Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Integration of Data for Nowcasting of Harmful Algal Blooms [PDF]

Proceedings of OceanObs'09: Sustained Ocean Observations and Information for Society, 2010
Harmful algal blooms (HABs) are a significant and potentially expanding problem around the world. Resource management and public health protection require sufficient information to reduce the impacts of HABs by response strategies and through warnings and advisories.

Harmful Algal Blooms: Physiology, Behavior, Population Dynamics and Global Impacts- A Review

Sultan Qaboos University Journal for Science, 2005
Harmful, toxic algae are now considered as one of the important players in the newly emerging environmental risk factors. The apparent global increase in harmful algal blooms (HABs) is becoming a serious problem in both aquaculture and fisheries ...

External costs of harmful algal blooms using hedonic valuation: The impact of karenia brevis on Southwest Florida

Environmental and Sustainability Indicators, 2020
We use a hedonic valuation method to measure the costs of harmful algal blooms to properties in Southwest Florida. Persistent blooms of “red tide” have lasted for over months at a time and can render the appeal of the Gulf Coast useless, usually a ...

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...
