Post-Last Glacial Maximum Thickness
The thickness maps of the Post-LGM deposits can be used to identify areas where i) pre-Holocene submerged landscapes are exposed at or close to the seabed, or, ii) where there is high potential for preservation of early Holocene landscape features such as submerged river valleys or coasts. Contours are presented as depth (metres) below the present seafloor or the base of the post-LGM sedimentary cover. In glaciated regions, the thickness of the Holocene is used.

Data Quality
A harmonised classification of submerged landscape features (landforms and deposits) and palaeoenvironmental indicators utilises existing records (e.g. maps, geophysical data, databases, reports, literature) to assemble an inventory of submerged landscape data. Submerged landscapes features included are: coastal, riverine, subaerial, water points and arhcaeological data. Palaeoenvironmental information will comprise records of flora and fauna and indicators of former sea level. Chronological information (e.g. 14C) will be included as an attribute, and used to assign features to a specific palaeogeographic reconstruction. An assessment of Holocene sediment thickness will be made using existing geological maps and/or borehole databases. The compiled information on submerged landscape features, palaeoenvironmental indicators and age will be used to underpin palaeogeographic reconstructions across various time-frames.
Constraints
The condition is only valid for the submerged landscapes shown on the EMODnet portal. The conditions for the real data held by the partners are probably different. See INSPIRE Directive for more details.
