Delta Relict delta landform formed by deposition of sediment transported via river as it enters slower-moving / stagnant body of water such as a marine environment, lake or estuary. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

A palaeo-alluvial plain is defined as a largely flat landform created by the repeated deposition of alluvial sediments over a long period of time by running water. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

Pan-European coastline-migration map at zoomable scale. The map is collated and harmonized from field-monitoring data and aerial photography provided by partners of EMODnet Geology. Where no such coastline-migration data were available, information from the EUROSION project is provided. For remaining gaps, please consult the coastline-migration map based on satellite data. The main attributes denote degree of landward (by erosion or submergence) or seaward (by accretion or emergence) change. In the visualization provided, three classes are distinguished: landward migration, stable coastline, seaward migration. The criterion for stable coastlines is ≤0.5 meter net change per year over a 10-year period. The current version was finalized in January 2021.

Coastal landscape underlain by limestone which has been eroded by dissolution, producing ridges, towers, fissures, sinkholes and other characteristic landforms. Where known the type of karst e.g. limestone, dolomite, evaporitic rocks, sinkholes, boulder piles etc. is stated. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

Relict estuary landform defined as a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it and a free connect to the open sea/ocean. Where know the type of estuary (e.g. fjord, estuary, ria) is included. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

Coastal Landforms created during periods of lower sea level. These features may or may not be submerged today (e.g. as a result of isostatic rebound). Where possible these have been subdivided into the type of Coastal Landform e.g. Beachrock, Littoral deposit, Coastal dunes, Cliff, Sand bars, beach ridges, Other. Where information is available on the genesis of the beach deposit this has been provided, e.g. foreshore sediment, aeolian sediment (e.g. dunes). Where information on sediment grain size and composition is available this has been provided. Uncemented/cemented (e.g. beach rock). Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

Polyline defining the margin of a former delta. A delta is formed by deposition of sediment transported via river as it enters slower-moving / stagnant body of water such as a marine environment, lake or estuary. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.

Last Glacial Maximum (LGM) landscape / base of the post-LGM deposit. Contours are presented as depth (metres) below present mean sea level of the post LGM sedimentary cover. This is an erosional unconformity, where an infilled valley is present the valley base has been used. LGM defined on average at 18,000 years BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only, 4. Low: Reasonable without any direct evidence

Coastal landscape underlain by limestone which has been eroded by dissolution. Where known this has been subdivided thus: 1. Caves; 2. Sinkholes; 3. Solution pans; 4. Cockpits; 5. Karst cones; 6. Towers; 7. Boulder piles; 8. Tor; 9. Other. Note that we are using the term ‘sinkhole’ to include dolines, cenotes and swallow holes. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.
