Ocean acidification a big problem — but not for coral reef fish behavior

A comprehensive multi-year project challenges previous findings Norwegian University of Science and Technology A three-year, comprehensive study of the effects of ocean acidification challenges previous reports that a more acidic ocean will negatively affect coral reef fish behaviour. The study, conducted by an international coalition led by scientists from Australia and Norway, showed that coral…

Reef Alarmists Jump The Shark

by Walter Starck (with thanks to Dr. Bob Carter) The Great Barrier Reef is doomed again. A recent widely publicised scientific study reports the dramatic finding that it has lost half its coral in the last 27 years. Forty-eight precent of the loss is attributed to storm damage, with bleaching and crown-of-thorns starfish being responsible…

Six Easy Steps for Saving the Coral Reefs for our Grandchildren

Sea cucumbers: Dissolving coral reefs?

From the Carnegie Institution  and Stanford University comes word of this paper in JGR. Washington, D.C. — Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research led by Carnegie’s Kenneth Schneider analyzed the role…

Barrier reef panic? – not so much

It seems that when you look at the way the data was gathered, and find that while some areas of the GBR declined, others gained. Analysed other ways, it doesn’t seem so alarming. Perhaps the phrase is “coral picking”? Assessing loss of coral cover on the Great Barrier Reef: A response to Hughes et al.…
