British Geological Survey (BGS) Geophysical Survey 1999/3: Coastal and Estuary Evolution (25/10/1999 to 29/10/1999)

This British Geological Survey (BGS) marine geophysical survey took place in October 1999 in the Mersey Estuary aboard the Environment Agency vessel Goastal Guardian. The purpose was to gather data which could be used in Coastal and Estuary Evolution studies. Sea-floor data were collected using an echosounder and a sidescan sonar. Subsurface seismic data were gathered using a surface tow boomer. These data are archived by BGS. Technical details of the survey are contained in BGS report WB/00/02.
