Monsoon rainfall and contrasting source rocks influenced sediment composition of peninsular basins along the east coast of India (western Bay of Bengal)
(Elsevier Ltd, 2020)The peninsular India is characterized by remarkable variation in lithological composition as well as contrasting rainfall distribution patterns. The erosional and weathering history of these source rocks along with monsoonal ... -
Coral damage by recreational diving activities in a Marine Protected Area of India: Unaccountability leading to 'tragedy of the not so commons'
(Elsevier Ltd, 2020)Globally, coral reefs have drastically degraded due to local and global environmental stressors. Concurrently, coral reef tourism is rapidly growing in developing economies, which is one of many anthropogenic stressors ... -
Biogeochemical cycling in the low oxygen marine environments
(Elsevier B.V., 2020)Biogeochemistry is the interdisciplinary science of the composition and cycling of chemicalelements. Nitrogen and oxygen are two elements that are essential for living organisms and the sustenance of life on Earth. While ... -
Passive acoustic metrics to understand shallow water biodiversity off Malvan area in the west coast of India
(NISCAIR, 2020)Underwater soundscape monitoring is an effective method to understand the biodiversity of an ecosystem. In this context, quantitative characterization of shallow water soundscape of the Burnt Island located off Malvan area ... -
Optical characteristics of colored dissolved organic matter during blooms of Trichodesmium in the coastal waters off Goa
(Springer, 2020)Trichodesmium, a marine cyanobacterium, plays a significant role in the global nitrogen cycle due to its nitrogen fixing ability. Large patches of Trichodesmium blooms were observed in the coastal waters, off Goa during ... -
Microbial Ecosystem and Anthropogenic Impacts
(Springer, Singapore, 2020)Oceans are the most vulnerable sites for anthropogenic waste from domestic as well as industrial origin. Usually, marine ecosystems are exposed to most anthropogenic stressors ranging from sewage disposal to nuclear waste ... -
Tidal characteristics in the Gulf of Khambhat, northern Arabian Sea - based on observation and global tidal model data
(Elsevier, 2020)Summary Tidal characteristics of the Gulf of Khambhat are described based on measured and modelled sea-level data. Data were recorded at three locations inside and two locations outside the Gulf with record lengths of 6-12 ... -
Influence of eddies on phytoplankton composition in the Bay of Bengal
(Elsevier Ltd, 2020)Several cyclonic (CE) and anticyclonic (ACE) eddies form in the Bay of Bengal (BoB) and they expect to contain different proportion of nutrients due to divergence and convergence of waters respectively and may have impact ... -
Evidence for brown carbon absorption over the Bay of Bengal during the southwest monsoon season: a possible oceanic source
(Royal Society of Chemistry (RSC), 2020)Light-absorbing brown carbon aerosols can have a marine origin over the coastal oceans and are likely associated with the sea salt component emitted from the ocean surface - significantly contributes to aerosol radiative ... -
Comparative assessment of antioxidant potential of different body parts of the yellow seahorse, Hippocampus kuda (Bleeker, 1852): source of traditional medicine
(CSIR-NISCAIR, 2020)Antioxidant potential of different body parts such as seahorse internal organs (SIO), skin with bones (SSB), bones (SB) and muscle tissues (SM) of cultured yellow seahorse, Hippocampus kuda was assessed in terms of total ... -
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 ... -
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 ... -
Bioconversion of chitin and concomitant production of chitinase and N-acetylglucosamine by novel Achromobacter xylosoxidans isolated from shrimp waste disposal area
(Nature Research, 2020)Marine pollution is a significant issue in recent decades, with the increase in industries and their waste harming the environment and ecosystems. Notably, the rise in shellfish industries contributes to tons of shellfish ... -
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 ... -
Characterizing three shallow-water locations off Goa, India, using passive acoustic data
(Acoustical Society of America (ASA), 2020)In this study, an analysis of the passive acoustic data is carried out for the quantitative characterization of shallow-water acoustic environments from three major estuarine systems of Goa during the months of March and ... -
Effect of undulating bottom on wave interaction with a floating flexible plate coupled with a flexible porous barrier
(Springer, 2020)In the present study, under the assumption of small amplitude water wave theory and structural response, effect of bed undulation on the wave interaction with a combination of flexible porous barrier and a flexible floating ... -
Hilbert-Huang transform analysis of surface wavefield under tropical cyclone Hudhud
(Elsevier Ltd, 2020)The characteristics of an evolving ocean surface wavefield under tropical cyclone Hudhud that took place in October 2014 are investigated. The Hilbert-Huang transformation (HHT) is used for the spectral analysis of the ... -
Extending the limit of widespread dispersed Toba volcanic glass shards and identification of new in-situ volcanic events in the Central Indian Ocean Basin
