Emerging Trends in Bathymetric Lidar Technology

What is on the Horizon for Airborne Lidar Bathymetry?
A surging interest in remote sensing and analytics has seen technology developments linked to these domains take off as we head into 2019. Airborne Lidar bathymetry (ALB) is no exception to recent innovations, especially with the growing recognition in the importance of high-resolution data to inform management of our oceans, seabed and coastal zones. In our recent discussions with ALB manufacturers and experienced operators, several significant new developments were revealed. The new developments include: Lightweight ALB sensor alternatives driven by the proliferation of Unpiloted Aerial Vehicles (UAVs) Increased point density for ALB across all feasible depths for improved detail and...

Hydrographic Surveying: Where Do We Stand

The Ever-increasing Accuracy of Mapping the Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those within the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared to... (read more)

The Advancing Technology of AUVs

A View of the Autonomous Underwater Vehicle Market
Since the last autonomous underwater vehicle (AUV) review in 2016, the market has continued to grow. The biggest market for AUV systems remains the military. The world’s most advanced Navies own and operate low-logistic AUV systems for mine countermeasures (MCM) in very shallow waters. These systems can operate in confined areas where MCM vessels cannot. The same systems can also be used in search and recovery operations, hydrography and salvage. This market used to be dominated by a handful of AUV providers. However, the number of manufacturers is increasing. Defence primes are also investing in these technologies through internal development... (read more)

Wärtsilä Unveils Targetless Laser Sensor for Offshore Wind Farms

Wärtsilä has launched SceneScan, a targetless laser sensor for offshore wind farms. SceneScan Monopole is among the first laser sensors developed for offshore wind farm applications where the need for installing fixed reflective targets is eliminated. This technology is designed to increase safety onboard service operation vessels (SOVs), since vessel positioning sensors that rely on targets fixed to the structure, are often unreliable because of poor placement, poor quality, and obscurement by workers on the platform. SceneScan has been designed and developed by Guidance Marine, which was acquired by Wärtsilä in 2017. SceneScan Monopole’s advanced software allows the measurement of... (read more)

Research Icebreaker Polarstern Begins Antarctic Survey Season

On 10 November 2018, the research icebreaker Polarstern left its homeport of Bremerhaven, bound for Cape Town, South Africa. This marks the beginning of her Antarctic season, in which oceanographic fieldwork in the Weddell Sea, a resupply mission to the Neumayer Station III, and explorations of the Larsen C ice shelf region and the South Shetland Islands are on the agenda. The ship is expected to return to Bremerhaven in June 2019. An expedition to the Larsen C ice shelf abutting the Antarctic Peninsula will be at the heart of the upcoming Antarctic season. The Peninsula is one of the fastest-warming... (read more)

MAP Team Discovers Oldest Intact Shipwreck in the Black Sea

The Maritime Archaeology Project (MAP) has discovered a Greek merchant vessel in the Black Sea (50 miles off the coast of Bulgaria) dating back to 400 BC - the oldest known intact shipwreck ever discovered. Because the water in the lower reaches is anoxic (lacks oxygen), the wooden cargo vessel has not deteriorated much since it sunk to the bottom all those centuries ago. Its mast, rudders, cargo, and even the benches where rowers sat are still well-preserved. Lidar and photogrammetry to create 3D images of the ships The ship was discovered during a three-year-long project. Over that time, the... (read more)

30th China Ocean Surveying and Mapping Academic Seminar

The 30th Ocean Surveying and Mapping Academic Seminar was held in Zhuhai on 29 August. The event was hosted by the Ocean Surveying and Mapping Committee of the China Society of Surveying and co-organised by Oceanalpha Intelligent Technology. The conference attracted nearly 200 delegates, including representatives from the Ministry of Natural Resources, the Ministry of Transport, the Ministry of Water Resources, the Chinese Academy of Sciences, the Navy and manufacturers of surveying and mapping instruments. Joint operation of USV, multibeam echosounder and 3D scanner On 31 August, the participants visited Oceanalpha’s unmanned vessel base and watched a demonstration of surveying... (read more)

USVs Conduct Underwater Topographic Survey in the Antarctic

In November 2017, China’s 34th Antarctic scientific expedition was officially launched. Two Oceanalpha M80 submarine exploration unmanned surface vehicles (USVs) and two SE40 hydrographic USVs accompanied the polar scientific research ship ‘Snow Dragon’ all the way south to Inexpressible Island on the west bank of the Ross Sea to assist in the construction of China's fifth Antarctic research station. Since the Ross Sea area had never been explored before, there was insufficient geographical data, making it difficult to find the ideal anchorage for the Snow Dragon. The USVs contributed to solving that problem by collecting bathymetric and topographic data. On 24... (read more)
