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...
When glacial ice sheets melt, something counterintuitive happens to sea levels. Logic might suggest that nearby levels would rise, but instead they fall.
An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes...
New research reveals significant changes in the circulation of the North Pacific Ocean and their impact on the initial migration of humans from Asia to North America.The U.S. National Science Fou...
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the oceans. Now researchers from the University of Connecticut and other institu...
The most common organism in the oceans, and possibly on the entire planet, is a family of single-celled marine bacteria called SAR11. These drifting organisms look like tiny jelly beans and have evolv...
Scientists have confirmed that viruses can kill marine algae called diatoms, but diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae.Diatoms ar...
近日,中国地质大学地球科学学院和生物地质与环境地质国家重点实验室宋海军教授团队在自然子刊《Nature Communications》上发表题为“The onset of widespread marine red beds and the evolution of ferruginous oceans”的学术论文,阐述了地质历史时期海相红层的时空分布规律和形成机制,揭示了38亿年以来海洋铁含量的...
Alaska’s history is deeply connected with the sea. From the Alaska Native peoples who knew Alaskan waters best and relied on them for food and transportation, to explorers like Captain James Cook seek...
Commercial fishermen may be able to catch more of the profitable fish they want with marine reserves than without them, according to a study in the journal PNAS led by the University of California, Da...
