Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.

High CO2 to slow tropical fish move to cooler waters

February 8, 2021 sarah Jonas Climate Change, fish, Marine, Ocean Acidification

Under increasing global warming, tropical fish are escaping warmer seas by extending their habitat ranges towards more temperate waters. But a new study shows that the ocean acidification predicted under continuing high CO2 emissions may make cooler, temperate waters less welcoming.

Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future.

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study.

Ocean acidification causing coral ‘osteoporosis’ on iconic reefs

August 27, 2020 sarah Jonas Climate Change, Corals, Ocean Acidification, Osteoporosis

Scientists have long suspected that ocean acidification is affecting corals’ ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which also influence coral growth. New research from the Woods Hole Oceanographic Institution (WHOI) reveals the distinct impact that ocean acidification is having on coral growth on some of the world’s iconic reefs.

Protecting bays from ocean acidification

June 12, 2020 sarah Jonas Ocean Acidification

While there was a bay-wide decline of submerged aquatic vegetation (SAV) from the 1960s through the 1980s, restoring these once-abundant SAV beds has been a primary outcome of efforts to reduce loads of nutrients and sediments to the estuary and SAV cover has increased by 300 percent from 1984 to 2015. One of the largest recovered SAV beds lies in an area of the bay known as the Susquehanna Flats—a broad, tidal freshwater region located near the mouth of the Susquehanna River at the head of the bay.

University of Delaware professor Wei-Jun Cai teamed with the National Oceanic and Atmospheric Administration (NOAA) scientists, as well as professors and professionals from numerous research institutes, to conduct an in-depth study that looks at carbon dioxide uptake and ocean acidification in the coastal oceans of North America.

Ocean acidification impacts oysters’ memory of environmental stress

Researchers from the University of Washington School of Aquatic and Fishery Sciences have discovered that ocean acidification impacts the ability of some oysters to pass down “memories” of environmental trauma to their offspring.

A new study finds that a nuclear war could throw the world’s ocean chemistry for a loop—and coral reefs could pay the price.
