Polychaete Annelid Biomass Size Spectra: The Effects of Hypoxia Stress

Figure 2

Near-bottom oxygen concentrations at each sampling site (A, B, C, and AB5 in Figure 1) from April 2004 to August 2012, with the horizontal line indicating the 2 mg/L hypoxia threshold. Concentrations below 2 mg/L were considered hypoxic, whereas those below 1 mg/L were categorized as “severe hypoxia.” “Katrina” was a major hurricane that passed through the area several months after the 2005 sampling.
