  1. 💁🏻‍♀️ TIL: 🛸🌊 A #NOAA #ROV explores abyssal plains near the #CookIslands in the #SouthPacific, mapping the deep seafloor and #water column with sensors while live streaming nearly daily through August 13. Divers have already spotted carnivorous #sponges that capture small #crustaceans, a surprising find for habitats once thought sparse.

    Out of the blue: Hyperaccumulation of molybdenum in the Indo-Pacific sponge Theonella conica science.org/doi/10.1126/sciadv

    "Entotheonella serves as a detoxifying organ for accumulating metals inside the body of its #sponge hosts. Hoarding more and more molybdenum, the bacteria convert it from its toxic soluble state into a mineral."

  3. Have we misinterpreted pre-industrial temperature baseline?

    Earth may have warmed on average by at least 1.7°C since pre-industrial times. This suggests we have passed the 1.5°C goal of the Paris Agreement. Says a new study based on gauging ocean temperatures over past centuries, called “sclerosponge thermometry”.

  4. So I started with 3g of sediment and this is what I have left after an acid bath in HCl to get rid of carbonates, separating out the clays, baking the organics out at 500 degrees C and separating out the silica 😳 But it’s ok! Gonna have lots of microfossils to look at! #phytoliths #sponges #diatoms #microfossils #PalaeoenvironmentalReconstruction #Science
