Two samples were collected from the Santa Monica Mounds in May 2013 from push core 51 (PC51) on dive DR-461 from a white mat at site 3 (33° 47.3301'N, 118° 40.0979'W depth 863 m). Upon recovery shipboard, the push core was separated into two samples that were used for metagenomic sequencing. Sample 7086 was created from sediment in the 6-9 cm horizon of the push core. The remaining sediment (0-6 cm 9-15 cm) was combined and used as sample PC51mix.
