2. Influência de efluentes domésticos e petroquímicos em sedimentos e carapaças de foraminíferos do Canal de São Sebastião, SP / Influence of domestic and petrochemical sewage in tests of foraminifera and sediments of the São Sebastião Channel, SP
O presente estudo teve por objetivo avaliar a influência de esgotos domésticos e petroquímicos, dispostos por via de emissário submarino, nas composições físico-químicas e microbiológicas da coluna dágua e na geoquímica dos sedimentos, bem como investigar uma possível relação entre o meio e a composição química das carapaças do foraminífer

3. NUMERICAL MODELING OF SEWAGE PLUME DISPERSION FOR THE SANTOS OUTFALL / Modelagem numérica da dispersão da pluma do emissário submarino de Santos
Sewage plume dispersion for the Santos outfall was studied using numerical models, coupling hydrodynamic, near field and far field models. Experiments were conducted for the 1979 original outfall design, for the new 2009 outfall configuration and also for a third arrangement suggested here, which duplicates the emissary length comparatively to the original 1

4. Production of biopolymers by Pseudomonas aeruginosa isolated from marine source
Two bacterial strains, Pseudomonas aeruginosa CMG607w and CMG1421 produce commercially important biopolymers. CMG607w isolated from the sediments of Lyari outfall to Arabian Sea synthesize the mcl-polyhydroxyalkanoates from various carbon sources. The production of PHAs was directly proportional to the incubation periods. Other strain CMG1421, a dry soil iso

5. "Estudo hidrogeoquímico, sedimentológico e de foraminíferos em áreas da Baixada Santista, SP, submetidas a disposição oceânica de esgotos" / "Study hydrogeochemical, sedimentological and of foraminifers in regions of the Baixada Santista, SP, submitted to oceanic sewage disposal"
O presente estudo analisou a influência do emissário submarino de esgoto sobre as associações de foraminíferos, regionalmente (macroescala) e localmente (microescala), na Enseada do Guarujá e Baía de Santos. Foram analisadas, em macroescala, 26 amostras coletadas na Enseada do Guarujá e 24 na Baía de Santos. As amostras foram obtidas no inverno de 1

6. Evaluation of fecal sterols and geochemical markers hydrocarbons in sediments from Admiralty Bay, Antartica. / "Avaliação de introdução de esteróis fecais e hidrocarbonetos marcadores geoquímicos em sedimentos da Baía do Almirantado, Península Antártica"
Sewage and oil contribution are the main sources of pollution from the scientific stations to the antarctic marine environment. Sterols and hydrocarbons such as n-alkanes, polyciclic aromatics (PAHs) and linear alkylbenzenes (LABs) were investigated on surface sediments from Admiralty Bay, King George Island, Antarctica, collected during austral summer of 19

7. Distribution of Clostridium perfringens and Fecal Sterols in a Benthic Coastal Marine Environment Influenced by the Sewage Outfall from McMurdo Station, Antarctica†
The spatial distribution, movement, and impact of the untreated wastewater outfall from McMurdo Station, Antarctica, were investigated under early austral summer conditions. The benthic environment was examined to determine the distribution of Clostridium perfringens in sediment cores and the intestinal contents of native invertebrates and fish along a trans

8. Coincident plasmids and antimicrobial resistance in marine bacteria isolated from polluted and unpolluted Atlantic Ocean samples.
Sewage effluent and outfall confluence samples were collected at the Barceloneta Regional Treatment Plant in Barceloneta, Puerto Rico; outfall confluence samples at Ocean City, Md., were also collected. Samples from uncontaminated open ocean areas served as clean-water controls. Bacteria were enriched in marine broth 2216 amended with 1 microgram of one of a

9. Antibiotic Resistance Among Coliform and Fecal Coliform Bacteria Isolated from Sewage, Seawater, and Marine Shellfish
Seawater and shellfish samples collected in the vicinity of a marine sewage outfall were examined for the incidence of antibiotic resistance among coliform and fecal coliform bacteria over a 2-year period. Seventy percent or more of these two groups of bacteria from both sources were resistant to one or more antibiotics. Forty-five percent of the isolates re

10. Correlation of Direct Viable Counts with Heterotrophic Activity for Marine Bacteria
Viable-bacteria counts, heterotrophic activity, and substrate responsiveness of viable bacteria have been used to measure microbial activity. However, the relationship between these parameters is not clear. Thus, the direct viable count (DVC) method was used to analyze seawater samples collected from several different geographical locations. Samples collecte

11. Influence of Seasonal Environmental Variables on the Distribution of Presumptive Fecal Coliforms around an Antarctic Research Station
Factors affecting fecal microorganism survival and distribution in the Antarctic marine environment include solar radiation, water salinity, temperature, sea ice conditions, and fecal input by humans and local wildlife populations. This study assessed the influence of these factors on the distribution of presumptive fecal coliforms around Rothera Point, Adel

12. Coliphage and indigenous phage in Mamala Bay, Oahu, Hawaii.
Public concern over the discharge of primarily treated sewage by two offshore outfalls in Mamala Bay, Oahu, prompted a multidisciplinary study to determine the impact of such activities on the water quality in the bay and at adjacent recreational beaches. As part of this study, we determined the abundance of coliphage as an indicator of fecal pollution along
