(Table 1) Turbidity, temperature, and salinity in the hydrothermal plume and background waters above the northern part of the Mohn's Ridge at Station AMK36-3573-5

In July 1995 geological and biological studies in the axial zone of the northern part of the Mohn's Ridge (72°20'N) were carried out during Cruise 36 of R/V Akademik Mstislav Keldysh. Slopes of the neovolcanic zone, as well as a caldera on its crest were investigated with use of deep-sea manned submersibles Mir, geological and biological samples were also collected. Use of the Rosette sounding complex provided recognition of several major hydrothermal plumes. Bottom sediments of the marginal depression are enriched in metals characteristic for hydrothermal metalliferous sediments. Thus, a new unknown hydrothermal field was found.1995年7月，依托“姆斯季斯拉夫·凯尔迪什院士号”（R/V Akademik Mstislav Keldysh）第36航次，科研团队在莫恩海岭（Mohn's Ridge）北段轴带（北纬72°20′）开展了地质与生物学综合考察。本次研究借助“和平号”（Mir）深海载人潜水器，对该区域新火山带的斜坡及其顶部的破火山口（caldera）进行了详细勘察，并采集了地质与生物样本。通过罗塞塔综合探测系统（Rosette sounding complex）的作业，团队识别出多处主要热液羽流（hydrothermal plumes）。边缘凹陷区的海底沉积物中，富集了热液含金属沉积物（hydrothermal metalliferous sediments）典型的金属组分。据此，本次考察发现了一处此前未被记录的全新热液场。
