2The oceans represent gt70 of Earth's surface
area, yet we have explored in detail less than a
few percent of the deep seafloor
3(No Transcript)
4The oceans have played a major role in human
history, and the global economy
5We know less about the deep seafloor than we do
about the surface of other planets in our solar
system, like Mars
