Phosphorus enrichment and carbon depletion contribute to high Microcystis biomass and microcystin concentrations in Ugandan lakes
Phosphorus enrichment carbon depletion contribute
2014/4/2
We investigated the factors influencing cyanobacterial biomass and microcystin (MC) concentrations in several
Ugandan lakes from September 2008 to February 2009. We characterized thermal structure, l...
Chemical diversity and spatial variability in myriad lakes in Nhecolaˆndia in the Pantanal wetlands of Brazil
Chemical diversity spatial variability Pantanal wetlands
2014/4/2
Nearly 15,000 shallow, saline or freshwater lakes and ponds coexist in close proximity in the Nhecolaˆndia, a
24,000 km2
subregion of the Pantanal wetland in Brazil. This study aims to understa...
The response of a simple Great Lake model to wind stress is studied theoretically. The model is of constant depth and of circular shape, continuously stratified with a thermocline region of linear den...
Transverse Internal Seiches in Large Oblong Lakes and Marginal Seas
Transverse Internal Seiches Large Oblong Lakes Marginal Seas
2009/4/2
The generation by unsteady winds of standing oscillations on the pycnocline of lakes and enclosed seas, which are much longer than they are wide, is studied on the assumption that end effects are negl...
Water motion in the barotropic mode, directly forced by suddenly imposed wind stress, is investigated in basins with arbitrary topography, but paying special attention to long basins, in which the dep...
Short-Period Variations in a Great Lakes Coastal Current by Aerial Photogrammetry
Short-Period Variations Short-Period Variations
2009/3/24
Measurements of the surface velocity structure off the Keweenaw Peninsula of Lake Superior were obtained in 1971 and 1972, using aerial photography to track surface drift cards. Variations in the curr...
The classification of Mixed-Layer Dynamics of Lakes of Small to Medium Size
Mixed-Layer Dynamics Lakes Medium Size
2009/2/18
An analysis of the time scales of processes relevant to wind mixing in lakes indicates that the response of a lake to wind may be classified into four regimes with respect to thermocline deepening beh...
Structure of the Flow within the Coastal Boundary Layer of the Great Lakes
Coastal Boundary Layer Great Lakes
2009/2/10
Properties of the nearshore flow have been observed in some detail in Douglas Point, Lake Huron. Time series flow data obtained from a network of current meters deployed in a coastal chain perpendicul...
On the Nature of Turbulence in a Stratified Fluid. Part II：Application to Lakes
buoyancy flux Stratified Fluid Lakes
2008/12/23
A strong debate has continued for a number of years over the magnitude of the ratio of the buoyancy flux b to the rate of production of turbulent kinetic energy from the mean velocity sheer. This rati...
On the Net Cyclonic Circulation in Large Stratified Lakes
Net Cyclonic Circulation Large Stratified Lakes azimuthal flow
2008/10/31
Schwab et al. have investigated a possible cause of long-term cyclonic circulation often observed in stratified lakes. They conclude that the adiabatic boundary condition applied to the bottom boundar...
Inertial oscillations and related internal beat pulsations and surges in Lakes Michigan and Ontario
Inertial oscillations beat pulsations and surges Lakes Michigan Ontario
2014/5/5
Records of water temperature, current, and wind, made during campaigns on Lakes Michigan 1963 and Ontario 1972, are searched for inertial responses to wind action: (i) circle-tracking currents; and (i...
Influence of inlet bacteria on bacterioplankton assemblage composition in lakes of different hydraulic retention time
bacterioplankton assemblage composition lakes
2014/5/14
The influence of inlet bacteria on the assemblage composition of bacterioplankton was investigated in two Swedish forest lakes of different hydraulic retention time. Assemblage composition of th...

Calculation of spectral weighting functions for the solar photobleaching of chromophoric dissolved organic matter in temperate lakes
spectral weighting functions solar photobleaching chromophoric dissolved organic matter temperate lakes
2014/6/9
The effect of solar radiation on the dissolved absorption coefficient (αCDOM[γ]), which reflects the concentration of chromophoric dissolved organic matter (CDOM), was investigated in several lakes ne...
