The Ocean Data Viewer (ODV) offers users the opportunity to view and download a range of spatial datasets of biodiversity importance that are useful for informing decisions regarding the conservation of marine and coastal biodiversity. EcosystemsCoastalOpen ocean MethodsLife cycle analysisMapping/GIS TopicsAquacultureDirect use value Additional informationTo complement the ODV, the Manual of marine and coastal datasets of biodiversity importance (http://wcmc.io/MarineDataManual) was created to provide an overview of more than 100 global marine and coastal datasets, with detailed metadata sheets for more than half of these. A list of all datasets can be downloaded from the following link: http://wcmc.io/ODV_data. For a more detailed resource of known marine and coastal datasets globally, please see Annex 2 of the Manual of marine and coastal datasets of biodiversity importance (pp. 32-42). ConstraintsPlease read the associated metadata for each dataset to determine appropriate dataset uses and limitations. Product requirementsAvailable in standard GIS formats, while a simple mapping interface enables users to explore individual datasets and overlay them with other data layers. AdvantagesOnline data repository where multiple layers can be selected and assessed online. Metadata can also be downloaded for personal use and research.Provides current and reliable data on global, regional and national marine and coastal biodiversity to enable progression to towards multilateral environmental agreements.
