Massive coral bleaching in the patchy reef of Grande Island, along the eastern Arabian Sea during the 2015/16 global bleaching event
(Elsevier B.V., 2020)The 2014-2017 mass bleaching event is considered the third massive coral global bleaching event in recorded history. Based on the National Oceanic and Atmospheric Administration�s (NOAA) Coral Reef Watch (CRW) product ... -
Terrestrial and marine bioluminescent organisms from the Indian subcontinent: a review
(Springer Science and Business Media Deutschland GmbH, 2020)The inception of bioluminescence by Harvey (1952) has led to a Nobel Prize to Osamu Shimomura (Chemistry, 2008) in biological research. Consequently, in recent years, bioluminescence-based assays to monitor toxic pollutants ... -
Provenance tracing of long-range transported dust over the Northeastern Arabian Sea during the southwest monsoon
(Elsevier BV, 2020)One of the major pathways for dust supply to surface water of the Arabian Sea is via wet deposition, which is significant during southwest Monsoon (June-September). Aeolian dust supplies macro and micronutrients, which can ... -
Sub-surface magma movement inferred from low-frequency seismic events in the off-Nicobar region, Andaman Sea
(Nature Publishing Group, 2020)Monitoring volcanic activity along the submarine volcanoes that are usually induced by subsurface magmatism is a challenge. We present fresh set of Ocean Bottom Seismometer (OBS) data that shows geophysical evidence ... -
Bio-Decolorization of Synthetic Dyes by a Halophilic Bacterium Salinivibrio sp.
(Frontiers, 2020)Synthetic dyes, extensively used in various industries, act as pollutants in the aquatic environment, and pose a significant threat to living beings. In the present study, we assessed the potential of a halophilic bacterium ... -
Increased cyclone destruction potential in the Southern Indian Ocean
(IOP Publishing, 2020)The present study examines the role of the Southern Indian Ocean (SIO) warming on the cyclone destruction potential or Power Dissipation Index (PDI) during two contrasting periods of 1980-1998 and 1999-2016. The PDI in the ... -
Geomicrobial dynamics of Trans-Himalayan sulfur-borax spring system reveals mesophilic bacteria's resilience to high heat
(Springer, 2020)Geomicrobiology of sulfur-boron-dominated, neutral-pH hydrothermal systems was revealed in a Trans-Himalayan spring named Lotus Pond, located at 4436 m, in Puga Valley, Ladakh (India), where water boils at 85°C. Water ... -
Montmorillonite and phosphorus enrichment in sediments as the causative factor for mud bank formation along the southwest coast of India
(Elsevier B.V., 2020)Mud banks of Kerala (southwest coast of India) are renowned for immense fish harvesting during the southwest monsoon season. Although inclement weather and turbulent waves during monsoon prevent vessels sailing into the ... -
Impact of remote equatorial winds and local mesoscale eddies on the existence of "River in the Sea" along the East coast of India inferred from satellite SMAP
(American Geophysical Union (AGU), 2020)The Northern Bay of Bengal (NBOB) exhibits extreme salinity stratification caused by intense summer monsoon rainfall and associated river discharge. This accumulated fresh water plume in NBOB is believed to be transported ... -
Current asymmetry and its implications for morphological changes in Vembanad Lake, the second largest wetland ecosystem in India
(Elsevier, 2020)Flow dynamics are a key part of the physical processes that drive the sediment transport in an aquatic system, affecting depositional processes and leading to landform evolution. The current asymmetry (CA) noted in Vembanad ... -
A highly diverse living benthic foraminiferal assemblage in the oxygen deficient zone of the southeastern Arabian Sea
(Springer Science and Business Media B.V., 2020)The exchange of seawater between the Arabian Sea and the Bay of Bengal, creates a strong seasonality in the southeastern Arabian Sea, including the oxygen deficient zone (ODZ) at intermediate depth. Here, we assess the ... -
Extracellular polymeric substances mediate the coaggregation of aquatic biofilm-forming bacteria
(Springer Science and Business Media Deutschland GmbH, 2020)Coaggregation, a phenomenon contributing to biofilm formation, occurs among biofilm bacteria from different aquatic environments. However, not much is known about molecules involved in aggregation. In this study, freshwater, ... -
Report of ciliate-bryozoan-crustacean hyperepibiosis on crab (Decapoda: Brachyura) from west coast of India, Arabian Sea
(Magnolia Press, 2020)Epibiosis is a common phenomenon, found in different taxa of aquatic animals. This relationship could occur as hyperepibiosis, when a basibiont being also an epibiont, providing a stable substrate for the hypersymbiont. ... -
