Highly Resolved Surface Phytoplankton Community Composition Along the British Columbia Coast, Derived From In Situ Hyperspectral Radiometry

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Quantitative measurements of phytoplankton community composition (PCC) are essential for understanding fisheries production, ocean nutrient cycling, and the export of particulate carbon to the ocean interior. However, these measurements are constrained in dynamic coastal waters due to the spatial‐temporal constraints of in situ sampling ...

Impact of nutritional history, prey quality, and quantity on grazing and photophysiological responses in the mixoplanktonic dinoflagellate Karenia brevis

Limnology and Oceanography, Volume 70, Issue 9, Page 2603-2617, September 2025.
Abstract The mixotrophic toxic dinoflagellate Karenia brevis forms red tides almost annually along Florida's Gulf coast. We hypothesize that the nutritional status and abundance of its prey, the picocyanobacterium Synechococcus, will affect its feeding rates and growth responses, with implications for bloom dynamics.

A severe red tide (Tampa Bay, 2005) causes an anomalous decrease in biological sound [PDF]

Royal Society Open Science, 2015
Although harmful algal blooms (HABs) are known to cause morbidity and mortality in marine organisms, their sublethal effects are poorly understood. The purpose of this study was to compare ambient noise levels during a severe HAB event in Tampa Bay ...

An ecological framework for microbial metabolites in the ocean ecosystem

Limnology and Oceanography Letters, Volume 10, Issue 5, Page 636-659, September 2025.
Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,

Effects of in vitro Brevetoxin Exposure on Apoptosis and Cellular Metabolism in a Leukemic T Cell Line (Jurkat)

Marine Drugs, 2008
Harmful algal blooms (HABs) of the toxic dinoflagellate, Karenia brevis, produce red tide toxins, or brevetoxins. Significant health effects associated with red tide toxin exposure have been reported in sea life and in humans, with brevetoxins documented

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 ...

Long-term increase in Karenia brevis abundance along the Southwest Florida Coast [PDF]

Harmful Algae, 2007
Data collected along the southwest coast of Florida between Tampa Bay and Sanibel Island on the abundance of the toxic dinoflagellate Karenia brevis from 1954 to 2002 were examined for spatial and temporal patterns. K. brevis was found to be approximately 20-fold more abundant within 5 km of the shoreline than 20-30 km offshore. Overall, K.
