Wave-induced transport and vertical mixing of pelagic eggs and larvae
Wave-induced transport vertical mixing pelagic eggs and larvae
2014/7/10
The transport of pelagic plankton by wind-driven ocean currents and surface gravity waves is investigated for the example of Northeast Arctic cod eggs and larvae on the coast of northern Norway. Previ...
Oxygen in the deep Strait of Georgia, 1951–2009: The roles of mixing, deep-water renewal, and remineralization of organic carbon
deep Strait of Georgia The roles of mixing
2014/4/2
The concentration of oxygen in the deep Strait of Georgia has declined at a rate of 0.45–1.3 mmol L21

since 1971 and now seasonally approaches thresholds of biological tolerance. The decline ha...
Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
Although isopycnal mixing is undoubtedly important at global and gyre scales, the relative importance of isopycnal and diapycnal mixing on much smaller scales is uncertain. This issue is investigated ...

We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separateand combined effec...
Wind-shear-generated high-frequency internal waves as precursors to mixing in a stratified lake
Wind-shear-generated high-frequency internal waves precursors to mixing stratified lake
2014/4/18
Field data were used to estimate the wavelength, phase speed, direction of propagation, frequency, and the vertical structure of high-frequency internal waves observed on the crests of basin-scale wav...
The role of surface vertical mixing in phytoplankton distribution in a stratified reservoir
The role of surface vertical mixing phytoplankton distribution stratified reservoir
2014/4/23
We investigated convection caused by surface cooling and mixing attributable to wind shear stress and their roles as agents for the transport of phytoplankton cells in the water column by carrying out...
Turbulent mixing and phytoplankton spring bloom development in a deep lake
Turbulent mixing phytoplankton spring bloom development a deep lake
2014/4/22
A one-dimensional (1-D) mechanistic phytoplankton model combined with a 1-D hydrodynamic model was applied to simulate phytoplankton growth during winter and spring in deep monomictic Upper Lake Const...
Light supply, plankton biomass, and seston stoichiometry in a gradient of lake mixing depths
Light supply plankton biomass seston stoichiometry a gradient of lake mixing depths
2014/5/4
We derive from a dynamic model that light availability, phytoplankton density, and the carbon : nutrient ratio of phytoplankton biomass should all be negatively related to mixed surface layer depth, w...
The effect of ultraviolet radiation on freshwater planktonic primary production: The role of recovery and mixing processes
The effect of ultraviolet radiation freshwater planktonic primary production The role of recovery mixing processes
2014/5/13
We used a spectrally resolved kinetic model to calculate ultraviolet radiation (UVR) and photosynthetic active radiation (PAR)-dependent photoinhibitory losses in planktonic primary production in a la...
The rate of inflow and mixing during deep-water renewal in a sill fjord
The rate of inflow mixing during deep-water renewal sill fjord
2014/5/14
We obtained high-resolution data on a deep-water renewal in the basin of Gullmar Fjord, Sweden, using an autonomous profiling platform. In the middle of the fjord, where the platform is anchored, rene...
The interplay between upwelling and deep convective mixing in determining the seasonal phytoplankton dynamics in the Gulf of Aqaba: Evidence from SeaWiFS and MODIS
upwelling deep convective mixing seasonal phytoplankton dynamics the Gulf of Aqaba SeaWiFS and MODIS
2014/5/22
In the Gulf of Aqaba, the northeasternmost segment of the Red Sea, phytoplankton blooms are more intense than in other oligotrophic regions (e.g., the Sargasso Sea). In this study, we use multiyear in...
Performance of sinking and nonsinking phytoplankton taxa in a gradient of mixing depths
sinking and non sinking phytoplankton taxa mixing depths
2014/5/21
According to a recent dynamical model, the depth of a well-mixed water column should have contrasting effects on the abundances of sinking and nonsinking phytoplankton taxa. Because of increasing ligh...
Simple mixing criteria for the growth of negatively buoyant phytoplankton
mixing criteria negatively buoyant phytoplankton
2014/5/20
Phytoplankton population dynamics are controlled by the relative rather than absolute timescales of mixing, growth, and loss processes such as sedimentation, grazing, and so on. Here, the vertical dis...
