The excavation of 1m squares down to the geological surface every 100m within sampled areas, regular test-pitting, was at once the most revolutionary and the most generally informative technique introduced by the project, providing a relatively small but very high quality prehistoric ceramic database. The link between test pits and geophysical data was established more firmly by the introduction of targeted test-pitting aimed at key geophysical anomalies at the expense of ploughzone sampling.
