InvestigationOpen accessPhrase in the titleRecovered Gases and Bacteria from the Clostridium Genus as Ecological Condition Indicators of Bottom Sediments of the Eastern Donbass Small RiversRoman Gennad'yevich Trubnik, Yuriy Aleksandrovich Fedorov, Ludmila Anatol'yevna NedosekaThe results of determination of methane, total hydrogen sulfide and sulfite reducing clostridia in bottom sediments of small rivers and reservoirs of the Eastern Donbass are presented. The horizontal and vertical distribution of levels of reduced gases in bottom sediments is analyzed. The ecological condition of the bottom sediments was estimated by the clostridia titer and the methane index. The … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 27 Jul 2017 · 7,100 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBacteria of the Clostridium Genus, Methane and Hydrogen Sulfide in Sulfide Mud of the Taman Peninsula ReservoirsYury Aleksandrovich Fedorov, Gar'kusha Dmitry Nikolayevich, Roman Gennad'yevich TrubnikThe features of the distribution of the concentrations of hydrogen sulfide, methane and the number of sulfite-reducing clostridia in the mud of the Bugazsky, Kiziltashsky and Vityazevsky limans and Chembursky lake were studied, and their physiological and chemical conditions and levels of anthropogenic loading were assessed. The tendency of reduction of the content of the studied reduced gases from the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 Aug 2018 · 7,087 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStatistical Analysis of Geothermal Data of an Oil Field, in Parts of Niger Delta, NigeriaEmujakporue Godwin Omokenu, Leonard I. NwosuGeothermal gradient and heat flow were computed from bottom hole temperatures in an oil field in Niger Delta, Nigeria. The statistical analysis of computed geothermal data was carried out. The computed geothermal gradient vary from 17.3±0.14 to 24.33±0.70°C/Km with an average of 22.24±0.57°C/km. The heat flow ranges from 38.06±0.31 to 56.39±2.41 mWm-2 with an average of 50.15±1.25 mWm-2. The computed … …Current Research in Geoscience, Vol. 6, Issue 2 · 26 Sep 2016 · 7,963 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tool Model to Estimate Sediment Yield in Kaw LakeD. Alemayehu, R. Srinivasan, P. DaggupatiKaw Lake is one of the reservoirs built by the Army Corps of Engineers in 1976 for the purpose of flood control, recreation, water supply, navigation and fish and wildlife conservation. The Arkansas River flows from Colorado and Kansas before reaching Oklahoma. As it passes through these states, the water carries various kinds of pollutants such as metals from mine … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 16 Dec 2014 · 8,271 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Assessment of Metals (Pb and Cu) Contamination in Bottom Sediment from South China Sea Coastal Waters, MalaysiaM. C. Ong, B. Y. KamaruzzamanProblem statement: The accumulation of metal contaminants in sediments can pose serious environmental problems to the surrounding areas. Trace metal contamination in sediment could affect the water quality and the bio-assimilation and bioaccumulation of metals in aquatic organisms, resulting in potential long-term implications on human health and ecosystem. Approach: About 154 bottom sediment samples were collected using Smith McIntyre in … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,991 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal Distribution of Organic Carbon in the Surface Sediments of the Terengganu Nearshore Coastal AreaS. Hasrizal, B. Y. Kamaruzzaman, I. Sakri et al.Problem statement: The distribution of organic carbon in the surface sediment is a crucial indicator for current productivity in the ocean especially in the nearshore area. The difference of organic carbon in the surface sediment reflects the influence of current movement on the bottom sediment. Approach: This study was carried out to oversee the difference of organic carbon distribution during … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,473 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordReconstruction of the Depositional Setting of Tortonian Sediments in the Yowi Field, Shallow Offshore Niger Delta, Using Wireline LogsPrince Suka Momta, Minapuye Isaac OdigiWell logs and ditch-cuttings information was used to study the subsurface of the Yowi oilfields, shallow offshore, in the eastern Niger Delta sedimentary basin. The essence of the study was to determine the gross depositional environments of selected and-bodies. Electrofacies trends from gamma ray log and mineral composition of ditch-cutting samples were used to reconstruct the depositional environments in the … …Current Research in Geoscience, Vol. 6, Issue 1 · 8 Feb 2016 · 7,924 accessesView PDF Cite
