Women describe life at sea.
These mid-ocean ridges are the sites of hydrothermal vents and the unique ecosystems that the vents support. She is also a geographer who specializes in the software oceanographers of all disciplines use to map and analyze the seafloor. Hydrothermal vents are created when seawater percolates down through the cracks in the ocean crust, is heated by magma, then rises back though the cracks to the surface. Therefore fissures provide important clues to the nature of volcanic eruptions and to the birth and death of hydrothermal vents. She is especially interested in the origin of these fissures.
