Cultivation and culture-independent techniques were used to describe the geothermal ecosystem of the Blue Lagoon in Iceland. The lagoon contains both seawater and freshwater of geothermal origin and is extremely high in silica content. Water samples were collected repeatedly in summer and autumn in 2003 and 2005 and in winter 2006 were analyzed for species composition. The study revealed the ty...

Recovery of phosphate (PO4-P) as struvite (MgNH4PO4·6H2O) from dairy lagoon wastewater (DW) limits contamination surface water arising application DW to crop fields. Magnesium (Mg) addition during PO4-P recovery is used promote precipitation and suppress formation undesired mineral products. A pilot-scale aerated fluidized-bed reactor was treat for recovery. The effect Mg concentration (0–20 mM...

Our research goal is to monitor the water pollution and aquatic plants in the coastal lagoon environments using satellite data. This time, our past activities concerning some satellite study project and the preliminary result of ALOS/AVNIR-2 analysis in coastal lagoon such as Lakes Shinji and Nakaumi are introduced.

We studied the population sizes and substrate incorporation patterns of three phylogenetic groups of Betaproteobacteria in a coastal subtropical lagoon that is characterized by a sharp transition from humic freshwater to turbid brackish water. Various cellular processes were addressed by short-term incubations with four radiolabelled compounds and microautoradiographic assessment of substrate i...

The Manzala Lagoon in Egypt's Nile ' »elta has become a sediment sink of reduced area and depth, with increased contaminant levels. Loss of much-needed fresh to brackish water reserves and decreased fish catches have serious ramifications. Herein, maps of temporal and regional sediment distributions in Manzala incorporate petrological and statistical analyses of 200 surficial and short core sam...

Historical descriptions of the Clipperton lagoon appear to converge on the fact that it became isolated from the surrounding ocean around 1858. Since then, because of the high precipitation rate which largely exceeds evaporation in this region of the eastern tropical Pacific, a brackish lens has formed on top of the saline oceanic waters. In 1980, literature data show that the thickness of this...

The Oder estuary, especially the large, shallow Szczecin (Oder) Lagoon (687 W, average depth 3.8 m) suffers from severe and ongoing eutrophication due to heavy loads, mainly by the Oder river. Poor water quality nowadays is a main obstacle for further touristic development around the lagoon. Long-term nutrient concentrations show a high interannual variability and a decline during recent years....

Testicular histology of mature grass goby (Zosterisessor ophiocephalus) collected in Bizerta lagoon showed several types of histological lesions. A high prevalence of these lesions was detected in stations influenced by discharges of industrial and/or urban activities. These results highlight the reproductive disturbance of gobies from Bizerta lagoon.
