SRP373234 PRJNA833464 Temporal Succession Associated with Marine Cable Bacteria (Incubation Experiment) Surficial sediment obtained from mesohaline zone of Chesapeake Bay were homogenized and incubated in sediment core liners for 64 days in aerated aquaria. Cable bacteria were allowed to grow unimpeded in a subset of cores. Downward growth of cable bacteria was inhibited by a barrier filter embedded at 0.5 cm in a subset of cores. Sediment cores were destructively sampled and sectioned at 0.5 cm depth increments at 6 times points over the approximately 2 months.
