First Light Demonstration of Red Solar Induced Fluorescence for Harmful Algal Bloom Monitoring

Geophysical Research Letters, Volume 50, Issue 13, 16 July 2023., 2023
Abstract The risks harmful algal blooms (HAB) pose to aquatic ecosystems, public health, and coastal economies necessitate supplementation of current observation strategies. Herein, we explore the use of red solar induced fluorescence (SIF) from the TROPOspheric Monitoring Instrument (TROPOMI), a remote sensing measurement retrievable in variable cloud

Potential Threats Posed by New or Emerging Marine Biotoxins in UK Waters and Examination of Detection Methodology Used in Their Control: Brevetoxins

Marine Drugs, 2015
Regular occurrence of brevetoxin-producing toxic phytoplankton in commercial shellfishery areas poses a significant risk to shellfish consumer health. Brevetoxins and their causative toxic phytoplankton are more limited in their global distribution than

First Case of Brevetoxicosis Linked to Rough-Toothed Dolphin (Steno bredanensis) Mass-Mortality Event in Eastern Central Atlantic Ocean: A Climate Change Effect?

Frontiers in Marine Science, 2022
Harmful algal blooms (HABs) have been increasingly recorded over the last decades and much work has linked these events to multiple oceanographic and climate disturbances.

Spectroscopic ellipsometry methods for brevetoxin detection

Talanta, 2022
The spectroscopic ellipsometry (SE), and attenuated internal reflection spectroscopic ellipsometry (TIRE) are promising methods in label-free biosensing applications. An ellipsometer running under surface plasmon resonance (SPR) conditions has unique advantages over other SPR-based methods in terms of sensitivity and real-time/label-free measurement ...

Synthesis, Modeling, and Biological Evaluation of Analogues of the Semisynthetic Brevetoxin Antagonist β‐Naphthoyl‐Brevetoxin [PDF]

ChemBioChem, 2007
AbstractBrevetoxins are neurotoxic compounds produced by the dinoflagellate Karenia brevis. Extensive blooms induce neurotoxic shellfish poisoning (NSP) and asthma‐like symptoms in humans. β‐naphthoyl‐brevetoxin, the first semisynthetic brevetoxin antagonist, has been defined as the lead compound in the investigation of the mechanisms of ...

Further Insights into Brevetoxin Metabolism by de Novo Radiolabeling

Toxins, 2014
The toxic dinoflagellate Karenia brevis, responsible for early harmful algal blooms in the Gulf of Mexico, produces many secondary metabolites, including potent neurotoxins called brevetoxins (PbTx).

Determination of brevetoxin in recent marine sediments [PDF]

Chemosphere, 2008
Harmful algal blooms (HAB) of Karenia brevis (K. brevis) produce a suite of lipid soluble polyether brevetoxins, known to cause environmental, health and economic ill effects. There is evidence that K. brevis has increased in abundance over the past 50 years, but the dataset is incomplete.

Structure Activity Relationship of Brevenal Hydrazide Derivatives

Marine Drugs, 2014
Brevenal is a ladder frame polyether produced by the dinoflagellate Karenia brevis. This organism is also responsible for the production of the neurotoxic compounds known as brevetoxins. Ingestion or inhalation of the brevetoxins leads to adverse effects

Lessening the Hazards of Florida Red Tides: A Common Sense Approach

Frontiers in Marine Science, 2020
In the Gulf of Mexico, especially along the southwest Florida coast, blooms of the dinoflagellate Karenia brevis are a coastal natural hazard. The organism produces a potent class of toxins, known as brevetoxins, which are released following cell lysis ...
