Hydrography Will Be Big Contributor Filling the Digital Aquarium

Hydro International Interviews Mathias Jonas, Secretary-General of the International Hydrographic Organisation
The new secretary-general of the International Hydrographic Organisation (IHO), Mathias Jonas, has had a long career, now culminating in the highest rank within the world’s leading organisation for hydrography. He took office this autumn, succeeding Robert Ward, after he was elected in spring this year by the Member States. 'Hydro International' of course wants to know what Dr Jonas envisions for hydrography and the wider world it influences. Mathias Jonas starts off by sharing how he was already in touch with IMO and IHO in the nineties. ‘Arriving at the German maritime administration as a young professional mariner and as one...

Waterside Mapping

Laser scanning and bathymetric side-scan sonar represent the cutting edge of environmental survey technology. Over the last few years, we have tested the integration of these two methodologies, carrying out a number of high-resolution surveys on the Po River, the Venice canals and various Italian harbours. Bathymetric surveys were conducted using a SEA SWATHplus-H wide-swath sonar. An Optech ILRIS-3D terrestrial laser scanner was used to scan the areas above water level. Information from these scans was used to create 3D black and white images (intensity images) of the surveyed area. In the case of the laser scanner, these images are... (read more)

Surveying in the Ross Sea

The deepwater research vessel Tangaroa of the National Institute of Water & Atmospheric Research (NIWA) of New Zealand undertakes regular research expeditions to the Antarctic waters. In the last eight years, this 70m ice-strengthened vessel has successfully completed seven voyages to Antarctica: three of which were to the Ross Sea. This article describes her 48-day voyage in 2006. During this latest voyage, she once again collected data to extend our knowledge of the geophysical and biological make-up of the Ross Sea region Looking Back Tangaroa ’s first voyage to the Ross Sea was in February–March 2001, when it undertook a...

Making European Marine Geospatial Data Available

Hydro International Interviews Jan-Bart Calewaert
For some years now EMODnet has been creating access to marine data sources. The long-term aim of EMODnet is to unlock the wealth of marine observations and data in Europe that are partly hidden and fragmented and make these easily available free of charge. On 20 October 2015, a conference will be organised in Oostende, Belgium, to discuss subjects such as data availability and governance of the EMODnet structure. Hydro International interviews Jan-Bart Calewaert, head of the EMODnet Secretariat. How big is the EMODnet Secretariat? The EMODnet Secretariat was set up in 2013. Currently, there are three people working at... (read more)

Market Prospects for AUVs

This article is based on the results of a new studyThe AUV Gamechanger Report 2008-2017published by Douglas-Westwood Ltd. This report aims to consider the prospects for this game-changing technology and value the future markets for AUV manufacturers to 2017.<P> Un-tethered Autonomous Under­water Vehicles (AUVs) have the potential to change the game in many areas of underwater oper­ations. Long an area of research, AUVs are beginning to show their abilities as cost-effect­ive tools in applications ranging from deep-water survey for the offshore oil and gas industry to military oper­ations. The growing need for many facets of ocean observation also offers great... (read more)

Mariners Need More Current Hydrographic Data

Hydro International Interviews Rear Admiral Christian Andreasen, NOAA (Ret.)
Almost 50 years in hydrography gives you insight and authority to talk about the field and the changes it has gone through in half a century. Rear Admiral Christian Andreasen talks about his career. He is certainly not somebody who only looks back, but is still looking into the future, sharing strong ideas about where hydrography will need to go: ‘Mariners do not understand why hydrographic offices are not more supportive. Finding ways of providing mariners with more current data is an issue.’ Since the 1960s, when you became a hydrographer up to the present, the means and techniques for... (read more)

“Hydrographically Developed Countries Should Reach Out to Developing Countries”

Hydro International Interviews Commodore Min Thein Tint, Commanding Officer of Myanmar Naval Hydrographic Centre, Myanmar Navy
Oriental countries are dedicated to the hydrographic profession but don’t often beat the drums in order to be heard. There’s a lot of work being done, though. One example is Myanmar, a country with several hundreds of kilometres of coastline and many islands as well as inland navigable waters. 'Hydro International' interviewed Commodore Min Thein Tint, Commanding Officer of Myanmar Naval Hydrographic Centre, Myanmar Navy, on capacity building, offshore and inland navigation, data policy and cooperation with the business. How is the MNHC improving its capabilities? Although MNHC became a member of IHO in 2004, the office was founded in 1955... (read more)

2D/3D Web-mapping

Web Visualisation Coastal Orthophotos
This paper describes the development of a web spatial image server used for sharing huge sets of georeferenced coastal orthophotos on the web via an easy visualisation interface. Traditional cartography was considered a highly sophisticated methodology for the production of high-quality maps, using the sales-business model of the non-internet economy and dedicated to specialists. The recent arrival on the scene of three internet leaders whose general mission is to map everything, and the release of their popular online earth browsers has had a huge impact in the geomatics arena. All are by now familiar with the success enjoyed by Google... (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...
