Mysteries of the Galapagos Seafloor Revealed

Ever wonder what the seafloor of the Galápagos looks like? What goes on below the surface around the magnificent cluster of islands that Darwin’s finches and those wonderful giant tortoises call home? Our partners at the Khaled Bin Sultan Living Oceans Foundation went to find out, and the results have captured our imagination.
Using an innovative high-resolution seafloor habitat mapping technique, researchers from the Living Oceans Foundation (KSLOF) and the National Coral Reef Institute at Nova Southeastern University collected hundreds of underwater videos and over one million depth readings around Baltra, Darwin, Floreana, Isabela, Marchena, Urvina, and Wolf Islands in June 2012 as part of the six-year KSLOF Global Reef Expedition.
Using a method of collecting shallow water surveys called “groundtruthing,” the team covered over 750 square kilometers of seafloor around the Galápagos.…

Literally Looking Through Waves

Did you know NASA has developed breathtaking technology that allows us to literally look through waves? Far from being distorted by the waves, the resulting image is actually more defined and 3D. To get the full scoop, Dr. Sylvia Earle led a Mission Blue envoy to NASA Ames Research Center this past summer. What we learned was nothing short of remarkable: NASA is poised to use this technology to map the shallow reefs of the world in unprecedented detail and give scientists the clearest picture yet of what we are losing where. With this information, we hope that an even stronger case can be made for conservation.
As part of our trip to NASA, Mission Blue’s Brett Garling produced the following video in which you’ll learn all about this amazing new technology — called fluid lensing — and what hope it holds for the world’s oceans.…

New Seafloor Map from Scripps uses Google Earth to Reveal Mysteries of the Deep

By Courtney Mattison
Sylvia Earle often says, “We know more about space than we do about our ocean.” That surprising fact may soon change thanks to a new map produced using satellite data of variations in Earth’s gravitational field to reveal features of the seafloor that were previously undiscovered. By tapping into data streams from the Jason-1 and CryoSat-2 satellites, researchers at Scripps Institution of Oceanography at UC San Diego and their colleagues have made a breakthrough in seafloor mapping that “is like the difference between ordinary and high-definition television.”[i]

The data collected for the new seafloor map will inform the upcoming version of the global ocean seafloor in Google Earth and Maps and fill in large voids between shipboard depth profiles that have provided lower resolution seafloor mapping data in the past.…
