Metabarcoding of harmful algal bloom species in sediments from four coastal areas of the southeast China

open access: yesFrontiers in Microbiology, 2022
In the past three decades, harmful algal blooms (HAB) have become more frequent and widespread in southeast Chinese sea areas. Resting stages are regarded as the “seed bank” of algal blooms, and play an important role in initiating HABs. The distribution

Historical Occurrence of Algal Blooms in the Northern Beibu Gulf of China and Implications for Future Trends

open access: yesFrontiers in Microbiology, 2019
Large-scale harmful algal blooms (HABs) occur in the coastal waters of the northern Beibu Gulf, China, and have deleterious effects on the marine ecosystem.

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

Modelling algal densities in harmful algal blooms (HAB) with stochastic dynamics

open access: yesApplied Mathematical Modelling, 2008
The authors select typical HAB (harmful algae blooms) - diatom and dianoflagellate, and propose to add some random terms (excitations) to a known model such that they get the stochastic system \[ \frac{dP_1}{dt}=\varepsilon P_1-a P_1^2-\alpha P_1P_2+\alpha_1 P_1 \xi(t)+\beta_1\eta(t), \] \[ \frac{dP_2}{dt}=\varepsilon P_2-b P_2^2-\beta P_1P_2+\alpha_2 ...

Factors affecting harmful algal bloom occurrence in a river with regulated hydrology

open access: yesJournal of Hydrology: Regional Studies, 2021
Study region: The Geum River Basin, South Korea. Study focus: In-stream structures potentially amplify harmful algal blooms (HABs) by increasing water residence time and deteriorating water quality.

Proposal of an integrated system for forecasting Harmful Algal Blooms (HAB) in Chile

open access: yesLatin American Journal of Aquatic Research, 2018
Harmful Algal Blooms (HAB), are natural phenomena that are produced by the proliferation of phytoplankton potentially harmful to humans and for some ecosystem services ( e.g ., good water quality for use in aquaculture, availability of natural resources). In Chile, HAB events of Pseudo-nitzschia spp.

GlobalHAB: Fostering International Coordination on Harmful Algal Bloom Research in Aquatic Systems

open access: yes, 2018
GlobalHAB, “Global Harmful Algal Blooms,” is a new scientific programme on harmful algal blooms (HABs) cosponsored by the Intergovernmental Oceanographic Commission (IOC) of UNESCO and the Scientific Committee on Oceanic Research (SCOR) that will operate

Introduction to Harmful Algal Blooms (HABs) in Freshwater Systems

open access: yes, 2022
Harmful Algal Blooms (HABs) are detrimental to the ecosystem through their biomass and toxin production. HABs monitoring is complicated by existence of diverse species of algae causing blooms and their varying enabling conditions.

Retrospective analysis of Chlorophyll-a and its correlation with climate and hydrological variations in Mindu Dam, Morogoro, Tanzania

open access: yesHeliyon, 2019
The measurement of Chlorophyll-a in aquatic systems has usually correlated to harmful algae in water bodies. Harmful algal blooms (HABs) are as a result of massive proliferation of blue-green algae (Cyanobacteria).

Interannual and Decadal Changes in Harmful Algal Blooms in the Coastal Waters of Fujian, China

open access: yesToxins, 2022
The temporal and spatial variability of harmful algal blooms (HABs) in coastal waters of Fujian were analyzed at interannual and decadal scales based on recorded HAB events collected from 1956 to 2019.
