Providing Security and Military ROV Solutions

Deep Ocean Engineering (DOE, USA) delivered a Phantom HD2+2 to the Federal Bureau of Investigation (FBI), New York Underwater Evidence Search Team. This vehicle’s maiden launch was as a search vehicle to the Cayuga Lake Search Project. The vehicle was also used to recover bodies from the New Melones Lake, evidence in a California crime case. The FBI project tasks included survey, monitoring and other initiatives associated with evidence gathering and research. With current events as they are, the military market has challenging new requirements that exceed the capabilities of off-the-shelf technology. For those especially challenging military applications, Deep Ocean... (read more)

Mapping the Seafloor with Remote Sensing and Satellite Imagery

An Analysis of the Techniques and Benefits of These Methods
70% of the Earth is covered by water, but so far just 7% of it has been surveyed (Mars, Venus and the Moon are better surveyed). Hydrography as a science has changed dramatically since the first measurements were made by Alexander Dalrymple and James Cook with lead lines and sextants. Singlebeam echosounders were invented in the 1920s – a technology still used today for mapping the seafloor. This method of using echosounders can produce very high-resolution bathymetric data but the high operational costs and the slow working process make it economically unsuitable for covering large areas. However, with the ongoing expenses of... (read more)

GRACE Follow-up Mission to Keep Close Eye on Ice Loss

A few months ago, the GRACE mission’s two Earth observation satellites burnt up in the atmosphere. Although this loss was planned, for the experts at the Alfred Wegener Institute it left a considerable gap in monitoring ice loss in the Antarctic and Greenland. Now the follow-up mission will finally be launched, and will play a vital role in predicting future sea level rise. One of the greatest threats in connection with climate change is the continuing rise in sea level – and the more intensively the enormous ice sheets in Greenland and the Antarctic melt, the worse it will become....

Hydrographic Surveying in the Port of London

Charting for the 21st Century
By the end of this year, the gap will have finally closed on the mandatory requirements for ships to carry an Electronic Chart Display and Information System (ECDIS), with all existing vessels of over 10,000GT being required to be so equipped (all new vessels greater than 3,000GT already have to comply). This article explores the provision of the chart data for the Electronic Navigation Charts (ENC) available to such systems and how the UK's Port of London Authority (PLA), as a major port, is providing such data. This article has been brought to you by Teledyne CARIS To survey the... (read more)

iXblue Equips Manned Submersible for New 'Titanic' Survey Expedition

OceanGate, a provider of manned submersible services, and iXblue, a global company that provides innovative solutions for navigation, positioning and underwater imaging, are combining forces to conduct the first manned submersible expedition to the wreck of the RMS 'Titanic' since 2005. iXblue’s Phins 6000 inertial navigation system and Posidonia USBL positioning system will both be used for the accurate and reliable navigation and positioning of OceanGate’s 'Titan', the newest addition to the company’s fleet of deep -sea manned submersibles and the first privately owned manned submersible capable of reaching 'Titanic' depths. “Our submersible pilots have relied on Phins from iXblue...

Mapping the Deep Ocean with Multiple AUVs

Ocean Infinity’s Seabed Exploration Project
Ocean Infinity’s seabed mapping campaign commenced in the summer of 2017. The Ocean Infinity team is made up of individuals from multiple disciplines, who have gained vast experience with deep-sea exploration operations in the past. Their combined knowledge and insight led to the idea to undertake deep-sea mapping operations using up to eight autonomous underwater vehicles (AUVs), paired with eight unmanned surface vessels (USVs). This novel concept is explained in more detail in this article. Human inquisition drives us to explore. This has led man to delve below the surface of the oceans. Our ability to understand the undersea world... (read more)

Bibby HydroMap Strengthens Asset Inspection Service Offering

Bibby HydroMap has announced the expansion of its specialised asset inspection survey technology with the purchase of the Carlson Software Merlin Lidar mapping system. The Merlin Lidar system will complement Bibby HydroMap’s existing marine and terrestrial survey equipment to deliver improved high-resolution datasets of objects of interest, with the aim of enhancing the validity of asset inspection services. The new system is a vessel-based 3D mobile marine laser scanner system, designed to seamlessly integrate with existing hydrographic equipment, therefore allowing simultaneous data acquisition above and below the waterline. Producing an accurate 360° dataset in a single pass, both acquisition and data... (read more)

30+ Years of Hydrographic Education

Category A Programme of Hamburg’s HafenCity Universities
A hydrographic education programme has been offered in Hamburg for more than 30 years. The programme was first offered in 1985 as an addition to an existing programme in general surveying, and the course became fully recognised as a Category A programme by the IHO in 1990. The Hydrography programme has been integrated as a specialisation in the two-year MSc in Geodesy and Geoinformatics at HafenCity University since 2009. In March 2017, the current programme was re-recognised as one of the first against the new standard S-5A. With the new recognition in place, the programme has shown that it is... (read more)
