Research Expedition Photo Gallery
Our research projects start when we sail on research cruises, often 20 to 60 days at sea, to core sediment from the seafloor. Deeper layers of sediment were deposited earlier than the shallower layers, so coring deep below the seafloor is like looking back through time. Many land and ocean processes affect the type and geochemistry of marine sediment that accumulates on the seafloor. By analyzing different layers in the core, we can determine how these processes have changed over time.
Check out the gallery of photos from research expeditions I’ve sailed on for an idea of what it is like coring marine sediment and doing science at sea.
