海底冷泉（Cold Seeps）是一种来自海底沉积界面以下，以水、甲烷或其他碳氢化合物为主要组分的低温流体，是海洋物质和元素循环的重要途径。冷泉逸出的甲烷90%以上由硫酸盐还原和甲烷缺氧氧化（Anaerobic Oxidation of Methane, AOM）作用消耗。一般认为，SO42-是AOM的主要电子受体。但有研究提出，锰（Mn）有可能参与了AOM，并为化能微生物提供高于SO42-的能量...

Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron
(Fe) to Fe-depleted surface oceans.
Determination of Henry’s law constant of halocarbons in seawater and analysis of sea-to-air flux of iodoethane (C2H5I) in the Indian and Southern oceans based on partial pressure measurements
solubility equilibrator volatile organic compounds
2017/4/12
The sea-to-air flux of C2H5I (iodoethane) in the Indian Ocean and the Southern Ocean was estimated from the Henry’s
law constant (KH) and the measured partial pressures of C2H5I in surface seawater a...
