Great Yarmouth based marine site investigation company Coastal Geosciences' now offers a hovercraft based surveying service, which can greatly cut survey times over soft ground and in difficult tidal areas. The craft is positioned by real time kinematic GPS, which records height relative to a chosen data. An over-the-side echosounder provides bathymetric information and the craft can also be used to deploy magnetometers, sidescan and other near surface seismics.
