, managed to dig a world record of 231 meters into the seabed at a depth of over 2,000 meters in the South China Sea on April 7, 2021. The success of Hainiu II made it much easier to explore methane hydrate, while preserving the proper temperature and pressure deep under the sea....
From this comparison we conclude that the range in possible geotherms at depths below 100 to 150 km under continents and oceans overlaps and that the thermal structure beneath an old stable continent is indistinguishable from that beneath an ocean were it at equilibrium. Oceans and continents are...
Such difficulties have related, for instance, to the transport of radioactive materials through coastal zones, adequate protection of underwater cultural heritage or the ways and means to conserve marine biodiversity. The resolutions have expanded in size and could be streamlined to highlight new ...
