Rapid photoacclimation during episodic deep mixing augments the biological carbon pump [0.03%]
快速的光适应在间歇性深水混合中促进生物碳泵作用
W Bryce Penta,James Fox,Kimberly H Halsey
W Bryce Penta
Episodic deep mixing events are one component of the biological carbon pump that physically transports organic carbon into the mesopelagic. Episodic deep mixing also disrupts summertime thermal stratification thereby changing the light fiel...
Spatial variability of prokaryotic and viral abundances in the Kermadec and Atacama Trench regions [0.03%]
凯尔马德克和阿塔卡马海沟区域微生物丰度的空间差异性

Clemens Schauberger et al.
Hadal trenches represent the deepest part of the ocean and are dynamic depocenters with intensified prokaryotic activity. Here, we explored the distribution and drivers of prokaryotic and viral abundance from the ocean surface and 40 cm int...
In situ recovery of bivalve shell characteristics after temporary exposure to elevated p CO2 [0.03%]
升高pCO2环境下暂时暴露后双壳纲软体动物外壳特征的原位恢复

Jason Grear et al.
Ocean uptake of carbon dioxide (CO2) is causing changes in carbonate chemistry that affect calcification in marine organisms. In coastal areas, this CO2-enriched seawater mixes with waters affected by seasonal degradation of organic materia...
The wind-driven formation of cross-shelf sediment plumes in a large lake [0.03%]
大湖shelf横跨沉积羽的形成风驱动形成货架横跨沉积羽在大型湖泊中驱动形成

Paul McKinney
Wind-driven turbidity plumes frequently occur in the western arm of Lake Superior and may represent a significant cross shelf transport mechanism for sediment, nutrient and biota. Here we characterize a plume that formed in late April 2016 ...
Turbulence in a small boreal lake: Consequences for air-water gas exchange [0.03%]
小北部湖泊中的湍流及其对空气-水气体交换的影响
Sally MacIntyre,David Bastviken,Lars Arneborg et al.
Sally MacIntyre et al.
The hydrodynamics within small boreal lakes have rarely been studied, yet knowing whether turbulence at the air-water interface and in the water column scales with metrics developed elsewhere is essential for computing metabolism and fluxes...
Under-ice mesocosms reveal the primacy of light but the importance of zooplankton in winter phytoplankton dynamics [0.03%]
冰下中宇宙实验揭示了光照在冬季浮游植物动力学中的首要地位，但底栖生物也起重要作用

Factors that regulate planktonic communities under lake ice may be vastly different from those during the open-water season. Expected changes in light availability, ice cover, and snowfall associated with climate change have accelerated the...
Physical drivers facilitating a toxigenic cyanobacterial bloom in a major Great Lakes tributary [0.03%]
物理驱动因素促成了一条主要的五大湖支流中的产毒蓝藻水华事件

Paul G Matson et al.
The Maumee River is the primary source for nutrients fueling seasonal Microcystis-dominated blooms in western Lake Erie's open waters though such blooms in the river are infrequent. The river also serves as source water for multiple public ...
The fecal iron pump: Global impact of animals on the iron stoichiometry of marine sinking particles [0.03%]
动物对海洋颗粒物铁计量学的影响：粪便中铁泵的作用
Priscilla K Le Mézo,Eric D Galbraith
Priscilla K Le Mézo
The impact of marine animals on the iron (Fe) cycle has mostly been considered in terms of their role in supplying dissolved Fe to phytoplankton at the ocean surface. However, little attention has been paid to how the transformation of inge...
Mesozooplankton taurine production and prokaryotic uptake in the northern Adriatic Sea [0.03%]
北部亚得里亚海中浮游动物牛磺酸的产生及细菌对其的吸收作用研究
Elisabeth L Clifford,Daniele De Corte,Chie Amano et al.
Elisabeth L Clifford et al.
Dissolved free taurine, an important osmolyte in phytoplankton and metazoans, has been shown to be a significant carbon and energy source for prokaryotes in the North Atlantic throughout the water column. However, the extent of the coupling...

The West Antarctic Peninsula (WAP) is a highly productive polar ecosystem where phytoplankton dynamics are regulated by intense bottom-up control from light and iron availability. Rapid climate change along the WAP is driving shifts in the ...
