In some cases, the attempt to cleanup can be made using physical and chemical methods. However, for the Antarctic environments this is not so simple. Displacement of the machinery necessary for the application of physical methods would be very expensive whereas the application of chemical methods would be dangerous considering the risks of additional environmental impacts. Bioremediation techniques are relatively more costeffective and benign. This technique is based on the ability of some microorganisms (especially some bacteria) to use the petroleum hydrocarbons as energy source. Considering the low-risk, the best cost-effective choice to be applied in oil-contaminated sites, presenting high rates of hydrocarbon degradation, is the monitored natural attenuation. However, in some cases, environmental factors can cause the recalcitrance of the pollutant. The more frequent cause of recalcitrance is the depletion of nutrients (especially N and P) due to input of large quantities of carbon sources (petroleum hydrocarbons). An alternative to overcome this problem is the addition of fertilizers (e.g. N-P-K, MAP, DAP). This technique is known as biostimulation. However, some precautions must be taken. For the biostimulation the most important aspect is to avoid the excess of fertilizer, which could cause side effects like eutrophication. Temperature is a critical factor for bioremediation success. In Antarctic soils, low temperatures can decrease the rate of biodegradation even when nutrients are available in satisfactory concentrations. An alternative to overcome this difficulty is to increase the number of cells of a consortium of degraders in artificial mediums under conditions of optimum growth before the introduction in nutrient-amended polluted soils. This technique is known as bioaugmentation. Theoretically, bioaugmentation is a more promising technique than biostimulation. However, the effectiveness of bioaugmentation is variable due to the low rates of survival and degrading capability of introduced microorganisms. Furthermore, in Antarctic soils the implementation of this technique is not feasible since the introduction of alien species should be avoided. An alternative to overcome these difficulties is to introduce indigenous microorganisms capable of degrading oil to the contaminated site. The purpose of the work that is being implemented is to test different doses of fertilizer in microcosms and mesocosms and to isolate and cultivate microorganisms 3","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133894933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radio signals were registered by an Automatic Listening Station between December 2009 and February 2010. Females attend more often the nest than males (binominal test, Chi2 = 799.3; P < 0.001), although the mean number of days each gender attended the nest was not different (F = 0.01; P = 0.92).

The samples were taken near the Ozone and Meteorology Modules, weather conditions, such as direction and intensity of the wind, being annotated. For measurements of the concentration of GHG, a collection system that used a diaphragm pump, with samples of air being stored in stainless steel cylinders, was used. Concentrations of gases of interest in the samples collected were determined by the ozone gas chromatography laboratory, in São José dos Campos/SP. Furthermore, a continuous infrared monitor (model LI-820 Licor Gas Analyzer) was installed in the Ozone Module. There was great stability of the concentration values obtained by liquor, in that the average for these records were 378.8 ± 2.0 ppm (parts per million by volume), very close to that reported at NOAA’s (National Oceanic and Atmospheric Administration) polar station (385 ppm). Analyses of nitrous oxide (N2O) collected in the cylinders in the months of January to March 2010 resulted in an average of 334.7 ± 2.0 ppb (parts per billion by volume), very close to that reported by NOAA as a global average (323 ppb), however it was noted that this value was virtually constant in all samples, which reflected in low standard deviation, revealing an offset in our pattern to be given in subsequent samples. Samples collected in cylinders in the same period and analyzed for methane showed an average 1,791.4 ± 38.0 ppb. This value is higher than expected for the region (1,750 ppbv). However there was a wide variability in the samples (represented by the standard deviation) reflecting local sample point, mainly in the samples collected near the station. CO data did not pass in the validation tests, mainly due to their long storage time. As the CO is reactive and can undergo alteration inside the cylinder through other compounds, the storage time led to reactions inside the cylinders, causing the invalidation of the samples for this gas.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123782950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
