“…Currently, the mechanisms for the observed link between sulphur and nitrogen cycling in soils is still not understood. However it is known that S-containing amino acids such as methionine, 10 cystine and cysteine are all potential precursors of COS and CS2 (Bremner & Steele, 1978;Minami & Fukushi, 1981a;Minami & Fukushi, 1981b). Soils exposed to higher nutrient inputs may thus contain soil organic matter with relatively more Ncontaining precursors available for either biotic or abiotic degradation.…”

Abstract. Soils both emit and consume the trace gas carbonyl sulphide (COS) leading to a soil-air COS exchange rate that is the net result of two opposing fluxes. Partitioning these two gross fluxes and understanding their drivers are necessary to 10 estimate the contribution of soils to the current and future atmospheric budget of COS.Previous efforts to disentangle the gross COS fluxes from soils have used flux measurements on air-dried soils as a proxy for the COS emission rates of moist soils. However, this method implicitly assumes that COS uptake becomes negligible and COS emission remains steady while soils are drying. We tested this assumption by estimating simultaneously the soil COS sources and sinks and their temperature sensitivity (Q10) from soil-air COS flux measurements on fresh soils at different COS 15 concentrations and two soil temperatures. Measurements were performed on 27 European soils from different biomes and land use types in order to obtain a large range of physical-chemical properties and identify the drivers of COS consumption and production rates.We found that COS production rates from moist and air-dried soils were not significantly different for a given soil and that the COS production rates had Q10 values (3.96 ± 3.94) that were larger and more variable than the Q10 for COS consumption 20(1.17 ± 0.27). COS production generally contributed less to the net flux that was dominated by gross COS consumption but this contribution of COS production increased rapidly at higher temperature, lower soil moisture and lower COS concentrations. Consequently, measurements at higher COS concentrations (viz. 1000 ppt) always increased the robustness of COS consumption estimates. Across the range of biomes and land use types, COS production rates co-varied with total soil nitrogen (r = 0.68, P < 0.05) and the first-order COS uptake rate co-varied most with microbial N content (r = 0.64, P < 0.05) 25providing new insights on how to upscale the contribution of soils to the global COS atmospheric budget.Atmos.

“…Bacteria are known to produce DMS only during decomposition of organic matter or in the presence of organosulfur substrates (Bremner and Steele 1978;Kadota and Ishida 1972). DMS is produced during the anaerobic decomposition of algal mat material (Zinder et al 1977).…”

Dimethylsulfide in the water column and the sediment porewaters of the Peru upwelling area1

The concentration of dimethylsulfide (DMS) and supporting parameters were determined on longshore and cross-shelf traverses in the Peru upwelling area. Vertical DMS profiles were measured at several stations in the marine water column and in the sedimentary porewaters. The distribution of DMS in surface waters is related to the patchiness of the upwelling process and of the resulting phytoplankton biomass. Substantial concentrations of DMS were found in the sedimentary porewaters, with a sharp maximum a few centimeters below the sediment-water interface. The source of this DMS is most likely the decomposition of algal material which settles to the bottom beneath the upwelling areas. The rates of DMS production in the water column and its flux into the atmosphere across the air-sea interface are only a small fraction of the rate of sulfate assimilation by the plankton community. The concentrations of DMS in the surface waters of the Peru shelf are similar to those found in other coastal areas; the fluxes of reduced sulfur gases to the atmosphere from this upwelling region do not require special consideration in the global atmospheric sulfur budget.
