We propose a definition for identification of blooms and use this definition to investigate the underlying mechanisms of summer blooms and their link to nutrient enrichment. Blooms were defined as chlorophyll a observations deviating significantly from a normal seasonal cycle; the frequency and magnitude of these deviating observations characterized bloom frequency and intensity. The definition was applied to a large monitoring data set from five estuaries in Denmark with at least biweekly… 

Physical and Biogeochemical Factors Driving Spatially Heterogeneous Phytoplankton Blooms in Nearshore Waters of Santa Monica Bay, USA

Phytoplankton blooms in nearshore waters are difficult to predict using only biogeochemical factors known to control phytoplankton growth, yet the need to understand these events continues to grow

Feedback Mechanisms Between Cyanobacterial Blooms, Transient Hypoxia, and Benthic Phosphorus Regeneration in Shallow Coastal Environments

We investigated the dissolved oxygen metabolism of the Curonian Lagoon (Baltic Sea) to assess the relative contributions of pelagic and benthic processes to the development of transient hypoxic

Seasonal and annual dynamics of harmful algae and algal toxins revealed through weekly monitoring at two coastal ocean sites off southern California, USA

Investigation of the development of a site-specific bloom definition for identifying emerging domoic acid (DA) events in southern California found the strongest relationship identified was between P. seriata abundances 2 weeks following upwelling events at Newport Beach.

Seasonal diatom cycle in Anegada Bay, El Rincón estuarine system, Argentina

The taxonomic composition and temporal succession of phytoplankton communities in Anegada Bay are comparable with previous studies in Blanca Bay, suggesting relatively uniform phy toplankston seasonality over shoals in the El Rincón estuarine system.

Phytoplankton strategies to exploit nutrients in coastal lagoons with different eutrophication status during re-oligotrophication

We studied a mesotrophic and a hypertrophic Mediterranean coastal lagoon, both of which had been simultaneously subjected to a nutrient input reduction for 9 yr. We compared these 2 lagoons to an

Changes in the Composition and Abundance of Phytoplankton in a Coastal Lagoon of Baja California, México, during 2011

The differences in abundance and composition of phytoplankton groups in the blooms in San Quintin Bay during 2011 were due primarily to seasonal changes in the physical and chemical factors of the seawater and to upwelling events.

HAB flagellates exhibit significant ecophysiological differences when compared to diatoms, including greater biophysical vulnerability to turbulence, greater bloom dependence on water-mass stratification, greater nutritional diversity involving mixotrophic tendencies, greater potential use of allelochemical mechanisms in interspecific competition and antipredation defenses, and unique behaviorial consequences of their motility.
