Phytoplankton blooms

This study highlights the usefulness of functional groups in the study of seasonal changes in phytoplankton dynamics. Functional groups are applied for the first time at Tuyen Lam Reservoir and can be used to predict early-stage cyanobacterial blooms in future studies.

The Gulf of Thailand is a semi-closed Gulf on the west and southwest side of the Indochina Penisula and experiences reversal monsoon. The object of the present study is to investigate monthly and spatial distributions of the phytoplankton in the Gulf of Thailand during whole El Nino year 2002 by using remote-sensing measurements of chlorophyll-a (Chl-a) and surface wind vectors.

The main objective of this study was to confirm and estimate the algal inhibiting effects of the ethanol and ethyl acetate E. fortunei extracts at concentrations of 500 mg.L- in some natural water samples collected from Hoan Kiem and Lang Lakes. The results of this work may be useful for controlling the toxic cyanobacterium bloom in natural aquatic ecosystem.

Planktonic diatoms produce resting stages that survive in the sediment and allow species persistence over periods in which vegetative growth does not occur. Sediments from coastal estuary in the Mokpo Harbour, Korea were took and investigated. Diatom germination tests from sediment were carried out in laboratory. Diatom cells were identified by microscope based on standard method.

To determine the occurrence of dominant phytoplanktonic species causing red tides along the eastern Black Sea (Trabzon) coast of Turkey, multiple samples were collected periodically between 1991 and 2001. Red tide events were observed only during the periods between February and July. Six phytoplanktonic species causing 5 red tide events detected were Diplopsalis lenticula, Euglena acusformis, Eutreptia lanowii, Pyramimonas orientalis, Scrippsiella trochoidea, and Gymnodinium sanguineum.

The level of surface water quality protection is variable around the world in large part due to the relative effectiveness of environmental regulation and the degree to which science influences the regulatory process. In the United States, at the federal level, the Total Maximum Daily Load (TMDL) has been an effective policy and water quality management tool for dealing with both point source and non-point source pollution.
