</i></b>BREWSTER, MA The Cape Cod Museum of Natural History in Brewster
presents Dr. Susan Humphris Senior Scientist at the Woods Hole
Oceanographic Institution in the Geology and Geophysics Department
<b>Thursday, July 30, 2015 at 1pm.<br><br>
</b>Just over 35 years ago, scientists exploring the mid-ocean ridge
system made the spectacular discovery of black smokers chimney-like
structures made of metal sulfide minerals that vigorously discharge hot,
particulate-laden fluids into the deep ocean. The ultimate source of the
fluid venting from these smokers is seawater, but the chemistry of the
hydrothermal fluid is distinctly different. The vent fluids are not only
far hotter than surrounding seawater, they are also more acidic and
enriched with metals, and have much higher concentrations of dissolved
gases, such as hydrogen, methane, and hydrogen sulfide. The metals
transported by the fluids frequently form mineral deposits at the
seafloor, and the dissolved gases support a prolific biological community
that derives its energy from chemical reactions rather than sunlight.
Through a series of dives to the seafloor using different types of deep
submergence vehicles, we will explore and compare hot springs and mineral
deposits in the Atlantic, Pacific and Indian Oceans, and learn about the
processes that transform seawater into the remarkable fluids that
discharge from hydrothermal vents.<br><br>
In addition to being a research scientist, Dr. Humphris has also built a
successful career in science administration and communication. As a
senior scientist she has chaired the Marine Geology and Geophysics
department at WHOI, served as vice president of Marine Facilities and
Operations, and overseen the recent 50th anniversary overhaul and upgrade
of the submersible Alvin.<br><br>
The presentation will be held at the Museum Thursday, July 30th at
1pm.<br><br>
