Assessing Spatial and Temporal Distribution of Algal Blooms Using Gini Coefficient and Lorenz Asymmetry Coefficient

open access: yesFrontiers in Environmental Science, 2022
Algal bloom in an inland lake is characterized by significant spatial and temporal dynamics. Accurate assessment of algal bloom distribution and dynamics is highly required for tracing the causes of and creating countermeasures for algal bloom. Satellite

Algal Blooms in Lakes in China Over the Past Two Decades: Patterns, Trends, and Drivers

open access: yesWater Resources Research, 2023
Many lakes in China suffer from algal bloom problems. However, the spatial and temporal distribution of lacustrine algal blooms at the national scale has not been well characterized.

ALGAL BLOOMS

open access: yesNew Scientist, 2023
When the planktonic algae grow in sufficient numbers and accumulate or cover the water surface of the water body, this condition is known as an algal bloom or water bloom. It gives a distinct colour to the entire water body. The colour of the algae determines the colour of the water blooms. It may be temporary or permanent.

Environmentally driven risk assessment for algal bloom occurrence in shallow lakes

open access: yesEnvironmental Research Letters, 2022
An algal bloom is a complex hydro-biological phenomenon driven by multi-attribute environmental processes and thus is still difficult to predict. In this paper, a comprehensive modelling framework for forecasting algal bloom risks in shallow lakes is ...

Improving Spaceborne GNSS-R Algal Bloom Detection with Meteorological Data

open access: yesRemote Sensing, 2023
Algal bloom has become a serious environmental problem caused by the overgrowth of plankton in many waterbodies, and effective remote sensing methods for monitoring it are urgently needed.

Discrimination of Algal-Bloom Using Spaceborne SAR Observations of Great Lakes in China

open access: yesRemote Sensing, 2018
Although optical remote sensing can intuitively detect algal bloom, it is limited by the weather conditions. Synthetic aperture radar (SAR) is not affected by inadequate weather conditions. According to visual interpretation of SAR images and comparisons

Seasonal variation of aliphatic amines in marine sub-micrometer particles at the Cape Verde islands [PDF]

open access: yes, 2009
Monomethylamine (MA), dimethylamine (DMA) and diethylamine (DEA) were detected at non-negligible concentrations in sub-micrometer particles at the Cap Verde Atmospheric Observatory (CVAO) located on the island of São Vicente in Cape Verde during algal ...
