Denitrification rates of culturable bacteria from a coastal location turning temporally hypoxic

Gomes, J.; Khandeparker, R.; Naik, H.; Shenoy, D.M.; Meena, R.M.; Ramaiah, N. (Elsevier B.V., 2020)

Nitrate reduction plays a key role in the biogeochemical dynamics and microbial ecology of coastal upwelling systems. Seasonal upwelling in the eastern Arabian Sea entrains nitrate rich waters to the surface, the intense ...

(Elsevier, 2017)

Both in-situ and space-borne observations reveal an extremely high loading of particulates over the Indo-Gangetic Plains (IGP), all year around. With a burgeoning population and combustion sources (fossil fuels (FFs) and ...

Stable carbon and nitrogen isotopic composition of PM10 over Indo-Gangetic Plains (IGP), adjoining regions and Indo-Himalayan Range (IHR) during a winter 2014 campaign

Sen, A.; Karapurkar, S.G.; Saxena, M.; Shenoy, D.M.; Chaterjee, A.; Choudhuri, A.K.; Das, T.; Khan, A.H.; Kuniyal, J.C.; Pal, S.; Singh, D.P.; Sharma, S.K.; Kotnala, R.K.; Mandal, T.K. (Springer Berlin Heidelberg, 2018)

For source identification, a field campaign involving simultaneous sampling of particulate matter (PM10) was conducted at eight sampling sites in the Indian mainland during winter 2014. The sampling sites include Delhi ...

Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon

Chndrasekhararao, A.V.; Kurian, S.; Vidya, P.J.; Gauns, M.; Shenoy, D.M.; Mulla, A.; Naik, H.; Reddy, T.V.; Naqvi, S.W.A. (Elsevier, 2018)

Phytoplankton abundance and composition in two contrasting physical regimes - convective mixing in the northeastern Arabian Sea (NEAS) and Arabian Sea mini warm pool (ASMWP) in the southeastern Arabian Sea (SEAS) - were ...

Study on Ambient Air Quality of Megacity Delhi, India During Odd-Even Strategy

Sharma, S.K.; Agarwal, P.; Mandal, T.K.; Karapurkar, S.G.; Shenoy, D.M.; Peshin, S.K.; Gupta, A.; Saxena, M.; Jain, S.; Sharma, A.; Saraswati (Springer India, 2017)

State Government of Delhi had adopted odd-even scheme on vehicles plying in megacity Delhi to understand and improve the air quality of Delhi. To understand the effect of odd-even scheme on the concentration of pollutants, ...

pH variability off Goa (eastern Arabian Sea) and the response of sea urchin to ocean acidification scenarios

Shetye, S.S.; Naik, H.; Kurian, S.; Shenoy, D.M.; Nandakumar, K.; Fernandes, Michelle; Hussain, A. (Blackwell Publishing Ltd, 2020)

The increasing atmospheric CO2 concentration in the last few decades has resulted in a decrease in oceanic pH. In this study, we assessed the natural variability of pH in coastal waters off Goa, eastern Arabian Sea. pHT ...

Variation of biogenic sulphur compounds in the estuarine and coastal waters of Goa, West coast of India

Borker, S.G.; Shenoy, D.M.; Bepari, F.; Kurian, S.; Uskaikar, H. (NIScPR-CSIR, India, 2022)

Dimethylsulphide (DMS) originates predominantly from dimethylsulphoniopropionate (DMSP), a metabolite produced by phytoplankton.Through its contribution to the production of new aerosols and cloud condensation nuclei, a ...

Observational insights into chlorophyll distributions of subtropical South Indian Ocean eddies

Dufois, F.; Hardman-Mountford, N.J.; Fernandes, M.; Wojtasiewicz, B.; Shenoy, D.M.; Slawinski, D.; Gauns, M.; Greenwood, J.; Toresen, R. (Wiley-Blackwell, 2017)
