Massive blooms of the harmful alga Cochlodinium polykrikoides Margalef occurred in the lower Chesapeake Bay and its tributaries during the summers of 2007 and 2008. The Lafayette and Elizabeth Rivers appeared to act as initiation grounds for these blooms during both years. However, in 2008 there were also localized sites of initiation and growth of populations within the mesohaline portion of the James River. Bloom initiation appeared to be correlated with intense, highly localized rainfall…

Controls on the initiation and development of blooms of the dinoflagellate Cochlodinium polykrikoides Margalef in lower Chesapeake Bay and its tributaries
TLDR
Daily sampling of nutrient concentrations and phytoplankton abundance at a fixed station was combined to determine physical and chemical controls on bloom formation and enhanced underway water quality monitoring (DATAFLOW) during periods when blooms are known to occur.
Controls on the Formation of Algal Blooms in the Lower Chesapeake Bay and Its Tributaries

Developing a 3D mechanistic model for examining factors contributing to harmful blooms of Margalefidinium polykrikoides in a temperate estuary.
TLDR
Model results suggest that while many factors contribute to the initiation process, temperature, physical transport processes, and cyst germination are the three dominant factors controlling the interannual variability in the timing of bloom initiation.
Blooms of Dinoflagellate Mixotrophs in a Lower Chesapeake Bay Tributary: Carbon and Nitrogen Uptake over Diurnal, Seasonal, and Interannual Timescales
A multi-year study was conducted in the eutrophic Lafayette River, a sub-tributary of the lower Chesapeake Bay during which uptake of inorganic and organic nitrogen (N) and C compounds was measured…
Differential Mortality of North Atlantic Bivalve Molluscs During Harmful Algal Blooms Caused by the Dinoflagellate, Cochlodinium (a.k.a. Margalefidinium) polykrikoides
TLDR
Results suggest that blooms of C. polykrikoides pose significant age- and species-specific threats to native and cultured bivalve shellfish and that shellfish deployed in surface waters are at greater risk during blooms than those deployed at depth.
Mesoscale and Nutrient Conditions Associated with the Massive 2008 Cochlodinium polykrikoides Bloom in the Sea of Oman/Arabian Gulf
TLDR
Findings suggest that mesoscale features were important in bloom dynamics more regionally, but locally the bloom was sustained by nutrient enrichment supplemented by its mixotrophic capabilities.
The Development and Proliferation of Summer Algal Blooms in the Oligo/Poly-Haline Portion of the Chesapeake Bay - Observational and Numerical Modeling Studies
Back River is located along the western shoreline of the upper Chesapeake Bay and is about 8 miles in length and 2-3 meters in average depth. Each summer, algal blooms with chlorophyll-a…
Understanding controls on Margalefidinium polykrikoides blooms in the lower Chesapeake Bay.
TLDR
A time-dependent model of Margalefidinium polykrikoides, a mixotrophic dinoflagellate, cell growth was implemented to assess controls on blooms in the Lafayette River, a shallow, tidal sub-tributary of the lower Chesapeake Bay, and suggested that blooms of M. polykRIkoides are fortified and maintained by substantial heterotrophic nutritional inputs.
Phytoplankton and nutrient dynamics in a tidally dominated eutrophic estuary: daily variability and controls on bloom formation
TLDR
To better understand nutrient dynamics and factors that promote the initiation of algal blooms, the Lafayette River was sampled daily for a period of 54 d in the fall of 2005 and all measured forms of nitrogen were positively correlated with dinoflagellate abundance with a lag time of 3 to 5 d, suggesting a triggering effect.

Understanding Causes and Impacts of the Dinoflagellate, Cochlodinium polykrikoides, Blooms in the Chesapeake Bay
TLDR
Bioassays determined that C. polykrikoides exerted a lethal affect on juvenile fish and shellfish, causing 100% mortality of juvenile fish (Cyprinodon variegates) in less than 24 h and 20% mortality in juvenile American oysters within 72 h.
Impacts and potential effects due to Prorocentrum minimum blooms in Chesapeake Bay
Abstract The dinoflagellate Prorocentrum minimum ( P. minimum ) can be found in all seasons and over a broad range of habitat conditions in the Chesapeake Bay and its tributaries. Blooms (>3000 cells…
Excessive nutrients select for dinoflagellates in the stratified Patapsco River estuary: Margalef reigns
TLDR
From these traits, the dinoflagellate-dominated mesohaline Patapsco River estuary and the tidal-fresh cyano- bacteria bloom areas of the upper Potomac River appear to be analogous, with salinity defining composition of the phytoplankton.
Diurnal vertical migration of a harmful dinoflagellate, Cochlodinium polykrikoides (Dinophyceae), during a red tide in coastal waters of Namhae Island, Korea
TLDR
The results suggest that the variation in the frequency of each type of chain could be an ecological strategy through which the population can produce sufficient propulsion while it has long chains to migrate upward from the sediments before sunrise, whereas the short chains, with a high area: volume ratio, may be more efficient in energy capture after arrival in the surface layers.

First record of a fish-killing Gymnodinium sp. bloom in Kuwait Bay, Arabian Sea: chronology and potential causes
TLDR
The occurrence of this toxic algal bloom event, the first within the Arabian Sea, highlights the need for monitoring and research programs in the Saudi Arabian Sea and Kuwait Bay that focus on nutrients and eutrophication, in addition to oil related pollution issues.
Deleterious consequences of a red tide dinoflagellate Cochlodinium polykrikoides for the calanoid copepod Acartia tonsa
TLDR
The dinoflagellate Cochlodinium polykrikoides Margalef has formed dense blooms and caused severe fish kills on a global scale in recent decades and its deleterious consequences may lead to A. tonsa population collapses during C. polykRIkoides blooms.
Allelopathic effects of Cochlodinium polykrikoides isolates and blooms from the estuaries of Long Island, New York, on co-occurring phytoplankton.
TLDR
The rapid and strong allelopathic effects exhibited by C. polykrikoides suggest allelopathy may facilitate blooms by eliminating com- peting species and these results are consistent with bioassays of fish and shellfish larvae with C.polykriKOides, suggesting that its toxicity to fish andShellfish larvae and its allelopathies are caused by the same agents.
A review of phytoplankton composition within Chesapeake Bay and its tidal estuaries
TLDR
Comparison with collections made ∼8 decades ago within Chesapeake Bay indicated several of the same dominant flora remain dominant today; however, their cell concentrations are now significantly greater along with an increased diversity of species compared with these earlier studies.
