| Abstract: | In order to address the need for high-quality sediment oxygen demand (SOD) measurements, diver deployed benthic flux chambers equipped with sondes were used to assess SOD (aerobic uptake) and the sediment-water fluxes of constituents in regions of Long Island Sound (LIS) characterized by periods of summer hypoxia/anoxia. Procedures were developed for deploying chambers from small vessels, and our sampling techniques employed equipment custom designed at our laboratory. SOD measurements in western LIS during both winter (850 µmol O2 m-2 h-1) and summer hypoxic conditions (870 µmol O2 m-2 h-1) showed good agreement over small spatial scales. Although the benthic oxygen utilization constant (k) was 6-7 times higher in the summer, low ambient DO (hypoxia) in western LIS bottom waters at this time accounted for reduced SOD rates. |
