From: Spatial scales of bacterial community diversity at cold seeps (Eastern Mediterranean Sea)
Plots of porewater concentration profiles at methane-seeping, reduced sites (a–c; Pock_seep_1) and at nearby non-seep sites from the Pockmark region (d–f; Pock_non-seep_1). (a, d) Depth profiles of total sulfide (closed circles) and sulfate concentrations (open circles); (b, e) DIC concentration (open circles) and alkalinity (closed circles); (c, f) in situ oxygen concentration determined with microsensors, the insert in panel (c) shows the same profile at higher depth resolution. Further detailed geochemistry plots of all regions can be found in the Supplementary Figures S1–S5.
