Even the deepest, coldest parts of the ocean are getting warmer

    Thermometers moored at the bottom of the Atlantic Ocean recorded an average temperature increase of about 0.02 degrees Celsius over the last decade. That warming may be a consequence of human-driven climate change, which has boosted ocean temperatures near the surface, but it’s unclear since so little is known about the deepest, darkest parts of the ocean.
    “The deep ocean, below about 2,000 meters, is not very well observed,” says Chris Meinen, an oceanographer at the U.S. National Oceanic and Atmospheric Administration. The deep sea is so hard to reach that the temperature at any given research site is typically taken only once per decade. But Meinen’s team measured temperatures hourly from 2009 to 2019 using seafloor sensors at four spots in the Argentine Basin, off the coast of Uruguay.
    Temperature records for the two deepest spots revealed a clear trend of warming over that decade. This warming is much weaker than in the upper ocean, Meinen says, but he also notes that since warm water rises, it would take a lot of heat to generate even this little bit of warming so deep.
    It’s too soon to judge whether human activity or natural variation is the cause, Meinen says. Continuing to monitor these sites and comparing the records with data from devices in other ocean basins may help to clarify matters.

How octopuses ‘taste’ things by touching


   Octopus arms have minds of their own. Each of these eight supple yet powerful limbs can explore the seafloor in search of prey, snatching crabs from hiding spots without direction from the octopus’ brain. But how each arm can tell what it’s grasping has remained a mystery.

   Now, researchers have identified specialized cells not seen in other animals that allow octopuses to “taste” with their arms. Embedded in the suckers, these cells enable the arms to do double duty of touch and taste by detecting chemicals produced by many aquatic creatures. This may help an arm quickly distinguish food from rocks or poisonous prey, Harvard University molecular biologist Nicholas Bellono and his colleagues report online October 29 in Cell.

   The findings provide another clue about the unique evolutionary path octopuses have taken toward intelligence. Instead of being concentrated in the brain, two-thirds of the nerve cells in an octopus are distributed among the arms, allowing the flexible appendages to operate semiindependently.
