Magnetometer survey with a cart-mounted array of Bartington Grad-01-1000L fluxgate gradiometers. The survey identified a few possible ditches of uncertain date, although these are difficult to discern amidst an abundance of channels and creeks in the underlying tidal flat deposits. A set of historic field boundaries and a series of field drains were also detected.
Walford et al. (Wed,) studied this question.
