What prevents the majority of scientists from making the leap from the ivory tower to the front lines?
By Stuart Campbell and Nils Krueck
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.
After years of anticipation an NG Explorer finally gets to swim among the unusual corals at the bottom of South America’s fjords.
Follow along as NG Grantee Rhian Waller explores the little known world of corals that dwell in the fjords of South America.
When I think of luminosity I think of the brightness of the sun or associate it with technology, light bulbs, light emitting diodes, and of course, the energy sources that make it possible. In many ways, creating light has promoted the “nightlife” or our ability to see, signal, and interact in darkness. Just a trip…
To truly convey what’s at stake in these unique deep-sea ecosystems, the Pew Environment Group recently put together a short video featuring many visually-stunning images of deep-sea life, as well as the barren aftermath left by high-seas bottom trawlers that have dragged their heavy nets and weights across the ocean floor. Scientists attest that this fishing method is the single most destructive fishing activity currently occurring on the high seas.
