Temperature and photoperiod effects on phytoplankton growing under simulated mixed layer light fluctuations
Temperature and photoperiod effects phytoplankton growing simulated mixed layer light fluctuations
2014/4/4
We measured specific growth rates of Stephanodiscus minutulus, Nitzschia acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating and constant light in semi-continuous culture a...
Particle dispersal due to interplay of motions in the surface layer of a small reservoir
surface layer reservoir Particle dispersal
2014/4/16
Horizontal dispersion mechanisms must be well defined in order to determine the origin and fate of
heterogeneous distributions of biogeochemical material. Here data from an intensive field campaign i...
Convergences and divergences and thin layer formation and maintenance
Convergences divergences thin layer formation maintenance
2014/4/22
The formation and maintenance of thin layers in the presence of turbulent diffusion is considered through the development of a formal framework that evaluates the balance between convergence mechanism...
Viruses as mortality agents of picophytoplankton in the deep chlorophyll maximum layer during IRONAGES III
Viruses mortality agents picophytoplankton in the deep chlorophyll maximum layer IRONAGES III
2014/4/21
We report viral-induced mortality rates of the picoeukaryotic (two size classes) and prokaryotic (cyanobacteria Prochlorococcus and Synechococcus) phytoplankton during a cruise in the oligotrophic sub...
Effect of the diffusive boundary layer on benthic mineralization and O2 distribution: A theoretical model analysis
Effect of the diffusive boundary layer benthic mineralization O2 distribution: A theoretical model analysis
2014/4/23
On the basis of a dynamic diagenetic model, we evaluate and discuss the effect of the diffusive boundary layer (DBL) on benthic O2 exchange and O2 consuming pathways. The analysis documents that the D...
Boundary layer turbulence and flow structure over a fringing coral reef
Boundary layer turbulence flow structure over fringing coral reef
2014/5/5
Measurements of velocity and rates of turbulence were made across a fringing coral reef in the Gulf of Aqaba, Red Sea, to determine the effect that the rough topography has on boundary layer mixing an...
The origin of the fluid mud layer in Lake Apopka, Florida
the fluid mud layer Lake Apopka Florida
2014/5/9
Since it switched from a macrophyte-dominated state to a turbid, algal-dominated state in 1947, Lake Apopka has developed a layer of flocculent sediments with characteristics of fluid mud covering mos...
Transmission of oxygen concentration fluctuations through the diffusive boundary layer overlying aquatic sediments
oxygen concentration fluctuations diffusive boundary layer aquatic sediments
2014/5/14
Even though the O2 concentration in the diffusive boundary layer overlying natural aquatic sediments usually varies over time, microprofiles with little or no error bars are abundant in the literature...
The role of small-scale sediment topography for oxygen flux across the diffusive boundary layer
The role of small-scale sediment topography oxygen flux across diffusive boundary layer
2014/5/27
At the scale of centimeters or millimeters, marine sediment surfaces are sculptured into complex three-dimensional landscapes. A detailed study of fluxes through the diffusive boundary layer (DBL) the...
Sequential resuspension of protists by accelerating tidal flow: Implications for community structure in the benthic boundary layer
Sequential resuspension protists accelerating tidal flow community structure benthic boundary layer
2014/5/27
We measured resuspension thresholds of protists and bacteria at a subtidal coastal site with in situ flumes and by sampling the benthic boundary layer during tidal accelerations. Heterotrophic nanofla...
What controls the mixed-layer depth in deep-sea sediments? The importance of POC flux
mixed-layer depth deep-sea sediments The importance of POC flux
2014/5/26
The depth of biogenic particle mixing, i.e., the mixed-layer depth (L), is fundamental in models of organic-matter recycling and paleoreconstructions for deep-sea sediments. Factors postulated to cont...
Influences of benthic boundary-layer flow on feeding rates of ciliates and flagellates at the sediment-water interface
benthic boundary-layer flow feeding rates ciliates flagellates sediment-water interface
2014/6/10
Heterotrophic protists are integral to sedimentary food webs, but influences on their activities are poorly understood, especially the role of benthic boundary-layer flow. Effects of flow on ingestion...
Baltic Sea nitrogen fixation estimated from the summer increase in upper mixed layer total nitrogen
Baltic Sea nitrogen fixation the summer increase upper mixed layer total nitrogen
2014/6/9
We estimated nitrogen fixation from the increase in total nitrogen (N2 gas excluded) in the upper 20 m during the summer biomass increase of heterocystous filamentous cyanobacteria at the off-shore La...
