UKHO's Phil Payne Talks About Overseas Territories Seabed Mapping Programme

"Check and double-check your data before getting somebody else to check it for you", says Phil Payne, survey delivery manager of the UK Hydrographic Office when he talks about hydrographic programmes to support the blue economic growth, intentional projects and the use of lidar for charting purposes. "There will be a continued drive towards autonomy and automated processing.” Prior to his work with the UK Hydrographic Office (UKHO), Phil Payne spent 25 years in the Royal Navy as a hydrographic and meteorology specialist. Since joining the UKHO in 2016, he has worked in a number of different roles, most recently as its Survey... (read more)

Sea-level Rise Could Affect Hundreds of Millions of People

Global vulnerability to sea-level rise is worse than previously understood, according to a report of Climate Central, an independent organization of leading scientists and journalists researching and reporting the facts about the changing climate and its impact on the public. Climate Central surveys and conducts scientific research on climate change and informs the public of key findings. New elevation data shows that by mid-century, frequent coastal flooding will rise higher than areas currently home to hundreds of millions of people, the report says.  As a result of heat-trapping pollution from human activities, rising sea levels could, within three decades, push chronic floods...

The Sun Shines on Nautical Charts in Different Ways

Just recently someone reminded me about the 20th anniversary of the finalization of the first official type-approval of an ECDIS device. Indeed, it was in summer 1999 that all sea trials and technical tests at the labs of the Federal Maritime and Hydrographic Agency of Germany were completed and, being in charge of this process at the time, I signed the official certificate to confirm that the Transas Navisailor device met all applicable IMO and IHO standards. We did our best to confirm software stability and physical robustness of the device based on the very small range of S-57 ENCs... (read more)

Live Transmissions from the Deep

Exploring the World’s Most Unknown and Least Protected Ocean
Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located. Furthermore, researchers are often using advanced instruments that have never... (read more)

Shipwreck Monitoring in the North Sea

Surveyors Discover World War One Submarine
In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its homeport of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine.

In July 2019, research vessel MS Arca left its home port of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine.  As an executive agency of the Dutch Ministry of Infrastructure and Water Management, Rijkswaterstaat facilitates smooth and safe maritime traffic in the Dutch North Sea. One of its activities is an annual seabed monitoring programme. Apart from a few deeper spots, the Dutch part of the North Sea is in general 35 metres deep, while the coastal... (read more)

How Will First Responders Deal With Oil Trapped Under Ice?

Video Included
As sea ice continues to melt in the Arctic and oil exploration expands in the region, the possibility of an oil spill occurring under the ice is higher than ever, says the Woods Hole Oceanographic Institution (WHOI).  But how first responders will deal with oil trapped under ice in such an extreme and remote environment is a huge, unresolved question. “With the opening of the Northwest Passage a few years ago and more commercial ships routinely travelling through the area, there have been concerns among various government agencies that there’s no real infrastructure in place to respond to an oil...

Bubble Barrier Could Prevent Plastics from Entering the Oceans

Video Included
A Dutch company says it has found a bubble-based solution for the tonnes of plastics that enter the oceans from rivers and canals. The company produces a bubble screen by pumping air through a tube with holes in it, which is located on the bottom of the waterway. The Bubble Barrier, as the system is called, creates an upward thrust, which brings waste to the surface of the water. Positioned diagonally in the waterway, the Bubble Barrier uses the natural current to guide the plastic to the catchment system at the riverside. Ships and fish can bypass the barrier, but...

MSI Provides Metocean Data to Support Construction of Breakwater

MSI, a company that provides meteorological and oceanographic (metocean) measurement services, was recently contracted to install a range of equipment for a period of between 2 and 4 months in the Moroccan port of Laayoune. The city of Laayoune is a hub for fishing and for phosphate mining in the region.As part of port expansion plans, contracting company Archirodon was awarded an EPC contract which includes the construction of a new 950m breakwater. Part of the breakwater will act as a quay structure for the berthing of vessels to provide loading/unloading facilities of solid and liquid bulk. Other infrastructure that... (read more)

Significant Changes in Wave Conditions Due to Climate Change

Research finds that a warming planet will also alter ocean waves along with more than 50% of the world’s coastlines. This study, published in Nature Climate Change, reports significant implications for coastal flooding and erosion. As part of the Coordinated Ocean Wave Climate Project, ten research organisations, including the British National Oceanography Centre (NOC), combined to look at a range of different global wave models in a variety of future climate scenarios, to determine how waves might change in the future. "We are proud to be involved in this worldwide collaboration in wave science: this paper helps us to understand and quantify the... (read more)

Old Fashioned or Just Safe

Not long before this issue of Hydro International went to press, a major problem with Galileo, the European equivalent of the American GPS system, occurred. A few days later, the malfunctioning system has still not been corrected. It appeared to be an incident related to the Galileo ground infrastructure that resulted in a temporary interruption of the Galileo Initial Services. Disrupted Hydrographic and Oceanographic Operations Galileo is widely used by most of the commercially available receivers. Multi-constellation GNSS receivers will remain unaffected and compute position and timing using other constellations, said experts for the European GNSS Agency, the industry, the... (read more)
