Oceanology International 2010 Preview (1)

Oceanology International, the world's premier event for the marine science and ocean technology community, will this year be held in London, UK, from 9th to 11th March. Over 6,600 attendees are expected to drop in on this event, visiting the world largest exhibition with over 500 suppliers, the associated biennial conference, or are attracted by the many vessels and networking opportunities. This preview aims to give a foretaste of this year's exhibition that is the largest ever held, with pavilions from Canada, France, Germany, Ireland, The Netherlands and individual exhibitors from nearly 30 countries. We invited exhibitors to introduce themselves... (read more)

A New Era for the IFHS?

Hydro international interviews Paul Hornsby, chairman of IFHS
In July last year Paul Hornsby, President of the Australasian Hydrographic Society (AHS), became Chairman of Council of The Hydrographic Society (THS). On 2 November last year, during HYDRO 4, the representatives of five National Hydrographic Societies signed a resolution with which the Memorandum and Articles of Association of the new Federation were endorsed. By doing so THS ceased to exist and IFHS came into force. Will the ambitious new chairman develop a new course for IFHS? Paul Hornsby agreed to be interviewed on his plans. At HYDRO 4 you stated, that you are a customer rather than a hydrographer.... (read more)

Proliferation SeaSonde Coastal Current-Mapping Radars

HF interference to improve coverage performance
For several decades while coastal HF current-mapping radars were under development, they radiated rarely and only for a few weeks at a time. Now 120 commercial SeaSonde units have been sold and seventy operate continuously in permanent locations. Their numbers are presently increasing at a rate of about 35 per year and they are used for a variety of maritime purposes. Although emitting only 50 watts of power they can map currents to 200km on the lower frequencies; these signals may also travel half way around the world, thanks to overhead reflecting ionospheric layers. After all, these same layers have... (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...

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)

Altitude and Dynamic Error in TPE and CUBE

Total Propagated Error (TPE) and Combined Uncertainty Bathymetric Estimator (CUBE) help automate data cleaning and filtering. This paper discusses the effect of using altitude in place of heave for survey data processing and that of using error estimates in TPE and CUBE for both variables. Final hydrographic data quality is examined. Total Propagated Error (TPE) and Combined Uncertainty Bathymetric Estimator (CUBE) are designed for use with hydrographic survey data to minimise subjective user intervention and help automate data cleaning and filtering. With the trend in hydrographic surveying towards objective estimation of data quality, these methods rely heavily on error estimates... (read more)

The Dutch Sector of the North Sea

A geological introduction
The North Sea directorate of the Ministry of Public Works and the department of Geo-Marine & Coast of The Netherlands Institute of Applied Geoscience-TNO jointly carried out a geological mapping programme and the assessment of industrial sand deposits in the Dutch sector of the North Sea. A brief outline of the methods used and the knowledge obtained is given. The Dutch part of the North Sea (NCP) occupies an area of 57,000 km2 which is larger than the mainland of The Netherlands (Figure 1). In addition to traditional activities, like fishery and shipping, since the 1960s there have been new... (read more)

Do We Order a Ticket for New Orleans?

Spearhead is again organising an Oceanology International (OI), one of the more successful conferences and exhibition events. The 2003 event is to be held in New Orleans, USA - one more in the row of OI Americas. This year the circumstances with regard to the world economy and the international political and health situation are not normal and may offer constraints on the wish to participate. By tradition, every OI Special issue of Hydro international includes a multi-interview with representatives of the world hydrographic community. For our present issue we asked them to give us their views on OI America... (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)

Hydrography in China

Hydro International interviews Professor and Commodore Liu Yanchun, P.R. China
China has more than 900 lakes, some 5,800 rivers, of which five are very large, an 18,000km-long coastline and more than 6,000 islands in about 3.50 million square kilometres of sea area. All of this has to be surveyed and charted under the jurisdiction of the Chinese government. Ports are expanding rapidly and new ports are being built, also requiring an enormous hydrographic surveying effort. How is China doing this? What are the roles and responsibilities of the Maritime Safety Administration, the Chinese Navy, port authorities and surveying companies? We asked the head of the Department of Hydrography and Cartography... (read more)
