Co-authored by Erica Cirino Scientists have known for about 15 years that ocean acidification has made it more difficult for hard corals and shelled marine organisms to survive. To grow, hard corals as well as clams, oysters, and others pull calcium and carbonate molecules out of the water and join them together to create calcium…
I’m writing this in the high Arctic at 78º North Latitude in early July, aboard Greenpeace’s Arctic Sunrise where I’m a guest for a few days, with 24-hour daylight and gleaming glaciers in the valleys of snow-capped coastal mountains. We’re here because shrinking sea ice and warming ocean water is moving fish farther north, and…
New research on tropical coral reef ecosystems showed that releasing larvae more often is beneficial for a species’ network. The study on reproductive strategies is critical to assess the conservation of coral reef ecosystems worldwide. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science used a computer model developed by…

With colleagues from WCS (Wildlife Conservation Society), we recently surveyed the first community-led Marine Protected Areas (MPAs) in Madagascar. These areas provide genuine hope for coral reef conservation and small-scale fisheries management under the shadow of emerging oil and gas development, deforestation, illegal fishing and climate change.
What prevents the majority of scientists from making the leap from the ivory tower to the front lines?

The Forgotten Islands occupy a region in the southeastern Indonesian province of Maluku, a sparsely-populated area covering about 50,000 square kilometers that includes a vast expanse of coral reefs. As the region’s name suggests, not much is known about these reefs and their associated fisheries. One important reason for this is that for much of the year the seas are wild and unable to be accessed. Another reason is that Maluku’s Forgotten Islands support around 70,000 people who practice traditional customs that hark back to before the conversion of communities to Christianity. These customs include the guarding of marine resources against occasional visitors, such as nomadic fishers from central Indonesia
This post is the last in the Click! Click! Click! Series which profiles interesting photographic moments that Kike captures during his travels. This photograph shows the process known as fluorescence. Some organisms bioluminescent, like corals that absorb one color and emit another. This outgoing light is of a longer wavelength than the incoming. One form of energy is converted into another. If you like this…

Protected areas are a hallmark strategy in marine conservation. Yet when they were first created, a growing lethal threat had not yet fully revealed itself. Warming, acidifying, and rising seas have devastated the world’s sensitive coral reefs, widely regarded as “ground zero” for climate change. El Niños and marine heat waves can bleach and destroy vast areas of healthy, biodiverse reefs even where they occur within “protected” parks. If the global impacts of climate change do not stop at park boundaries, what can scientists do? One strategy is to identify and protect climate refuges – habitats with more stable environments where species can survive warming temperatures.
Written by Manu San Félix The other day, Alan Friedlander wrote that “these reefs are like windows into the past.” He was right; diving here is like taking a time machine back to an age when the ocean had no human impact and was full of sharks, tunas and groupers. A time when the marine…
Follow Dr. Rhian Waller and colleagues this January into the Southeastern Alaskan fjords on the last expedition of the series to understand more about the unique corals that live here.
We’ve heard of coral dying, but did anyone imagine that dead humans could contribute to keeping reefs alive?
Coral reefs off Curacao in the south Caribbean Sea (Paul Selvaggio 2012) Hello everyone, this is Mark Schick, the Special Exhibits Collection Manager at Shedd Aquarium. I wanted to share a trip report from our latest coral conservation trip with the SECORE Foundation. The SECORE Foundation uses knowledge from coral scientists and aquarium professionals to…
The Caribbean’s coral reefs have collapsed, mostly due to overfishing and climate change, according to a new report released by the International Union for Conservation of Nature (IUCN).
In search of deep-sea corals that live much shallower in Patagonian fjords, Rhian Waller has spent weeks diving in frigid waters. Follow her account of the expedition’s final days and the work that’s still ahead.
Follow along as NG Grantee Rhian Waller explores the surprisingly diverse corals that dwell deep in the fjords of the southern tip of South America, and discover what they can tell us about the rest of the ocean as well.
