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...

  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)

This Is How Airborne Multibeam Lidar Coastal Mapping in Paradise Is Done

Insights from the first commercial use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands. The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands. In July 2018, Fugro embarked on a large-scale project to map the Turks and Caicos Islands for the United Kingdom Hydrographic Office (UKHO). This landmark effort called for integrated, high-resolution bathymetric, topographic and orthoimage data sets to support nautical chart updates and coastal zone management activities. To achieve the sizeable bathymetric portion of... (read more)

Advances in High-speed Underwater Remote Vehicles for Subsea Pipeline Inspection

The Benefits and Challenges of the Technological Revolution in the Pipeline Survey Industry
The pipeline survey industry has undergone a technological revolution in the past couple of years, and the consequential benefits and challenges are only just beginning to be fully realized. The cost efficiency of subsea operations has been one of the key focus areas of the offshore energy industry in recent years. This focus, combined with increased growth in the amount of subsea infrastructure now in-situ on the seafloor, has seen a rising need for innovative approaches to subsea asset inspection. These solutions need to be cost-efficient, maintain data quality, and be able to provide a platform that supports future technologies.... (read more)

GEBCO: the Second Century

Looking towards a general bathymetric chart
The General Bathymetric Chart of the Oceans (GEBCO), the archetype of Ocean Mapping at a world-ocean scale, celebrated its centenary last year with the release of an updated and greatly enhanced Digital Atlas. This CD contains gridded soundings and contours, the culmination of one hundred years of successful blending of hydrography and oceanography. This reflects the creative co-operation of both organisations such as the International Hydrographic Organisation and Intergovernmental Oceanographic Commission and those working side by side at individual level: hydrographers, geologists and geophysicists each contributing their different skills. This major accomplishment also represents the first step into the next... (read more)

GEBCO and Deep Water

Data Assembler, Converter, Interpreter and Disseminator
GEBCO uses deepwater survey data to produce bathymetry maps and grids. Published maps appear complete but are in fact based on very little data. Only a portion of the deep data that could potentially be put to use is contributed to the public domain. All would benefit were more data submitted to data centres. BackgroundWhile the general public thinks that all the seafloor has been mapped and many hydrographers and ocean scientists accept published maps and datasets as faithful representations of the deep-sea floor, in reality only a small percentage of the seafloor has ever been directly measured; estimates range...

Hydrographic Offices and the Commercial World

Interview with Dr Wyn Williams, UK Hydrographer
Hydrographic Offices (HOs) have much more data resting in databases than is used for safety of navigation. This data is increasing required and appreciated for other applications like coastal zone management, private-sector purposes, etc. Meanwhile, in certain countries a policy of ‘retreating government’ leads HOs to (in part) finance their own activities by commercial sale of the data they collect and compile. Another factor forcing HOs to act like private-sector companies is their need for funds to invest in ICT, e.g. for the production of electronic charts. The UK Hydrographic Office (UKHO) provides a good example of these changes, and... (read more)

Port of Barcelona Faces Challenging Growth

Hydro International Interviews Jordy Valls
Under the presidency of Jordi Valls, the Port of Barcelona has continued to expand its operating areas and as a result the volume of maritime traffic calling at the port has also considerably increased. Jordi Valls has been President of the Barcelona Port Authority (APB) since 2006. The Port of Barcelona is the 16th largest port in the world and the largest in the Mediterranean (in number of ships calling per year; the largest in the world being Singapore and the largest in Europe being Rotterdam). Can you tell the readers of Hydro international a little about your background and... (read more)

30 Years of Success

Hydro International Interviews Salem E. Masry
Dr Salem E. Masry, president and chief executive officer of CARIS, accepted to be interviewed by Hydro international on the occasion of the 30th anniversary of his enterprise. Dr Masry, a cake was cut on the occasion of the 30th anniversary of CARIS in its booth during the 4th Extraordinary International Hydrographic Conference in Monaco last June. Can you tell the readers a little about your career and how you had the idea of creating an enterprise that helps hydrographic institutions to manage the data they collect? My interest and work in hydrography started around 1976 when I was working... (read more)
