Scientists find no direct link between North Atlantic Ocean currents, New England coast sea level（图）
Scientists North Atlantic Ocean currents New England coast sea level
2019/10/28
A new study by NSF-funded scientists at the Woods Hole Oceanographic Institution clarifies the influence of major currents in the North Atlantic Ocean on sea level along the coast of the northeastern ...
Sea snakes are an evolutionary success story. With about 70 species, they’re the most diverse reptile group in the ocean, outnumbering sea turtle species 10-to-1.They sport a range of physical adaptat...
No laughing matter: Nitrous oxide rose at end of last ice age
No laughing matter Nitrous oxide end of last ice age
2014/12/30
CORVALLIS, Ore. – Nitrous oxide (N2O) is an important greenhouse gas that doesn’t receive as much notoriety as carbon dioxide or methane, but a new study confirms that atmospheric levels of N2O rose s...
No limit? The multiphasic uptake of silicic acid by benthic diatoms
No limit multiphasic uptake silicic acid benthic diatoms
2014/4/18
Silicic-acid uptake kinetics for a field population of benthic diatoms were examined using a radioisotope tracer over a concentration range of 0–300mmol L21. The microphytobenthos half saturation cons...
No empirical evidence for community-wide top-down control of prey fish density and size by fish predators in lakes
No empirical evidence community-wide top-down control prey fish density size by fish predators in lakes
2014/4/16
I tested relationships between fish predator and prey densities or size across 66 lakes of the European temperate zone, covering mean depths between 1 and 22 m and a phytoplankton biomass range betwee...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...
运用228Ra-NO-3法测定南沙海域的新生产力
南沙海域 新生产力
2009/2/7
运用MnO2纤维富集-228Ac b计数法测定了南沙海域两个测站3个时间点水柱的228Ra比活度, 得其值介于0.38至 3.60 Bq×m-3. 发现228Ra的分布能满足稳态条件. 采用一维稳态模型, 以228Ra-NO- 3法测得测站NS97-43, NS99-53(T1)和NS99-53(T2)的新生产力分别为4.4, 5.1和5.7 mmolC·m-2·d-1. 结合初级生产力的文献报道...
On the Ocean’s Large-Scale Circulation near the Limit of No Vertical Mixing
Large-Scale Circulation No Vertical Mixing Limit
2008/10/27
By convention, the ocean’s large-scale circulation is assumed to be a thermohaline overturning driven by the addition and extraction of buoyancy at the surface and vertical mixing in the interior. Pre...
Colony formation in Scenedesmus: No contribution of urea in induction by a lipophilic Daphnia exudate
Colony formation in Scenedesmus No contribution of urea in induction a lipophilic Daphnia exudate
2014/6/10
The common green alga Scenedesmus may respond morphologically to numerous environmental factors. The formation of colonies in Scenedesmus resulting from exposure to grazer (Daphnia) excreta is of part...
