Based on recent technological developments, it is now possible to continuously monitor hydrothermal vents ecosystems using video cameras connected to seafloor installations, called observatories. The TEMPO ecological module, designed and developed by IFREMER teams, can monitor the daily activities of animal communities. It is fitted with a video camera, four spotlights on articulated arms, a temperature probe, an oxygen probe and a chemical analyser to determine the iron concentrations in the environment in real time.
Two versions of the TEMPO module are currently deployed on deep-sea observatories: EMSO-Azores on the Mid-Atlantic Ridge and NEPTUNE Canada on the Juan de Fuca Ridge in the Pacific Ocean. Videos sequences from the Pacific can been screened using the ONC Seatube channel !
