Figure 1. This tube core measures 8 centimeters (about 3.1 inches) in diameter and collected from a Thioploca bacterial mat in the Peru-Chile oxygen minimum zone. The mat, about 1 cm thick (or 0.4 inches), consists of many individual filaments of giant bacteria. Each filament extends into the sediment and the water, sources of sulfide and nitrate, respectively.
