Hydroacoustic studies have shown that near the sea-floor of continental slope significant fluctuations of the redox chemocline depth-location could be observed: up to 29 m (160-131 m) in the north-western Black Sea and up to 14 m (163-149 m) near the Kerch Strait. Corg. sedimentation flux into the benthal of continental slope varies between 17 - 143 g·m-2·year-1. The intensity of organic matter production by autotrophic microbes including methane- and sulfide-oxidizing microorganisms within the chemocline at the periphery of the Black Sea H2S-zone reaches 42-61 g Corg.· m-2 · year-1 which is comparable with the average estimates of biosedimentation. The total abundance of benthic organisms in the redox-zone has been indicated by the range of 1512-13248 ind.·dm-2.
