From the Entire Globe to a Single Volcano
Only 5% of global seafloor charted with ships - we need 125 more years!
Sea Beam detects seafloor features the size of this room
- over depths of several miles….
Notes:
Many new discoveries in recent years with these mapping tools, particularly on seafloor spreading centers or Mid-ocean ridges (MORs)
Account for ~70% of global volcanism
3 cubic kilometers of new crust produced per year
3 cubic kilometers is enough to pave entire U.S. interstate highway system to height of 6 feet!!
