Oceanology International to have Three Points of Focus

When Oi08 opens at the ExCeL centre in London’s Docklands on 11 March, the exhibition and its accompanying conference will focus on the three important issues that have begun to dominate thinking in ocean science and technology: climate change, meeting future energy demands, and ensuring environmental and civil security. These have become interconnected issues, with expertise now moving freely between each of these apparently specialised sectors.<P> With a 3-day conference accompan­ying this major exhibition, it is almost inevitable that public concerns about climate change will attract considerable interest. The role of the oceans in global warming is likely to take... (read more)

Excited by Automation Driven by Autonomous Vehicles

Hydro International Interviews Capt. Shep Smith
NOAA is one of the bigger organisations in the world that has surveying and charting in its portfolio. It’s an immense task as the USA has about 95,000 miles of coastline, important ports and a wide range of users – from recreational boaters to the biggest container vessels and tankers. The country also has to deal with environmental disasters like hurricanes and oil spills. NOAA is undergoing changes as the chart portfolio is ‘going digital’ and new initiatives such as using Maritime Autonomous Systems (MAS) for surveys. Hydro International interviews Capt Shep Smith, who generously gave an insight behind the scenes.

Danish Hydrographic Office Turns to GIS For Automated Maritime Charting

A Radical Update Was Needed
Denmark has challenging seascapes to map and chart. It has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for Greenland were created in the 1960s. When GPS started to gain prominence, a radical update was needed. Apart from its 42-mile land border with Germany, the peninsular country of Denmark, with its scores of bays, straits, and fjords,  is surrounded almost entirely by the North and Baltic Seas. Denmark is also composed of more than 400 islands, including the Faroe Islands, located in the Atlantic Ocean between the United Kingdom... (read more)

Starters in Hydrography

Hydro International interviews Lieutenant Matt Templeton, Elise Bergsma, Michelle Weirathmueller and Mohd Zukhairi Abd Latef
There is a global shortage of hydrographic surveyors. Vacancies and demands for personnel at sea mean surveyors are becoming the most wanted specialists in the offshore world. Institutes of hydrographic education around the world are struggling to attract enough students and companies are taking on students before even they have graduated. We found some students at the start of their careers and asked them what they expected from their life in hydrography. HI : Why have you decided to become a hydrographer?Templeton: I like the balance between the hard days in the field and the challenging evenings working through the... (read more)

The Dawn of the Digital Age

How digital visual systems lower costs and improve efficiency
Traditionally, Video Inspection surveys have been performed by ROV using analogue CCD colour cameras, with the video pictures recorded to S-VHS videotapes. This technology has served the industry well for more than twenty years but technology moves on: the world watches films on DVD, digital video movie trailers can be viewed over the internet and 3G mobile phones allow digital video clips to be viewed on the move. We are about to witness the same paradigm shift in the way we handle video information as occurred twelve years ago when CD audio replaced analogue vinyl recordings. Digital video systems offer...

US Navy Hydrography Is Back!

The US Navy has a strong tradition in hydrography and has restated its commitment to this field by naming the Commander of the Naval Meteorology and Oceanography Command as the ‘Hydrographer of the Navy’. This was the culmination of significant focus and effort during the past decade by the US Navy’s meteorology and oceanography (METOC) community to improve not just hydrography, but all forms of environmental data collection. During the Cold War, METOC resources were concentrated on deep-water operations; hydrographic expertise, especially among Naval officers, was not maintained at a sufficient level to support the current naval doctrine of littoral...

The Impact of the Physical Properties of Water in Dam Lakes

In Accordance with the Results of the Echo Sounding and Reservoir Capacities
Technical managers and users of hydrographic surveying results of reservoir dams mainly pursue the amount of sedimentation and the authentic volume of the reservoir under their management. But to what extent is the data obtained reliable? It would appear that the following factors could be effective in gaining this objective: Technical, modern and updated hydrographic guidelines, Advanced equipment and their appropriate application,Timely calibration during equipping and the elimination of systematic errors,Qualified, experienced, trained and specialised manpower, The application of methodology, according to the hydrographic guidelines of the reservoir,Correct data processing, including the enforcement of the essential amendments and the rendering of the...

The Importance of Continuous Education

How Fugro Academy Advances the Company’s Business
It is now well over ten years since Fugro Academy opened its doors within Fugro as a focal point for learning and development for the company’s 10,000-plus employees, who specialise in providing geoinformation and asset integrity services to a global client base. So, what is Fugro Academy and how does it contribute to the ongoing education and professional development of the largely technical workforce? Andrew McNeill, global talent development manager at Fugro, explains more. Fugro Academy was established in late 2006. Around that time, Fugro was working in a very buoyant market, particularly for services related to oil and gas,... (read more)

A Farewell to Times Past

HI Interviews Admiral Steve Ritchie, Columnist ‘As it Was’
We have all enjoyed the column entitled ‘As it Was’, contributed since the very first issue of Hydro international by Admiral Steve Ritchie. The piece has always been very much appreciated and we have received many positive reactions to it. Steve’s lifetime has encompassed the technical revolution in hydrography; it is seventy years since he entered the surveying service and forty since he became UK Hydrographer. So that in terms of memory alone he was the perfect man to carry the ‘As it Was’ column. But he also had a reputation as author of some interesting publications, including his books... (read more)

3D Sonar in Object Detection

Intuitive real-time imaging for sub-sea visualisation and classification
Sonar is well accepted as an option for detection and visualisation of underwater objects. Side-scan and sector-scanning sonar have traditionally been used by surveyors but whilst they produce excellent images, these are often difficult to interpret accurately. This article describes new developments in 3D-sonar and their advantages and use in emerging underwater disciplines. Classic applications for object-detection are many and varied, ranging from looking for items such as wreckage, debris, lost items and so forth to defence applications, seeking out threats such as mines. Increasingly, though, object detection has been expanded to include obstacle avoidance for both surface and submersible... (read more)
