Oceanology International 2010 Preview (2)

This is the continuation of the Oceanology International Preview. For companies A - L, see part 1  MacArtney Underwater Technology Group MacArtney will be introducing their newest innovation in multiplexers - the NEXUS MK E electrical multiplexer, which is designed to the same high standards as the fibre optic multiplexer range with the telemetry part of the multiplexer adapted to non-fibre optic cables. Another highlight will be the demonstration of a working active heave compensation winch, the Cormac 3 Stainless Steel winch. It will demonstrate load stability during vessel movement on the sea. MacArtney will show their Focus ROTV, camera... (read more)

Meet the Hydro International Team at Oceanology International (R-Y)

In the third week of March, the entire marine world will be gathering in London, as this is where the biannual Oceanology International event is taking place. The exhibition and the conference bring together technological and scientific developments. With over 550 exhibitors and a state of the art conference programme OI12 is definitely the place to be. OI12 will be held from 13 to 15 March at the ExCel Exhibition and Conference Centre in Londonfs Docklands. The organisers are expecting at least 7,000 visitors to attend. Hydro international will of course be present. We not only have a stand (No.... (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)

Danish Hydrographic Office Turns to GIS for Automated Maritime Charting

A Radical Update Was Needed
Denmark has challenging seascapes to map and chart. It has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for Greenland were created in the 1960s. When GPS started to gain prominence, a radical update was needed. Apart from its 42-mile land border with Germany, the peninsular country of Denmark, with its scores of bays, straits, and fjords,  is surrounded almost entirely by the North and Baltic Seas. Denmark is also composed of more than 400 islands, including the Faroe Islands, located in the Atlantic Ocean between the United Kingdom... (read more)

The Advancing Technology of AUVs

A View of the Autonomous Underwater Vehicle Market
Since the last autonomous underwater vehicle (AUV) review in 2016, the market has continued to grow. The biggest market for AUV systems remains the military. The world’s most advanced Navies own and operate low-logistic AUV systems for mine countermeasures (MCM) in very shallow waters. These systems can operate in confined areas where MCM vessels cannot. The same systems can also be used in search and recovery operations, hydrography and salvage. This market used to be dominated by a handful of AUV providers. However, the number of manufacturers is increasing. Defence primes are also investing in these technologies through internal development... (read more)

PPVRS Rushes in a New Era for Hydrographic Surveying

This paper describes a technique for centimetric positioning in hydrographic surveying using a network of GPS base stations to determine ephemeris, clock and atmospheric errors at the rover location. This technique uses the GPS observations from a Virtual Reference Station to compute a tightly integrated GPS/Inertial solution, with minimum baselines of over 100km.<P> Today’s primary positioningtechnique for near-shore (within 100km) marine hydrography is based on the integration of GPS and inertial navigation systems (INS). The inertial measurement unit (IMU) aids in reducing GPS noise as well as providing high-bandwidth uninterrupted solutions during GPS outages. For high-precision surveys (5cm or better... (read more)

The Importance of Continuous Education

How Fugro Academy Advances the Company’s Business
It is now well over ten years since Fugro Academy opened its doors within Fugro as a focal point for learning and development for the company’s 10,000-plus employees, who specialise in providing geoinformation and asset integrity services to a global client base. So, what is Fugro Academy and how does it contribute to the ongoing education and professional development of the largely technical workforce? Andrew McNeill, global talent development manager at Fugro, explains more. Fugro Academy was established in late 2006. Around that time, Fugro was working in a very buoyant market, particularly for services related to oil and gas,... (read more)

What is the Manufacturer’s view?

Interview with Steve Berglund, President and CEO, Trimble
In the previous series of interviews, Hydro international has paid much attention to conferences, standards of competence, survey companies, etc. Aiming at the total filed of hydrography we also wish to pay attention to the section of developers and manufacturers of equipment. Steve Berglund, CEO of Trimble, an internationally known manufacturers of hydrographic equipment and thus a representative example, agreed to be interviewed and disclose some insight information from that part of the hydrographic scene. Please give our readers a summary of your education, career development and your involvement in hydrography (if any) Steven W. Berglund joined Trimble as President... (read more)

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...

Shallow Survey 2003

Interview with Dr Phil Chapple, Scientist, Conference Convenor, Australia
After completing a Bachelor of Science with Honours in Physics in 1983, Dr Phil Chapple worked in a laboratory of the Australian Defence Science & Technology Organisation (DSTO) where lasers were being developed for Australia’s Laser Airborne Depth Sounder (LADS). He returned to university to study for a PhD in Physics (laser spectroscopy), returned again to DSTO to investigate laser-material interactions and later worked some years on statistical image processing techniques. He completed the degree of Master of Mathematical Sciences (Signal & Information Processing), meanwhile learning details of sonar signal processing. In 1999 he moved to the DSTO Maritime Operations... (read more)
