Table T1. Expedition 311 operations summary.
Notes: LWD/MWD = logging-while-drilling/measurement-while-drilling operations. BSR = bottom-simulating reflector. APC = advanced piston corer, XCB = extended core barrel. APCT = APC Temperature tool, DVTPP = Davis-Villinger Temperature-Pressure Probe, PCS = Pressure Core Sampler. TD = total depth. Triple combo = triple combination tool string, FMS = Formation MicroScanner. VSP = vertical seismic profile; WST-3 = three-component Water Sampling Temperature tool. Assumes 24 h required for boarding of scientists in Astoria, thus limiting Balboa port call to 4.0 days maximum. Assumes drill string round trip with LWD and MWD tools (memory download and battery change) after Sites CAS-02C and CAS-06A. Approval to drill Site CAS-06A is pending. If denied, then Site CAS-06B will be drilled.
