Abstract

Sediments were collected in Fall 2019 across three transects in the Santa Barbara Basin using the ROV Jason during R/V Atlantis cruise AT42-19. Microbial activity in the sediments was determined by measuring sulfate reduction rates.

Cite Dataset

Sediments were collected with push cores (6 cm inner diameter) along three depth transects across the Santa Barbara Basin using the ROV Jason. 

Sulfate reduction rates were determined by injecting carrier-free 35S-Sulfate into intact whole round cores (2.8 cm inner diameter) according to Jørgensen (1978) and incubated for 1 day. Sediment samples were then analyzed according to the cold-chromium distillation (Kallmeyer et al., 2004).
