Benthic Dissolved Silicon and Iron Cycling at Glaciated Patagonian Fjord Heads [0.03%]
冰川巴塔哥尼亚峡湾头溶解硅和铁的底质循环
Hong Chin Ng,Jon R Hawkings,Sebastien Bertrand et al.
Hong Chin Ng et al.
Glacier meltwater supplies silicon (Si) and iron (Fe) sourced from weathered bedrock to downstream ecosystems. However, the extent to which these nutrients reach the ocean is regulated by the nature of the benthic cycling of dissolved Si an...
Understanding the Role of Terrestrial and Marine Carbon in the Mid-Latitude Fjords of Scotland [0.03%]
了解苏格兰中纬度峡湾中陆地和海洋碳的作用
C Smeaton,W E N Austin
C Smeaton
The sediments within fjords are critical components of the mid- to high-latitude coastal carbon (C) cycle, trapping and storing more organic carbon (OC) per unit area than other marine sedimentary environments. Located at the land-ocean tra...
Mineral Soils Are an Important Intermediate Storage Pool of Black Carbon in Fennoscandian Boreal Forests [0.03%]
矿物土壤是芬诺斯堪的纳维亚森林中重要的一类中间储存池形式的黑碳库
Johan A Eckdahl,Pere Casal Rodriguez,Jeppe A Kristensen et al.
Johan A Eckdahl et al.
Approximately 40% of earth's carbon (C) stored in land vegetation and soil is within the boreal region. This large C pool is subjected to substantial removals and transformations during periodic wildfire. Fire-altered C, commonly known as p...

Haidi Chen et al.
The deep ocean releases large amounts of old, pre-industrial carbon dioxide (CO2) to the atmosphere through upwelling in the Southern Ocean, which counters the marine carbon uptake occurring elsewhere. This Southern Ocean CO2 release is rel...
Influence of Seasonal Variability in Flux Attenuation on Global Organic Carbon Fluxes and Nutrient Distributions [0.03%]
沉降通量衰减的季节变化对全球有机碳输送及营养物质分布的影响
Francisco de Melo Viríssimo,Adrian P Martin,Stephanie A Henson
Francisco de Melo Viríssimo
The biological carbon pump is a key component of the marine carbon cycle. This surface-to-deep flux of carbon is usually assumed to follow a simple power law function, which imposes that the surface export flux is attenuated throughout subs...
Toward a Global Model for Soil Inorganic Phosphorus Dynamics: Dependence of Exchange Kinetics and Soil Bioavailability on Soil Physicochemical Properties [0.03%]
基于土壤理化性质的全球土壤无机磷模型：交换动力学和土壤生物有效性的依赖性研究
Ying-Ping Wang,Yuanyuan Huang,Laurent Augusto et al.
Ying-Ping Wang et al.
The representation of phosphorus (P) cycling in global land models remains quite simplistic, particularly on soil inorganic phosphorus. For example, sorption and desorption remain unresolved and their dependence on soil physical and chemica...
Attribution of Space-Time Variability in Global-Ocean Dissolved Inorganic Carbon [0.03%]
海洋无机碳时空变异性及其归因研究进展
Dustin Carroll,Dimitris Menemenlis,Stephanie Dutkiewicz et al.
Dustin Carroll et al.
The inventory and variability of oceanic dissolved inorganic carbon (DIC) is driven by the interplay of physical, chemical, and biological processes. Quantifying the spatiotemporal variability of these drivers is crucial for a mechanistic u...
Probing the Bioavailability of Dissolved Iron to Marine Eukaryotic Phytoplankton Using In Situ Single Cell Iron Quotas [0.03%]
利用原位单细胞铁配额探测溶解铁在真核藻类体内的生物可利用性
Yeala Shaked,Benjamin S Twining,Alessandro Tagliabue et al.
Yeala Shaked et al.
We present a new approach for quantifying the bioavailability of dissolved iron (dFe) to oceanic phytoplankton. Bioavailability is defined using an uptake rate constant (kin-app) computed by combining data on: (a) Fe content of individual i...
Biogeographical Classification of the Global Ocean From BGC-Argo Floats [0.03%]
基于BGC-Argo浮标全球海洋生物地理分类
Nicholas Bock,Marin Cornec,Hervé Claustre et al.
Nicholas Bock et al.
Biogeographical classifications of the global ocean generalize spatiotemporal trends in species or biomass distributions across discrete ocean biomes or provinces. These classifications are generally based on a combination of remote-sensed ...

Colleen A Durkin et al.
To better quantify the ocean's biological carbon pump, we resolved the diversity of sinking particles that transport carbon into the ocean's interior, their contribution to carbon export, and their attenuation with depth. Sinking particles ...
