Newly discovered “whale necropolis” enhances understanding of deep-sea ecology

Researchers from the Institute of Deep-sea Science and Engineering (IDSSE) of the Chinese Academy of Sciences, in collaboration with the University of Pisa, Italy, and the National Institute of Water and Atmosphere Research, New Zealand, have now documented the world’s deepest and largest known aggregation of whale fossils and active whale-fall ecosystems. This deep-sea site, referred to as a “whale necropolis” due to its vast size, is located in the Diamantina Zone of the southeastern Indian Ocean and contains evidence of cetacean falls for at least 5.3 million years.

Mining the ocean floor: 5 deep-sea sources of critical minerals essential to technology, and the fragile marine life at risk

Critical minerals are found in several forms in the ocean, from potato-size nodules to brine pools. They are also in some of the least understood parts of our planet.

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.

#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.
