Exploring Coral Reef Sustainability

The Island of Bonaire in the Southwest Caribbean, a Marine Protected Area since 1979, has one of the most pristine coral reefs in the region. The last synoptic survey of the leeward coast was by the Dutch scientist Dr Fleur van Duyl in the 1980s and parts of the deeper reef have never been mapped. In January 2008, the US National Oceanic and Atmospheric Administration (NOAA) funded a unique expedition to Bonaire, deploying three compact Autonomous Underwater Vehicles (AUVs) carrying various oceanographic instrumentation packages and a swath bathymetry sonar.<p> The crystal-clear watersand schools of reef fish made an enchanting setting...

“How to Sustainably Use and Protect Oceans and Coasts”

Hydro International Interviews Dr Walter Cruickshank, Acting Director, BOEM
During the recent Offshore Technology Conference in Houston, Texas, USA, the Executive Order on Implementing an America-First Offshore Energy Strategy was signed to support offshore science development. In the context of the highly dynamic offshore energy sector, 'Hydro International' interviewed Dr Walter Cruickshank, acting director of the Bureau of Ocean Energy Management (BOEM), about accelerating authorisations for seismic surveying, marine geospatial data, environmental monitoring and the potential of marine renewable energy. What is the role of maritime geospatial data for BOEM? BOEM uses maritime geospatial data for a variety of needs. For example, by identifying ocean areas used for various... (read more)

Looking Far beyond the Horizon

Hydro International Interviews Steven Xu, CEO, Hi-Target
These are exciting times in the geomatics and hydrographic industry. Innovative solutions are being developed, integration is the main keyword and the big players are acquiring smaller companies that add a new dimension to their portfolio. Europe, Japan and North America are traditional strongholds of geomatics, but several very ambitious companies from China are doing their utmost to catch up with the frontrunners. Steven Xu, CEO of Hi-Target, was more than happy to share his thoughts and expectations with Hydro International. Read the interview here. Wim van Wegen and Joost Boers, Geomares Publishing, The Netherlands Hi-Target was established in Guangzhou,... (read more)

Shallow Survey 2003

Interview with Dr Phil Chapple, Scientist, Conference Convenor, Australia
After completing a Bachelor of Science with Honours in Physics in 1983, Dr Phil Chapple worked in a laboratory of the Australian Defence Science & Technology Organisation (DSTO) where lasers were being developed for Australia’s Laser Airborne Depth Sounder (LADS). He returned to university to study for a PhD in Physics (laser spectroscopy), returned again to DSTO to investigate laser-material interactions and later worked some years on statistical image processing techniques. He completed the degree of Master of Mathematical Sciences (Signal & Information Processing), meanwhile learning details of sonar signal processing. In 1999 he moved to the DSTO Maritime Operations... (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)

Innovator Measuring ‘Salt Fingers’

Interview with Albert J. Williams III, Woods Hole Oceanographic Institution, USA
Mr Albert J. Williams III was given the IEEE OES Distinguished Technical Achievement Award in 2000; a prestigious prize, as one of the earlier winners was Robert J. Urick. Mr Williams has spent many years at Woods Hole Oceanographic Institution doing research in oceanography and developing instruments for current and for shear measurements. He chairs the IEEE Current Measurement Technology Conference in March 2003 in San Diego. It thus seemed a good moment to ask Mr Williams about his career, developments of today and tomorrow in current measurement equipment, and the Current Measurement Technology Conference. Please give our readers a... (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)

Slocum Gliders Make Historic Voyages

Autonomous vehicles from the company founded by AUV pioneer Doug Webb have recently made a historic 2600km voyage from New Jersey to Halifax and successfully drawn power from ocean thermal gradients for 3000km worth of data collection between St Thomas and St Croix.<P> Ocean engineers’ dreams docome true, as demonstrated by Doug Webb of Teledyne Webb Research, Falmouth, Massachusetts, USA. When he left the Woods Hole Oceanographic Institution in 1982 after 20 years there, it was to form his own company Webb Research Corporation, recently acquired by Teledyne, to develop and manufacture floats and sound sources. However, he was dreaming... (read more)

First Command

Ensign Niblack Showed Himself to be a Decisive and Courageous Captain
Albert Parker Niblack, third director of the International Hydrographic Bureau from 1921 and second President from 1927, had been an officer in the United States Navy for eleven years when he earned his first command. In 1887, he was thirty years old and had been attached to the Coast and Geodetic Survey Steamer Patterson for the past three years. He was apparently a plank owner on the Patterson as he was assigned to the vessel on 2 July 1884, in New York City. The ship began its voyage to the Pacific Ocean on 30 July 1884, and arrived in San... (read more)

GIB Portable Tracking Systems

The underwater use of GPS
Why has a new positioning system been designed? What are the requirements? What are the drawbacks of traditional solutions? Why are a new concept and system architecture necessary? What applications are addressed? What performances can be achieved? In the field of underwater positioning, many solutions exist and people are often satisfied with the traditional solutions they are used to. LBL and USBL are widely used for underwater positioning in various applications, though they present some installation and calibration constraints and operational limitations. Their performance can be over estimated and in some cases are not justified. If you push surveyors towards... (read more)
