  • The Ocean Is Losing Its Breath

    In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms.

  • New Study Identifies Thermometer for Global Ocean

    There is a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published in the Jan. 4, 2018, issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography and institutions in Switzerland and Japan detailed their…

  • Scripps Scientists Use Photomosaic Technology to Find Order in the Chaos of Coral Reefs

    In a study published recently in Coral Reefs, scientists from Scripps Institution of Oceanography at UC San Diego created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll, and made surprising discoveries around coral spatial ecology. The scientists, led by graduate student Clinton Edwards, canvassed more than 17,000 square feet of reef, and 44,008…

  • Rising CO2 Leading to Changes in Land Plant Photosynthesis

    Researchers led by Scripps Institution of Oceanography at the University of California San Diego have determined that major changes in plant behavior have occurred over the past 40 years, using measurements of subtle changes in the carbon dioxide (CO2) currently found in the atmosphere.The two main isotopes, or atomic forms, of carbon are carbon-12 (12C)…

  • Primordial Black Holes May Have Helped to Forge Heavy Elements

    Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis.As the late Carl Sagan once put it: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon…

  • Study finds toxic pollutants in fish across the world's oceans

    A new global analysis of seafood found that fish populations throughout the world's oceans are contaminated with industrial and agricultural pollutants, collectively known as persistent organic pollutants (POPs). The study from researchers at Scripps Institution of Oceanography at UC San Diego also uncovered some good news?concentrations of these pollutants have been consistently dropping over the…
