Follow along on IODP Expedition 385 “Guaymas Basin Tectonics and Deep Biosphere” with the cruise blog of Andreas Teske, co-chief scientist and professor in the Department of Marine Sciences at the University of North Carolina-Chapel Hill. This expedition will explore the most famous ocean spreading center in the Gulf of California, Guaymas Basin, by drilling a Northwest-to-Southeast transect across its flanking regions and axial valley.  Look for expedition updates and images from the drill ship, the JOIDES Resolution, and for background on this expedition, deep earth science, hydrothermal vents, seafloor spreading in action, and subsurface microbiology and geochemistry. Take this opportunity to follow an exciting expedition probing the inner workings of an active seafloor spreading center!
