Trace metal distribution in the sediment cores of mangrove ecosystems along northern Kerala coast, south-west coast of India
(Elsevier Ltd, 2020)Core sediment samples were collected from five mangrove ecosystems along northern Kerala coast (Kunjimangalam: S1, Pazhayangadi: S2, Pappinissery: S3, Thalassery: S4, and Kadalundi: S5) to assess the status of heavy metal ... -
Climatology of wave period in the Arabian Sea and its variability during the recent 40 years
(Elsevier Ltd, 2020)Information on wave period is required for designing marine facilities. Characteristics of peak period (Tp) can reveal swell or wind-sea predominance at a location. Mean wave period (Tm) and Tp from reanalysis data spanning ... -
Closing the sea surface mixed layer temperature budget from in situ observations alone: Operation Advection during BoBBLE
(Nature Publishing Group, 2020)Sea surface temperature (SST) is a fundamental driver of tropical weather systems such as monsoon rainfall and tropical cyclones. However, understanding of the factors that control SST variability is lacking, especially ... -
Occurrence of Gravity and Infra Gravity Waves in the Nearshore Region at Ratnagiri, West Coast of India
(Coastal Education and Research Foundation, 2020)This study analyses the sea level data measured simultaneously using S4DW and directional Wave Rider Buoy (WRB) off Ratnagiri, eastern Arabian Sea, located along the west coast of the Indian sub-continent. The objective ... -
A Mesohaline Thraustochytrid Produces Extremely Halophilic Alpha-Amylases
(Springer, 2020)Halophilic bacteria are well known to produce highly salt-tolerant enzymes that have unusual applications in biotechnology. Production of halophilic proteins is generally not expected in mesohaline microorganisms. Ulkenia ... -
Does the Laxmi Ridge continue towards the Laccadive Ridge? New insights from an integrated geophysical study
(Pergamon, 2020)The Laxmi and Laccadive ridges are two major aseismic ridges in the NW Indian Ocean. Bathymetry, gravity and magnetic data and their derivatives are analyzed and modelled to assess interrelationship between both the ridges ... -
Effect of freshwater advection and winds on the vertical structure of chlorophyll in the northern Bay of Bengal
(Elsevier, 2020)The northern Bay of Bengal receives a large amount of fresh water through river runoff and rainfall during the Indian summer monsoon (June-September). This fresh water spreads offshore and can modulate the upper-ocean ... -
Sources and implications of particulate organic matter from a small tropical river-Zuari River, India
(Springer Verlag, 2020)Transitional ecosystems, estuaries and the coastal seas, are distinctively affected by natural and anthropogenic factors. Organic matter (OM) originating from terrestrial sources is exported by rivers and forms a key ... -
Characterization of coral associated ciliates and their interactions with disease lesion progression of Indian Scleractinian corals
(Elsevier, 2020)Ciliates associated with advanced diseased lesions of Acropora sp. and Porites sp. in the field were isolated and characterised using microscopic and molecular analysis. The identified dominant coral-associated ciliates ... -
Phylogenetic Diversity of Culturable Marine Bacteria from Mangrove Sediments of Goa, India: a Potential Source of Xylanases Belonging to Glycosyl Hydrolase Family 10
(Pleiades Publishing Ltd, 2020)Xylan is one of the most abundant polysaccharides present in softwoods and hardwoods. Microbial xylanases mainly mediate its degradation. Xylanase has biotechnological potential with enormous demand in industries. The ... -
The Significance of Denitrification in the Nitrogen Cycle
(Cambridge Scholars Publishing, New castle, UK, 2020)Nitrogen fluxes from marine systems to the atmosphere are between 25x10 9 and 179x10 9 kilograms per year and from terrestrial systems, between 90x10 9 and 243x10 9 kilograms per year via microbial denitrification. ... -
Research opportunities in pandemic lockdown
(American Association for the Advancement of Science, 2020)The entire world is facing an unprecedented crisis today due to the spread of COVID-19. The most severely affected countries enforced a complete lockdown to minimize personal contacts, with only bare minimum, essential ... -
Habitat characteristics mediated partitioning of economically important bivalves in a tropical monsoon-influenced estuary
(Springer, 2020)Bivalves are benthic organisms inhabiting coastal marine habitats, especially estuarine tidal and mudflats. Due to their high stocking density and rich protein content, they form a major part of the artisanal fishery ... -
Imprints of ancient recycled oceanic lithosphere in heterogeneous Indian Ocean mantle: Evidence from petrogenesis of Carlsberg ridge basalts from Northwest Indian Ocean
(Elsevier Inc., 2020)This paper reports new petrological, geochemical and isotopic data for Carlsberg Ridge Basalts (CRB) of northwest Indian Ocean and evaluates their petrogenetic aspects in the context of the geochemical and tectonic evolution ... -
Large-scale mass wasting on the miocene continental margin of Western India
(Geological Society of America, 2020)A giant mass-transport complex was recently discovered in the eastern Arabian Sea, exceeding in volume all but one other known complex on passive margins worldwide. The complex, named the Nataraja Slide, was drilled by ... -
Distinctive Community Patterns With Exceptional Diversity of Polychaetes Around a Tectonically Active Archipelago in the Tropical Indian Ocean
(Frontiers, 2020)Marine soft-sediments sustain functionally important benthic assemblages that are critical for remineralization of organic matter and supply of nutrients to the water column. While these assemblages are well studied along ... -
Recently Discovered Iron Anchors from Tamil Nadu, East Coast of India
(Ubiquity Press, 2020)In maritime archaeological studies, anchors made of stone, wood, or metal have played a significant role in shipping, not only acted as a proxy during the period of their use but also suggesting maritime connections with ... -
