Zooming closer with the cameras on the ROV, we can see frozen sulphur rivulets covering the rocks. Molten sulphur at high temperature is black while the yellow sulphur indicates a lower temperature when molten. Diffuse vent fluids in the area promote the growth of bacteria, attracting dense populations of shrimp that graze on the food source.
