Meet the Hydro International Team at Oceanology International (A-F)

In the third week of March, the entire marine world will be gathering in London, as this is where the biannual Oceanology International event is taking place. The exhibition and the conference bring together technological and scientific developments. With over 550 exhibitors and a state of the art conference programme OI12 is definitely the place to be. OI12 will be held from 13 to 15 March at the ExCel Exhibition and Conference Centre in London’s Docklands. The organisers are expecting at least 7,000 visitors to attend. Hydro international will of course be present. We not only have a stand (No.... (read more)

Ocean Business Ready for Business

Hands-on Update on Ocean Technology – Science and Business
The bi-annual event Ocean Business is coming to the NOC, Southampton from 4-6 April 2017. Three days of ocean technology engineering and science, knowledge sharing, hands-on training and demos as well as networking. The exhibition space is completely sold out, including more than 340 exhibitors. A selection of the businesses represented give a taster of their innovations in this preview. Better still, of course, is to come and see and experience for yourself! Ocean Business is more than just a trade show. There will also be seminars, workshops by suppliers, a general conference as well as a conference organised by... (read more)

Wideband Signals the Future for Acoustic Positioning

The high accuracy and availability of GPS has enabled the offshore survey community to deliver benefits to customers and fuelled demand for a corresponding improvement in subsea acoustic positioning systems. This paper describes the benefits of Sonardyne International’s implementation of the same Wideband signal processing techniques that are used in GPS and discusses the fundamental difference between GPS measurement processes and acoustic positioning systems. Narrowband Limitations Until recently the majority of acoustic positioning systems used narrowband toneburst signals and analogue signal processing methods which have suffered from weaknesses: a limited number of operating channels, susceptibility to noise and interference, and...

The Study of Mapping the Seafloor

What is the Difference Between a Bathymetry Chart and a Hydrographic Chart?
This article will immerse you into the deep water of Bathymetry. It explains in detail what a bathymetry map is, what it shows, what methods we use to collect the bathymetry data and last but not least, how to create a good quality bathymetry map. It will also cover the difference between a bathymetry chart and a hydrographic chart and the techniques our ancestors used in the past to collect and record depths. What is Bathymetry? Bathymetry is the study of mapping the seafloor. Bathymetric maps represent the ocean (sea) depth as a function of geographical coordinates, just as topographic maps... (read more)

Ocean Business 2013 Preview

More Variety at an Expanded Trade Show
Southampton, in the south of the UK’s Hampshire region, will be buzzing from 9 to 11 April 2013 as hydrographic, oceanographic and offshore professionals gather for an even bigger edition of Ocean Business. The organisers expect the 300 exhibitors to welcome 4,000 visitors and delegates to the National Oceanographic Centre grounds and inform them about the latest technologies. Hydro International invited exhibitors to give their preview, which we have published on these pages to give you a taste of what’s on offer during the event. 3D Laser Mapping 3D Laser Mapping is a ­world-leading provider of laser scanning technology. Established... (read more)

Capturing Convection: Glider Validated Modelling

Can Underwater Gliders Be Used to Check Ocean Forecast Accuracy?
Recently, three unmanned underwater vehicles (UUVs) were deployed in the northwest Mediterranean Sea to monitor open-ocean convection via changes in the local density structure. Mixed-layer depth and thermocline response to buoyancy flux were extrapolated from in-situ profiles and used to infer the occurrence of deepwater formation events. The high-resolution data set acquired has been used to assess ocean forecast model performance in this area. The advantages of employing glider data sets in further validation schemes are discussed here. Forecast models are employed by the oceanographic agencies for meteorological and commercial shipping applications, as well as in naval sonar propagation studies,... (read more)

Silt Density Measurements in IJmuiden

How a nautical depth chart is produced
IJmuiden (The Netherlands) is sometimes called "the gateway to Amsterdam". IJmuiden also accommodates a large fishing harbour and the Corus steel factory. Due to tidal currents and the shape of the breakwaters, continuous sedimentation of silt occurs in the waterway between breakwaters. The local waterway authority (the North Sea Canal Department, Dienstkring Noordzeekanaal) uses Nautical Depth Charts to supervise the contractor that carries out maintenance dredging. These charts are also sent to the pilot service to ensure the safe passage of deep draught vessels. To guarantee a detailed description of the most recent situation, every two weeks the Survey Department... (read more)

The Making of RV 'Kronprins Haakon'

New Norwegian Ice-breaking Research Vessel
Norway is a maritime country with a very long coastline, plus it is very much a polar nation with 80% of its sea territory and 45% of its land mass north of the Arctic circle. It is the only country with territorial claims both in the Arctic and the Antarctic. In spite of this, Norway has not had a purpose-built polar research vessel since Roald Amundsen’s 'Maud' (1917), having instead relied on converted commercial vessels for such purposes. That has all changed, however, now that 'Kronprins Haakon' has come into service. This article provides insight into the making of this new multi-purpose research vessel.... (read more)

Telepresence Technology

Running a Research Cruise from Shore
Telepresence, in this context, refers to the suite of technologies and operational methodologies required to allow key mission personnel to be located onshore while conducting ship-based oceanographic research and exploration. The technology required to support telepresence largely consists of a high-powered satellite-tracking antenna, advanced networking infrastructure, video/audio broadcast equipment and a suite of software tools for data sharing across the satellite network. This article attempts to explain the nuts and bolts of ship-to-shore telepresence systems. As a rule, exploring the unknown ocean cannot be accomplished effectively by a small group of scientists and engineers on board ships. They must rely... (read more)
