flexible as it can easily include new variables (gridded or discrete) without huge development effort. The SDOA is also fully expandable to other regions, as the code and users interface can be applied to other NetCDF datasets generated specifically for other study areas. Eventually, the SDOA can provide useful information in a blue economy context.
