We Visited for You

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)

Zooming in on Bathymetric Techniques

The study of the underwater depth of ocean floors is called ‘bathymetry’. The term originally refers to the ocean’s depth relative to sea level. Bathymetry is the underwater equivalent to topography, which actually makes it the cornerstone of hydrographic science. There are multiple ways to derive bathymetric information. Below are a selection of articles that zoom in on various bathymetric techniques, ranging from satellite-derived bathymetry – using multispectral satellite imagery – to airborne Lidar mapping. Improving Satellite-derived Bathymetry Using Spatial Regression Algorithms Bathymetry is traditionally acquired using singlebeam or multibeam echosounders. This method produces accurate depth measurements along transects but... (read more)

Hydrographic Society, Denmark

Re-surveying Making a new chart of the western Baltic Since the beginning of April two Royal Danish Administration of Navigation and Hydrography (RDANH) smaller survey boats, SKA 15 and SKA 16, have been conducting a hydrographic survey in the western part of the Baltic, SW of Gedser, in an area near the Danish-German exclusive economic zone. Up until this year Denmark has not conducted hydrographic surveying in the above mentioned area and therefore no soundings existed for this area. The soundings represented in the charts originated from older German surveys. These old soundings did not meet the present standards for... (read more)

Taking a Risk

For the better part of 1999 I found myself posted to HMNZS RESOLUTION as a newly promoted Petty Officer. During this period, RESOLUTION was conducting her first survey as the Royal New Zealand Navy’s primary hydrographic vessel. She was continuing on from survey work carried out by her decommissioned predecessor, HMNZS MONOWAI, in New Zealand’s southern most areas of Stewart Island and the western end of Foveaux Strait. This was not only RESOLUTION’s first survey but her first with the MultiBeam EchoSounder (MBES). Tidal sites were established at various locations, Port Adventure, Yankee River, Small Craft Retreat and of course... (read more)

Monitoring Sludge Disposal

Dredging is essential to maintain navigation in ports and harbours. Much of the material that is removed during dredging is clean enough to be disposed of in open water depots at sea. According to the protocol defined in the London Convention (1972 and 1996), the impacts of these open water depots on the surrounding environment have to be monitored. Thus far, monitoring of sediment mobility and sediment transport has mainly been carried out by point measurements. These measurements provide only limited information and sometimes require ambiguous extrapolations. With the development of systems that provide high-resolution, quantitative information of morphology and... (read more)

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)

Developing New Skills

Marin Mätteknik AB
Marin Mätteknik AB (MMT AB) is a survey company based in Gothenburg (Sweden), offering turnkey solutions to customers requiring high-resolution sea-floor mapping, geology or remotely operated vehicle (ROV) services. The company has expanded significantly in recent years and is expanding into new market segments, with a significant increase in ROV, environmental and geotechnical capacities.<P> MMT AB was founded in 1976 bymarine biologist Ola Oskarsson, using a small skiff, pursuing his dream to investigate the sea (Figures 1 and 2). The focus soon turned to bathymetry, geophysics and survey software integration. The first multi-beam echosounder was purchased in 1994. The breakthrough... (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)
