As part of the UNOLS Academic Research Fleet, LDEO’s R/V Marcus G. Langseth has supported seismic surveys since 2008, but this is the first 3D survey since 2016, and the first-ever 4D (time-lapse) survey! 🚢 Learn more: instagram.com/p/DWcOauXjLvK/

What does “seismic coverage” mean? Think of the R/V Marcus G. Langseth mapping the seafloor like mowing a lawn: one pass isn't enough. We run line after line in a controlled pattern to build consistent coverage across the area. 🚢 Learn more: instagram.com/p/DWaanaSDN_Q/

On Field Geology Barbados trip, students ventured into Cole's Cave. Barbados is formed from uplift of accretionary sediments with coral reef building on top of them. Caves form when groundwater reacts with carbonate fossil coral reef rocks, becomes acidic, and dissolves calcite.
