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 Bering Sea Survey

Adapted from Article by E. W. Eickelberg, Hydrographic and Geodetic Engineer, Commanding, US Coast and Geodetic Survey Ship Guide
1939 marked the beginning of a concerted programme to chart the Bering Sea area. The surveys in this area that were conducted prior to United States entry into the Second World War marked some of the last that were done in frontier areas prior to the advent of the era before electronic navigation systems, shallow-water fathometers, and widespread  use of gyrocompasses, outboard motors, helicopters and other tools that eased the work of mid-to-late-twentieth century hydrographers. The Coast and Geodetic Survey Ship Guide, under the command of Commander Ernest Eickelberg,  was assigned the initial work associated with this endeavour and commenced... (read more)

A New Beginning

ISO 9001-2000 for French Hydrographic Office
As pointed out by many preceding the French Hydrographic Office, SHOM, on the path of certification, the rapid growth of information systems and automation has often outpaced updating of procedures. This has resulted in a growing gap between what was being actually done and what was written on what was to be done. For organisations like SHOM, where safety and traceability are nearly sacred, this gap had to be filled. In addition, the systems used for surveys and for production ashore are growing in complexity and their quality has a direct impact on the quality of products, including integrity of... (read more)

Rheology as a Survey Tool

“We Are Not There Yet”
To reduce the dredging cost many harbour authorities and governmental bodies are seeking for a more suitable and a rheology-related survey tool. The in situ instruments available on the market are based on mechanical, acoustical, optical or radioactive measuring principles. But before one will be able to map the real nautical bottom, we need to understand the influence of the mud properties (micro scale) on a vessel (macro scale). This article gives an overview of the general reaction forces of the mud which definitely play an important role in the vessel behaviour when sailing into it. Without naming any commercial...

Lessons Learned From the AF447 Search

Hydro International Interviews Mike Purcell
It was a rainy day at Woods Hole, Massachusetts, USA. The scenery reminds me of the Twin Peaks atmosphere. I am about to interview Mike Purcell, the man whose search team finally found the wreckage of flight AF447 in the deep ocean in 2011. Only five years after this tragedy a second airliner, the MH370, vanished into the deep ocean. Major search operations have been going on since then. Hydro International found this to be a good reason to look back with Mike and see what lessons have been learned in this deep ocean search operation. When did WHOI get... (read more)
