תמציתה:
n a first for the U.S. Navy, an underwater glider was launched with the aid of Navy divers from the Dry Deck Shelter aboard USS Buffalo (SSN 715) November 14.
The glider is a uniquely mobile network component capable of moving to specific locations and depths and gathering various information, which is transmitted on a predetermined interval when it surfaces to computers via a built-in satellite phone.
"Our interest in the submarine force has been to use these to characterize the ocean," explained Lt. Cmdr. Patrick Cross, Pacific Submarine Force oceanographer.
"They're equipped with sensors that can give us [readings on] salinity and temperature versus depth, and from that we can get sound speeds (the localized rate at which sound from a source travels through water). We can feed that data into our MODAS (Modular Ocean Data Assimilation System), run by the Naval Oceanographic Office, and that provides a picture that we provide to our submarines," said Cross. |
