Identifying the source of tar balls deposited along the beaches of Goa in 2013 and comparing with historical data collected along the west coast of India

Suneel, V.; Vethamony, P.; Naik, B.G.; Krishna, M.S.; Jadhav, L. (Elsevier, 2015)

Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a ...

Inter-annual sea level variability in the southern South China Sea

Soumya, M.; Vethamony, P.; Tkalich, P. (Elsevier, 2015)

The South China Sea (SCS) is the largest marginal sea in the western Pacific Basin. Sea level anomalies (SLAs) in the southern South China Sea (SSCS) are assumed to be governed by various phenomena associated with the ...

Naqvi, S.W.A.; Afzulpurkar, S.; Anil, A.C.; Chakraborty, P.; Dewangan, P.; Desai, D.V.; DeSouza, L.; Kessarkar, P.M.; Khandeparker, L.; Krishna, K.S.; Kurian, S.; Madhan, R.; Mascarenhas, A.A.M.Q.; Mazumdar, A.; Maurya, P.; Murty, V.S.N.; Nath, B.N.; Naik, H.; Navelkar, G.S.; PrasannaKumar, S.; Rao, V.P.; RameshKumar, M.R.; Ravichandran, C.; SanilKumar, V.; Saraswat, R.; Sarma, V.V.S.S.; Shankar, D.; Sharma, R.; Shenoy, D.M.; Suneel, V.; Thakur, N.L.; Unnikrishnan, A.S.; Vethamony, P.; Yatheesh, V. (Current Science Association, 2015)

The present article summarizes the research done at the CSIR–National Institute of Oceanography in 2014 in ocean science, resources and technology. Significant research has been conducted on air–sea interactions and coastal ...

Influence of 2015 flood on the distribution and occurrence of microplastic pellets along the Chennai coast, India

Veerasingam, S.; Mugilarasan, M.; Venkatachalapathy, R.; Vethamony, P. (Elsevier, 2016)

The sources, distribution, surface features, polymer composition and age of microplastic pellets (MPPs) in surface sediments along the Chennai coast during March 2015 (pre-Chennai flood) and November 2015 (post-Chennai ...

Projected impact of climate change on waves at Mumbai High

Pentapatim, S.; Deo, M.C.; Kerkar, J.; Vethamony, P. (Institution of Civil Engineers, 2015)

Structures built in the sea are traditionally designed according to historical climate observations or hindcasts. In geographical locations typical of India, such designs do not take the effect of future climate change ...

Verification of model wave heights with long-term moored buoy data: Application to wave field over the Indian Ocean

Samiksha, S.V.; Polnikov, V.G.; Vethamony, P.; Rashmi, R.; Pogarskii, F.; Sudheesh, K. (Elsevier, 2015)

This paper describes the results obtained using a modified version (ModWAM) of the global wave model WAM, in which new parameterizations have been applied based on the seasonal changes and extreme weather events that have ...

Backtrack modeling to locate the origin of tar balls depositing along the west coast of India

Suneel, V.; Ciappa, A.; Vethamony, P. (Elsevier, 2016)

Tar ball (TB) deposition along the West Coast of India (WCI) is a common phenomenon during the southwest monsoon season, particularly along the coast of Goa and Gujarat, and it is a major concern to the stake holders. Our ...

Sources, vertical fluxes and accumulation of petroleum hydrocarbons in sediments from the Mandovi Estuary, west coast of India

Veerasingam, S.; Vethamony, P.; ManiMurali, R.; Babu, M.T. (University of Tehran, 2015)

The Mandovi estuary is highly influenced by mining and tourism related activities in the central west coast of India. Vertical fluxes and accumulation of petroleum hydrocarbons (PHCs) in three sediment cores (D1, C1 and ...

Reevaluation of design waves off the western Indian coast considering climate change

Satyavathi, P.; Deo, M.C.; Kerkar, J.; Vethamony, P. (Marine Technology Society, 2016)

Knowledge of design waves with long return periods forms an essential input to many engineering applications, including structural design and analysis. Such extreme or long-term waves are conventionally evaluated using ...

Detection of decadal shoreline changes along Dhamara and Maipura coast, Odisha, India

ManiMurali, R.; Dhiman, R.; Jayakumar, S.; Ilangovan, D.; Vethamony, P. (IAHR-AIRH, 2014)

Coastal erosion is one of the major problems of the coastal zone. The erosion is triggered by various reasons such as high wave energy, reduction of sediments, natural disasters and climate change etc. In the era of ...
