  1. If you spend any amount of time looking at maps of the ocean floor (and I do), you can't but notice the irregular blotches which are oceanic plateaus. Each of them tells a story of the Earth's interior.

  2. As Trump Promotes Critical Mineral #Mining, a Company Eyes the #Seafloor in Coastal #Virginia
    A proposed mining project off the #DelmarvaPeninsula is after minerals in heavy sands. Locals worry it would harm an important ecosystem.
    #KatieDawson, a commercial fisher, is worried that the ecosystem that supports her livelihood could be in jeopardy: A company wants to mine almost 2,500sq mi of the seafloor, an area larger than Delaware, 3-64 mi east of the Delmarva Peninsula.

    “🔍 For the first time, scientists have observed seafloor spreading in real time.
    Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges - a geological process that has shaped entire ocean basins over millions of years.
    During a research expedition in the Indian Ocean, scientists had just deployed a suite of instruments when a series of earthquakes triggered a seafloor spreading event, allowing them to observe the process as it unfolded.
    The findings offer rare new insights into how new oceanic crust forms and how the seafloor continues to evolve…”

    “Earth’s outermost layer - the crust - is constantly renewing itself. It’s broken into giant chunks called tectonic plates that pull apart, push against or slide past one another, creating grand geologic features.
    Underwater mountain ranges, or mid-ocean ridges, for instance, generally take shape where two tectonic plates are moving away from each other. Magma can then bubble up in between, solidifying and turning into new oceanic crust as part of a process called seafloor spreading. Although the phenomenon has created entire ocean basins, it remains quite mysterious because it happens so deep in the water.
    Now, for the first time, scientists have observed this dynamic activity happening in real time. They describe their findings - and their stroke of luck - in a study [link above], shedding light on a mechanism that made roughly two-thirds of Earth’s crust…”

  4. Squat lobsters, one species of which only eats wood, were discovered on the wreck of the #Endurance.
    “It is likely that this species is new to science, because it can withstand such low temperatures,” says Griffiths. “It could be a deep-sea species from elsewhere. Is it potentially something that will eat the wreck?”

  5. ‘The #Antarctic is the last frontier’: the quest to save #Shackleton’s #Endurance

    Amid fears the wreck will be more accessible to explorers – and new species – as the #climate warms, conservationists want to create the region’s first underwater protected area

  6. One of the most amazing projects I got to be part of is finally out! We now have a unified and comprehensive framework for #seafloor #geomorphology, which will, with a bit of luck, get us all to call things the same way. A major step forwards to be able to study the #ocean's floor consistently.

  8. #WeekendReading: Ye et al. about iron-bound organic matter under the #Seafloor in #ColdSeeps, there are some really interesting dynamics with how bioturbation seems to link into this, and it's far more than just a pairing with the sulphur cycling.

    The geology of the ocean floor is truly spectacular — perhaps even more than land geology. Unfortunately, it's really hard to study.

  10. What #Scientists Found When #DeepSeaMining Company Invited Them In
    An #ocean #mining company funded some of most comprehensive scientific studies to date, and peer-reviewed results have begun to emerge.
    Researchers from Natural History Museum in London analyzed samples from #seafloor before and after mining test and found number of worms, minute crustaceans and other animals in path of mining vehicle fell 37%. Variety of creatures declined by 32%.

  12. A new study provides scientists with a powerful new tool for monitoring and predicting #tectonic activity deep beneath the #seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.

  13. #Ocean is a #carbon toilet. Marine #heatwaves are clogging it
    As humans pump ever more carbon into sky, relentlessly raising ocean temperatures, worrying signals are flashing that this commode could be changing in profound ways. In 19th century just 2% of ocean experienced bouts of extreme temperatures, that figure is now well over 50%
    Tiny poops are supposed to sink to #seafloor, locking away carbon. But scientists have found that warm spells are disrupting that flushing

  14. An enormous but poorly understood region of the global ocean–referred to as the #abyssal benthic boundary layer–lies a few meters above the #seafloor and has only been sampled a handful of times.
