USVs Developing into Versatile Tools

Extending the Boundaries of Hydrographic Surveying
Unmanned surface vehicles (USVs) are gaining terrain in hydrographic surveying. They combine the advantages of small survey vessels with those of unmanned survey platforms, giving them a range of applications that is likely to expand even more. They enable hydrographic surveys in a greater number of areas, both inland and offshore. Due to the size of some USVs, they can access waters that are either too shallow for a regular survey vessel or difficult – even dangerous – to access to allow mobilisation of a manned survey vessel. This makes them the survey platform of choice for inshore and coastal areas like... (read more)

Shallow Survey 2005
The 4th international conference on high-resolution surveys in shallow waters took place in Plymouth (UK) from 12 to 15 September. The conference focused on the ‘Common Data Set’ (comparison data obtained by different survey systems over an area of seabed close to the conference venue). The conference included 40 high-quality presentations. Twenty-three exhibitors also took the opportunity to display their products to the 250 international delegates. The Shallow Survey Conference (SSC), a bi-annual conference focusing on the latest developments and research in shallow water surveying, was held in Europe for the first time. Previous conferences have been based in Sydney,... (read more)

Multibeam Data Processing

Using CUBE Surfaces for Nautical Cartography and Dredged Measurements
This article is about the evolution of acoustic sounders imposed on Hydrographic Service’s new methodologies for the interpretation, handling and application of hydrographic information. Considering spatial resolution and high-density data acquired by multibeam echosounders (MBES), algorithms such as Combined Uncertainty Bathymetry Estimator (CUBE) are used in the processing workflow to generate depths and uncertainty estimates. Can bathymetric surfaces be considered the final survey product in exchange of the traditional shoals selection? IHPT conducted hydrographic surveys in order to evaluate CUBE processing for nautical cartography and for dredged volume calculation. Shoals validated by hydrographers were compared with CUBE estimated depths and... (read more)

Hydrographic Society Benelux

News On Wednesday 22nd October 2003 the Hydrographic Society held a workshop sponsored by MacArtney Benelux. The theme of the afternoon meeting was Ocean Profiling Systems and the programme consisted of three lectures that gave attendees the opportunity to learn more about the subject systems and MacArtney in general. The first lecture was by Ron Voerman, General Manager of MacArtney Benelux. He gave the attendees an introduction to and overview of the MacArtney group and their activities world-wide. Mr Arnold Furlong of Brook Ocean Technology (BOT) Canada, followed on with a detailed description of their Moving Vessel Profiler (MVP). For... (read more)

‘I want to help the guys in the field'

Hypack founder Pat Sanders visited The Netherlands, presenting during the Holland Hypack Show which was organised by Nautikaris. Hydro International took the opportunity to interview him on various aspects of the business. Does Hypack have a rough ride? Is it difficult to expand and maintain the ‘close to the user' approach?   By Joost Boers, content manager, Hydro International    Hypack exist for more than 20 years, how did the company start? Sanders: ‘After serving as a hydrographer with the Naval Oceanographic Office, I left for business school to become a Captain of Industry.  It turns out that I was only... (read more)

Morphology, hydrography and sediment dynamics in a mangrove estuary: The Konkoure Estuary, Guinea. Capo, S., Sottolichio, A., Brenon, I., Castaing, P. and Ferry, L. 2006. Marine Geology, 230: 199-215. The Konkoure Estuary in the Republic of Guinea is a poorly understood atypical mangrove system. Sediment dynamics in tropical estuaries are controlled by a combination of processes including river discharge, morphology, salinity, erosion and deposition processes, the settling of mud, physico-chemical processes and mangrove swamps.The paper presents a consistent set of data aimed at characterising the estuary and thus, increasing our understanding of tropical systems, as well as studying the impact...

Technical Awareness Seminar 2003, South Africa
In early December 2003 the Hydrographic Society of South Africa held a four-day Technical Awareness Seminar (TAS) hosted by the Institute for Maritime Technology (IMT) in Simon’s Town, South Africa. The theme for the Seminar was ‘New Technologies for a New Century’. Over one hundred delegates from the Southern Africa region attended the TAS, providing a good representation of the regions Offshore Mining Companies, Oil & Gas Industry, South African Navy, Research Institutions, Educational Institutions and Local Marine Suppliers. Delegates generally registered for just one of the four days, as presentations and demonstrations were repeated every day. However, due to... (read more)
