Monterey Accelerated Research System (MARS) • MBARI (original) (raw)

The MARS science node consists of two pieces: the massive orange “trawl-resistant frame” and the electronics package, which fits inside this frame.

The trawl-resistant frame consists of a truncated pyramid made of steel plates that is 3.7 by 4.6 meters (12 by 15 feet) wide at the base and 1.2 meters (4 feet) tall. This frame protects the node’s electronic components from boat anchors or commercial fishing gear. Its smooth corners and sloping sides are designed to prevent such gear from snagging. Doors on each side of the frame can be opened, allowing remotely operated vehicles to plug or unplug experiments.
