UK-based marine survey and environmental consultancy Furgo EMU has completed a two-year nautical charting survey, collecting over 15 billion bathymetric soundings for the 2011 to 2013 Maritime Coastguard Agency (MCA) Civil Hydrography Programme.
Working in UK coastal waters between the 2m and 40m contours, Furgo used eight vessels to survey more than 3,000km² of seabed off the English, Welsh, Scottish and Northern Irish coastlines.
Some of the areas surveyed by Furgo were last searched in the 19th century, while many in Scottish coastal waters had never previously been surveyed.
The company has collected high-resolution seabed data, including the discovery of several previously uncharted wrecks and the re-classification of water depths over some existing wrecks.
Furgo acquired its last Reson and Kongsberg dual-head multibeam echosounders and associated positioning and orientation systems on 25 September.
The company also deployed the systems to meet the International Hydrographic Organisation Order 1a standards and supplied FIG/IHO Cat A accredited hydrographic surveyors for the project.
The collected data, which is made public by MCA and the UKHO, is being used by the government to support marine spatial planning and maritime decision-making.
Fugro EMU plans to continue its work on similar projects using the latest equipment and the expertise of their hydrographers.
