Measuring Small Changes in a Big Way
Coastal wetlands are special places where the sea infuses the shore, creating an environment supportive of abundant plant and animal life. They are also fragile places, where a small change in the bal...

‘A legal requirement to carry adequate nautical charts and books is found in both the International Maritime Organization (IMO), the Safety of Life at Sea (SOLAS) and national regulations, so marine...
Less than 30,000km of seismic profile exist for the Arctic Ocean. Components of a new autonomous drifting seismic buoy have now been successfully tested using the hovercraftR/H Sabvabaa. Three buoys w...
The requirements for hydrographic surveys influence the specifications adopted. Requirements, however, are not static. For example, emerging requirements now include collecting hydrographic data for t...
Since 2001, hydrographic survey-based studies have been growing in size, complexity and applications. This is a direct result of the continuously expanding success of these programs. Success can be me...
Most sub-bottom profilers of the 60s, 70s and 80s were only designed to generate cross-sectional images of seabed sediment layering and other sub-bottom features. The data were degraded by system limi...
Autonomous underwater vehicles (AUVs) are opening new dimensions to sea floor mapping, providing unprecedented accuracy in deep water as well as the potential to conduct engineering inspections and ma...
The Health, Safe and Environment (H, S & E) aspects of hydrographic surveys in the energy sector are a significant part of the planning and project management of any survey, which does not end with th...
An article from the June 2006 issue of Hydrointernationaldescribed our plans for utilising a hovercraft to deploy autonomous drifting echosounding Seafloor Sounding in Polar and Remote Regions (SSPARR...
Nautical charts are fundamental elements recognised by the United Nations Convention on the Law of the Sea (UNCLOS) for the accurate depiction of lines of delimitation drawn in accordance with the Con...
Researchers in this field are continually working to enhance the value, timeliness and ease-of-use of remotely sensed data products so that they can support an even broader range of information needs...
As the US Naval Observatory, which provides nearly half the global contribution to Coordinated Universal Time (UTC), shifts from a cesium to a rubidium standard atomic clock, we look to gain an order ...
As we seek solutions to the challenges posed by the world's coastal areas, it is important to take advantage of the expanding range of applications brought by new technologies to the venerable practis...
As the Gulf coast of the USA recovers, and preparation to rebuild progresses in the aftermath of Hurricane Katrina, the nexus between science and management will be crucial to informed coastal decisio...
The fast development of the aquaculture industry in Chile over the last decade has meant several undesirable effects on the environment and territorial organisation. This industry is producing revenue...
