About the Ocean Data Viewer

The Ocean Data Viewer offers users the opportunity to view and download a range of spatial datasets that are useful for informing decisions regarding the conservation of marine and coastal biodiversity. These decisions ultimately affect the ocean's health and productivity, which provide the ecosystem services that are necessary for our well-being, livelihoods, and survival. To date, the users of this tool have included government agencies, scientists, researchers, the corporate sector, and non-governmental organisations.

These data come from internationally respected scientific institutions and other organisations that have agreed to make their data available to the global community, with the hope that these data will support and encourage informed decision-making that sustains global biodiversity and ecosystem services.

The Ocean Data Viewer is primarily a mechanism to view and download data, and is not intended to be used for analysis or to query data.

Are we missing data? We welcome feedback and contributions of additional or corrected datasets. Please contact us at marine@unep-wcmc.org.

What resources are available? We encourage data users to read the Ocean+ Habitats User Manual as an introduction to the various challenges, gaps and limitations that can be presented by coastal and marine datasets, and particularly by those at the global scale. Data users may also be interested in the Ocean+ Data website, which provides a list of more than 180 known datasets, database, and data portals containing marine and coastal data and information of biodiversity importance. If you have suggestions of how this site could be improved, or would like to suggest additional marine and coastal data sources, please contact Lauren Weatherdon, Juliette Martin or Osgur McDermott Long

Frequently Asked Questions

What are the requirements for using these datasets? Please note that data users are obliged to cite the datasets they use, as outlined on the ‘dataset detail’ pages and in the associated ‘metadata’ sheets. Users should also review the terms and conditions of use for each dataset before downloading.

How can I search for datasets? The ‘search and filter’ panel allows users to select datasets by keywords, publication dates, categories, formats or data types, and geographical ranges. Click on ‘reset’ to clear all filters and view the full list of datasets.

Where can I view a list of all datasets on the Ocean Data Viewer? A list of datasets can be downloaded from the following link: http://wcmc.io/ODV_data. A more detailed list of known marine and coastal data resources globally can be found at Ocean+ Data.

Can I view multiple datasets at once? More than one dataset may be selected, with the order of appearance depending on the order of selection. For example, if the user wishes to see ‘mangroves’ on top of ‘protected areas,’ then the ‘protected areas’ layer should be selected first, followed by the ‘mangroves’ layer.

How can I navigate the map? Users can use the ‘hand’ to navigate the map. To zoom in and out, use the + and – buttons (top-right of the screen).

Where can I find the version of the dataset? Where applicable, versions are noted for each dataset on the main page and in the associated metadata and citation. Datasets that are new or have been updated within the last 30 days are highlighted using tags.

Where can I download the data and find more information? The ‘dataset detail’ page provides more information on a particular dataset, including a downloadable ‘metadata’ sheet, access to a ‘factsheet’ on the Biodiversity A-Z website, access to the dataset in GIS format, a link to the dataset at ArcGIS Online, and policies of relevance. Please note the ‘use constraints’ for each dataset.
