“…Most low-marsh substrates are rich in H2S and organic matter, have high potential for oxygen demand, have low pH but variable Eh, and contain abundant aerobic and anaerobic bacteria (Tables 5 and 6; Kurz and Wagner, 1957;Stevenson and Emery, 1958;Pomeroy, 1959;Oppenheimer, 1960;Teal and Kanwisher, 1961;Bradshaw, 1968;Berner, 1969;Friedman and Gavish, 1970;Wiedemann, 1972b;Day et aI., 1973). The sediments therefore tend to be highly reactive, Reactivity of marsh sediments perhaps is most strikingly illustrated in areas that have been manipulated.…”

Rates of bacterial sulfate reduction are calculated from the accumulation of reduced sulfur compounds in coastal sediments. The method is found to underestimate the in situ metabolism 10-fold because it neglects diffusional losses of produced sulfide. In relation to this result, the quantitative connection between the pyrite, HClextractable iron, and organic carbon contents of the sediments and the intensity of sulfate reduction are disussed. A comparison is made between colony counts of sulfate-reducing bacteria and the rate of sulfate reduction in coastal sediments. The number of bacteria is roughly proportional to their measured rate of metabolism both when different sediment types and different depths are compared. The colony counts, however, seem to underestimate the true numbers of sulfate reducers by 1000-fold or more.

“…In fact, Waksman and Hotchkiss (1937) suggested that the rate of oxidation of organic matter in bottom material be used as a measure of the availability of its organic-matter content. Oppenheimer (1960) reviewed the relationship between decomposition of sedimentary organic matter and sediment particle size. Since finer sediment contained relatively more refractory organic matter, Pinck (1962) suggested that bacterial enzymes are too large to penetrate the sheetlike structures of clay minerals in which organic matter is absorbed.…”

Oxygen consumption by the seabed in Puget Sound was measured in situ in bell jars pushed into the bottom while monitored by television.Eleven stations were visited irregularly between January and August 1967. Depths ranged from 11 to 180 m, and sediment varied from coarse sand to mud. Observed short-term rates were between 4 and 40 ml 0, m-a hr-l and were unrelated to depth (pressure), mean grain size, fine fraction of the sediment, organic matter or organic nitrogen in the upper 0.5 cm, or the biomass of macrofauna.Temperature accounted for only about 30% of the total variation in rates. We suggest that the seasonal changes of rates, and possibly the differences between stations, are caused primarily by changes of activity of small organisms as governed by the rate of supply of organic matter from the plankton.Estimates of annual rates of oxidation of organic matter on the seabed correspond to 17 and 25% of the phytoplankton production ("C uptake) near the stations in northern and southern Puget Sound, respectively.
