Semi-automated mapping of rock in the North Sea 2016


This report describes the results from a semi-automated approach to the mapping of bedrock outcropping at the seabed.


It represents the second phase of this work, following development and initial application of the approach in the Western Channel (CP2 region 3) and Celtic Sea (CP2 region 4) (Diesing et al 2015).

As described previously (Diesing et al 2015), the method consists of two elements, namely:

  1. the automated spatial prediction of the presence and absence of rock at the seabed using a random forest ensemble model, and;

  2. manual editing of the model outputs based on ancillary geological data and expert knowledge.
