Coastal Landforms - polygons

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.
