High abundance of Vibrio in tarball-contaminated seawater from Vagator beach, Goa, India
(2020)
Tarballs are semi-solid remnants of crude oil and they are formed in marine environment after oil-spill incidents. They are composed of diverse hydrocarbons; some of which are recalcitrant in nature. Recent studies based ...
Tidal Triggering of the Harmonic Noise in Ocean-Bottom Seismometers
(Seismological Society of America (SSA), 2020)
We observed a harmonic noise (HN) in DEPAS ocean-bottom seismometers (OBSs) data recorded from the Andaman-Nicobar region. The HN is characterized by sharp spectral peaks with a fundamental frequency and several overtones ...
Response of particle-associated bacteria to long-term heavy metal contamination in a tropical estuary
(Springer, 2020)
Estuaries being the connecting link between terrestrial and marine environment, experience spatial variations in the hydrographic variables as well as concentrations of pollutants. The present study reports a contrasting ...
Assessment of crustal element and trace metal concentrations in atmospheric particulate matter over a coastal city in the Eastern Arabian Sea
(2020)
Major/crustal elements (Al, Ca, Mg, K and Fe) and trace metals (Mn, Cr, Cu, Pb, Zn, and Ni) in atmospheric particulate matter at three sites in Goa (a coastal city in the Eastern Arabian Sea) were assessed during winter ...
Impact of 2004 co-seismic coastal uplift on the mangrove cover along the North Andaman Islands
(Springer, 2020)
The December 2004 earthquake and the subsequent tsunami have incurred devastating impacts on vital habitats along the Indian coastal region, where few of them are irreversible. The earthquake has uplifted the northern ...
Modulation of chlorophyll concentration by downwelling Rossby waves during the winter monsoon in the southeastern Arabian Sea
(Elsevier Ltd, 2020)
Signatures of Rossby waves that are evident in satellite ocean colour data in the southeastern Arabian Sea (SEAS) are more prominent during the winter than the summer monsoon. During the winter, the sea level is high, and ...
Back-to-Back Occurrence of Tropical Cyclones in the Arabian Sea During October-November 2015: Causes and Responses
(American Geophysical Union (AGU), 2020)
In the Arabian Sea, two extremely severe cyclonic storms occurred back to back during October-November 2015. Using a suite of ocean and atmospheric data, we examined the upper ocean responses of tropical cyclones Chapala ...
COVID-19 lockdown induced air pollution reduction over India: A lesson for future air pollution mitigation strategies
(Springer, 2021)
Air pollution is one of the biggest problems worldwide and needs to be addressed potentially with the implementation of updated stringent policies and legislative laws. The nationwide lockdown imposed to prevent the COVID-19 ...
Tectonic appraisal of the Mid-Thane Creek of Mumbai, India: An integrated geophysical approach
(Springer, 2020)
Integrated geophysical surveys, comprising marine magnetic, high resolution shallow seismic and single-beam bathymetry were conducted to assess subsurface tectonics of the Mid-Thane Creek (MTC) of Mumbai. The bathymetry ...
Surface wave interactions with submerged horizontal viscoelastic sheets
(Elsevier, 2021)
In this study, the surface wave interactions with submerged horizontal viscoelastic sheets of varying rheological properties are investigated both experimentally and analytically. In the experiments, we adopt the novel ...
