The Delaware Aqueduct is the longest tunnel that is currently in use. It was completed in 1945 and is 85 miles (135 kilometers) long. Metro rail and rail tunnels in Asia and Europe have reached 37.5 miles long. The Channel tunnels is 31.3 miles long and has the longest underwater section. China is already building …
In 2016 and 2017, marine heat waves killed half of the corals in the Great Barrier reef. It takes ten years for the coral to recover. John Veron is the world’s top coral reef expert. Between a quarter and a third of all marine species everywhere has some part of their life cycle in coral …
Ocean Farm 1 is the world’s first deep-sea aquaculture farm. It is designed by leading salmon farmer SalMar ASA (of Norway). They paid China Shipbuilding Industry $300 million for six facilities. The first pilot system is 67 meters (220 feet high) and a diameter of 110 meters (football field length). It has the volume of …
China plans to increase the size of its marine corps from about 20,000 to 100,000 personnel to protect the nation’s maritime lifelines and its growing interests overseas. China is shifting brigades from the army to the Marines and Navy to shift from a land war focus to securing Belt and Road ports and other South …
Tiangong-1 was predicted to reenter the Earth’s atmosphere on April 2nd, 2018 00:30 UTC ± 1.7 hours. The reentry has been confirmed as 2018/04/02 00:16 UTC. Reentry occurred in the Pacific Ocean. Whatever remained of the craft fell in the South Pacific, between California and Hawaii — “out in the middle of nowhere, which is …

Nextbigfuture wrote about Nautilus Minerals several times since 2010. Nautilus Mineral is scaling up ocean floor mining. In January 2016, Nautilus Minerals took delivery of the three Seafloor Production Tools (SPTs) from SMD. The SPTs were shipped to PNG in April 2017 to undergo submerged trials. The trials are due to be completed in Q1 …
CSIRO has announced a partnership with San Francisco-based ocean technology start-up, Saildrone, to radically improve measurement and monitoring in Australian waters and the Southern Ocean. The research partnership over five years between Saildrone and CSIRO’s Oceans and Atmosphere group will see the deployment of state-of-the-art unmanned ocean surface vehicles, Saildrones, for the first time in …
Every day, 3800 robotic floats bob up and down, tracking temperatures in the world’s oceans, which sop up an estimated 90% of the heat from global warming. In the course of a decade, the international Argo array has provided one of the steadiest signatures of the effects of greenhouse gas emissions. But the floats go …
An international research team led by scientists at The University of Texas at Dallas and Hanyang University in South Korea has developed high-tech yarns that generate electricity when they are stretched or twisted. Researchers describe “twistron” yarns and their possible applications, such as harvesting energy from the motion of ocean waves or from temperature fluctuations. …
