Image processing for smart browsing of ocean colour data products and subsequent incorporation into a multi-modal sensing framework [PDF]

open access: yes, 2010
Ocean colour is defined as the water hue due to the presence of tiny plants containing the pigment chlorophyll, sediments and coloured dissolved organic material and so water colour can provide valuable information on coastal ecosystems.

Detection of polyketide synthetase gene expression in Karenia brevis

open access: yes, 2008
The present invention concerns an assay for the detection of polyketide synthetase (PKS) mRNA from the red tide dinoflagellate Karenia brevis. Another aspect of the invention concerns NASBA primers and a molecular beacon that enable detection of mRNA of ...

Absolute Configuration of Brevisamide and Brevisin: Confirmation of a Universal Biosynthetic Process for Karenia brevis Polyethers

open access: yes, 2016
The discovery of brevisin, the first example of an “interrupted” polycyclic ether, obtained from the dinoflagellate Karenia brevis, posed some important questions regarding the mechanism of the cyclization process.

Progress in Understanding Algal Bloom-Mediated Fish Kills: The Role of Superoxide Radicals, Phycotoxins and Fatty Acids.

open access: yesPLoS ONE, 2015
Quantification of the role of reactive oxygen species, phycotoxins and fatty acids in fish toxicity by harmful marine microalgae remains inconclusive. An in vitro fish gill (from rainbow trout Oncorhynchus mykiss) assay was used to simultaneously assess ...

Characterization and isolation of a rotifer-deterrent compound in the red tide dinoflagellate Karenia brevis

open access: yes, 2006
Spontaneous phytoplankton blooms cause extensive damage to aquatic ecosystems all over the world. Red Tide, a type of bloom, causes extensive damage in the Gulf of Mexico every year.

Responses of sympatric Karenia brevis, Prorocentrum minimum, and Heterosigma akashiwo to the exposure of crude oil

open access: yes, 2014
Impacts of the Deepwater Horizon oil spill on phytoplankton, particularly, the tolerability and changes to the toxin profiles of harmful toxic algal species remain unknown.

Environmental and Behavioral Influences on Karenia Brevis' Nitrate Uptake

open access: yes, 2005
A near-bottom population of Karenia brevis, observed in a 22 m water column on the West Florida Shelf may use sediments as a nutrient source in oligotrophic environments.

The costs of respiratory illnesses arising from Florida gulf coast Karenia brevis blooms

open access: yes, 2009
BACKGROUND: Algal blooms of Karenia brevis, a harmful marine algae, occur almost annually off the west coast of Florida. At high concentrations, K. brevis blooms can cause harm through the release of potent toxins, known as brevetoxins, to the atmosphere.
