Research ArticleOpen accessPhrase in the titleSeasonal 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 PDFCite
Research ArticleOpen accessPhrase in the titleStudy of Heavy Metals in the Surface Sediments of the Main Wadis in the Region of Meknes-MoroccoA. Lammini, A. Dehbi, H. Omari, A. AbdallaouiBecause of their growing demographic and industrial expansion, the urban areas of the city of Meknes are likely to disturb the ecological balance of watercourse. In the present work, we had evaluate the degree of sediment’s contamination by heavy metals (Al, Cd, Cu, Fe, Mn, Pb and Zn) in the main wadis of the Meknes region (Boufekrane, Wislane and Toulal) … …Current Research in Geoscience, Vol. 4, Issue 2 · 29 Apr 2015 · 7,109 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSPATIAL AND MULTIVARIATE ANALYSIS OF TRACE ELEMENTS IN THE SURFACE WATER AND DEEP SEDIMENTS OF FRESH WATER AQUATIC ECOSYSTEMKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Kamesh Viswanathan Baskaran et al.The aim of this study was to assess the levels of various trace metals present in water and sediment of fresh water aquatic ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 26 Mar 2014 · 7,597 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Suspended Sediments Concentration in Surface Waters, Using Modis ImagesMobasheri Mohammad RezaRemote sensing from air-borne and space-borne sensors have proved to be a useful method for Suspended Sediment Concentration (SSC) estimation as it provides an instantaneous and synoptic view of suspended sediments that would otherwise be unavailable. The reason for the success of remote sensing in such surveys is the strong positive relationship that exists between SSC and remotely sensed water … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,006 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeochemistry of Sediment in the Major Estuarine Mangrove Forest of Terengganu Region, MalaysiaB.Y. Kamaruzzaman, M.C. Ong, M.S.Noor Azhar et al.Surface sediments collected from seven estuarine mangrove forests of Terengganu region (100 sampling points) were anaylzed for Pb, Cu and Zn using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The average concentration of Pb, Cu and Zn were 10.5±7.12 µg g-1 dry weights, 31.1±16.5 µg g-1 dry weights and 20.8±13.3 µg g-1 dry weights, respectively. The statistical analysis of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,321 accessesView PDFCite

Research ArticleOpen accessIn the abstractFormation of Post-Fire Water Repellent Layers on Nothofagus glauca (Hualo) Forests, After the Historical “Las Máquinas” Wildfire in South-Central ChilePablo A. Garcia-Chevesich, Eduardo Martínez, Alejandro García et al.The Chilean summer of 2017 was the worst wildfire season by far. Hundreds of wildfires burned a total of more than half a million hectares of forested land (native forests and forest plantations). A significant portion of the burned area was occupied by Hualo (Nothofagus glauca (Phil.) Krasser), a native forest species widely distributed in central Chile. Using the water-drop-penetration-time … …American Journal of Environmental Sciences, Vol. 15, Issue 1 · 15 Jan 2019 · 9,388 accessesView PDFCite
