The datasets contains a classification of the world’s mangroves based on their geomorphic and sedimentary setting, and divides the global mangrove extent into 4,318 macroscale units. The timeseries contains five layers. One each for the 1996, 2007, 2010 and 2016 Global Mangrove Watch mangrove extents and a composite layer that combines those four timesteps.

Mangroves are classified as deltaic, estuarine, lagoonal or open coast based on their proximity to coastal features. The mangrove units are assigned to a sedimentary setting with all deltaic and estuarine units classed as terrigenous (i.e. dominated by minerogenic sedimentation from terrestrial sources). Whereas, lagoonal or open coast patches could be classed as terrigenous or carbonate (i.e. dominated by calcareous sedimentation). The dataset provides a framework for considering geomorphic and sedimentary setting when quantifying mangrove ecosystem services or restoration potential.
