"Environmentalists in Mexico have fought the recent relocation of a coral reef to make way for bigger ships in the Port of Veracruz. They worry about the ecosystem impacts of the port expansion and the precedent it sets for uprooting corals."
"The year before Hurricane Harvey, the Flower Garden Banks corals were hit twice: once with an onslaught of freshwater from Texas and then extreme sea surface temperatures that led to one of the worst coral bleaching events on record."
"News about coral reefs seems almost unrelentingly bleak. Everywhere they’re bleaching and collapsing, unable to withstand the ravages of fast-heating waters — except, that is, the northern Red Sea, where it appears that a vast region of exceptionally hardy reefs will survive temperatures far exceeding present-day norms."

"Albright and her colleagues created a huge inflatable container that would rise from the ocean floor and trap 15,000 liters of seawater, “like submerging a bucket underwater and pulling it up,” she says. They then used a ring of air diffusers, much like those that send bubbles into aquarium tanks, to saturate the trapped water with carbon dioxide. This gas acidified the water, which Albright then pumped over a nearby patch of corals, simulating what these creatures will experience 100 years from now."

"As a way of understanding which factors had the biggest impacts on Hawaii’s corals, a group of researchers from the collaborative Ocean Tipping Points project, co-led by Larry Crowder, the Edward Ricketts Provostial Professor of Marine Ecology and Conservation at Stanford’s Hopkins Marine Station and senior fellow at the Stanford Woods Institute for the Environment, completed the first-ever comprehensive map of how both humans and natural events influence overall reef health. This new study was published March 1 in PLOS One."

"How the coral, algae, and microbes work together is uncertain. The discovery adds yet another layer of complexity to the already difficult task of figuring out how to protect coral from climate change."
"On show at Verve Cafe the images in Views from the Trophy Room are montages of the Gisborne artist’s paper mache coral clusters that colonise the walls and workbenches of his tin shed studio."
"Bleaching doesn’t necessarily kill coral, though it does turn it an eerie bone white. A type of photosynthetic algae called zooanthellae lives in the tissues, producing nutrients and carbon that the coral uses for energy. The symbiotic algae also give corals their stunning colors. When coral undergoes stress from pollution, loss of light, or increasing water temperatures, the zooanthellae are ejected, causing the coral to lose its color and food supply. If things go back to normal relatively quickly, the algae can often recolonize the coral and the system survives."
"The ecological impacts of repeated ocean warming remain poorly understood in the Galápagos, as they do for many of the world’s coral reefs. The geography of bleaching, recovery and resistance to warming water is virtually unknown because monitoring is very limited."
