There are clues to the near-future behaviour of a warming Greenland, and perhaps even a warming Antarctic, buried under the North Sea.

Look below its bottom muds and you will find immense valleys. Hundreds of them.

They were carved by rivers of meltwater running beneath the ice sheet that covered Northern Europe towards the end of Earth's last major cold phase.

We've known about these valleys (often called "tunnel valleys" because they were incised under the ice sheet) for some time, but only in recent years has their true scale become apparent.

Modern seismic (sound wave) data gathered by oil and gas prospectors has brought a new clarity that has enabled scientists to study the hidden features in greater detail.

The Nippon Foundation-GEBCO Seabed 2030 Project has just over nine years left to achieve its indispensable goal of the definitive, freely available map of the entire world ocean floor. The Project’s timeline is ambitious but vital – in 2019, we were warned that we only have 11 years left to prevent irreversible damage from climate change[1]. The United Nations Climate Change Conference (COP26) reminded us of the commitments that must be made on a global scale if we are to safeguard the future of our planet, and certainly Seabed 2030 is operating on that global scale.

Environmental Impact

Our oceans drive global systems that make the Earth habitable for humankind, with the UN even describing the oceans as ‘our planet’s life support’.

The National Hurricane Center has recently expanded and provided more detail in its Offshore Zone forecast product, in order to provide better service for the Blue Water mariners.

Overview:  The Tropical Analysis and Forecast Branch (TAFB) of the National Hurricane Center (NHC) has been issuing plain text marine forecasts for a configuration of 32 offshore zones in the Gulf of Mexico, Caribbean Sea, and much of the Atlantic Ocean south of 31N and west of 55W since 2011. At that time, the zones were designed to offer adequate forecast precision while limiting the number of zones as much as possible. Several

The Earth has five oceans, right? There’s the Atlantic, Pacific, Indian, Arctic, and Southern Oceans. Even the Southern Ocean is relatively new so you may have learned that Earth only has four. But now we have evidence of water deep inside the planet, too. A lot of water in fact—potentially more than the volume of all of the oceans we already know about combined. Scientists confirmed the presence of water thanks to a diamond found in Botswana. The gem originated more than 400 miles deep in the Earth and has tiny little imperfections from minerals and water from that deep layer inside the planet where it formed.

Oxford University researchers are playing a key role in the first systematic survey of ocean life in the Maldives, from the surface to 1,000 metres deep. This will enable the Maldivian government to develop conservation and sustainable development policies so that the oceans continue to protect and provide for the Maldivian people.

Taking place between 4 September and 7 October, the Nekton Maldives Mission will deploy two of the most advanced human-occupied submersibles, which make use of robotic and autonomous systems and more than a dozen research technologies. This will make it one of the most technically varied and advanced missions ever undertaken in the Indian Ocean.
