The Territorial Sea (12 Nautical Mile Limit) dataset builds on previous versions of the world's marine boundaries data, and indicates the 12 nautical mile maritime boundary. This dataset also contains digital information about treaties, joint regime, and disputed boundaries.<br><br>For futher information see: Flanders Marine Institute (2019).

The intertidal environment is one of the last remaining unmapped coastal ecosystems on Earth. Here we present an analysis of over 700,000 satellite images that maps the global extent of and change in tidal flats over the course of 33 years (1984–2016). About 70% of the global extent of tidal flats is found in three continents (Asia (44% of total), North America (15.5% of total) and South America (11% of total)), with 49.2% being concentrated in just eight countries (Indonesia, China, Australia, the United States, Canada, India, Brazil and Myanmar). For regions with sufficient data to develop a consistent multi-decadal time series—which included East Asia, the Middle East and North America—we estimate that 16.02% (15.62–16.47%, 95% confidence interval) of tidal flats were lost between 1984 and 2016. Extensive degradation from coastal development, reduced sediment delivery from major rivers, sinking of riverine deltas, increased coastal erosion and sea-level rise signal a continuing negative trajectory for tidal flat ecosystems around the world.<br><br> For complete information please see: <a href="http://dx.doi.org/10.1038/s41586-018-0805-8"target="_blank">Murray N.
