Currently on MARS

DEIMOS

The DEIMOS system works like the “fish finder” used on many recreational fishing boats, but instead of pointing down from the sea surface, it points up from the seafloor.
3D hydrophone

Directional Hydrophone

The Directional Hydrophone enables determination of the direction from which sounds come.

Ocean Soundscape

Hydrophone records sounds that originate from living organisms, natural processes and human activities.

Legacy MARS Science Experiments

Benthic Rover

The Benthic Rover autonomously transits the seafloor taking measurements of sediment community oxygen consumption, which the lab uses to calculate organic carbon demand.

CTD Sensors

CTD Sensors - Temperature, conductivity and pressure data from SENSORS CTD deployed on MARS.

Deep-Sea Environmental Sample Processor

Deep-Sea Environmental Sample Processor - MBARI's robotic biology lab already filters microbes from surface water and identifies them on its own. To study deep-sea life, this new ESP must be able to do its careful lab work in 90 times the pressure we feel on land.
eye in the sea

Eye in the Sea

Eye in the Sea – This low-light camera sits quietly and looks for shy creatures by the eerie glow of their bioluminescence – a feature shared by 90 percent of deep-sea life. So far, we’ve studied the deep using loud subs with bright lights. Eye in the Sea uses a stealthier approach.

Free Ocean CO2 Enrichment system (FOCE)

The FOCE experiment is designed to study the effects of increased carbon dioxide concentrations in seawater on marine animals. This experiment is of vital importance, since seawater is becoming more acidic as more and more human-generated carbon dioxide dissolves from the atmosphere into the world’s oceans.

Light on MARS Project

Sensors record in situ bioluminescence to study the presence of organisms at night or in the dark ocean without disturbing them.
