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… 
Phytoplankton blooms in estuarine and coastal waters: Seasonal patterns and key species
The meta-analysis of phytoplankton monitoring data shows that these 86 estuarine-coastal sites function as diatom-producingsystems, the timing of that production varies widely, and that bloom frequency is not associated with environmental factors measured in monitoring programs.
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.
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.
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
Eutrophication signals in the sedimentary record of dinoflagellate cysts in coastal waters
Abstract A brief review is presented of the current status of eutrophication signals from the sedimentary records of dinoflagellate cysts in coastal waters, particularly of NW Europe. There is a
Characterizing algal blooms in a shallow & a deep channel
Abstract The outbreaks of algal blooms occur in both shallow and deep-water bodies with varied frequencies in different seasons. To investigate the occurrences of algal blooms in these two different
First record of red macroalgae bloom in Southern Atlantic Brazil
The objective of this study was to characterize and quantify the photosynthetic floating organisms contributing to the forming bloom of red algae on the beach of Garopaba, Santa Catarina State, Brazil, and to reinforce the necessity of coastal integrative management initiatives.


Frequency, composition, and causes of summer phytoplankton blooms in a shallow coastal ecosystem, the Kattegat
We propose a new operational definition for summer phytoplankton blooms based on station-specific chlorophyll a distributions. This definition has been applied to a large monitoring data set from the
Nuisance phytoplankton blooms in coastal, estuarine, and inland waters1
Multiple interacting physical, chemical, and biotic factors, in proper combination, lead to the development and persistence of nuisance algal blooms. Upon examining combinations of environmental
Seasonality of Coastal Phytoplankton in the Baltic Sea: Influence of Salinity and Eutrophication
Abstract In this study long-term (1984–2001) phytoplankton and physico-chemical monitoring data representing different salinity regimes of the Baltic Sea were compiled from HELCOM, national and
Development and fate of Eutreptiella gymnastica bloom in nutrient-enriched enclosures in the coastal Baltic Sea
Response of the phytoplankton community to bottom-up (nutrients, organic carbon source) and top-down (fish) manipulations, both singly and together, were studied daily during a 3 week period in July
Coastal eutrophication and harmful algal blooms : Importance of atmospheric deposition and groundwater as new nitrogen and other nutrient sources
Nitrogen-limited csluaries, shallow coastal waters, and continental shelf ivatcrs cover only 15% of the world’s ocean area, but account for nearly half the global oceanic primary production. This

ABSTRACT Empirical relationships were developed between algal bloom frequencies and total phosphorus concentrations for three distinct regions of Lake Okeechobee, and hypotheses were derived to
Harmful algal blooms: Their ecophysiology and general relevance to phytoplankton blooms in the sea
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.
Summer Algal Blooms in a Coastal Ecosystem: the Role of Atmospheric Deposition Versus Entrainment Fluxes
Abstract The nitrogen inputs from atmospheric deposition and bottom water entrainment to the surface layer were modelled in the summer period (May–September) over a 11-year period (1989–1999) and
