Off the back of the last post, here is an interesting article from the Washington Post on the discovery of deep sea reefs in Hawaii. Deep reefs (‘mesophotic’ coral reefs) exist at the edge of the photic zone (upto 150m depth) and are still dependent on light. These are fascinating ecosystems that to date have … Continue reading Deep sea coral reefs discovered in Hawaii
Here is some good news from the Caribbean – despite a >95% decline in staghorn coral since the 1970’s, there are some signs of resurgence: Dropping 12 feet below the ocean’s surface less than a mile off Fort Lauderdale’s beach-front towers, a diver might wonder if he or she somehow got magically transported to a … Continue reading Signs of resilience and recovery from the coral reefs of Florida
So it’s that time of year again in the Caribbean where the corals undergo the annual mass spawn. Along with this ritual comes the coral researchers, who run a bunch of experiments with coral recruitment, settlement, fertilization, which involves catching coral sperm and eggs using nets (see above) and mixing it all up in jars … Continue reading Live blogging the annual coral spawning event across the Caribbean
John Bruno mentioned this in passing at the bottom of his last post (Climate Literacy), but I thought this deserved a post of it’s own. Check out JB’s blog over at his lab website, bought to you live from the Galapagos Islands – shark surveys, coral monitoring, marine iguanas, seals on the rocky intertidal shores… … Continue reading Blogging from the Galapagos Islands
The 7000-year-old coral communities of Moreton Bay are telling a curious tale, expanding when sea-levels rise or water quality improves, then declining when current circulation becomes more restricted. Intriguing new insights into the behaviour of corals and fish under changing climatic conditions will be presented by leading marine researchers at a public forum in Brisbane … Continue reading 7000-year-old corals of Moreton Bay tell their story
CNN News, May 29th 2009: Advances in the study of coral in the last few years has led a group of scientists to conclude that corals almost rival humans in their genetic complexity and their relationship to algae is key to their survival. “We’ve known for some time the general functioning of corals and the … Continue reading Coral almost as genetically complex as humans’
I remember seeing a fascinating presentation by Mahmood Riyaz on the reef slope failure of this coral reef at the ICRS conference in Florida last year – how the atoll rim was cracking due to the sheer amount of construction and concrete. Welcome to Male, the capital of the Maldives, where >100,000 people are crammed … Continue reading The worlds most overpopulated coral reef?
