Evidence of warming effects on phytoplankton productivity rates and their dependence on eutrophication status
warming effects phytoplankton productivity rates eutrophication status
2014/4/17
Using 31-yr data from measurements in a lake that has experienced change in eutrophication status, I showed that the effects of global warming on chlorophyll a (Chl a)–normalized maximum rates of phot...
Body size dependence of euphausiid spatial patchiness
euphausiid spatial patchiness Body size
2014/4/16
We analyzed size-dependent variations in spatial patchiness of the eight numerically dominant euphausiid
species in the California Current System (Euphausia pacifica, Nematoscelis difficilis, Nyctiph...
Optimal Power-Law Description of Oceanic Whitecap Coverage Dependence on Wind Speed
Optimal Power-Law Description Oceanic Whitecap Coverage Dependence Wind Speed
2009/2/19
The optimal power-law expression for the dependence of oceanic whitecap coverage fraction W on 10 m elevation wind speed U as determined by ordinary least squares fitting applied to the combined white...
An Eddy-Resolving Numerical Model of the Ventilated Thermocline：Time Dependence
Eddy-Resolving Numerical Model Ventilated Thermocline Time Dependence
2009/1/7
A primitive equation, eddy-resolving numerical model is used to study the inherent time scales of variability in the subtropical ocean, assuming temporally constant surface forcing. Three primary scal...
Depth Dependence of Bottom Stress and Quadratic Drag Coefficient for Barotropic Pressure-Driven Currents
Bottom Stress Barotropic Pressure-Driven Currents Quadratic Drag Coefficient
2009/1/6
A level 2½ turbulence closure model is used to investigate the dependence on water depth H of bottom stress τb and quadratic drag coefficient Cd for a steady barotropic pressure-driven current ...
Distribution of the wind stress over the oceans is usually estimated by using a bulk formula. It contains the squared 10-m wind speed multiplied by the drag coefficient, which has been assumed in many...
Depth Dependence and Mass Transport of Recirculating Midlatitude Gyres
Depth Dependence Mass Transport Mass Transport
2008/12/23
The northwest corners of the major ocean basins are characterized by seaward jets, flanked by tight, nonlinear gyres exhibiting closed potential vorticity contours. At deep levels, isolated from surfa...
On the Dependence of Sea Surface Roughness on Wind Waves
Sea Surface Roughness Wind Waves
2008/10/27
The influence of wind waves on the momentum transfer (wind stress) between the atmosphere and sea surface was studied using new measured data from the RASEX experiment and other datasets compiled by D...
Effects of Stratification and Bottom Topography on the Kuroshio Path Variation South of Japan. Part I: Dependence of the Path Selection on Velocity
Stratification Bottom Topography Kuroshio Path Variation
2008/7/22
Numerical experiments are executed using a two-layer inflow–outflow ocean model with simplified geometry to investigate the effects of stratification and bottom topography on the path variation of the...
Coccolith strontium to calcium ratios in Emiliania huxleyi: The dependence on seawater strontium and calcium concentrations
Coccolith strontium Emiliania huxleyi seawater strontium
2014/4/23
In recent studies the Sr/Ca ratio of coccolithophore calcite was used as a proxy for past coccolithophore growth
and calcification rates. Since Sr and Ca concentrations in seawater have not rem...
Bloom formation in heterocystic nitrogen-fixing cyanobacteria: The dependence on colony size and zooplankton grazing
Bloom formation heterocystic nitrogen-fixing cyanobacteria The dependence on colony size zooplankton grazing
2014/5/19
The success of filamentous nitrogen (N)-fixing cyanobacteria in productive, transiently N-limited freshwaters reflects, in large part, their ability to produce and sustain the activities of specialize...
Light dependence of selenium uptake by phytoplankton and implications for predicting selenium incorporation into food webs
Light dependent selenium uptake phytoplankton implications predicting selenium incorporation food webs
2014/5/14
The potentially toxic element selenium is first concentrated from solution to a large but highly variable degree by algae and bacteria before being passed on to consumers. The large loads of abiotic a...
Control of zooplankton dependence on allochthonous organic carbon in humic and clear-water lakes in northern Sweden
zooplankton dependence allochthonous organic carbon
2014/5/20
We compared the stable carbon isotopic composition (d
13
C) of crustacean zooplankton with that of potential
carbon sources in 15 lakes in northern Sweden with different dissolved organic carbon (D...
