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

Geo 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 ...

Biophysical interactions control the progression of harmful algal blooms in Chesapeake Bay: A novel Lagrangian particle tracking model with mixotrophic growth and vertical migration

Limnology and Oceanography Letters, 2023
Climate change and nutrient pollution contribute to the expanding global footprint of harmful algal blooms. To better predict their spatial distributions and disentangle biophysical controls, a novel Lagrangian particle tracking and biological (LPT‐Bio ...

Multi-omics analysis reveals the molecular response to heat stress in a “red tide” dinoflagellate

Genome Biology, 2023
Background “Red tides” are harmful algal blooms caused by dinoflagellate microalgae that accumulate toxins lethal to other organisms, including humans via consumption of contaminated seafood.

Harmful algal blooms [PDF]

Fact Sheet, 2007
Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. HAB occurrence is affected by a complex set of physical, chemical, biological, hydrological, and meteorological conditions making it difficult to isolate specific causative environmental factors.

Comprehensive analysis of harmful algal blooms in indonesia: from occurrence to impact [PDF]

BIO Web of Conferences
The occurrence and frequency of harmful algal blooms have become a significant problem in Indonesia's coastal waters since 1991. This article aims to thoroughly analyze the diversity of algal species involved in these harmful algal blooms (HABs).

Mediterranean alien harmful algal blooms: origins and impacts [PDF]

Environmental Science and Pollution Research, 2020
AbstractHarmful algal blooms (HABs) are mostly phytoplankton blooms, which have detrimental environmental and socioeconomic impacts. The Mediterranean Sea due to its enclosed nature is of special concern since it has an enormously rich native biodiversity.

Clearing Murky Waters: Red tide video as a mitigation tool

Environmental and Sustainability Indicators
Using video as a public communication tool to increase scientific and health literacy has grown in popularity. This study created and evaluated a YouTube video about red tide in Florida (caused by the microalga Karenia brevis) as part of an environmental

The Role of Cyano-HAB (Cyanobacteria Harmful Algal Blooms) in the One Health Approach to Global Health

Hydrobiology
Harmful algal bloom events occur in salt, brackish, and fresh water. In bodies of water such as oceans and estuaries, diatoms or dinoflagellates form “tides” that produce toxins associated with seafood poisoning, including paralytic shellfish poisoning ...

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

IEEE 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.

HARMFUL ALGAL BLOOMS IN THE MEDITERRANEAN SEA: EFFECTS ON HUMAN HEALTH.

Euromediterranean Biomedical Journal, 2013
A harmful algal bloom (HAB) is defined as a bloom that has deleterious effects on plants, animals or humans. Marine algal toxins are responsible for an array of human illnesses associated with consumption of seafood or exposure to aerosolized toxins ...
