Meet the Hydro International Team at Oceanology International (G-P)

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)

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)

Motion Sensor Performance

Direct Comparison Using 2005 Common Dataset
Integral components of a swathe bathymetry system are the motion and heading sensors. The current trend is to offer a system that combines both components in one package, either as an aided inertial sensor or as two sensors linked by component software. The quality of these inertial sensors has a direct effect on the quality of the final survey. This paper compares five leading available sensors, concluding that they produce markedly differing results. Most surveyors when purchasing or specifying a particular inertial system for a project will base their decision on information generated by the manu-facturers, which often shows all... (read more)

Satellite Navigation

Over the last twenty years Global Positioning System (GPS) receivers have revolutionised navigation. Integrated devices are capable of providing time, position, height, direction, heave and attitude, to accuracy of a few nanoseconds time, 1cm position or 0.01-degree heading. This article explores the future development and implications of Satellite Positioning. Satellite Positioning dominates navigation at sea, in the air and on land and is now available in our cell phones and wristwatches. How it currently works was explored in the October 2006 issue of Hydro international in an article titled ‘Satellite Positioning’ (pp 35-39). But how will it work in the... (read more)

Low-budget Hydrography

Opinions from differing backgrounds
Low-budget Hydrography is the theme of this issue. Realising that different players in hydrography will have differing opinions on various aspects of low-budget hydrography and interested in exploring these divergent views on your behalf, HI asked representatives from various camps for their opinions on some leading questions. The representatives interviewed are: Jeffrey F. Marlow, Survey Technician, US Army Corps of Engineers CDR Guy Noll, Commanding Officer, NOAA Ship RAINIER LTCDR Richard Cullen, Staff Officer Quality Control AHS Questions: 1. Can you briefly explain your position in the hydrographic world: your experience and present position? Cullen: I have been employed by... (read more)

Fugro's CEO: “Working for a Safer and More Sustainable World”

Interview with Mark Heine
Mark Heine is chairman of the board and CEO of Fugro, with the headquarters in the Netherlands. Fugro is the leading and largest specialised survey company in the world, serving the full lifecycle of assets, and calls itself a Geo-data specialist. For the avid mountaineer Heine, challenges are never too high to take on, not even heading up a multinational in transition, from a company largely dependent on the oil and gas industry to one that wants to co-create a sustainable and liveable world. We talked to Mark Heine about leadership style, strategies for finding new employees, and Seabed 2030. About this ambitious project, Heine says ‘Commercial companies need to work together with NGOs and academia to make this happen.’ Mark Heine is chairman of the board and CEO of Fugro, which is headquartered in the Netherlands.

Sea Level Rise Modelling

In a Caribbean Small Island Developing State
In 2009, a research project was implemented to study the potential socio-economic impacts of climate change upon coastal communities in Canada and the Caribbean. Grande Riviere in Trinidad and Tobago, one of the study sites, is an important nesting site for leatherback turtles. Turtle watching, part of eco-tourism conducted in that part of the country, is an important source of income for the community. Any significant rise in mean sea level may negatively impact the turtles’ nesting sites and consequently negatively impact Grande Riviere’s socio-economic wellbeing. Hydrographic and topographic surveying techniques and GIS were used to construct spatial models that... (read more)

Ocean Survey - The World Market

Over the past thirteen years Douglas-Westwood Limited has produced a series of occasional techno-economic studies of the Ocean Survey industry. This latest, The World Ocean Survey Report 2004-2008 aims to review the most significant recent developments, value markets and provide a forecast for the period 2004 to 2008. In practice, it is very difficult to precisely define the boundaries of the subject of ocean survey as for example some definitions may include survey of the major navigable waterways. Furthermore, commercial survey & positioning (S&P) contractors’ activities range into other areas, including the operation of assets in non-survey tasks, such as... (read more)

The XVIII International Hydrographic Conference

The Conference was held in the main hall of the Auditorium Ranier III in Monaco from 23 to 27 April 2012 which had been conceded to the IHB by the Government of the Principality. In that same building were put in place two exhibitions: the IHO Member States (IHO MS) cartographic exhibition (27 exhibitors) and the Hydrographic Industry Exhibition (27 Exhibitors including UKHO). Responding to the invitation of the IHB, the following MS sent their research vessels: China (RV Qian Sanqiang), Russia (RV Donuzlav), Spain (RV Tofiño) and the United States (RV Bruce Heezen). France sent the Frigate La Fayette.... (read more)

Wideband Signals the Future for Acoustic Positioning

The high accuracy and availability of GPS has enabled the offshore survey community to deliver benefits to customers and fuelled demand for a corresponding improvement in subsea acoustic positioning systems. This paper describes the benefits of Sonardyne International’s implementation of the same Wideband signal processing techniques that are used in GPS and discusses the fundamental difference between GPS measurement processes and acoustic positioning systems. Narrowband Limitations Until recently the majority of acoustic positioning systems used narrowband toneburst signals and analogue signal processing methods which have suffered from weaknesses: a limited number of operating channels, susceptibility to noise and interference, and...
