查询词典 carbon cycle

The eight major research topics are :①understanding coremantle processes, by deep drilling into a large oceanic plateau in the Western Pacific;②detailed investigation of material circulation during greenhouse Earth, and the transition process from greenhouse to icehouse environments, by drilling Cretaceous to Cenozoic sediments in the Pacific,③understanding the process of continental crust formation by deep drilling into oceanic arc,④Understanding the process of oceanic lithosphere formation by deep drilling of the back arc spreading system,⑤understanding of continentoceanatmosphere linkage, by drilling in the marginal seas and continental slopes of Asia,⑥investigation of the carbon cycle and the deep biosphere in accretionary prisms,⑦investigation of the mechanism and cycles of great earthquakes, tectonics, and mass circulation in convergent plate margins,and ⑧biology of extreme microorganisms living in deep accretionary prism environment.Keywords : Japan IODP Drilling Scientific goals.

The built carbon cycle model had been used to simulate the surface distributions, vertical distributions and the isogram distributions along the meridian of various chemical species in the Indian Ocean.

As observed in the Pleistocene, thick intervals of negative δ13C values occur in the Neoproterozoic but are considered to record profound perturbations to the global marine carbon cycle unique to the Neoproterozoic rather than being considered in terms of normal mixed meteoric/marine lithification or decarboxylation.

更新世的观察表明，新元古代存在着一个较长时期的δ13C负值，这些负值记录了全球海洋碳同位素的波动循环是新元古代独有的，而并非通常意义下的大气海洋水混合产生的岩化作用和脱羧基作用。

Rather than being perturbations to the carbon cycle, widely reported decreases in 13C/12C in Neoproterozoic carbonates are more easily interpreted in the same way as is done for Phanerozoic examples.

被广泛报道的新元古代碳酸盐中13C/12C比例的下降并非是碳周期的波动，它们更容易通过与显生宙样品类比来理解。

The Heartbeat of the Oligocene Climate System - Marine sediments from 34 to 21 million years ago reveal an intricate response to orbital forcing on the part of Earth's climate, carbon cycle, and ice sheets.Authors: Heiko Plike, Richard D.

渐心跳的气候系统--从1934年至1921年海洋沉积物万多年前就揭示了错综复杂的轨道，迫使一部分地球气候、碳循环、冰sheets.authors：plike时Heiko理查德丁诺里斯的Jens澳海尔勒保罗威尔逊甲、海伦coxall悦、加罗林老义形式尼古拉j。

Then A simple carbon cycle model is built through the mass balance calculation.

通过质量平衡计算，建立了草海区域碳循环的简单模式。

Pelagic tunicates are an important group of zooplankton in the subtropic and tropic waters. Distribution and variation of their species richness and abundance are influenced by physical and biological factors. Pelagic tunicates play an important role in marine food web carbon cycle as they feed on bacterioplankton and pico-and nano-phytoplankton and meanwhile are preys for commercial animals.

浮游被囊动物是热带和亚热带海域重要的浮游动物类群，种类和数量的分布变化受物理和生物环境因素的影响；它一方面大量摄食浮游细菌和微小浮游植物，另一方面被一些经济动物摄食，因此在海洋食物链的传递和生态系统的物质循环中占有重要位置。

The relationship between carbon cycle in terrestrial ecosystem and globe change is the key of environment issues.

陆地碳循环与全球气候变化之间的相互关系是当前环境问题研究的核心内容之一。

Lots of achievements in soil carbon cycle of conservation tillage have been made in the past years.

国内外在保护性耕作上对土壤碳循环等方面取得了丰硕的成果。

Photosynthetically Active Radiation is an important parameter in models of ecosystem dynamics and carbon cycle.

中文摘要：提出基于MODIS大气和地表产品反演高精度复杂地形下的光合有效辐射模型。
