    Ancient humans may have deliberately voyaged to Japan’s Ryukyu Islands

    Satellite-tracked buoys suggest that long ago, a remote Japanese archipelago was reached by explorers on purpose, not accidentally.

    With Theta, 2020 sets the record for most named Atlantic storms

    Climate change is expected to fuel fewer — yet more intense — Atlantic storms. With a whopping 29 storms but few strong ones, 2020 may be an outlier.

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

    Deep-sea temperatures seem to be rising, but it’s too soon to say whether that’s a result of climate change caused by humans, researchers say.

    Large-scale changes in Earth’s climate may originate in the Pacific

    A new study suggests that the melting of Alaska’s glaciers into the North Pacific could have far-ranging effects on ocean circulation and the climate.

    Underwater earthquakes’ sound waves reveal changes in ocean warming

    A new technique uses the echoes of earthquakes in seawater to track the impact of climate change on the oceans.

    Climate

    Bering Sea winter ice shrank to its lowest level in 5,500 years in 2018

    Peat cores that record five millennia of climate shifts in the Arctic region suggest recent ice loss is linked to rising carbon dioxide levels.

    Species may swim thousands of kilometers to escape ocean heat waves

    A new analysis of ocean heat waves shows latitude matters when it comes to how far fish and other sea species must go to find cooler waters.

    Predictions for the 2020 Atlantic hurricane season just got worse

    Wind patterns and abnormally warm seawater are conspiring to create especially hurricane-friendly conditions in the Atlantic.

    These ancient seafloor microbes woke up after over 100 million years

    Scientists discover that microbes that had lain dormant in the seafloor for millions of years can revive and multiply.

    Neon colors may help some corals stage a comeback from bleaching

    When some corals bleach, they turn bright colors. Stunning hues may be part of a response that helps the corals recover and reunite with their algae.

    Deep-sea mining may damage underwater ecosystems for decades

    Microbe communities in the seabed off Peru still haven’t fully recovered from being disturbed by a deep-sea mining experiment 26 years ago.
