This review addresses both historical and recent investigations into viral contamination of marine waters. With the relatively recent emergence of molecular biology-based assays, a number of investigations have shown that pathogenic viruses are prevalent in marine waters being impacted by sewage. Research has shown that this group of fecal-oral viral pathogens (enteroviruses, hepatitis A viruse...

Gynecologic case report 117 The vast majority of vaginal fungal infections are caused by Candida species, especially Candida albicans1,2. Recently, attention has focused on an unconfirmed increase in vaginal infections caused by C. glabrata3. Most microbiological investigations of large numbers of women with fungal vaginitis have reported infrequent symptomatic vaginitis caused by unusual speci...

1 We compiled from literature annually integrated air-water fluxes of carbon 2 dioxide (CO2) computed from field measurements, in 20 coastal European 3 environments that were gathered into 3 main ecosystems: inner estuaries, upwelling 4 continental shelves and non-upwelling continental shelves. The comparison of annual 5 cycles of the partial pressure of CO2 (pCO2) in 5 contrasting continental ...

This study focuses on Anguilliformes specimens revising which collected during 2006-08 in some Iranian museums. For this study, all museum samples from Iranian coastal waters of the Persian Gulf and Oman Sea were investigated. The results indicated that species diversity in the Iranian waters can be classified into six families of Anguiliformes (Eels and Morays fishes). A total of 11 species ...

The effectiveness of dissolved cadmium (Cd) as a tracer of coastal upwelling is demonstrated by comparing its water column distribution to that of traditional upwelling indicators, in particular phosphate (P) and salinity, as well as equatorward wind forcing at the Oregon coast. Cd and P concentrations in samples collected on board ship on 17–27 August 1995 between 3 and 100 km from the coast o...

After the great Mississippi River flood of 1993, the hypoxic (or low-oxygen) "dead zone" in the Gulf of Mexico more than doubled its size, reaching an all-time high of over 7,700 square miles in July of 1999. Scientists attribute the Gulf of Mexico dead zone largely to nutrient runoff from agriculture in the Mississippi River basin. During the warm months, these nutrients fuel eutrophication, o...

Accurate estimation of diffuse attenuation coefficients in the visible wavelengths Kd(λ) from remotely sensed data is particularly challenging in global oceanic and coastal waters. The objectives of the present study are to evaluate the applicability of a semi-analytical Kd(λ) retrieval model (SAKM) and Jamet's neural network model (JNNM), and then develop a new neural network Kd(λ) retrieval m...

In being at the base of the marine food web, phytoplankton is particularly important for marine ecosystem functioning (e.g., biodiversity). Strong anthropization, over-exploitation of natural resources, and climate change affect the natural amount of phytoplankton and, therefore, represent a continuous threat to the biodiversity in marine waters. In particular, a concerning risks for coastal wa...

Trace metal (Fe, Co, Ni, Cu, Zn, Cd, and Pb) concentrations in zooplankton from the mixed layer were investigated at 8 coastal and 20 offshore stations in the western Bay of Bengal during the summer monsoon of 2003. The ecotoxicological importance of trace metal uptake was apparent within the Bay of Bengal zooplankton. There was a distinct spatial heterogeneity of metals, with highest concentra...
