Following a Legacy

Hydro international Interviews Albert II, Prince of Monaco
At the invitation of Prince Albert I, the Principality of Monaco has been the headquarters of the International Hydrographic Organization since 1921. Looking at the annual reports of the International Hydrographic Bureau, the Government of the Principality has always been generous with the Organisation, providing it with beautiful premises and constant diplomatic support. Prince Albert II, Sovereign Prince of Monaco since April 2005, continues the tradition of his predecessors. Since 2001, Prince Albert is also president of the International Commission for the Scientific Exploration of the Mediterranean. He kindly accepted to be interviewed by Hydro international. You were named after... (read more)

International Geosurveying: the Perfect Job

Interview with George Darling, Gardline Group Chairman
The growing offshore exploration of the 1980s led to a booming need for survey-ships and many vessel-operating companies were founded, sometimes with only one old vessel. Saturation of the market resulted; many could no longer meet increased special and technical requirements for modern surveys and so disappeared, went bankrupt, were sold or merged with a bigger operator. Some, however, broadened their scope, modernised their fleet and sailed successfully into the international surveying business, offering not only hydrographic, geophysical, cable-route and EEZ-surveys but also oceanographic, environmental, geotechnical, data-processing and charter services. We interviewed the founder and present chairman of such a... (read more)

Snow Crab Tracking Using Wave Gliders

New Technology Bringing Science and Industry Together
Coastal communities around the globe are seeking better ways to understand and manage regional ecosystems. They depend on the ocean to sustain economic opportunities, ensure food security and safeguard fragile environments and species. For harvesters, scientists and government organisations in Nova Scotia, Canada, timely, accurate and comprehensive data on movements of valued species as crab is essential for designing effective fishery management regimes. Ocean Tracking Network (OTN), the Canadian government and local harvesters have been tagging and monitoring aquatic animals for years. But not all tracking methods are practical or cost-effective for highly mobile, yet slow moving animals like snow... (read more)

Crossing Thresholds in Seafloor Mapping

Hydro Int’l Interviews Capt. A. Armstrong, NOAA (retd)
US Hydro 2007 Conference takes place this month in Norfolk, Virginia, organised by the Hydrographic Society of America. It will be the eleventh event of its kind, celebrating the two hundredth anniversary of the founding of US Coast Survey. The conference will include technical sessions on the latest developments and applications in hydrographic surveying, multi-beam and side-scan sonar, data management, electronic charting, marine archaeology and related topics. Hydro International took this opportunity of interviewing president of the Hydrographic Society of America and regional correspondent for HI, Andy Armstrong. Can you give our readers a brief summary of your career in... (read more)

The MRU and SRF Aligned (I)

With increasing accuracies of positioning and multi-beam systems, alignment of the motion reference unit (MRU) is becoming increasingly important. Although most (if not all) multi-beam surveyors use the patch-test to resolve the angular offsets between the multi-beam head and the MRU, this test does not give us the angular offsets between the MRU and the ship’s reference frame (SRF). In addition to this, any misalignment between the vertical rotation axis of the MRU and the SRF (yaw-angle) will introduce cross-talk between pitch and roll.<P> The alignment of the threeaxes is also becoming increasingly important at shallower depths as we should...

Measuring the Uncertainty of a Swath Bathymetric Sonar

A Statistical Analysis for System Performance and IHO Compliance
In the last few decades, substantial efforts have been made to improve and facilitate the way hydrographic data is obtained. One technology is the EdgeTech 4600, an interferometric phase difference sonar. Unlike traditional interferometers, the EdgeTech 4600 is the first of its kind to offer complete swath coverage of the seafloor, even at nadir. Combining this kind of coverage with a vertical accuracy that exceeds IHO Special Order requirements in depths less than 30 metres, results in a sonar with superior area coverage rates, especially in shallow water. In the summer of 2012, bathymetric survey data was collected using an... (read more)

‘Hydrography is Both a Science and a Technique’

7 Questions to the New Director General of the French Hydrographic Office
Chief weapons engineer Laurent Kerléguer was appointed director general of Shom, the French hydrographic office, in July 2019. In this interview, Hydro International asks him about the latest developments regarding the world of hydrography, climate change and artificial intelligence. “It’s becoming more urgent than ever to measure the ocean.” In this interview, Laurent Kerléguer, director-general of the French hydrographic office Shom, discusses the latest developments regarding the world of hydrography, climate change and artificial intelligence.

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)

Ocean Business 2011 Preview

The third edition of Ocean Business will take place in Southampton, UK, from 5 – 7 April. The organisation anticipates more than 4000 visitors at the event, with 309 exhibitors from 19 countries. Ocean Business 2011 will be bigger than the previous editions, but will retain the cosy element, with exhibitors all taking relatively small stands. This time the organisation will have more vessels coming in, and there will be a full training and demonstration programme again. The organisation also found new locations for the offsite social events and the gala dinner venue is twice as big as last time.... (read more)

1997-2007: A Decade of Developments in Hydrography

We all know what is the oldest profession in the world. The second oldest is probably that of land surveyor: Adam undoubtedly wanted to stake out the boundaries of paradise in order to know what was and was not his. Paradise, or the Garden of Eden, was to be found in the land of the Euphrates and Tigris, where these two rivers converge at the town of Qurna in the present Shatt al Arab. And apart from his topographical activities Adam must also have made some hydrographic observations, probably just using a stick cut from a local fruit tree! After... (read more)
