  • Coral reef experiment shows: Acidification from carbon dioxide slows growth
    on March 14, 2018 at 6:50 pm

    Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated. […]

    Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team of marine biologists just released 25 years of data about the health of Caribbean coasts. The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management. […]

  • Conserving coral communities
    on December 27, 2017 at 7:59 pm

    For years, people have sought to stop the loss of coral reefs by transplanting corals grown in underwater 'nurseries' to damaged reefs, but little work had been done to evaluate how effective such efforts were. A new study, however, suggests those projects have a positive impact on local fish populations, both in the short term and over time. […]

  • Can corals adapt to climate change?
    on November 1, 2017 at 6:17 pm

    Cool-water corals can adapt to a slightly warmer ocean, but only if global greenhouse gas emissions are reduced, a study has found. Some corals in the normally cool waters of the Cook Islands carry genetic variants that predispose them to heat tolerance. This could help the population adapt more quickly to rising temperatures. But they may not adapt quickly enough to outpace climate change. […]
