[SEMCO] Free public event at Woods Hole Oceanographic Institution

[Joanne Tromp]

*DEEP OCEAN EXPLORATION: TRENCHES*

On Saturday, August 24, from 9:30 a.m. -- 2 p.m., the Woods Hole 
Oceanographic Institution hosts a public event featuring*science talks* 
in Redfield Auditorium about the deepest parts of the sea -- the 
trenches --and *tours* on the WHOI dock of the /DEEPSEA CHALLENGER/ and 
/Nereus/ -- the only vehicles currently able to reach the ocean's 
greatest depths. The dock opens at 9:30 a.m. for vehicle tours. The 
presentations will be held at 10:30 a.m. and 12:30 p.m.

*About the presentations*: Learn about scientific exploration in the 
deepest parts of the sea -- the trenches. Extending from depths of 6,500 
meters (~21,000 ft) to 11,000 meters (~36,000 ft), the trenches are a 
vast unknown part of our planet. WHOI scientists and engineers are 
working together to probe these depths using vehicles capable of 
withstanding pressures of 16,000 pounds per square inch. Hear about the 
dynamism of the trenches -- earthquakes, volcanoes, and subducting 
tectonic plates from *WHOI geologist Dan Lizarralde*, the life forms 
found in the trenches from *WHOI biologist Tim Shank*, and the 
challenges engineers face when building a vehicle to reach these depths 
from *WHOI engineer Andy Bowen*.

The one-hour program will run at 10:30 am and 12:30 pm.
