In Revellata Bay (Gulf of Calvi, Corsica, France), the sparid fish Sarpa salpa L. is the main macro-consumer of Posidonia oceanica (L.) DELILE leaf. Stomach contents were analysed and C-13/C-12 isotopic ratios were measured in fish muscle and potential food sources (algae, P. oceanica leaf and its epiphytes) to determine their relative contribution to the fish diet. S. salpa has an age-related mixed diet: juveniles are plankton feeders, young, sub-adults and adults are herbivorous, and, the older the individuals, the higher the relative contribution of P. oceanica to the diet. Our results and former studies of carbon stocks and fluxes in the P. oceanica bed of Revellata Bay have enabled an estimation of the general impact of S. salpa grazing on infralittoral communities: the studied species consumes 24 g C.m-2.a(-1) from P. oceanica leaf, 4.8 from epiphytes and 13 from epilithic algae. The fish net production and biomass turnover in that zone have been estimated to be 1.2 g C.m(-2).a(-1) and 1.5 a(-1), respectively. [less ▲]

A new, completely automated gas chromatography technique has been developed to separate the different gaseous compounds produced during underground coal gasification for their C-13/C-12 and D/H isotope ratio measurements, ?he technique was designed for separation and collection of Hz, CO, CO2, H2O, H2S, CH4, and heavier hydrocarbons. These gaseous compounds are perfectly separated by the gas-phase chromatograph and quantitatively sent to seven combustion and collection lines. H-2, CO, CH4, and heavier hydrocarbons are quantitatively oxidized to CO2 and/or H2O. The isotopic analyses are performed by the sealed-tube method, The zinc method is used for reduction of both water and H2S to hydrogen for D/H analysis, Including all preparation steps, the reproducibility of isotope abundance values, for a quantity higher than or equal to 0.1 mt of individual components in a mixture (5 mt of gases being initially injected in the gas chromatograph), is +/-0.1 parts per thousand for delta(13)C(PDB) and +/-6 parts per thousand for delta(13)C(PDB) and +/-6 parts per thousand for delta(SMOW).
