The European Commission set up the European Marine Observation Data Network (EMODnet) six years ago. It is a network of more than 100 organisations working together to observe and measure the oceans, process the data according to international standards and then make that information freely available. Usually, the data are collected via local, national and regional databases and then made available via EMODnet's central information gateway as interoperable data layers and data products.
Human Activities is a relatively new discipline added to the EMODnet central portal. The aim is to map all sea-related human activities concerning for example mariculture, fisheries zones, main ports (i.e. transport of goods, passenger and vessels), cultural heritage, and many other. The map provides aggregated data on the geographical position and spatial extent of the activities concerned, their temporal variation, time when data was provided, and attributes to indicate the intensity of each activity. Data are collected and updated on a permanent basis, subject to their availability. The portal has been designed to make it easy to search for information.
