Stability of dissolved and soluble Fe(II) in shelf sediment pore waters and release to an oxic water column [0.03%]
shelves中的沉积物孔隙水的溶解和可溶性Fe（II）的稳定性及释放到氧化水体中
J K Klar,W B Homoky,P J Statham et al.
J K Klar et al.
Shelf sediments underlying temperate and oxic waters of the Celtic Sea (NW European Shelf) were found to have shallow oxygen penetrations depths from late spring to late summer (2.2-5.8 mm below seafloor) with the shallowest during/after th...
Oxygen dynamics in shelf seas sediments incorporating seasonal variability [0.03%]
考虑季节变化的陆棚沉积物氧动力学模拟研究
N Hicks,G R Ubbara,B Silburn et al.
N Hicks et al.
Shelf sediments play a vital role in global biogeochemical cycling and are particularly important areas of oxygen consumption and carbon mineralisation. Total benthic oxygen uptake, the sum of diffusive and faunal mediated uptake, is a robu...
An approach for the identification of exemplar sites for scaling up targeted field observations of benthic biogeochemistry in heterogeneous environments [0.03%]
在异质环境中识别示范站点以扩大底栖生物地球化学目标现场观测的规模的方法
C E L Thompson,B Silburn,M E Williams et al.
C E L Thompson et al.
Continental shelf sediments are globally important for biogeochemical activity. Quantification of shelf-scale stocks and fluxes of carbon and nutrients requires the extrapolation of observations made at limited points in space and time. The...
Differential effects of chronic and acute simulated seawater intrusion on tidal freshwater marsh carbon cycling [0.03%]
模拟海水入侵对潮汐淡水沼泽碳循环的长期和短期影响不同

Ellen R Herbert
Tidal freshwater ecosystems experience acute seawater intrusion associated with periodic droughts, but are expected to become chronically salinized as sea level rises. Here we report the results from an experimental manipulation in a tidal ...
Watershed 'Chemical Cocktails': Forming Novel Elemental Combinations in Anthropocene Fresh Waters [0.03%]
人造化合物组合在当代水体中的形成：化学混合的突破性进展
Sujay S Kaushal,Arthur J Gold,Susana Bernal et al.
Sujay S Kaushal et al.
In the Anthropocene1, watershed chemical transport is increasingly dominated by novel combinations elements, which are hydrologically linked together as 'chemical cocktails.' Chemical cocktails are novel because human activities greatly enh...
Spatially Variable Bioturbation and Physical Mixing Drive the Sedimentary Biogeochemical Seascape in the Louisiana Continental Shelf Hypoxic Zone [0.03%]
空间异质搅动和物理混合驱动了路易斯安那大陆架低氧区的底泥生物地球化学格局
Richard Devereux,John C Lehrter,Giancarlo Cicchetti et al.
Richard Devereux et al.
Seasonal hypoxia on the Louisiana continental shelf (LCS) has grown to over 22,000 km2 with limited information available on how low oxygen effects the benthos. Benthic macrofaunal colonization and sediment biogeochemical parameters were ch...
Arsenic and high affinity phosphate uptake gene distribution in shallow submarine hydrothermal sediments [0.03%]
浅海水下热液沉积物中砷和高效吸磷基因的分布规律
Ernest Chi Fru,Nolwenn Callac,Nicole R Posth et al.
Ernest Chi Fru et al.
The toxicity of arsenic (As) towards life on Earth is apparent in the dense distribution of genes associated with As detoxification across the tree of life. The ability to defend against As is particularly vital for survival in As-rich shal...

Flooding is a major disturbance that impacts aquatic ecosystems and the ecosystem services that they provide. Predicted increases in global flood risk due to land use change and water cycle intensification will likely only increase the freq...
Rapid warming and salinity changes in the Gulf of Maine alter surface ocean carbonate parameters and hide ocean acidification [0.03%]
缅因湾快速升温及盐度变化改变表层海洋碳酸盐参数并掩盖海水酸化现象
Joseph E Salisbury,Bror F Jönsson
Joseph E Salisbury
A profound warming event in the Gulf of Maine during the last decade has caused sea surface temperatures to rise to levels exceeding any earlier observations recorded in the region over the last 150 years. This event dramatically affected C...
Spatial variability of organic matter properties determines methane fluxes in a tropical forested peatland [0.03%]
有机物性质的空间变异性决定了热带泥炭森林甲烷通量
N T Girkin,C H Vane,H V Cooper et al.
N T Girkin et al.
Tropical peatland ecosystems are a significant component of the global carbon cycle and feature a range of distinct vegetation types, but the extent of links between contrasting plant species, peat biogeochemistry and greenhouse gas fluxes ...
