Although many marine(海洋的) scientists focus on animals in the ocean others seek to gain a better understanding of the ocean’s chemical and physical components (组成部分). Scientists are learning a great deal about the natural and human-caused processes that shape the ocean and its many life...
for understanding the processes that shape the surface of volcanic arcs; the arid climate and well-constrained geochronology of volcanic deposits provide a geomorphic archive going back 11 Myrs, and the wealth of available geophysical imaging data provides a high-resolution glimpse into the subsurface...
Beachesare wave-deposited accumulations of sediment located at the shoreline. They require a base to reside on, usually the bedrock geology, waves to shape them, sediment to form them, and most are also affected by tides. The beach extends from wave base where waves begin to feel bottom and...
Many major puzzles in Solar Physics have not yet been answered and are of wide importance for astrophysics in general, such as: How is the magnetic field generated? How is the corona heated? How do solar flares occur? What is the effect of solar variations on the Earth's climate? How is...
An object-oriented approach to simulating infiltration and overland flow, retains the natural shape of hydrologic response units (combinations of soil type and land use) by representing each of these "homogeneous' units as an object. Thi... Wolfe,M.,L.,... 被引量: 12发表: 1991年 ...
phytoplankton patterns. Our study contributes to the understanding of natural and anthropogenic factors that drive seasonal successional processes of phytoplankton in the Yangtze River. These findings have important implications for environmental management as well as towards the ecological restoration of large...
Earth in the form of martian meteorites. So far, the only available martian samples that appear to have recorded the early conditions and the evolution of the planet until the present time are Northwest Africa (NWA) 7034 and its paired stones. They are the most diverse martian meteorites in ...

(Bahn et al. 2020, unpublished information). However, the influence between plant and microbes is bi-directional, where plants can shape the soil community and its drought response63and in turn the soil microbes can have important consequences for the plant diversity, community composition and ...
Dy/Dy* is the measured value of Dy, a representative middle rare earth element (REE), compared with the value interpolated between La and Yb on a REE plot. It is essentially a measure of the 'concavity' of a REE pattern. The use of Dy/Dy* as a proxy for REE pattern shape allows ...
