  • Woods Hole Oceanographic Institution
  • Dept. of Geology and Geophysics

2
The oceans represent gt70 of Earth's surface
area, yet we have explored in detail less than a
few percent of the deep seafloor

4
The oceans have played a major role in human
history, and the global economy
5
We know less about the deep seafloor than we do
about the surface of other planets in our solar
system, like Mars
