New Algorithm Could Simplify Decisions for Ship Channel Dredging

A new decision-support tool could become a game changer in the dredging of ship channels. Millions of dollars are at stake every time a major ship channel is cleaned up. Delays in dredging can cost even more by triggering increased risks, repeated maintenance and lost revenue. In either case, the task cannot be put off indefinitely.All ship channels must be regularly cleared of sand, debris settled on the bottom (called shoal) and miscellaneous trash.

They Say We Know More About the Moon Than About the Deep Sea. They’re Wrong

We know more about the Moon than the deep sea.This idea has been repeated for decades by scientists and science communicators, including Sir David Attenborough in the 2001 documentary series The Blue Planet. More recently, in Blue Planet II (2017) and other sources, the Moon is replaced with Mars.As deep-sea scientists, we investigated this supposed “fact” and found it has no scientific basis. It is…

Fiber Optic Sensing and Mining an Ocean of Data

Fiber optic sensing is opening up vast new areas of research and data gathering potential, not least across our oceans, where existing cables could offer a new global sensing network. Elaine Maslin reports.Criss crossing between our nations, across channels and between continents are a multitude of cables – some 120 million km of them. Some are pretty old (the first international submarine cable was laid across the Channel, between the UK and France, in 1850).
