Oceanology International 2010 Preview (2)

This is the continuation of the Oceanology International Preview. For companies A - L, see part 1  MacArtney Underwater Technology Group MacArtney will be introducing their newest innovation in multiplexers - the NEXUS MK E electrical multiplexer, which is designed to the same high standards as the fibre optic multiplexer range with the telemetry part of the multiplexer adapted to non-fibre optic cables. Another highlight will be the demonstration of a working active heave compensation winch, the Cormac 3 Stainless Steel winch. It will demonstrate load stability during vessel movement on the sea. MacArtney will show their Focus ROTV, camera... (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.” 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.” Laurent Kerléguer was born in Brest, France, and has always lived by – or close to – the sea. Although he never had a ‘dream job’ as a child, he always had the feeling that his career would be linked to the sea. “For me as an engineer, hydrography is the perfect... (read more)

Much More Than a Typical Hydrographic Office

Hydro International Interviews Capt Brian Connon, Director NGA Marine Safety Office
In October 2015, Capt Brian D. Connon assumed the role of director of the National Geospatial-Intelligence Agency’s Maritime Safety Office. The organisation is an important, although not always visible, link in the global maritime safety chain. Its work contributes to generic marine safety and, due to the nature of the data collected and analysed, its role is especially relevant for security, humanitarian assistance and disaster relief. In this interview with Hydro International, Capt Brian Connon lays out the role of hydrographic data and technologies in the NGA. Can you briefly outline the work of the NGA? The National Geospatial-Intelligence Agency (NGA) is the United States’ primary... (read more)

Shallow Survey 2005 Common Dataset Comparisons

Shallow Survey 2005 Common Dataset Comparisons As part of the Shallow Survey Conference 2005 held in Plymouth, swath sonar manufacturers were invited to survey a common dataset. Two regions were chosen: an offshore area south of Plymouth breakwater suited to larger vessels and Lidar operations, and an inshore area around Plymouth Hoe. The data collected for the inshore area serves as the basis for this study. The manufacturers and systems that provided data for the inshore area are listed in Table 1. Each of the surveys was undertaken with the same supporting equipment, and mostly using the same vessel. RTK... (read more)

2D/3D Web-mapping

Web Visualisation Coastal Orthophotos
This paper describes the development of a web spatial image server used for sharing huge sets of georeferenced coastal orthophotos on the web via an easy visualisation interface. Traditional cartography was considered a highly sophisticated methodology for the production of high-quality maps, using the sales-business model of the non-internet economy and dedicated to specialists. The recent arrival on the scene of three internet leaders whose general mission is to map everything, and the release of their popular online earth browsers has had a huge impact in the geomatics arena. All are by now familiar with the success enjoyed by Google... (read more)

Hydrography for Exploration

Interview with Roger Lott, Head of Survey for BP Exploration, London, UK
In the last half century Hydrography has grown from a Government commitment, solely for the purpose of producing nautical charts and information for safe navigation, into a science indispensable to all sorts of offshore industrial activities. One such activity is offshore Oil and Gas exploration and exploitation. It is well known that this offshore industry has given birth to many fascinating technical developments in hydrography. Roger Lott, Head of Survey for BP Exploration based in London, agreed to be interviewed by Hydro international to inform the readers concerning specific items in offshore surveying for this industry. Can you give the... (read more)

Increased-resolution Bathymetry in the Southeast Indian Ocean

MH370 Search Data
The disappearance of Malaysian Airlines flight MH370 on 8 March 2014 led to a deep ocean search effort of unprecedented scale and detail in the remote southeastern Indian Ocean. Between June 2014 and January 2017, two mapping phases took place: (1) a shipborne bathymetric survey, and (2) a higher-resolution search in areas where accurate mapping of the seafloor was required to guide the detailed underwater search aimed at locating the aircraft wreckage. The latter phase used sidescan, multibeam and synthetic aperture sonar mounted on towed or autonomous underwater vehicles (AUVs). This article describes the mapping of the area where the...

Hydrographic Research and Education in the USA

Interview with Captain Andy Armstrong
In her July/August 1999 issue Hydro international (HI) interviewed Captain Andy Armstrong. The interview was focused on New Approaches, Products and Technology in NOAA. Captain Armstrong announced his move to New Hampshire to start working as Co-Director on the Joint Hydrographic Centre (JHC) and the Centre for Coastal and Ocean Mapping (CCOM) to be established. What happened to the ambitious plans? HI interviewed him once more on progress and realisation of the original plans and his views on the hydrographic future in general. Please give our readers a summary of the development of CCOM/JHC since the previous interview in July/August... (read more)
