A study of cyanobacterial bloom monitoring using unmanned aerial vehicles, spectral indices, and image processing techniques

open access: yesHeliyon, 2023
Last 5 years, the deterioration of water quality caused by algal bloom has emerged as a serious issue in Korea. The method of on-site water sampling to check algal bloom and cyanobacteria is problematic by only partially measuring the site and not fully ...

The genus Sphaerocavum and the dominance of S. brasiliense and Microcystis wesenbergii (Microcystaceae, Cyanophyceae) in the algae bloom of Huacachina lagoon, Peru

open access: yesRevista Peruana de Biología, 2016
The present work registers for the first time the cyanobacteria Sphaerocavum brasiliense Azevedo y Sant’Anna and Microcystis wesenbergii (Komárek) Komárek in Kondrateva (Microcystaceae, Cyanophyceae) in an algal bloom on Huacachina lagoon (Ica ...

An Integrative Remote Sensing Application of Stacked Autoencoder for Atmospheric Correction and Cyanobacteria Estimation Using Hyperspectral Imagery [PDF]

open access: yes, 2020
Hyperspectral image sensing can be used to effectively detect the distribution of harmful cyanobacteria. To accomplish this, physical- and/or model-based simulations have been conducted to perform an atmospheric correction (AC) and an estimation of ...

Molecular detection of hepatotoxic cyanobacteria in inland water bodies of the Marmara Region, Turkey

open access: yesAdvances in Oceanography and Limnology, 2017
Blooms of cyanobacteria are an increasingly frequent phenomenon in freshwater ecosystems worldwide as a result of eutrophication. Many species can produce hepatotoxins that cause severe health hazards to humans.

Development and field assessment of a quantitative PCR for the detection and enumeration of the noxious bloom-former Anabaena planktonica [PDF]

open access: yes, 2007
Anabaena planktonica is a harmful, bloom-forming freshwater cyanobacterium, which has arrived recently in New Zealand. In the short time since its incursion (

Hypoxia Sustains Cyanobacteria Blooms in the Baltic Sea

open access: yesEnvironmental Science & Technology, 2014
Nutrient over-enrichment is one of the classic triggering mechanisms for the occurrence of cyanobacteria blooms in aquatic ecosystems. In the Baltic Sea, cyanobacteria regularly occur in the late summer months and form nuisance accumulations in surface waters and their abundance has intensified significantly in the past 50 years attributed to human ...

Harmful Freshwater Algal Blooms, With an Emphasis on Cyanobacteria [PDF]

open access: yesThe Scientific World JOURNAL, 2001
Suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Phytoplankton productivity is reliant on adequate nutrient supplies; however, increasing rates of nutrient supply, much of it manmade, fuels accelerating primary production or eutrophication.

High capacity for a dietary specialist consumer population to cope with increasing cyanobacterial blooms

open access: yesScientific Reports, 2022
We present a common-garden experiment to examine the amphipod Monoporeia affinis, a key deposit-feeder in the Baltic Sea, a low diversity system offering a good model for studying local adaptations.
