Mercury in the Black Sea: New Insights From Measurements and Numerical Modeling [0.03%]
黑海的汞：来自测量和数值模拟的新见解
G Rosati,L E Heimbürger,D Melaku Canu et al.
G Rosati et al.
Redox conditions and organic matter control marine methylmercury (MeHg) production. The Black Sea is the world's largest and deepest anoxic basin and is thus ideal to study Hg species along the extended redox gradient. Here we present new d...
Vertical Distributions of Coccolithophores, PIC, POC, Biogenic Silica, and Chlorophyll a Throughout the Global Ocean [0.03%]
全球海洋浮游植物的垂向分布：钙藻、PIC、POC、生物硅和叶绿素a
William M Balch,Bruce C Bowler,David T Drapeau et al.
William M Balch et al.
Coccolithophores are a critical component of global biogeochemistry, export fluxes, and seawater optical properties. We derive globally significant relationships to estimate integrated coccolithophore and coccolith concentrations as well as...
Controls on the distribution of fluorescent dissolved organic matter during an under-ice algal bloom in the western Arctic Ocean [0.03%]
控制西方北极洋冰下藻类大量繁殖期间荧光溶解有机质分布的因素
Wilson G Mendoza,Elliot L Weiss,Brian Schieber et al.
Wilson G Mendoza et al.
In this study we used fluorescence excitation and emission matrix spectroscopy, hydrographic data, and a self-organizing map (SOM) analysis to assess the spatial distribution of labile and refractory fluorescent dissolved organic matter (FD...

Consistent long-term estimates of fire emissions are important to understand the changing role of fire in the global carbon cycle and to assess the relative importance of humans and climate in shaping fire regimes. However, there is limited...
A multi-year estimate of methane fluxes in Alaska from CARVE atmospheric observations [0.03%]
基于CARVE大气观测的阿拉斯加多年甲烷通量估计
Scot M Miller,Charles E Miller,Roisin Commane et al.
Scot M Miller et al.
Methane (CH4) fluxes from Alaska and other arctic regions may be sensitive to thawing permafrost and future climate change, but estimates of both current and future fluxes from the region are uncertain. This study estimates CH4 fluxes acros...
Global patterns and controls of soil organic carbon dynamics as simulated by multiple terrestrial biosphere models: Current status and future directions [0.03%]
多个陆地生态系统模型模拟的全球土壤有机碳动态及其控制因素：现状与未来方向
Hanqin Tian,Chaoqun Lu,Jia Yang et al.
Hanqin Tian et al.
Soil is the largest organic carbon (C) pool of terrestrial ecosystems, and C loss from soil accounts for a large proportion of land-atmosphere C exchange. Therefore, a small change in soil organic C (SOC) can affect atmospheric carbon dioxi...
Disentangling the contribution of multiple land covers to fire-mediated carbon emissions in Amazonia during the 2010 drought [0.03%]
亚马逊森林在2010年干旱期间火灾导致的碳排放量及其各土地利用类型贡献率估算
Liana Oighenstein Anderson,Luiz E O C Aragão,Manuel Gloor et al.
Liana Oighenstein Anderson et al.
In less than 15 years, the Amazon region experienced three major droughts. Links between droughts and fires have been demonstrated for the 1997/1998, 2005, and 2010 droughts. In 2010, emissions of 510 ± 120 Tg C were associated to fire alo...
Spatial and temporal contrasts in the distribution of crops and pastures across Amazonia: A new agricultural land use data set from census data since 1950 [0.03%]
亚马逊农业用地空间和时间分布差异：自1950年以来的人口普查数据驱动的土地利用数据集
P Imbach,M Manrow,E Barona et al.
P Imbach et al.
Amazonia holds the largest continuous area of tropical forests with intense land use change dynamics inducing water, carbon, and energy feedbacks with regional and global impacts. Much of our knowledge of land use change in Amazonia comes f...
Microbial nitrogen dynamics in organic and mineral soil horizons along a latitudinal transect in western Siberia [0.03%]
西西伯利亚沿纬度梯度的有机层和矿物土层中的微生物氮动力学
Birgit Wild,Jörg Schnecker,Anna Knoltsch et al.
Birgit Wild et al.
Soil N availability is constrained by the breakdown of N-containing polymers such as proteins to oligopeptides and amino acids that can be taken up by plants and microorganisms. Excess N is released from microbial cells as ammonium (N miner...
Biogeochemical control of marine productivity in the Mediterranean Sea during the last 50 years [0.03%]
地中海海洋生产力的生化控制：过去五十年的变化
Diego Macias,Elisa Garcia-Gorriz,Chiara Piroddi et al.
Diego Macias et al.
The temporal dynamics of biogeochemical variables derived from a coupled 3-D model of the Mediterranean Sea are evaluated for the last 50 years (1960-2010) against independent data on fisheries catch per unit effort (CPUE) for the same time...
