In May this year scientists studying the West Mata submarine volcano in the south-west Pacific as part of the NOAA Vents Program captured the deepest undersea eruption yet filmed on video (as your favourite volcano bloggers reported at the time). The findings and images have just been presented at the AGU Fall Meeting in San Francisco: the NOAA has two videos and a wealth of still imagery. West Mata is at the northern end of the Tonga Arc, and rises to 1174 metres below sea level. The water around the vents is highly acidic: microbial life is present, but shrimps are the only form of animal life to thrive around the vents.
