  description: A high-resolution analysis of Hole 1017E revealed that total organic carbon (TOC) concentrations (24.8 ± 2.9 mg/g) and d13C of TOC (-21.3 ± 0.2 per mil) in Holocene sections are higher than those in glacial sediments (14.2 ± 4.8 mg/g and -22.1 per mil ± 0.1 per mil, respectively). The 306- to 280-cm section has high total sulfur concentrations, which may correspond to anoxia Event 1 (1 of the warm interstadials of GISP2) in the Santa Barbara Basin.
