Map of Varne_Hastings broadscale

Broadscale interpretation of Seabed facies between Hastings and Dungeness (varne) in Eastern Channel. Survey was 50 km (E) x 15 km (N). Individual side scan tracks interpreted into Seabed sediments, then interpolated across whole survey area by Sally Philpott (BGS Keyworth). This data set relates to side scan tracks at 1 km track spacing, 400 m swathe width. The data has limited ground-truthing, and biotopes have not been assigned. Faunal samples from Hammon Grabs and 2 m beam trawls exist, but have not been used to interpret biotopes. PSA data in half phi units now converted to people. The area contains the smaller, more detailed map of Hastings shingle bank, in Facies map of Hastings (GB000455). This work is part of project AE1033 (internal CEFAS code) to be reported in CEFAS Science Series Technical Report, Summer 2005. The polygons follow the BGS sediment/bedform classification.
