A team of marine scientists and technicians recently located and retrieved more than $0.5 million in oceanographic instruments that had been considered lost on the sea floor. The retrievals from depths up to 4.8 km were made with the help of newly developed grappling hooks designed to hold on to the wires of instrument moorings (Figure 1).

The Scripps Institution of Oceanography, part of the University of California, San Diego, announced that six separate moorings of oceanographic instruments were recovered in a month-long operation last summer on the Scripps research vessel Melville. The operation took place in the equatorial Pacific Ocean, southeast of Hawaii.
