LBL Beacon Recovery Release
Middle School Student Anja Diercks learns about acoustic release operation to recover a Long Base Line (LBL) acoustic beacon after a successful AUV dive. These LBL beacons are necessary in aiding the Inertial Navigation System of the AUV while on survey on the ocean floor, sometimes at depths of 1600 m or more.
LBL Beacon Recovery
Middle School Student Anja Diercks helps recover the acoustic LBL (Long Base Line) beacon she had released from the ocean floor using an acoustic telemetry system minutes before. The Gulf of Mexico had a surprise for her too.
Fiberoptic Multicorer
Watch this successful collection of deep sea sediment cores during 7+ foot waves on a recent research cruise in the Gulf of Mexico. The Science team from National Institute for Undersea Science and Technology and Mississippi Mineral Resources Institute deployed a deep sea multicoring device in 1200 meters of water depth, attached to a fiberoptic winch cable. On the coring rig, they mounted several cameras and light sources. This spectacular mission was accomplished aboard the RV Pelican, during a recent research conducted for ECOGIG.
