It is not as detailed as the scans <em>Magpie <\/em>or other Royal Navy survey vessels can produce with their high-tech sonar suites, and it only works close to shore.<\/p>\n<p>But the method &ndash; known as radar bathymetry and developed by scientists from the National Oceanography Centre in Liverpool and MOD experts from Defence Science and Technology Laboratory &ndash; could be vital in times of peace or war when time is critical.<\/p>\n<p>&ldquo;By analyzing the sea clutter images of waves visible on standard marine radars a bathymetric profile (that&#039;s the depth) and surface current assessment is created,&rdquo; explained the lead project scientist at the National Oceanography Centre, Paul Bell. &ldquo;This technique could allow the remote charting of both shallow water and currents from a standoff distance of several nautical miles and could be employed by all Royal Navy Ships using the navigation radars that are already fitted with.&rdquo;<\/p>\n<p>Given her small size, <em>Magpie <\/em>doesn&rsquo;t carry the standard navigational radar used by the rest of the Royal Navy&#039;s fleet, so one was temporarily installed on a roof rack.<\/p>\n<p><img decoding=\"async\" alt=\"\" src=\"https:\/\/eolog.com\/wp-content\/uploads\/2021\/03\/Royal-Navy-Tests-Software-for-Radar-Based-Bathymetric-Survey.jpg\" style=\"height:400px;width:600px\" \/><\/p>\n<p><em>HMS Magpie off Portsmouth (Royal Navy)<\/em><\/p>\n<p>It would take the ship perhaps a fortnight to map the ocean floor on the approaches to Plymouth naval base and the Sound with her sonar.
