Instrument Platform Details


Tempo-MiniTempo-mini, designed and developed by our French collaborators IFREMER, is a multi-instrument platform for studying deep-sea hydrothermal ecosystems. The oxygen sensor helps scientists detect hypoxia (low-levels of oxygen) and the iron sensor provides a series of high-frequency data to analyze iron and sulphide concentrations in hydrothermal areas. Tempo-mini is powered by an electrical unit and oil-filled junction box, and is even equipped with an anti-biofouling system to deter marine life from residing on the sensors and camera lens.

Tempo-mini's HD video camera is focused on a hot vent benthic community, providing a live view of interactions among tubeworms, scale worms, limpets, sea spiders, snails, vent fish, bacterial growths and other organisms in this unique hydrothermal vent ecosystem.
