Global Sea-level Rise Has Been Accelerating Since 1960

The recent acceleration in global sea-level actually started in the 1960s, around three decades earlier than previously thought, according to a recent publication of the National Oceanography Centre (NOC). The results of the study form part of the NOC’s ongoing research into sea-level rise, which revealed last year that rising sea levels could cost £11 trillion worldwide annually by 2100, if the target of holding increasing global temperatures within 2ºC of pre-industrial levels is missed. The findings have been published in the Nature Climate Change journal and involve NOC scientists. Led by the University of Siegen in Germany, this study is the first to put... (read more)

Lost 52 Project Discovers the Bow of WW II Submarine 'Grunion'

Video Included
Tim Taylor and his team of the Lost 52 Project have identified the bow of the USS Grunion. It was discovered about a quarter of a mile from the main wreckage. In October 2018, the Lost 52 Project team returned to the site of the main wreck and found that the ship's bow had slid down a steep volcanic embankment. The submarine went missing about a month after it departed on its first war patrol in 1942. It wasn't seen again until the sons of the Grunion's commanding officer began searching for it and found the wreckage in 2007 off the... (read more)

La Minerve, Vanished in 1968, Discovered off Toulon

The French navy has located La Minerve, one of its submarines that disappeared more than 50 years ago. Onboard were 52 crewmembers.  The submarine was discovered on the seabed at a depth of 2,370 metres, 27 miles (45km) off the port of Toulon, the home of a French naval base in the Mediterranean. In January 1968 the submarine disappeared whilst on a military exercise. Until now repeated searches have failed to find the vessel. A senior French naval officer told Agence France-Presse the submarine was discovered by the Seabed Constructor, a subsea support and construction vessel of the US company Ocean Infinity. The submarine... (read more)

Annual Entrepreneurs Forum on Marine Robotics

The marine robotics industry is growing, new companies are being created weekly and investors are waking to the opportunities in the ocean domain. Technology created in diverse markets such as additive manufacturing, autonomous cars, and consumer robotics is being deployed to change how we design, build and use robots. The growth in the marine sector is tied to increasing human activity in the ocean. Robotic technologies and techniques are going mainstream in science, defence, and industry. The Forum in July will help frame the challenges facing the industry and offer a road map to accelerate progress. The theme this year... (read more)

Resolutions of the IHO

The year 2019 sees the centenary of the first Hydrographic Conference which took place in London in the summer of 1919. Only one year after the end of the First World War, representatives from 26 countries met in London at Trinity House to discuss and agree on future technical cooperation in hydrography. The report of the proceedings starts with the following statement: 'The experiences of the war in special relation to hydrographic matters showed most clearly the enormous importance of the possession of accurate charts and hydrographic information generally, and the very grave disadvantage attendant on their no-possession; and also...

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)

Tidal Energy Plant Gets Smarter with Data Intelligence Platform

Sabella, a pioneering tidal and ocean stream turbine developer, has partnered with QOS Energy to improve the performance monitoring of its ground-breaking Ushant tidal energy project. The first 1MW tidal turbine of the plant, immersed 55m underwater off the west coast of France, is equipped with more than 100 sensors gathering data every 5 minutes. It now uses QOS Energy’s powerful data intelligence platform to identify, assess and anticipate potential failures. Sabella’s 1MW D10 turbine was initially commissioned in 2015 in the Fromveur Passage, a strait that lies between Ushant Island and the Molène archipelago, off the coast of the... (read more)
