Global Ocean Temperatures Reached Record High in 2024

Global sea temperatures reached an all-time high in 2024, according to a new study published Friday in the journal Advances in Atmospheric Sciences.  The 54 researchers from seven countries deployed thousands of instruments to collect ocean data both at the surface and up to 2,000 meters below the surface — the latter called ocean heat […]

    Deep-Sea Mining 101: Everything You Need to Know

    Quick Key Facts What Is ‘Deep-Sea Mining’? Deep-sea mining is the process of retrieving mineral deposits from the ocean floor using destructive methods such as dredging, drilling and hydraulic pumps. These methods disrupt and harm marine life and their ecosystems. The seabed is a largely unexplored world of unidentified species and mystery. The Clarion-Clipperton Zone […]

    Right Whales Can Live 130 Years or Longer, Research Finds

    Scientists have estimated that bowhead whales — the longest-living whale species — can live more than 200 years. It was once thought that the bowhead’s cousin, the right whale, had an average lifespan of about 70 to 80 years, but new research has revised that estimate to more than 130 years — nearly twice as […]

    A Marine Heatwave Killed 4 Million of Alaska’s Murre Seabirds

    A Marine Heatwave Killed 4 Million of Alaska’s Murre Seabirds

    Beginning in late fall 2014 and lasting into 2016, an anomalous, massive marine heatwave nicknamed “the Blob” developed off the western coast of the U.S., covering all of Alaska’s coastwater and extending as far south as Southern California, raising ocean temperatures by several degrees Celsius. The Blob had an extreme effect on Alaska in particular. […]

    New Microplastics Water Filter Made With Cotton and Squid Bone Could Be 99.9% Effective, Scientists Report

    New Microplastics Water Filter Made With Cotton and Squid Bone Could Be 99.9% Effective, Scientists Report

    In a new study led by researchers at Wuhan University, scientists have developed a filter, made with cotton and squid bone, that can be used to adsorb certain microplastics in aquatic environments. Further, they determined the filter was about 98% to 99.9% effective in filtering microplastics. The study, published in the journal Science Advances, explored […]
