Offshore operations

Expedition 313 carried three types of coring tools: a hydraulic piston corer (HPC; equivalent to the advanced piston corer [APC]), an extended nose corer (EXN; equivalent to the extended core barrel [XCB]), and a standard rotary corer (ALN; equivalent to the rotary core barrel [RCB]). See Table T1 for a summary of operations. Please see the "Methods" chapter for a description of the coring technology.
