Go check out these incredible photographs by National Geographic photographer Thomas Peschak of mantaray feeding frenzies in the Maldives. Apparently this swirling ‘cyclone‘ feeding behavior is rarely seen outside of the Maldives. Click here for a previous post on Climate Shifts for more details and video footage of Mantaray feeding behaviors. Continue reading “One-ton manta cyclonic feeding frenzy”
The Algalita Marine Research Foundation is on a 2 month voyage across the Pacific to study the concentration of plastics in the North Subtropical Gyre. This area has been known as the “Pacific Garbage Patch” due to the convergence of several ocean currents that drag garbage from all corners of the globe. Not only is … Continue reading Where Does It All Go? The ‘Pacific Garbage Patch’
If we don’t know our history, then we can’t know our future. Historians arguing the relevance of their subject often repeat that mantra. But one group of researchers is showing how true it is. Members of the History of Marine Animals Project (HMAP) believe that scrutinizing the minutiae of historical documents is the key to protecting our oceans for generations to come. Continue reading “Future protection of the oceans could lie in the past”
The paradigm of ‘coral vs algae’ has become entrenched in coral reef science over the last few decades. The classic example of this paradigm in the Caribbean was from a paper published byTerry Hughes in a 1994 article in the journal Nature, entitled “Catastrophes, Phase Shifts and Large-Scale Degradation of a Caribbean Coral Reef”. The … Continue reading Testing the ‘macroalgal dominated coral reefs’ paradigm
A recent study published by Tom Oliver and Stephen Palumbi from Stanford University in the journal ‘Marine Ecology Progress Series‘ seems to suggest yet another miraculous and novel mechanism by which corals will ‘escape’ the pressures of global warming. In a nutshell, the researchers found that corals from ‘warm pools’ at Ofu Island (American Samoa) … Continue reading Why the existence of ‘heat tolerant’ corals does not mean that coral reefs will be able to resist climate change.
The megamouth shark (Megachasma pelagios) is one of the worlds rarest sharks – spotted only 43 times since its discovery back in 1976 off Oahu, Hawaii. These sharks are huge and bizzare creatures, capable of growing upwards of 5m in length, with luminescent light organs surrounding the mouth to attract plankton and small fish. So … Continue reading Endangered shark found. Eaten.
It’s 2099, and across south-east Asia, a hundred million people are on the march, looking for food. The fish they once relied on is gone.
Communities are breaking down; economies destroyed. That is what we can expect, says the new WWF report, if the world’s richest coral reef is destroyed. And that, it says, could happen this century.
It’s billed as a worst-case scenario, but the report’s chief author, Professor Ove Hoegh-Guldberg, says it is not as bad as the future we’re currently headed towards. Continue reading World Ocean Conference (Part I): Key coral reefs ‘could disappear’
