中国科学院海洋研究所探明中尺度涡引起海温变率关键过程
中尺度涡 海温变率 厘定涡旋
2022/9/22
近日，中国科学院海洋研究所研究员王凡团队在中尺度涡旋引起海表面温度异常的研究中取得进展，通过资料分析和数值模拟厘定涡旋引起海温异常的关键过程为侧向平流，并指明涡旋移动和背景流是决定海温异常结构的关键因素，完善了对中尺度海温变率的认识，且具有很高普适性，对海洋涡旋动力学、中尺度海-气相互作用和海洋数值模拟与预测研究有一定参考意义。
Genesis of structural features of humic acids from the sediments of a high productive coastal zone

Chemical and physical properties of humic acids (HAs) isolated from Mudbanks (locally known as “Chakara”—a
unique phenomenon occurring along the south west coast of India during the southwest monsoon...
Estimation of methanogenesis by quantification of coenzyme F430 in marine sediments
methane hydrate methanogens function-specific compound analysis marine sedimen
2017/4/10
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase
(MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Origin of Earth’s oceans: An assessment of the total amount, history and supply of water
origin of water age of oceans water in Earth planet formation snow line
2017/4/10
The presence of water on Earth has played important roles in shaping the solid regions of the planet as well as in the
origin and evolution of life. This paper addresses three fundamental aspects of ...
In the spring of 1861 Matthew Fontaine Maury, whom many of us know as "The Pathfinder of the Seas" and the first Oceanographer of the U.S. Navy, had something of a change of heart and, perhaps as a re...
A major problem in coastal oceanography is the lack of knowledge of the spatial and temporal scales at which water masses of various origins interact within the coastal zone. While their gross charact...
The fact that we may soon be able to virtually walk (or run) through our data is exciting. I have often felt that support for oceanography would be better if people could see ocean currents, river plu...
Computed Tomography of Macrostructure and Physical Property Variability of Seafloor Sediments
Macrostructure Physical Property Variability

In late autumn 1993, a conference on Satellite Altimetry and the Oceans was held in Toulouse, France. The TOPEX/Poseidon satellite had begun the second year in orbit, and all indications were that the...
STRATAFORM: A Program to Study the Creation and Interpretation of Sedimentary Strata on Continental Margins
Program Sedimentary Strata
2015/8/13
Continental margins are complex regions of the Earth, because they are the interface between terrestrial and marine environments. Many natural processes occurring on land or in the ocean combine to in...
