A modeling analysis of spatial statistical indicators of thresholds for algal blooms

open access: yesLimnology and Oceanography Letters, 2018
Predicting algal blooms both within and among aquatic ecosystems is important yet difficult because multiple factors promote and suppress blooms. Statistical indicators (e.g., variance and autocorrelation) based on time series can provide warning of ...

Using Remote Sensing to Monitor Aquatic Vegetation and Algal Blooms in Lakes in Yellow River Basin

open access: yesGuan'gai paishui xuebao, 2022
【Background and objective】 Global warming and anthropogenic activities will change ecological functions of lakes, resulting in eutrophication and algal blooms, for example.

MODIS-Satellite-Based Analysis of Long-Term Temporal-Spatial Dynamics and Drivers of Algal Blooms in a Plateau Lake Dianchi, China

open access: yesRemote Sensing, 2019
Algal blooms in eutrophic lakes have been a global issue to environmental ecology. Although great progress on prevention and control of algae have been made in many lakes, systematic research on long-term temporal-spatial dynamics and drivers of algal ...

A turbulent diatom vs dinoflagellate phytoplankton biomass model [PDF]

open access: yes, 2013
Phytoplankton blooms play an important role in global primary productivity and the dynamics of blooms are of interest to modellers. Diatom dominated phytoplankton blooms followed by dinoflagellate blooms are common in the Southern Benguela, and are often

Tracing the early development of harmful algal blooms with the aid of Lagrangian coherent structures

open access: yes, 2007
Several theories have been proposed to explain the development of harmful algal blooms (HABs) produced by the toxic dinoflagellate \emph{Karenia brevis} on the West Florida Shelf.

Image processing for smart browsing of ocean colour data products and subsequent incorporation into a multi-modal sensing framework [PDF]

open access: yes, 2010
Ocean colour is defined as the water hue due to the presence of tiny plants containing the pigment chlorophyll, sediments and coloured dissolved organic material and so water colour can provide valuable information on coastal ecosystems.

Assessment of Long-Term Watershed Management on Reservoir Phosphorus Concentrations and Export Fluxes. [PDF]

open access: yes, 2018
Source water nutrient management to prevent eutrophication requires critical strategies to reduce watershed phosphorus (P) loadings. Shanxi Drinking-Water Source Area (SDWSA) in eastern China experienced severe water quality deterioration before 2010 ...

The Effect of Algal Blooms on Carbon Emissions in Western Lake Erie: An Integration of Remote Sensing and Eddy Covariance Measurements

open access: yesRemote Sensing, 2017
Lakes are important components for regulating carbon cycling within landscapes. Most lakes are regarded as CO2 sources to the atmosphere, except for a few eutrophic ones.
