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.

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.

Delineation of 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.

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.

Polylines defining the channel thalweg and / or channel edge of buried or open features. 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.

Areas of relict wetland. Where known the type of wetland is included e.g. salt marsh, tidal flat, peat bog, supra tidal zone, swamp, 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.

Palaeocoastline polyline features delineating former coastlines and shorelines subdivided into those which have been mapped (direct observation) or modelled. 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 accumulation of partially decayed vegetation or organic matter. 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
