This graph shows the optical backscatter data from the second tow-yo above a spreading center. Reds and oranges show where the water was cloudier, while blues indicate mostly clear water. A hydrothermal plume could increase the amount of particular matter at these depths making the water cloudy, but so could many other things... like earthquakes, perhaps?
