Ocean

A new study has laid bare the alarming reality of the impact of climate change on the oceans, with the analysis revealing the world's oceans were warmer in 2019 than any other time in recorded human history.

While autonomous underwater vehicles (AUVs) do make the gathering of oceanographic data easier, launching the things can still be a hassle. That's why scientists have developed a new system that uses an unmanned surface vessel to deploy an AUV.

It hasn’t been entirely smooth sailing, but The Ocean Cleanup is now calling an end to a first successful mission to collect plastic from the Great Pacific Garbage Patch, today showing off the first pile of captured trash on the shores of Vancouver.

An international team of researchers suggests that a wide variety of marine species could be used for monitoring the world's oceans. Using electronic tags, exploiting their natural behavior could fill gaps in our knowledge of the seas.

Take a walk along the canal in Amsterdam’s Westerdok district, and you may see an unsightly mess of waste gathered at the edge of the canal. What you’re seeing is the work of a new bubble barrier, designed to stop plastic waste flowing out to sea.

As far as fighting climate change is concerned, "one whale is worth thousands of trees," the IMF has said. But reports suggesting that trees therefore pale into insignificance compared to whales are missing the point.

Scientists have uncovered an unfortunate feedback loop that could make things worse for the climate. According to a new study, ocean acidification seems to increase the amount of nitrous oxide, a potent greenhouse gas, that’s released into the air.

About 65 million years ago, a huge asteroid slammed into the Earth and wiped out three quarters of all life on Earth, including the dinosaurs. Now, Yale researchers have found evidence that oceans became too acidic for marine animals to take.

A new long-term study has found high levels of antibiotic-resistant bacteria in wild dolphins, with rates growing over the last decade.

A huge raft of volcanic rock is floating towards Australia – and scientists say it'll help the ailing Great Barrier Reef.

​Famed American aviator Amelia Earhart disappeared in 1937, while attempting to fly around the world in a Lockheed Model 10E Electra. Now, a high-tech unmanned boat has been enlisted to help search for that plane, near an island where Earhart may have crash-landed.

Scientists at the University of Exeter have turned to Twitter for a better picture of the effect ocean plastics are having on sharks and rays. Summing these reports, they identified more than 1,000 individual sharks and rays seen entangled in ocean waste.
