Возможные причины эмиссии метана на шельфе морей Восточной Арктики
https://doi.org/10.15356/2076-6734-2014-2-69-81
Аннотация
Анализируются данные различных измерений (морских экспедиционных, стационарных на станции Тикси, спутниковых) концентраций метана в воде и в нижней атмосфере на шельфе морей Восточной Арктики. Рассматриваются возможные причины повышенных по сравнению со среднеширотными значениями концентраций метана, установленных на некоторых участках шельфа этих морей. Сравниваются две альтернативные гипотезы этого: современные изменения субаквальной мерзлоты и геологические причины (тектоника, наличие разломов и русел палеорек на рассматриваемой территории). Показано, что концентрации метана в морской воде зависят от расстояния до ближайшего разлома или палеорусла, где отсутствуют мёрзлые донные отложения и имеются пути для выхода метана из глубоких гидратосодержащих слоёв. Таким образом, на отдельных участках шельфа повышенная эмиссия метана не связана с современным изменением климата. Выполненные ранее модельные расчёты показали, что на шельфе не происходит интенсивного образования сквозных таликов и иных процессов, увеличивающих газовую проницаемость донных отложений. Эти результаты опровергают гипотезу о возможности в обозримом будущем «метановой катастрофы» на шельфе морей Восточной Арктики.
