Coastal Archaeological Explorations on the Eastern Margin of the Little Rann of Kachchh, Gujarat
(The Indian Society for Prehistoric and Quaternary Studies (ISPQS), 2019)A coastal archaeological exploration was carried out on the eastern margin of the Little Rann of Kachchh to document the ancient remains of coastal settlements, port installations and any other aspects related to maritime ... -
Isolation and characterization of a moderately halophilic Marinobacter phage-host system from the Arabian Sea
(Springer, 2020)Marinobacter is an ecologically important genus of Gammaproteobacteria found in diverse marine habitats, many species of which are capable of degrading hydrocarbons. In this study, we isolated a Marinobacter phage-host ... -
Late Quaternary Chronostratigraphy, Carbonate Mass Accumulation Rates and Palaeoceanography of the Andaman Sea
(Springer, Cham, 2020)The Andaman Sea, the least explored semi-enclosed marginal sea in the northern Indian Ocean, is one of the great repositories of palaeo-sedimentary archives for Quaternary climate and oceanographic studies due to its ... -
Environmental Reservoirs of Vibrio cholerae: Challenges and Opportunities for Ocean-Color Remote Sensing
(MDPI AG, 2019)The World Health Organization has estimated the burden of the on-going pandemic of cholera at 1.3 to 4 million cases per year worldwide in 2016, and a doubling of case-fatality-rate to 1.8% in 2016 from 0.8% in 2015. The ... -
Archaeological Explorations of Kalingapatnam, Dantapur and Salihundam on the East Coast of India
(The Indian Society for Prehistoric and Quaternary Studies (ISPQS), 2019)There are several coastal sites along the east and west coast of India from the Harappan period onwards which served as port and trade centres. Among ancient ports along the east coast of India, Kalingapatnam, Dantapur, ... -
Recent contributions to the geochemistry and sedimentology of estuaries, mangroves, and mudbanks along the Indian coast: A status report
(Indian National Science Academy, 2020)In the last four years, significant progress has been made in biogeochemical/ geochemical and sedimentological studies of the coastal sediments along the east and west coasts of India. The present review highlights the ... -
A significant shift in particulate organic matter characteristics during flooding of River Krishna, eastern peninsular India
(Current Science Association, IAS, 2020)Extremely heavy rainfall over a small, semi-arid section of the Indian Peninsula in October 2009, together with release of water from dams resulted in very severe flooding in River Krishna. The sources and type of organic ... -
Bacterial Communities Associated With Healthy and Diseased (Skeletal Growth Anomaly) Reef Coral Acropora cytherea From Palk Bay, India
(Frontiers Media S.A., 2020)Skeletal growth anomalies (SGA) are easily recognizable disease in reef-forming corals which drain energy from the host and end up with mortality. We collected mucus samples of healthy and SGA affected colonies of Acropora ... -
Functional characterization of anti-cancer sphingolipids from the marine crab Dromia dehanni
(Elsevier Ireland Ltd, 2019)Sphingolipids have been considered for many years only as structural components of membranes. It is now acknowledged that they are also involved in controlling cellular processes such as proliferation.The present work was ... -
Tectonics of the Andaman Backarc Basin-Present Understanding and Some Outstanding Questions
(Springer, Cham, 2020)The Andaman Backarc Basin is characterized by active seafloor spreading spurred by the right stepping dextral shear imposed on the trans-basinal Sagaing-Andaman-Nicobar- Sumatra fault system and presents a complex tectonic ... -
Influence of tropical cyclones on the 100-year return period wave height- A study based on 39-year long ERA5 reanalysis data
(John Wiley and Sons Ltd, 2020)Various engineering activities in a coastal and offshore environment require detailed assessment about the probable extreme wave characteristics in its lifetime to prevent human as well as property loss. The accurate ... -
Comparison of bacterial diversity from two mangrove ecosystems from India through metagenomic sequencing: Comparative mangrove bacterial diversity using metagenomics
(Elsevier B.V., 2020)In the present study, we explored the microbial diversity of two mangrove regions, Mangalavanam (MAN) and Puthuvype (PVY), in Cochin, India. While PVY is a coastal island, MAN lies in the heart of the mainland of Cochin, ... -
What Controls the Flushing Efficiency and Particle Transport Pathways in a Tropical Estuary? Cochin Estuary, Southwest Coast of India
(MDPI AG, 2020)Estuaries with poor flushing and longer residence time retain effluents and pollutants, ultimately resulting in eutrophication, a decline in biodiversity and, finally, deterioration of water quality. Cochin Estuary (CE), ... -
Lack of denitrification causes a difference in benthic foraminifera living in the oxygen deficient zones of the Bay of Bengal and the Arabian Sea
(Elsevier Ltd, 2020)Despite being located at the same latitudes, the Bay of Bengal oxygen deficient zone (ODZ) is markedly different than the Arabian Sea ODZ. The uptake of oxygen in the Bay of Bengal does not lead to denitrification as in ... -
A Preliminary Study of Knobbed Ware from Odisha
(The Indian Society for Prehistoric and Quaternary Studies (ISPQS), 2019)Archaeological explorations and excavations across the length and breadth of the Indian subcontinent have revealed several distinct types of pottery which facilitated reconstruction of the past. In archaeology, research ... -
Quasi-biweekly oscillations in the Bay of Bengal in observations and model simulations
(Elsevier Ltd, 2019)Intraseasonal oscillations (ISOs) significantly contribute to the variability and strength of rainfall associated with the Indian Summer Monsoon. The westward-propagating, 10-20-day, quasi-biweekly ISO (QBWISO), in association ... -
Remote influences on the Indian monsoon low-level jet intraseasonal variations
(Springer, 2020)A strong low-level jet (LLJ), also known as the Findlater jet, develops over the Arabian Sea during the Indian summer monsoon. This jet is an essential source of moisture for monsoonal rainfall over the densely-populated ... -
