Fluorescence Efficiency of Surface Seawater as a Function of Excitation and Emission Wavelength
Excitation and Emission Wavelength Surface Seawater
2015/8/19
Fluorescence of natural waters has often been employed in attempts to quantify dissolved chromophores. However, it has not always been recognized that the intensity of fluorescence obtained from a giv...
Functional response of carbon absorption efficiency in the pelagic calanoid copepod Acartia tonsa
Functional response carbon absorption efficiency the pelagic calanoid copepod Acartia tonsa
2014/4/17
We constructed a general relationship between prey concentration and absorption efficiency (AE; previously termed assimilation efficiency) in the cosmopolitan calanoid copepod Acartia tonsa. The relat...
Organic carbon burial efficiency in lake sediments controlled by oxygen exposure time and sediment source
Organic carbon burial efficiency lake sediments controlled oxygen exposure time sediment source
2014/4/17
We compared the burial efficiency of organic carbon (buried OC : depositedOC) in a diverse set of 27 different sediments from 11 lakes, focusing on the potential effects of organic matter source, oxyg...

atmosphere–ocean general circulation models Seasonal Cycle
2009/1/10
The asynchronous coupling schemes used in the seasonal, coupled atmosphere–ocean general circulation models (A/O GCMs) of Manabe et al. 1979 and Washington et al. 1980 are tested in the seasonal, coup...
Computational Efficiency and Accuracy of Methods for Asynchronously Coupling Atmosphere–Ocean Climate Models. Part I：Testing with a Mean Annual Model
Computational Efficiency Atmosphere–Ocean Climate Mean Annual Model
2009/1/10
Using the mean annual, globally-averaged, coupled atmosphere–ocean energy balance model of Harvey and Schneider, the effect on the transient climate response to a step function solar constant increase...

North Atlantic Tracer Release Experiment turbulent kinetic energy
2008/12/3
Microstructure data from the North Atlantic Tracer Release Experiment (NATRE) are presented, providing detailed profiles of the thermal variance χ in the upper 360 m of the Canary Basin for the fall a...
On the Efficiency of Baroclinic Eddy Heat Transport across Narrow Fronts
Efficiency of Baroclinic Eddy Narrow Fronts Heat Transport
2008/10/23
A simple theory is developed that relates the amplitude of eddy heat (or density) flux across a narrow front to the basic frontal parameters. By assuming that heat is transported primarily by baroclin...
The Efficiency of Mixing in Turbulent Patches: Inferences from Direct Simulations and Microstructure Observations
Efficiency Turbulent Patches Direct Simulations Microstructure Observations
2008/8/5
The time evolution of mixing in turbulent overturns is investigated using a combination of direct numerical simulations (DNS) and microstructure profiles obtained during two field experiments. The foc...
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
2014/4/23
We present surface estimates of bacterial respiration, bacterial heterotrophic production (BHP), and bacterial growth efficiency (BGE), and their relationship with nutrient availability, along a troph...
Efficiency of a phytoplankton-based and a bacterial-based food web in a pelagic marine system
Efficiency of a phytoplankton-based bacterial-based food web pelagic marine system
2014/4/22
The food web efficiency in two contrasting food webs, one phytoplankton based and one bacteria based, was studied in a mesocosm experiment using seawater from the northern Baltic Sea. Organisms includ...
Maximum photosynthetic efficiency of size-fractionated phytoplankton assessed by 14C uptake and fast repetition rate fluorometry
Maximum photosynthetic efficiency size-fractionated phytoplankton assessed 14C uptake fast repetition rate fluorometry
2014/5/13
Under high nutrient concentrations and sufficient light conditions, large phytoplankton may display higher photosynthetic efficiency than smaller cells. This is unexpected since smaller phytoplankton,...
