    Low organic carbon accumulation rates in Black Sea sediments

    THE Black Sea, the world's largest anoxic marine basin, is frequently used as a modern analogue for the formation of organic-rich sediments and carbonaceous rocks1–3, on the widely held assumption that anoxic con...

    Accelerator Radiocarbon Measurements of Artistic Artifacts

    The use of a particle accelerator to measure the 14C content of carbon-containing materials is briefly described. The application of the method to the determination of the age of some artistic artifacts is discus...

    Stable isotope evidence for chemosynthesis in an abyssal seep community

    Communities of abundant organisms, similar to those which surround the hydrothermal vents of the East Pacific Rise (EPR), occur in 3,266 m of water in the Gulf of Mexico. They were discovered with the Alvin at 26...
