Remote Hydrography Conference Rescheduled for May 2020

The Hydrographic Society UK has recently decided to reschedule its two-day Remote Hydrography conference (originally due to take place in late October 2019) for 6-7 May 2020. The venue remains the National Oceanography Centre, Southampton. A revised Call for Abstracts for the new dates will be issued very shortly, with a deadline of 31 December 2019, and the programme to be confirmed in February. Potential speakers who have already submitted an abstract do not need to do so again unless they wish to take the opportunity to update it. Opportunities for Demonstrations With the obvious exception of the dates, all arrangements... (read more)

Taiwan Boosts its Current Ocean Research With New Fleet

A new fleet of oceanographic research vessels is expected to be launched in the first half of 2020. This means a boost to Taiwan’s ocean current research and homeland security protection. The fleet will comprise four ships, three of which are to be delivered by early next year, including two 500-ton vessels and one 1,000-ton vessel. The new ships are domestically developed and manufactured through a collaboration between academia and industry, sponsored by the Ministry of Science and Technology, reports CNA, the Central News Agency of Taiwan. Legend is Taiwan’s fifth-largest research vessel and was built by Triyards Marine Service, a Singaporean... (read more)

Russian Floating Nuclear Power Unit Sets Sail to the Arctic

Last Friday, Russia's first floating power unit (FPU) Akademik Lomonosov set sail from the Arctic port of Murmansk for Pevek, Chukotka, in Russia's Far East, where it will provide power to one of the country’s most remote regions. This is sparking environmental concerns. Developed by the Russian state nuclear company Rosatom, the plant set off on a 5,000km (2700nm) journey through Arctic waters to reach the Chukotka region, which lies across the Bering Strait from Alaska. The plant, loaded with nuclear fuel, will replace a coal-fired power plant and an ageing nuclear power plant supplying more than 50,000 people with electricity in... (read more)

Compact ARCboat Lite Enables Safer and More Efficient Surveys

The ARCboat Lite is a portable and compact version of HR Wallingford’s award-winning remote-controlled survey vessel, the ARCboat. Weighing only 15kg and just 1.3m long, the ARCboat Lite can be carried and deployed by a single person and easily fits inside the boot of a typical family hatchback. It can operate in flows of up to 2.5m/s, in water as shallow as 22cm, and it costs less than the larger ARCboat. According to the manufacturer, both ARCboats are safer than manned vessels as operators can survey from the bank rather than venturing out on to the water. They also minimise... (read more)

Autonomous Sailing Platform to Gather Data for Offshore Wind Projects

Norwegian offshore wind developer Equinor and US-based start-up Autonomous Marine Systems (AMS) have launched a 16 ft autonomous sailing platform to cut the cost of gathering data needed for developing offshore wind projects. The wind and solar-powered Datamaran vessel, developed by AMS, carries a LiDAR device to collect data on wind and weather conditions at remote offshore wind lease areas. Over the last 18 months, Equinor and AMS have conducted studies and built prototypes to test the system. These studies have shown dramatic improvements in lead time, cost and areal coverage versus today’s options, according to the partners. The maiden Datamaran... (read more)

Preparing for Hydrographic Artificial Intelligence Network and Systems

Success Depends on the Quantity and Quality of All Available Data
With the ever-increasing and affordable availability of capacity and computing power to process and store data, the emergence of artificial intelligence (AI) in marine geomatics, ocean sciences and hydrography is palpable. Mathematical models are very powerful, but their reliability must be validated and demonstrated using calibration points. It's the same thing for AI. It cannot emulate and learn properly if it cannot rely on observations that represent reality. In the commercial shipping world, AI-based technologies are about to be tested, resulting in additional bathymetry and hydrography needs that will quickly become necessary and critical. Commercial Marine Autonomous Surface Ships (MASS)... (read more)

Seismic Activity Data Collection on the Ocean Floor

Sponsored Article
Unlike neighbouring Japan, earthquake activity is infrequent in the peninsula area of South Korea, and those that do occur tend to be low in intensity. Typically, earthquakes in this region measure between 2.0 and 5.0 on the Richter scale[1]. The record for the quake with the highest magnitude on the Korean Peninsula stood for some time, recorded at 5.3 in 1980. This was recently overtaken by a 5.8 magnitude tremor in Gyeongju in 2016 and a 5.4 magnitude tremor in Pohang, followed soon after by a 4.8 magnitude aftershock tremor. Data on these events is collected using the existing seismological... (read more)

Satellite Trackers to Mark Ghost Nets

Ocean Voyages Institute, a non-profit organization, has successfully removed more than 40 tons of fishing nets and consumer plastics from the area known as the North Pacific Subtropical Convergence Zone, or more commonly known as the Pacific Gyre. The sailing cargo ship Kwai, arrived in Honolulu, Hawaii, after a 25-day clean-up mission. In the Pacific, between California and Hawaii, four ocean currents converge to create a vortex that collects huge amounts of plastics. This debris field covers vast expanses of ocean, the organization says. Fishing Ghost Nets A prime target for Ocean Voyages Institute’s 2019 voyage was the fishing gear called... (read more)

Expanding the Knowledge of Arctic Ocean Bathymetry

Scientists from DTU Space, Denmark’s national space research institute, have published a paper that reveals the first Arctic bathymetry map using marine gravity. Previously, the knowledge of the depth and shape of the Arctic Ocean floor (its bathymetry) has been insufficient. Owing to year-round sea-ice coverage and the cost of research in this remote region, much of the Arctic Ocean’s bathymetry has remained a mystery, until now, according to a recent publication by the European Space Agency, which can be found at www.easy.int. Bathymetry maps are crucial for studying ocean dynamics, currents and tides, as well as for ship safety. Several... (read more)
