A dense array of sensors ( more than 50) were deployed for three consecutive six-month periods from October 2015 to April 2017 within Monterey Canyon. Traditional moorings with instruments strung between floatation packages and anchors (railroad wheels) were deployed. Additionally, instruments were mounted on platforms and deployed on and buried in the seafloor. These instruments monitored conditions in the water column and near the seafloor.
An MBARI based team led by Charlie Paull and Brian Kieft created a “smart boulder”—a motion-sensing instrument that can be placed within the sediment or on the canyon floor. This device, called a benthic event detector (BED), can record its motion as it moves down-canyon, providing detailed data on when an event occurred, how far and fast it moved, and the nature of its motion.
