Effect of Weather-Related Episodic Events over Chlorophyll-a in a Shallow Lake: an Analysis Based on High-Frequency Data
(Interperiodica, 2021-07-08)
With conventional monitoring at low-frequency, biological responses to weather-related events are missed. In this paper, we examine the chlorophyll-a concentrations in a shallow lake using high-frequency data from an in ...
Development of an empirical model for chlorophyll-a and Secchi Disk Depth estimation for a Pampean shallow lake (Argentina)
(National Authority Remote Sensing & Space Sciences, 2017-04-20)
Shallow Pampean lakes are located in the most productive plain of Argentina. They are highly variable in salinity, turbidity and surface area. Laguna Chascomús has been monitored as a representative example of them. We ...
Crustacean zooplankton species richness in Chilean lakes and ponds (23 degrees-51 degrees S)

Assessment of remotely-sensed sea-surface temperature and chlorophyll-a concentration in San Matías Gulf (Patagonia, Argentina)
(Pergamon-Elsevier Science Ltd, 2013-01)
Field measurements of surface temperature and chlorophyll-a concentration were used to evaluate for the first time the performance of the standard sea surface temperature and chlorophyll-a algorithms of the Moderate ...
Distribution and abundance of Euphausia mucronata: development stages and its relationship with temperature and chlorophyll-a concentration
(Pontificia Universidad Católica de Valparaíso, 2021)
Effect of herbicides based on glyphosate on the photosynthesis of green macroalgae in tropical lotic environments
(2021-09-01)
The susceptibility of aquatic environments to contamination by glyphosate has been of worldwide con-cern, mainly since this herbicide affects important physiological processes such as photosynthesis. Considering this, we ...
Estimation of chlorophyll-a concentration using Landsat 8 in the Cassaffousth reservoir
(IWA Publishing, 2019-11)
The physico-chemical and biological composition of a reservoir's effluents directly influences water quality. The values of variables such as high values of concentrations of chlorophyll-a (Chl-a) are indicators of pollution. ...
Spatial variability of chlorophyll-a and abiotic variables in a river–floodplain system during different hydrological phases
(Springer, 2013-06)
Chlorophyll-a (Chl-a) and abiotic variables were measured in the main channel and floodplain waterbodies of the Middle Paraná River to analyse the system dynamics and to assess their spatial variability during different ...
Assessing the potential of integrating Landsat sensors for estimating chlorophyll-a concentration in a reservoir
(IWA Publishing, 2018-10)
Landsat satellites, 5 and 7, have significant potential for estimating several water quality parameters, but to our knowledge, there are few investigations which integrate these earlier sensors with the newest and improved ...
Revisiting in Situ Chlorophyll-a Data Along the Coast in North-Central Chile Considering Multiscale Environmental Variability
