Improvement of Algal Bloom Identification Using Satellite Images by the Algal Spatial Monitoring and Machine Learning Analysis in a New Dam Reservoir [PDF]

open access: yesGeo Data, 2023
Algal blooms are major issues and an ongoing cause of water quality problems in inland waters globally. In the case of harmful algal blooms, the water temperature rises after nitrogen and phosphorus inflow, which occurs in the summer, is the main cause ...

Phytoplankton-associated bacterial community composition and succession during toxic diatom bloom and non-bloom events

open access: yesFrontiers in Microbiology, 2016
Pseudo-nitzschia blooms often occur in coastal and open ocean environments, sometimes leading to the production of the neurotoxin domoic acid that can cause severe negative impacts to higher trophic levels.

Expanding toxic algal blooms [PDF]

open access: yesScience, 2017
Ocean Ecology Ocean temperatures in the North Atlantic and North Pacific oceans have increased in recent decades, particularly in coastal areas. This has been associated with increased algal blooms and, where these blooms include algal species that produce biotoxins, the potential for increases in cases of paralytic and diarrhetic shellfish poisoning ...

Probabilistic prediction of algal blooms from basic water quality parameters by Bayesian scale-mixture of skew-normal model

open access: yesEnvironmental Research Letters, 2023
The timeliness of monitoring is essential to algal bloom management. However, acquiring algal bio-indicators can be time-consuming and laborious, and bloom biomass data often contain a large proportion of extreme values limiting the predictive models ...

Snow algal blooms in Antarctic King George Island in 2017–2022 and their future trend based on CMIP6 projection

open access: yesAdvances in Climate Change Research, 2023
Snow algal blooms have a remarkable climatic or environmental effect through influencing the snow–albedo feedback, accelerating the melting of surface snow, and amplifying global warming.

Development of Algal Bloom Removal System Using Unmanned Aerial Vehicle and Surface Vehicle

open access: yesIEEE Access, 2017
Recently, owing to changes in weather conditions, cyanobacterial blooms, also known as harmful algal blooms (HABs), have caused serious damage to the ecosystems of rivers and lakes by producing cyanotoxins.

Comparative genome and transcriptome analysis of diatom, Skeletonema costatum, reveals evolution of genes for harmful algal bloom

open access: yesBMC Genomics, 2018
Background Diatoms play a great role in carbon fixation with about 20% of the whole fixation in the world. However, harmful algal bloom as known as red tide is a major problem in environment and fishery industry.

Understanding shifts in estuarine fish communities following disturbances using an ensemble modeling framework

open access: yesEcological Indicators, 2021
Ecological disturbances may result in mortality events that alter biotic communities and ecosystems. In many coastal zones disturbances are increasing, including algal blooms and fish kills. These two disturbances are often related, with blooms releasing
