Expansive Study Shows Seagrass Meadows Can Buffer Ocean Acidification by Kat Kerlin March 31, 2021 Spanning six years and seven seagrass meadows along the California coast, a paper from the University of California, Davis, is the most extensive study yet of how seagrasses can buffer ocean acidification. The study, published today in the journal Global Change Biology, found that these unsung ecosystems can alleviate low pH, or more acidic, conditions for extended periods of time, even at night in the absence of photosynthesis. It found the grasses can reduce local acidity by up to 30 percent. “This buffering temporarily brings seagrass environments back to preindustrial pH conditions, like what the ocean might have experienced around the year 1750,” said co-author Tessa Hill, a UC Davis professor in the Department of Earth and Planetary Sciences and Bodega Marine Laboratory. ....

Washington, DC Algae colonizing dead coral are upending scientists ability to accurately assess the health of a coral reef community, according to new work from a team of marine science experts led by Carnegie s Manoela Romanó de Orte and Ken Caldeira. Their findings are published in Limnology and Oceanography. Corals are marine invertebrates that build tiny exoskeletons, which accumulate to form giant coral reefs. Widely appreciated for their beauty, these reefs are havens for biodiversity and crucial for the economies of many coastal communities. But they are endangered by ocean warming, seawater acidification, extreme storms, pollution, and overfishing. ....
