Robots help to map England’s only deep-water Marine Conservation Zone
Dr Veerle Huvenne from the NOC, who led the 5-week expedition, said: “Our robot vehicles imaged rich communities of cold-water corals, clams, deep-sea oysters and their associated fauna, including a broad range of fish species. We also captured amazing footage of Blue Sharks and Swordfish when the Isis marine robot was travelling to and from the seabed. ”

What does the Hubble Telescope and a Whale Shark have in common?
The Groth algorithm is a pattern-matching algorithm invented by Edward J. Groth, a Princeton physics professor, in 1986 that that could compare and identify complex star patterns by triangulating all of the possible star triplets in a given image.
This was added to Hubbles STSDAS software package to assist in mapping the some 10,000 galaxies of the famous Hubble Ultra Deep Field image.
the following excerpt from: http://www.techbriefs.com/component/content/article/23-ntb/features/feature-articles/21708-hubble-spinoffs-space-age-technology-for-the-masses?start=1
“In 2002, scuba diver Jason Holmberg had a rare encounter with a whale shark, an endangered species characterized by its distinctive markings – a unique pattern of white spots on its skin as distinctive as a human’s fingerprints. Tracking the fish by comparing photos and matching spots was a tedious and imprecise science, so Holmberg turned to an astrophysicist friend of his, Dr. Zaven Arzoumanian. Through Arzoumanian’s work with the Goddard Space Flight Center, they came across the Groth algorithm and realized it could be adapted to their purpose. They modified the algorithm to compensate for the graphical differences between the size and shape of a whale shark’s spots and stars in the sky, and made several other enhancements.
Since then, Holmberg has assembled a whale shark database called the ECOCEAN Whale Shark Photo-identification Library, to which anyone can contribute photos.“
