Members of the drill crew prepare the casing string for Hole U1456D. Casing is used to stabilize the borehole walls in holes where we plan to core to depths typically >1000 m below seafloor. Casing is important in Hole U1456D because of the unconsolidated sands in the upper part of the section. (Credit: Bill Crawford, IODP JRSO) [Photo ID: exp355_059]
