New research provides better look at ocean plate under Central America
Convection in Earth’s mantle is the “engine” driving plate tectonics. Hot material rises to the Earth’s surface from the boundary between the planet’s core and mantle, at a depth of about 3000 kilometers. Cold material then flows downward due to oceanic tectonic plates sinking into the mantle at subduction zones on the Earth’s surface.

Mariana: The Tectonic Neighborhood
This is the latest in a series of dispatches from scientists and education officers aboard the Schmidt Ocean Institute’s R/V Falkor. This November, scientists aboard the research vessel Falkor will aim to shed light on the Mariana Back-arc, which is expected to be teeming with activity and life. Over the course of their 27 day mission at sea they will explore the back-arc spreading center to find new sites of hydrothermal activity and to better understand the physical, chemical, and geological forces that shape biodiversity in these unique ecosystems. Read more posts here, and track the Falkor’s progress here.
