The metadata catalogue stores information about Atlantic data, reused or relevant for MISSION ATLANTIC. The philosophy of this catalogue is « collect once, reuse many times ». It provides a customized discovery service to users, facilitating access to existing services such as viewing and downloading data as well as informing users about the data resources available.

The content of the catalogue is various resources shared by regional Case Studies in MISSION ATLANTIC such as data products, models, classifications, tools, programs, and relevant projects. This compilation represents data needs for IEAs to perform precise and accurate ecosystem analysis (WP1), as well as mapping of pelagic and benthic pressures (WP3-4), modelling for prediction (WP6), and descriptive statistics on the raw data for assessing the state of ecosystems (WP5). This catalogue is hosted by Sextant and based on EMODnet Standards.
