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
(Springer, 2020)We report the widespread extent of Toba volcanic glass shards in the Central Indian Ocean Basin. Investigation of four sediment cores (7o-17oS) revealed several shard-rich horizons (SRH) that provide the first detailed ... -
A roadmap to IndOOS-2: Better observations of the rapidly-warming Indian Ocean
(American Meteorological Society, 2020)The Indian Ocean Observing System (IndOOS), established in 2006, is a multinational network of sustained oceanic measurements that underpin understanding and forecasting of weather and climate for the Indian Ocean region ... -
Autonomous profiling float observations reveal the dynamics of deep biomass distributions in the denitrifying oxygen minimum zone of the Arabian Sea
(Elsevier B.V., 2020)Data from 13 autonomous profiling BGC-Argo floats, equipped with biogeochemical and bio-optical sensors deployed between 2011 and 2016, were used to explore the potential of bio-optical methods to map deep biomass distribution ... -
Salmonella Contamination of Seafood in Landing Centers and Retail Markets of Mumbai, India
(Oxford University Press (OUP), 2020)Background: Seafood contamination with Salmonella enterica is not only a public health concern, but can also lead to economic losses due to import rejections. Continuous monitoring of seafood for Salmonella is necessary ... -
Watercraft depicted in the art of Odisha, East Coast of India
(Australasian Institute for Maritime Archaeology, 2018)The Indian state of Odisha, with its long coastline facing the Bay of Bengal, extensive riverine network and convenient anchorages, has enjoyed a sustained maritime history. Nevertheless, the lack of archaeological excavation ... -
Pyrone-derived Marine Natural Products: A Review on Isolation, Bio-activities and Synthesis
(Bentham Science Publishers Ltd., 2020)Marine natural products (MNPs) containing pyrone rings have been isolated from numerous marine organisms, and also produced by marine fungi and bacteria, particularly, actinomycetes. They constitute a versatile structure ... -
Influence of salinity stress on bacterial diversity from a marine bioinvasion perspective: evaluation through microcosm experiments
(Current Science Association, IAS, 2020)Mid-ocean ballast water exchange has been used since the past few years to control bioinvasion through ballast water (BW), which requires the ship to exchange part of its BW in the open ocean. The change in salinity is ... -
Massive Nitrogen Loss Over the Western Indian Continental Shelf During Seasonal Anoxia: Evidence From Isotope Pairing Technique
(Frontiers Media SA, 2020)The western Indian continental shelf houses the world's largest naturally formed coastal low-oxygen zone that develops seasonally during the summer monsoon. We investigated multiple reductive nitrogen transformation pathways ... -
Signals of selection in the mitogenome provide insights into adaptation mechanisms in heterogeneous habitats in a widely distributed pelagic fish
(Nature Research, 2020)Oceans are vast, dynamic, and complex ecosystems characterized by fluctuations in environmental parameters like sea surface temperature (SST), salinity, oxygen availability, and productivity. Environmental variability acts ... -
The impacts of ocean acidification on marine trace gases and the implications for atmospheric chemistry and climate
(Royal Society Publishing, 2020)Surface ocean biogeochemistry and photochemistry regulate ocean-atmosphere fluxes of trace gases critical for Earth�s atmospheric chemistry and climate. The oceanic processes governing these fluxes are often sensitive to ... -
Massive Methane Loss During Seasonal Hypoxia/Anoxia in the Nearshore Waters of Southeastern Arabian Sea
(Frontiers Media S.A., 2020)Repeat observations over the Kochi and Mangalore shelves of the southeastern Arabian Sea (SEAS) during April to December 2012 revealed substantial accumulation of methane (CH4) in the nearshore waters (48.6 � 34.4 nM) ... -
Copepods size structure in various phases of a cold-core eddy - Normalised Abundance Size Spectra (NASS) approach.
(Pergamon, 2020)The present study addresses the copepods size structure in different phases of a cold-core eddy based on a 17 day time-series measurement (21st February to 8th March 2016) from a coastal site in the western Bay of Bengal ... -
Sources of organic matter and tracing of nutrient pollution in the coastal Bay of Bengal
(Pergamon, 2020)Stable isotopic composition of carbon (delta13CPOM) and nitrogen (delta15NPOM) in the particulate organic matter (POM) is used to identify sources of organic carbon and nutrients using monthly time-series observation in ... -
A coherent response of Southern Indian Ocean to the Antarctic climate: Implications to the lead, lags of atmospheric CO2 during deglaciation
(Springer, 2020)A record of delta18Oc from the Indian sector of Southern Ocean and atmospheric CO2, and delta18O of European Project for Ice Coring in Antarctica (EPICA) and Greenland Ice Sheet Project 2 (GISP2) reveals that a coherent ... -
Aberrations in the microbiome of cyanobacteria from a tropical estuary polluted by heavy metals
(Elsevier Ltd, 2020)The effect of heavy metal pollution on the microbiome of cyanobacteria in Cochin estuary (CE) on the southwest coast of India is reported in the study. Statistically significant difference in heavy metal concentration was ... -
The Global Implications of the Nitrogen Cycle: A Benthic Community Perspective
(Cambridge Scholars Publishing, New castle, UK, 2020)The benthic ecosystem comprising coral reefs, seaweed, and seagrass beds contributes to organic matter mineralisation, food for many invertebrates and fishes, and plays a significant role in regulating the various ... -
Oceanic rocks beneath the landmass and continental rocks below the ocean - geological complexities in Indian waters
