A Targa 31 work boat – towing a gradiometer, side-scan sonar and sub-bottom profiler – surveyed the river bed near Hungerford Bridge as well as close to MI6 headquarters at Vauxhall Bridge.

Both areas surveyed are among the sites expected to be used by the water company during the construction of its 'super sewer' tunnel under the river.

A decade ago a World War II shell was found by a dredger near Hungerford Bridge.
