Submerged archaeological sites subdivided as: 1. Cave site; 2. Open air site; 3. Settlement; 4. Other. 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.

Submerged forest is defined as the in situ remains of trees (especially tree stumps) that now lie submerged beneath a bay, sea, ocean, lake, or other body of water. Chronological information on method used (e.g. dendrochronology, radiocarbon dating, based on indirect evidence etc.) and age as calendar age BP is included where known. 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.

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 map of submarine landslide susceptibility in European seas. High susceptibility values indicate a high probability of landslides. This map cannot be compared to the accuracy of studies based on detailed investigations, but provides an overall view on the distribution of landslides susceptibility. The map indicates the probability that landslides may occur in that portion of the seafloor over time, but does not measure when or how frequently an event may occur, nor its possible size. For more details refer to: “Submarine landslides: mapping the susceptibility in European seas”, C. Innocenti, L. Battaglini, S. D'Angelo and A. Fiorentino, Quarterly Journal of Engineering Geology and Hydrogeology, 54, qjegh2020-027, 23 October 2020, https://doi.org/10.1144/qjegh2020-027

Thickness of the Last Glacial Maximum (LGM) deposit. Contours are presented as depth (metres) below present seafloor or the base of the post LGM sedimentary cover. LGM is defined on average at 18,000 years BP. In glaciated regions the thickness of the Holocene is used. 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

''' Short description: ''' For the Black Sea - the CNR diurnal sub-skin Sea Surface Temperature product provides daily gap-free (L4) maps of hourly mean sub-skin SST at 1/16° (0.0625°) horizontal resolution over the CMEMS Black Sea (BS) domain, by combining infrared satellite and model data (Marullo et al., 2014). The implementation of this product takes advantage of the consolidated operational SST processing chains that provide daily mean SST fields over the same basin (Buongiorno Nardelli et al., 2013). The sub-skin temperature is the temperature at the base of the thermal skin layer and it is equivalent to the foundation SST at night, but during daytime it can be significantly different under favorable (clear sky and low wind) diurnal warming conditions. The sub-skin SST L4 product is created by combining geostationary satellite observations aquired from SEVIRI and model data (used as first-guess) aquired from the CMEMS BS Monitoring Forecasting Center (MFC). This approach takes advantage of geostationary satellite observations as the input signal source to produce hourly gap-free SST fields using model analyses as first-guess. The resulting SST anomaly field (satellite-model) is free, or nearly free, of any diurnal cycle, thus allowing to interpolate SST anomalies using satellite data acquired at different times of the day (Marullo et al., 2014).

The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project between 2017 and 2021.The scale varies between 10 000 and 5 000 000.

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.

Quaternary – age This web map service shows the chronostratigraphic age of geological units of the seafloor originated in the Quaternary period (i.e. 2,588 Ma from now until today). The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project phases II and III between 2009 and 2021. The scale varies between 20 000 and 2 500 000.

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.
