The aggregate deposits presented here comprise near-shore deposits of non-metallic detrital minerals and calcium carbonate. They occur both on beaches and deeper seabed areas. Marine aggregate deposits are principally extracted for use in the construction industry. Concentrated into their present occurrences by hydrodynamic processes, aggregates may have originally been deposited by mechanis...

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: Reason...

Channel landscape features subdivided where possible into open tunnel valley, open fluvial channel, open tidal channel, tidal inlet, buried fluvial channel, buried tunnel valley, or buried tidal channel. 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...

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 provi...

Coastal and submarine springs subdivided as:1. Coastal; 2. Submarine; 3. Other.Where information on the genesis of the feature is available that is also given e.g. geological fault (FEA_GEN_TY). The rate of flow in m3 / second is specified if 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 p...

The shoreline is a highly dynamic land-sea interface that provides important services such as ecology, floodprotection and recreation. It is constantly modified by wind, waves and tides, and impacted by human activity.Hence, the decadal change of shorelines reflect natural processes as well as human influence, whether positiveor negative. Climatic-driven changes such as sea level rise, higher wave...
