Inefficient transfer of diatoms through the subpolar Southern Ocean twilight zone [0.03%]
南极亚极地海域浮游植物通过昏暗层的传输效率较低

J R Williams et al.
The Southern Ocean, a region highly vulnerable to climate change, plays a vital role in regulating global nutrient cycles and atmospheric CO2 via the biological carbon pump. Diatoms, photosynthetically active plankton with dense opal skelet...

The date of the Moon-forming impact places an important constraint on Earth's origin. Lunar age estimates range from about 30 Myr to 200 Myr after solar system formation. Central to this age debate is the greater abundance of 182W inferred ...
Inhibition of phototrophic iron oxidation by nitric oxide in ferruginous environments [0.03%]
硝酸盐氮对含铁热液环境的影响研究

Verena Nikeleit et al.
Anoxygenic phototrophic Fe(II) oxidizers (photoferrotrophs) are thought to have thrived in Earth's ancient ferruginous oceans and played a primary role in the precipitation of Archaean and Palaeoproterozoic (3.8-1.85-billion-year-old) bande...

Since the 1970s, Arctic sea ice has undergone unprecedented change, becoming thinner, less extensive and less resilient to summer melt. Snow's high albedo greatly reduces solar absorption in sea ice and the upper ocean, which mitigates sea-...

Hotspot lavas exhibit chemical heterogeneity, much of which is ascribed to heterogeneous deep mantle sources that contain various components with distinct composition, origin and age. However, characterizing primary melt compositions and ma...
Spatial variability in Arctic-boreal fire regimes influenced by environmental and human factors [0.03%]
环境和人文因素对北极- boreal火灾频度与强度的影响导致极地地区野火季节的地域差异性增强
Rebecca C Scholten,Sander Veraverbeke,Yang Chen et al.
Rebecca C Scholten et al.
Wildfire activity in Arctic and boreal regions is rapidly increasing, with severe consequences for climate and human health. Regional long-term variations in fire frequency and intensity characterize fire regimes. The spatial variability in...
Regional variations in relative sea-level changes influenced by nonlinear vertical land motion [0.03%]
由非线性垂直地运动引起的区域相对海平面变化差异
Julius Oelsmann,Marta Marcos,Marcello Passaro et al.
Julius Oelsmann et al.
Vertical land movements can cause regional relative sea-level changes to differ substantially from climate-driven absolute sea-level changes. Whereas absolute sea level has been accurately monitored by satellite altimetry since 1992, there ...
Substantial contribution of transported emissions to organic aerosol in Beijing [0.03%]
传输污染物对北京有机气溶胶有重要贡献
Kaspar R Daellenbach,Jing Cai,Simo Hakala et al.
Kaspar R Daellenbach et al.
Haze in Beijing is linked to atmospherically formed secondary organic aerosol, which has been shown to be particularly harmful to human health. However, the sources and formation pathways of these secondary aerosols remain largely unknown, ...
Uplift of the Tibetan Plateau driven by mantle delamination from the overriding plate [0.03%]
Tibetan高原的抬升源于俯冲板块下部地幔的拆离
Yuan Xie,Attila Balázs,Taras Gerya et al.
Yuan Xie et al.
The geodynamic evolution of the Tibetan Plateau remains highly debated. Any model of its evolution must explain the plateau's growth as constrained by palaeo-altitude studies, the spatio-temporal distribution of magmatic activity, and the l...
Regime shift in secondary inorganic aerosol formation and nitrogen deposition in the rural United States [0.03%]
美国农村地区二次无机气溶胶形成和氮沉降的制度转变
Da Pan,Denise L Mauzerall,Rui Wang et al.
Da Pan et al.
Secondary inorganic aerosols play an important role in air pollution and climate change, and their formation modulates the atmospheric deposition of reactive nitrogen (including oxidized and reduced nitrogen), thus impacting the nitrogen cy...
