Head Egorov V.N., Registration Date 21-02-2008 Organization Kovalevsky Institute of biology of the southern seas, NAS of Ukraine popup.description2 Quantitative evaluations of methane emission to the hydro - and atmosphere from the gas seeps in the region of the Dnieper paleodelta ( north-western part of the Black sea) have been received.The map of methane seeps distribution in the given region of 387.1 km2 has been produced; here 2200 seeps, emitting 16.7.10 6 m3 methane per year under atmospheric pressure, of which only 1,9% of methane reach atmosphere and 98,1% dissolve in the water thickness were identified. With the help of gas - chromatographic measurements it was stated, that the range of methane concentrations in the upper layer of water in the Sevastopol coastal regions makes from 0,54 to 20,36 mkl-l-1. Average meaning of methane concentration in spring is equal to 2,31, in summer - 7,74mkl-l-1. The range of methane concentrations in the surface layer of the bottom sediments made 0,02 - 18,67 mkl-ml-1. Product Description popup.authors popup.nrat_date 2020-04-02 Close
