Speaker to discuss undersea hydrothermal events
Margaret Kingston Tivey, associate scientist in marine chemistry and geochemistry at the Woods Hole Oceanographic Institution, will speak on “The Interplay of Geology, Physics, Chemistry, and Biology in Seafloor Hydrothermal Vent Systems” on April 15.
Margaret Kingston Tivey, associate scientist in marine chemistry and geochemistry at the Woods Hole Oceanographic Institution, will speak on “The Interplay of Geology, Physics, Chemistry, and Biology in Seafloor Hydrothermal Vent Systems” on Thursday, April 15 at 7 p.m. in 106 Thompson Hall at the University of Massachusetts Amherst.
Scientists have discovered that seafloor hydrothermal vents located along mid-ocean ridges at depths of 1,500 to 3,600 meters are dynamic hydrologic systems that release fluids ranging in temperature from near ambient to 350 degrees Celsius. The mixing of vent fluids and seawater result in the formation of massive sulfide deposits at the seafloor, including spectacular “black smoker chimneys.” Tivey will discuss how these hydrothermal systems play key roles in global heat budgets and geochemical balances.
The seminar is sponsored by the Five College Coastal and Marine Sciences Program and is open to the public.
