1997-2007: A Decade of Developments in Hydrography

We all know what is the oldest profession in the world. The second oldest is probably that of land surveyor: Adam undoubtedly wanted to stake out the boundaries of paradise in order to know what was and was not his. Paradise, or the Garden of Eden, was to be found in the land of the Euphrates and Tigris, where these two rivers converge at the town of Qurna in the present Shatt al Arab. And apart from his topographical activities Adam must also have made some hydrographic observations, probably just using a stick cut from a local fruit tree! After... (read more)

Sea Levels and the Coast

The oceans are a central part of the global climate system. As Roger Revelle, one of the early directors of the Scripps Institute of Oceanography, said, “The oceans exert a profound influence on mankind and indeed upon all forms of life on Earth. The oceans are inexhaustible sources of water and heat, and control the climate of many parts of the world.” He also recognised that “human beings are now carrying out a large-scale geophysical experiment of a kind that could have not have happened in the past nor be reproduced in the future”. Roger Revelle’s thoughts have even more... (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)

“Developing by Leaps and Bounds”

Hydro international Interviews Shou Shunbao, Manager, Da Hua Hydrographic Surveying Company, Shangha
It may look as though Europe, the USA and Canada, followed by Australasia, dominate the hydrographic world scene. But there must also be enormous potential in the area north of the Far East: Vietnam, China, Japan, etc. In particular, the economy in China is growing fast and, with her long coastline and dependence upon shipping, China must see a considerable amount of hydrographic work. Hydro INTERNATIONAL interviewed Mr Shou Shunbao, manager with Da Hua Hydrographic Surveying Company of Shanghai, to obtain more information on hydrographic activities in the area. Shou Shunbao, born in November 1955, graduated from Nanjing College of... (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)

Exploring Coral Reef Sustainability

The Island of Bonaire in the Southwest Caribbean, a Marine Protected Area since 1979, has one of the most pristine coral reefs in the region. The last synoptic survey of the leeward coast was by the Dutch scientist Dr Fleur van Duyl in the 1980s and parts of the deeper reef have never been mapped. In January 2008, the US National Oceanic and Atmospheric Administration (NOAA) funded a unique expedition to Bonaire, deploying three compact Autonomous Underwater Vehicles (AUVs) carrying various oceanographic instrumentation packages and a swath bathymetry sonar.<p> The crystal-clear watersand schools of reef fish made an enchanting setting...

Acquiring and Integrating Bathymetric Lidar

Developing a Seamless Coastal DEM from Topographic and Bathymetric LiDAR Data
We investigated the most significant issues affecting the creation of a littoral zone digital elevation model from overlapping bathymetric and topographic Lidar (light detection and ranging) data. The main challenge was found to be the use of different methodologies used to establish vertical datums, as well as the narrow overlap between the two data sets, lack of ground control points and data gaps. We identified the main causes of gaps in bathymetric Lidar data and outline a new procedure for quantifying their occurrence. The Cooperative Research Centre for Spatial Information in Australia has been collaborating with the Victorian Department of... (read more)

Uncovering the Mysteries of the Oceans

What is Oceanography and How to Become an Oceanographer
This article will dig into the field of Oceanography and the trends and methods developed over the past decades. Did you know that marine species compound more than 80% of the Earth’s biodiversity? Or that seaweed and other sea plants living in the ocean produce around 50% of the oxygen in the atmosphere? With this in mind, many efforts are now concentrated on studies of the ocean, such as identification of those beneficial to ocean resources and organisms that can be used as medicines for many critical ailments. Within this article, you will also get familiar with terms like biomimicry,... (read more)

‘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)

Enhancing Port and Harbour Security with Unmanned Surface Vehicles

As readers of Hydro International know, the world’s ports and harbours are crucial to global trade. From Singapore to Antwerp, to Shanghai, to Rotterdam, to Los Angeles to other mega-ports and hundreds of other smaller ports, these crucial nodes are critical to world trade. A disaster like a fire, explosion, or a major oil spill could close one of these ports for an indefinite time. The secondary effects of such a catastrophe could include releasing a huge amount of pollution into rivers and oceans.
