Looking Far beyond the Horizon

Hydro International Interviews Steven Xu, CEO, Hi-Target
These are exciting times in the geomatics and hydrographic industry. Innovative solutions are being developed, integration is the main keyword and the big players are acquiring smaller companies that add a new dimension to their portfolio. Europe, Japan and North America are traditional strongholds of geomatics, but several very ambitious companies from China are doing their utmost to catch up with the frontrunners. Steven Xu, CEO of Hi-Target, was more than happy to share his thoughts and expectations with Hydro International. Read the interview here. Wim van Wegen and Joost Boers, Geomares Publishing, The Netherlands Hi-Target was established in Guangzhou,... (read more)

AUV Operations in Marine Mining

DBM GEOSURVEY is the marine survey arm of De Beers Marine, the world’s largest marine precious mineral mining company. DBM GEOSURVEY has pioneered the development of geophysical survey systems over the past 20 years to improve mineral resource development and support DBM’s mining activities. Core to this development was the decision to adopt autonomous underwater vehicles (AUVs) as the primary survey platform. We look back on the challenges and successes of 7 years of AUV operations.<P> One of the key factors crucial to the success in offshore diamond mining and exploration operations is the ability to improve geological understanding of...

Technology for Hydrographic Purposes

Interview with Erik Hammerstad, Kongsberg Maritime AS
Hardware (and to a lesser extent software) for the hydrographic survey industry is mostly developed by technical experts not educated as hydrographic surveyors. Nevertheless, manufacturers have come up with equipment that has broadened and hugely opened up the possibilities for hydrographic and oceanographic investigations. What is the link between hydrography, which still very much depends on field experience, and technological developments? Or how is technology directed towards the invention of usable and workable equipment for hydrography? Hydro international interviewed Erik Hammerstad, Senior Principal Engineer /Hydrography Subsea of Kongsberg Maritime AS Norway. Please tell our readers something of your professional education...

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)

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)

Satellite Derived Bathymetry Migration

From Laboratories to Chart Production Routine
Much has been said about Satellite Derived Bathymetry (SDB), but with the exception of SHOM, which led to the introduction of a number of SDB charts into the French chart series, next to nothing has been implemented within the international hydrographic community. This article aims to update readers as SDB, thanks to new generation satellites and modelling, seeing the light after going through a thirty years’ tunnel. In 2014, detailed tests and analysis conducted by government hydrographers, cartographers and recognised satellite scientists operating for a number of projects initiated by the European Space Agency, the WWF and other stakeholders, were completed,...
