Historic Expeditions    Secrets of the Gulf Expedition


Argus is the name of the Remotely Operated Vehicle (ROV) used to explore the Gulf of Mexico during the Secrets of the Gulf expedition. Unlike many ROVs that are self-propelled, Argus is towed behind a surface vessel (in this case, the Carolyn Chouest). Small thrusters provide some additional maneuverability from side to side or up and down in the water column.

Argus can be equipped with a variety of cameras and sensors according to the needs of the expedition in which it is employed. For the Secrets of the Gulf expedition, Argus carried 5 cameras, a sub-bottom profiler and a multi-beam sonar system. The sub-bottom profiler used sound waves to create a picture of the geological structure beneath the sea floor, while the multi-beam sonar used sound waves to give us detailed information about the contours of the sea floor itself.

Perhaps the most valuable piece of equipment from the sanctuary's perspective was the hi-definition video camera which captured 38 hours of high-quality deepwater habitat footage. This will aid in our habitat characterization efforts in the sanctuary and its surroundings.
