Suneel, V.; Saha, M.; Rathore, C.; Sequeira, J.; Mohan, P.M.N.; Ray, D.; Veerasingam, S.; Rao, V.T.; Vethamony, P. (2019)In June 2016, a cruise vessel was grounded in the Mormugao Port, resulting in unnoticed oil spill. The surface water and sediment samples were collected from the vicinity of the ship, and also an oil sample from the ship ... -
Characteristics, seasonal distribution and surface degradation features of microplastic pellets along the Goa coast, India
Veerasingam, S.; Saha, M.; Suneel, V.; Vethamony, P.; Rodrigues, A.C.; Bhattacharyya, S.; Naik, B.G. (Elsevier, 2016)Microplastic pellets (MPPs) are ubiquitous contaminants, recognised as a serious threat to the biota in coastal, estuarine and marine environment. The distribution, abundance, weathering and chemical characteristics of ... -
Characterization of 2004 Indian Ocean tsunami induced deposits along the Chennai coast using magnetic and geochemical techniques
Veerasingam, S.; Venkatachalapathy, R. (CSIR-NISCAIR, 2014)Present study is the applicability of rock magnetic techniques, coupled with geochemical (SiO<sub>2</sub>, Al<sub>2</sub> O<sub>3</sub> , Fe<sub>2</sub>O<sub>3</sub>, CaO, MgO, K<sub>2</sub>O, P<sub>2</sub>O<sub>5</sub>, ... -
Depositional record of trace metals and degree of contamination in core sediments from the Mandovi estuarine mangrove ecosystem, west coast of India
Veerasingam, S.; Vethamony, P.; ManiMurali, R.; Fernandes, B. (Elsevier, 2015)The concentrations of seven trace metals (Fe, Mn, Cu, Cr, Co, Pb and Zn) in three sediment cores were analysed to assess the depositional trends of metals and their contamination level in the Mandovi estuary, west coast ... -
Distribution of clay minerals in marine sediments off Chennai, Bay of Bengal, India: Indicators of sediment sources and transport processes .
Veerasingam, S.; Venkatachalapathy, R.; Ramkumar, T. (Elsevier, 2014)Clay mineralogy, texture size and statistical analyses were carried out on surface sediments from the continental shelf of Chennai, Bay of Bengal, India. The purpose of this study is to characterize the clay mineral ... -
Estimation of carbonate concentration and characterization of marine sediments by Fourier transform infrared spectroscopy.
Veerasingam, S.; Venkatachalapathy, R. (Elsevier, 2014)Fourier Transform Infrared Spectroscopy (FTIR) is a well established method for the characterization of mineralogical and geochemical properties of marine sediments. Understanding the biogeochemical changes in marine ... -
Historical environmental pollution trend and ecological risk assessment of trace metals in marine sediments off Adyar estuary, Bay of Bengal, India.
Veerasingam, S.; Venkatachalapathy, R.; Ramkumar, T. (Springer, 2014)Geochemical, mineralogical and textural analyses were carried out in core sediments off Adyar estuary, Bay of Bengal, India to record the contamination trend from urban and industrial activities during the historical past. ... -
Identification and characterization of tsunami deposits off southeast coast of India from the 2004 Indian Ocean tsunami: Rock magnetic and geochemical approach.
Veerasingam, S.; Venkatachalapathy, R.; Basavaiah, N.; Ramkumar, T.; Venkatramanan, S.; Deenadayalan, K. (Indian Academy of Sciences, 2014)The December 2004 Indian Ocean Tsunami (IOT) had a major impact on the geomorphology and sedimentology of the east coast of India. Estimation of the magnitude of the tsunami from its deposits is a challenging topic to be ... -
Influence of 2015 flood on the distribution and occurrence of microplastic pellets along the Chennai coast, India
