The biosphere is usually
thought of as plants and animals near Earth's surface, but Earth's habitable
zone extends to depths of hundreds or thousands of meters. The organisms
that live in this environment may collectively have a mass equivalent
to that of all of Earth's surface dwellers and may provide keys to solving
major environmental, agricultural, and industrial problems. Oregon State
University's Suburface Biosphere Initiatve unites faculty and students
from five different colleges who share interests in this underground world.
The last day of funding for the Subsurface Biosphere Initiative was June 30, 2012, but this Website will continue to be offered as a resource on the topic.
