Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.

Download or read book Real time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

This book was released on 2015 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) caused by the toxic dinoflagellate Alexandrium fundyense are a recurrent and widespread problem in both coastal and offshore waters of the northeastern United States. A. fundyense produces a suite of potent neurotoxins, collectively known as saxitoxins, that threaten public health with illness called paralytic shellfish poisoning (PSP). The adverse effects of A. fundyense blooms on public health, marine ecosystems, and local economies have focused much attention on defining the factors that determine the abundance and distribution of this toxic dinoflagellate, and also those that characterize toxin movement in marine food webs. PSP toxins can become concentrated in marine consumers through feeding interactions in both benthic and pelagic food webs. Included are bivalves that directly ingest toxic algae through suspension feeding, as well as pelagic consumers such as fish, marine mammals and birds, which accumulate algal toxins through consumption of contaminated prey. Various forms of zooplankton that feed directly upon toxic algae play two pivotal roles in HAB dynamics : (1) zooplankton grazing on harmful algae represents an important loss factor that can influence bloom development and termination and (2) zooplankton provide the first link in moving algal toxins to higher trophic levels in marine food webs. However, the role of zooplankton grazing remains one of the most poorly understood of the biological controls on A. fundyense blooms. This dissertation had two major goals : (1) to further our understanding of and characterize the role of zooplankton grazing as a loss factor in the ecology of A. fundyense blooms, and (2) to elucidate trophic pathways of PSP toxin transfer in marine planktonic food webs by identifying the community of consumers that are toxin vectors. In order to assess the role of zooplankton grazing on net growth rates of natural A. fundyense populations, incubation experiments were conducted on seawater samples during a natural bloom in spring of 2012 within the Nauset Marsh System (NMS) on Cape Cod, Massachusetts. Abundances of both microzooplankton and mesozooplankton grazers were determined in addition to A. fundyense abundances. This study documented net growth rates that were highly variable throughout the bloom. Microzooplankton appeared to exert greater grazing pressure than mesozooplankton. Microzooplankters observed with ingested A. fundyense cells included polychaete larvae, rotifers, tintinnids, and heterotrophic dinoflagellates of the genera Polykrikos and Gymnodinium. This study also highlighted the difficulty in separating the overlapping variability and uncertainties in A. fundyense growth, grazing pressure, germination and encystment even when physical advection minimally impacts the populations. PSP toxin accumulation in the planktonic food web was also examined. During three A. fundyense bloom seasons (2007, 2008, and 2010) the regional A. fundyense bloom in the coastal Gulf of Maine and on Georges Bank was sampled in order to measure PSP toxins in the planktonic food web and identify potential PSP toxin vectors. A fundyense cells and zooplankton were collected by quantitatively pumping seawater from known depths through plankton sieves of various mesh sizes - using half of each sample for toxin analyses and the other half for microscopically counting and identifying A. fundyense and the zooplankton community. Size-fractionated toxin measurements revealed that PSP toxins were widespread throughout all size classes of zooplankton. Diverse assemblages of zooplankton grazers were identified as PSP toxin vectors, including microzooplankton such as tintinnids, heterotrophic dinoflagellates such as Protoperidinium spp., and mesozooplankton grazers such as barnacle nauplii, harpacticoid and calanoid copepods, the marine cladoceran Evadne nordmanni, and hydroids of the genus Clytia. PSP toxin composition in most samples remained fairly consistent during the study, with gonyautoxins (1,2,3, & 4) dominating (>90%) the profile. A fundyense cellular toxin content estimated from field samples was significantly higher in the coastal Gulf of Maine than on Georges Bank, and differences in PSP toxin profiles were also observed - mainly within the composition of the gonyautoxin and carbamate toxin components. This suggests that A. fundyense in the coastal Gulf of Maine and those offshore on Georges Bank are distinct populations.
