It's all hydrothermal vent work at a site called TAG. They're like chimneys on the ocean floor that belch superheated water and mineral rich sulphide 'smoke'. They're fragile and really cool. We'll be sampling and sticking all sorts of probes in them ... yike....well the ROV's arms will do the actual work. Anyway, it's an alien landscape 4000m below the surface....If you do a search for 'hydrothermal vents' and jason (that's the ROV) you should find lots of cool pix (some I may have taken myself 8-)
