Abstract

Based on long-term data on the spatial distribution and fluxes of streaming (bubbling) methane in the Black Sea, the study considers various types of streaming gas emissions contributing to the methane content in the anoxic zone of the Black Sea. The estimate for the annual influx of methane gas emissions to the methane budget in the Black Sea was 1.2 × 10⁹ m³ or 0.9 Tg, which is significantly less than the estimates obtained by biogeochemical methods (2.30–5.65 Tg yr^–1).

甲烷涌入黑海盆地缺氧水域

摘要

根据有关黑海中甲烷流（冒泡）的空间分布和通量的长期数据，该研究考虑了各种类型的甲烷流排放气体，这些排放气体有助于黑海缺氧地区的甲烷含量。黑海甲烷气体排放量每年流入甲烷预算的估计数为1.2×10 ⁹ m ³或0.9 Tg，大大低于通过生物地球化学方法获得的估计数（2.30-5.65 Tg yr ^–1）。
