The Benthic Rover II robot developed by Monterey Bay Aquarium Research Institute researchers has spent seven years collecting deep-sea data 140 miles off California's coast.
The battery-powered vehicle operates at a depth of 13,123 feet, crawling the seabed on treads, and measuring phytoplankton and plant debris concentrations, water temperature and oxygen, and the oxygen consumption/carbon dioxide output of mud-dwelling organisms.
Since the rover cannot transmit directly to shore, a Wave Glider autonomous surface vehicle travels to its point of operations, picking up and retransmitting its acoustic pulses to shore via satellite.
The rover operates in one-year cycles, and at their conclusion it is hauled back up to have its batteries changed, its data downloaded, and any required maintenance.
