GLONASS, GPS and GALILEO Present and Future Aspects

Global Navigation and Hydrography is the theme of this issue. GALILEO has received a ‘green light’, GPS has planned some important improvements and GLONASS has entered on a significant development programme. Time for HI to ask experts involved in each GNSS for their opinion on certain topics and finally to put the question: ‘What is in it all for us surveyors?’ The experts interviewed are: Dr Vidal Ashkenazi (GALILEO), Dr Keith McDonald (GPS) and Dr Boris Shebshaevich (GLONASS). The planned GALILEO-system involves some discussion in connection with already present GNSS systems and some of our questions had a political aspect.... (read more)

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)

Excited by Automation Driven by Autonomous Vehicles

Hydro International Interviews Capt. Shep Smith
NOAA is one of the bigger organisations in the world that has surveying and charting in its portfolio. It’s an immense task as the USA has about 95,000 miles of coastline, important ports and a wide range of users – from recreational boaters to the biggest container vessels and tankers. The country also has to deal with environmental disasters like hurricanes and oil spills. NOAA is undergoing changes as the chart portfolio is ‘going digital’ and new initiatives such as using Maritime Autonomous Systems (MAS) for surveys. Hydro International interviews Capt Shep Smith, who generously gave an insight behind the scenes.

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)

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...

Subsea Cable Route Surveying

Planning Challenges
Almost all (99%) international data is transmitted by around 265 subsea cable systems connecting the world. The total length of subsea cables exceeds 1.6 million kilometres, and they can be found as deep as 8,000m. The cables, which can cost hundreds of millions of dollars, must generally be run across flat surfaces of the ocean floor, taking care to avoid coral reefs, wrecks, environmentally and politically sensitive areas and general geological obstructions. Diameters are generally no thicker than an average garden hose. Cable laying is an expensive operation and is a function of the total length of cable, water depths... (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)
