The role of nutrient loading and eutrophication in estuarine ecology.
TLDR
Appropriately scaled and parameterized nutrient and hydrologic controls are the only realistic options for controlling phytoplankton blooms, algal toxicity, and other symptoms of eutrophication in estuarine ecosystems.Abstract:
Eutrophication is a process that can be defined as an increase in the rate of supply of organic matter (OM) to an ecosystem. We provide a general overview of the major features driving estuarine eu...read more

Assessing and managing nutrient-enhanced eutrophication in estuarine and coastal waters: Interactive effects of human and climatic perturbations
TL;DR: In this article, the physical and chemical mechanisms controlling algal bloom and hypoxia dynamics were examined using the eutrophic Neuse River Estuary (NRE), North Carolina, USA, as a case study.
Journal ArticleDOI
Nutrients in estuaries--an overview and the potential impacts of climate change.
TL;DR: A more holistic approach is needed to effectively understand, predict and manage the impact of macronutrients on estuaries, and development of high frequency in situ nutrient analysis systems will provide data to improve predictive models that need to incorporate a wider variety of key factors.

Tidal pumping drives nutrient and dissolved organic matter dynamics in a Gulf of Mexico subterranean estuary
Isaac R. Santos,William C. Burnett,Thorsten Dittmar,I. G. N. A. Suryaputra,Jeffrey P. Chanton +4 more
TL;DR: In this article, the authors estimate nutrient production rates using the standard estuarine model and a non-steady-state box model, separate nutrient fluxes associated with fresh and saline submarine groundwater discharge (SGD), and estimate offshore fluxes from radium isotope distributions.
Journal ArticleDOI
Quantity and bioavailability of sediment organic matter as signatures of benthic trophic status
TL;DR: In this article, the protein, carbohydrate and lipid concentrations of sediments from different oceanic and coastal regions and varying water depths were collected to assess benthic marine trophic status.

Evaluating nutrient impacts in urban watersheds: Challenges and research opportunities
Richard O. Carey,George Hochmuth,Christopher J. Martinez,Treavor H. Boyer,Michael D. Dukes,Gurpal S. Toor,John L. Cisar +6 more
TL;DR: This literature review focuses on the prevalence of nitrogen and phosphorus in urban environments and the complex relationships between land use and water quality and identifies pollutant sources that may aid the understanding of harmful algal blooms.

The Ecological Role of Water-Column Microbes in the Sea*
TL;DR: Evidence is presented to suggest that numbers of free bacteria are controlled by nanoplankton~c heterotrophic flagellates which are ubiquitous in the marine water column, thus providing the means for returning some energy from the 'microbial loop' to the conventional planktonic food chain.

Toxic cyanobacteria in water: a guide to their public health consequences, monitoring and management.
Ingrid Chorus,Jamie Bartram +1 more
TL;DR: The state of knowledge regarding the principal considerations in the design of programmes and studies for monitoring water resources and supplies and describes the approaches and procedures used as mentioned in this paper, and the information needed for protecting drinking water sources and recreational water bodies from the health hazards caused by cyanobacteria and their toxins.
Journal ArticleDOI
Coastal marine eutrophication: A definition, social causes, and future concerns
TL;DR: There is a need in the marine research and management communities for a clear operational definition of the term, eutrophication, and the following are proposed: this definition is consistent with historical usage and emphasizes that eUTrophication is a process, not a trophic state.
Journal Article
Life-forms of phytoplankton as survival alternatives in an unstable environment
TL;DR: The best predictor of primary production and of dominant life-forms in phytoplankton is the available externat energy, on which advection and turbulence depend, and this factor overrules more detailed models using light and nutrients as most relevant parameters, and based on laboratory experiments.
