Things are heating up at the seafloor.

Thermometers moored at the bottom of the Atlantic Ocean recorded an average temperature increase of about 0.02 degrees Celsius over the last decade, researchers report in the Sept. 28 Geophysical Research Letters. That warming may be a consequence of human-driven climate change, which has boosted ocean temperatures near the surface (SN: 9/25/19), but it’s unclear since so little is known about the deepest, darkest parts of the ocean.

Free-floating Crinoids, a.k.a. feather stars, are mesmerizing deep-sea creatures that dance in water like stars dance around a black hole: that is to say, gracefully. The smooth-moving feather stars ribbon their limbs through the ocean for motive force, and put on an entrancing show while doing so. The one in the clip immediately below, for example, may possess you with its bizarre fluidity.

Last October, a team of marine explorers sent Hercules — a remote-controlled vehicle — to the bottom of the ocean. Its mission: to visit an octopus neighborhood. It was off the coast of central California, near an undersea volcano. Late one night, after scanning a long stretch of empty seafloor, Hercules’ spotlight and camera revealed a parade of curious creatures. First was a slender bottom-feeder called an eelpout. It was half-buried in the sediment. Then came a sea pig — a squishy thing that looks like a living pink balloon, but with tentacles.

The Great Barrier Reef has been having a rough year. Warm waters have led to record coral bleaching this year and could hasten the reef’s die-off. But while surface corals are suffering, nearly a mile beneath the surface, deep-sea corals near the Great Barrier Reef are thriving.
