Much More Than a Typical Hydrographic Office

Hydro International Interviews Capt Brian Connon, Director NGA Marine Safety Office
In October 2015, Capt Brian D. Connon assumed the role of director of the National Geospatial-Intelligence Agency’s Maritime Safety Office. The organisation is an important, although not always visible, link in the global maritime safety chain. Its work contributes to generic marine safety and, due to the nature of the data collected and analysed, its role is especially relevant for security, humanitarian assistance and disaster relief. In this interview with Hydro International, Capt Brian Connon lays out the role of hydrographic data and technologies in the NGA. Can you briefly outline the work of the NGA? The National Geospatial-Intelligence Agency (NGA) is the United States’ primary... (read more)

Bering Sea ASV Force Multiplier

Arctic Hydrographic Survey Achieves Production Gains by Utilising ASV Technology
TerraSond, a hydrographic services company based in Palmer, Alaska (USA), used a C-Worker 5 (CW5) unmanned autonomous surface vessel (ASV) in conjunction with a 105’ (32m) research vessel from June through August 2016 on a major hydrographic survey in the Bering Sea region of Alaska. The ASV served as a force-multiplier, collecting multibeam and towed sidescan data alongside the larger vessel, which surveyed adjacent lines simultaneously. The 18’ (5.5m) ASV collected 2,275 nautical line miles (4,213km) – 44% of the project total – and achieved an industry first in terms of data production rates utilising ASV technology in the Arctic....

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)

The Future of ECDIS

After a gap of five years, the 2nd ECDIS Conference took place in Singapore in October 2003. At first glance everything was as before: the venue of the conference, its organisers, the lecturers and companies involved, and Ð strangely enough Ð even many of the titles of the presentations. But the most important item had changed and this was the mood in which the topic was presented. Five years ago almost everybody agreed that we were about to see a great breakthrough in the ambitious IMO/IHO ECDIS venture. This time, a gloomy mood of resignation and frustration seems to have...

LIDAR Bathymetry in Norwegian Waters

The Norwegian Hydrographic Service (NHS) has and will be utilising airborne LIDAR bathymetry in connection with the ongoing effort to modernise the maritime infrastructure along the Norwegian coast. This article describes the benefits and limitations of the technology, the results of a pilot project conducted in Norwegian waters in 1998 and operational data collection in Norway in 2002. The long-term plan for the Norwegian Hydrographic Service (NHS) is by 2006 to have the Norwegian coast covered with ENCs and paper charts based on source data from modern surveys. The Enhanced ENC Project was established in 1999 and is responsible for... (read more)

Evolution in Nautical Charting

Toward Convergence of Paradigms
For all their difficulty to learn, implement, fix, re-learn, and keep trying to fix, data standards have become essential to many aspects of our modern world. For almost 90 years, the International Hydrographic Organization (IHO) has provided international standards for nautical charting and hydrography. This in itself was a paradigm shift compared with previous centuries of ocean navigation, in which nautical charts were carefully guarded as state and industry secrets. The next great paradigm shift began when the IHO’s S-57 Transfer Standard for Digital Hydrographic Data was introduced in 1992 to enable nautical chart data to be transferred digitally and...

Societies

  Australasian Hydrographic Society   East Australia Region It is noteworthy to record that a present member of the East Australia Region (EAR)/AHS and past Hydrographer of the Royal Australian Navy (RAN) is now engaged in large-scale maritime security operations in the Persian Gulf. As Task Force 158 Commander, Commodore Bruce Kafer RAN now has the responsibility – in addition to other aspects of his mission – of ensuring the security of ships, personnel and equipment engaged in large-scale energy infrastructure development work in the Northern Arabian Gulf. These operations will extend well into 2010. Informed sources put the value... (read more)

Educational Institutes Need to Reach Out in Co-operation

Hydro international Interviews Nicolas Seube
Brest is the biggest supplier of highly qualified hydrographers in Europe with more than 30 graduates per year and growing. Can you explain the success of ENSTA? The success of ENSTA has several components. Our institute is a Grande Ecole, which means that students must take a National competitive exam in order to get in, or go through a selective file examination after a BSc or a first year of MSc. This ensures us of high level students. Our curriculum contains difficult scientific components, applied mathematics, physics and information technologies to ensure that students obtain a thorough understanding of the... (read more)

Bathymetric Data Management for the Future

The Canadian Hydrographic Service (CHS) is involved in the definition and experimentation with S-100, the next standard for high-definition bathymetry. This new standard will enable hydrographic offices to deliver bathymetry to a level of detail never seen before. Implementing the standard into production will pose many challenges for data producers. Those high-definition bathymetry files need to be created, distributed and updated. New technologies and processes must be adopted and refined, and many critical issues must be resolved to ensure maximum production efficiency.<P> The mandate of the CHS is tomaintain a portfolio of navigation charts and provide water level information all...

Technology in Focus: Multi-beam Echosounders

New Technology, New Capabilities and New Markets
The evolution of multi-beam echo sounders (MBES) is leading to systems with enhanced capabilities in their traditional markets, but also provides features to allow the expansion of their use into new areas and applications. This short review highlights some of the features of the latest generation of systems. The attributes of an MBES system are traditionally described by technical specifications, such as operating frequency, pulse length, beamwidth, number of beams and coverage. These technical parameters define the nature of the system, but the fundamental characteristics of greatest interest. By Dave Mann, Gardline Geosurvey, UK. Just as technological advances mean there... (read more)
