Improving Overall Resolution of Bathymetric Survey

Integrated Use of Multi-beam Echo Sounder and Towed Interferometric Sonar
Designing offshore engineering facilities requires large amounts of information. To acquire it, suites of engineering and geophysical surveys are run, which as a rule include such techniques of seabed and sub-bottom investigation as seismic profiling, acoustic, magnetic and bathymetric surveys. Obtaining accurate and detailed seabed bathymetry is extremely important because the quality of other surveys depends on the quality of the bathymetry. One of the most accurate and cost-effective ways to acquire high-resolution bathymetric data is the use of shipborne bathymetric systems such as multi-beam echo sounders (MBES) or interferometers. The drawback of this method is that the resolution of... (read more)

Hydrography in the Far East

Interview with Associate Prof. Dr Mohd Razali Mahmud
There is much current activity on the hydrographic scene in the Far East region; the area was hit by the Tsunami, 26th December 2004. The region is also on the doorstep of China, a country undergoing enormous economic growth and a consequent growing market for hydrographic surveying. Have developments in China any other consequences for the hydrographic community in the Far East? Associate Professor Dr Mohd Razali Mahmud, Head of Hydrography, Institute for Geospatial Science and Technology of the Universiti Teknologi Malaysia (UTM) agreed to be interviewed by Hydro international (HI) on the matter. Please give our readers a summary... (read more)

Unravelling the Ridge and Rift

Missed Opportunities and Triumph
Following Maurice Ewing’s first cruise to the Mid-Atlantic Ridge, two more were made by the end of the 1940s. The first of these was led by Ewing while the second was led by Bruce Heezen. Although Gunter Dietrich’s paper was referred to in the 1949 paper by Ivan Tolstoy and Ewing (see part I in last issue), neither seems to have comprehended its significance as he reported in the November 1949 National Geographic magazine: “Crossing the ridge, we drew a detailed profile of its peaks with our fathometer. Flanking the central highlands, we found deep trenches separating the main Ridge... (read more)

Paperless Navigation – Better Now Than Later

On the Way to Cost Savings and Safer Navigation
With the introduction of the amendments to SOLAS regulation V/19 making the carriage of Electronic Chart Display and Information Systems (ECDIS) under SOLAS chapter V Safety of Navigation mandatory, as proposed by NAV 54, the BIG question now is how and when to implement the ECDIS and ’Paperless Navigation’ on board vessels. Waiting until the last applicable dates may seem to be an obvious choice but obvious choice is not always the best choice. Paperless navigation has proven to save costs (eventually), enhance safety on board and attract quality manpower. Can such factors definitely offset the cost of implementation? The... (read more)

UKHO Acquires SevenCs

HI Interviews Dr Wyn Williams, UKHO and Gert Büttgenbach, SevenCs
More and more public institutions are involving themselves in private enterprise (see interview ‘The Public-private Dilemma’, December 2005). Is the line between public and private activities becoming blurred? The UK Hydrographic Office has just announced its aquisition of SevenCs, a German producer of ENC production tools and ECDIS.ECS systems (see this month’s Market Place). Hydro international was eager to learn of the thinking behind the move and future plans. We were fortunate, at short notice, to interview UKHO Chief Executive Dr Wyn Williams and co-founder and executive director of SevenCs, Gert Büttgenbach. The press release on the acquisition of SevenCs... (read more)

The XVIII International Hydrographic Conference

The Conference was held in the main hall of the Auditorium Ranier III in Monaco from 23 to 27 April 2012 which had been conceded to the IHB by the Government of the Principality. In that same building were put in place two exhibitions: the IHO Member States (IHO MS) cartographic exhibition (27 exhibitors) and the Hydrographic Industry Exhibition (27 Exhibitors including UKHO). Responding to the invitation of the IHB, the following MS sent their research vessels: China (RV Qian Sanqiang), Russia (RV Donuzlav), Spain (RV Tofiño) and the United States (RV Bruce Heezen). France sent the Frigate La Fayette.... (read more)

Small Boat Work – Dangerous Then, Dangerous Today

The ability to conduct inshore hydrographic surveys has always been dependent on small boats and the seamanship of those conducting the surveys. Besides the obvious use of small boats for the acquisition of soundings and their accompanying positions, it was not so long ago that many surveys of remote and open coastlines also had to transport topographic and geodetic survey crews to shore camps or daily work areas. Although the nature of both shore work and hydrographic work has changed somewhat over the years, small boat work with its attendant dangers has remained a constant. Before the days of radio...

‘Hydrography is Both a Science and a Technique’

7 Questions to the New Director General of the French Hydrographic Office
Chief weapons engineer Laurent Kerléguer was appointed director general of Shom, the French hydrographic office, in July 2019. In this interview, Hydro International asks him about the latest developments regarding the world of hydrography, climate change and artificial intelligence. “It’s becoming more urgent than ever to measure the ocean.” Chief weapons engineer Laurent Kerléguer was appointed director-general of Shom, the French hydrographic office, in July 2019. In this interview, Hydro International asks him about the latest developments regarding the world of hydrography, climate change and artificial intelligence. “It’s becoming more urgent than ever to measure the ocean.” Laurent Kerléguer was born in Brest, France, and has always lived by – or close to – the sea. Although he never had a ‘dream job’ as a child, he always had the feeling that his career would be linked to the sea. “For me as an engineer, hydrography is the perfect... (read more)
