Notes: * = temperature logger mounted in PVC holder inside OsmoSampler assembly. System components are listed top to bottom for each hole. Instruments in Holes U1362A and U1362B were deployed during Expedition 327. Instruments in Hole 1026B were deployed with Alvin in summer 2008. Instruments in Hole U1301A were deployed with Alvin in summer 2009. Depths reported are for base of each component: mbsf = meters below seafloor, msb = meters subbasement. Total length is from top of OsmoSampler string to base of sinker bar. Depth of bullnose tip is at end of CORK casing. All Expedition 327 OsmoSampler systems were deployed above this depth inside perforated and coated casing and collars.
