Can Acid Neutralizers Help Coral Reefs Bounce Back?

NPR

Coral reefs are in trouble worldwide, from a host of threats, including warming ocean temperatures, nutrient runoff and increasing ocean acidity. A noted climate scientist from California has been conducting an experiment on Australia's Great Barrier Reef to see whether antacid could boost coral growth.

Increased Carbon Dioxide Levels Damage Coral Reefs

NPR

Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades.

Scientists Seek Sea Urchin's Secret to Surviving Ocean Acidification

Scientists Seek Sea Urchin's Secret to Surviving Ocean Acidification

Science Daily

Stanford scientists have discovered that some purple sea urchins living along the coast of California and Oregon have the surprising ability to rapidly evolve in acidic ocean water -- a capacity that may come in handy as climate change increases ocean acidity. This capacity depends on high levels of genetic variation that allow urchins' healthy growth in water with high carbon dioxide levels.

The study, co-authored by Stephen Palumbi, a senior fellow at the Stanford Woods Institute for the Environment and director of Stanford's Hopkins Marine Station, revealspreviously unknown adaptive variations that could help some marine species survive in future acidified seas.

Crabs, supersized by carbon pollution, may upset Chesapeake’s balance

Crabs, supersized by carbon pollution, may upset Chesapeake’s balance

The Washington Post

It is the dawn of the super crab.

Crabs are bulking up on carbon pollution that pours out of power plants, factories and vehicles and settles in the oceans, turning the tough crustaceans into even more fearsome predators.

That presents a major problem for the Chesapeake Bay, where crabs eat oysters. In a life-isn’t-fair twist, the same carbon that crabs absorb to grow bigger stymies the development of oysters.

“Higher levels of carbon in the ocean are causing oysters to grow slower, and their predators — such as blue crabs — to grow faster,” Justin Baker Ries, a marine geologist at the University of North Carolina’s Aquarium Research Center, said in an recent interview.

Putting Larval Cobia to the Acid Test: Potential Resistance to Increasingly Acidic Oceans by Certain Species of Fish

Putting Larval Cobia to the Acid Test: Potential Resistance to Increasingly Acidic Oceans by Certain Species of Fish

Science Daily

Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is a source of concern for marine scientists worldwide. Studies on coral, mollusks, and other ocean denizens are helping to paint a picture of what the future might entail for specific species, should carbon emissions continue to increase.

In a new study published in Global Change Biology, University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science researchers Sean Bignami, Su Sponaugle, and Robert Cowen are the first to study the effects of acidification on the larvae of cobia (Rachycentron canandum). Cobia are large tropical fish that spawn in pelagic waters, highly mobile as they mature, and a popular species among recreational anglers.
