Diagenetic dissolution, maghemitization and sulphidization of magnetic minerals in rapidly deposited gas hydrate bearing sediments from the Bay of Bengal
(Elsevier, 2022)
We conducted a comprehensive rock magnetic investigation complemented by a scanning electron microscopy analyses on a 148.8 m sediment core (NGHP-01-20A) from the methane-hydrate bearing site in the Bay of Bengal to ...
Microplastics in copepods reflects the manmade flow restrictions in the Kochi backwaters, along the southwest coast of India
(Elsevier, 2022)
This baseline study on microplastics (MPs) in calanoid copepods in the Kochi backwaters (KBW), India's largest estuary system on the west coast, focuses on (a) the spatiotemporal variations of MPs with the seasonal hydrography ...
Standing stock and composition of macrozoobenthos in the south-eastern Arabian Sea: A revisit after a decade
(Elsevier, 2022)
Changes in macrozoobenthic standing stock and composition along the south-eastern Arabian Sea continental shelf (30-200 m) are investigated, based on data collected from the same sites during the same season 14 years apart ...
Alarming waterweeds proliferation in the Vembanad Lake System might significantly increase water loss through transpiration
(Springer, 2022)
Eichhornia crassipes and Monochoria vaginalis are waterweeds, and their uncontrolled proliferation in fresh and brackish water habitats is a serious ecological problem in many parts of the world. These weeds are quite ...
Indus and Nubra Valley hot springs affirm the geomicrobiological specialties of Trans-Himalayan hydrothermal systems
(Springer, 2022)
Geomicrobiologies of the hot springs of Chumathang and Panamik (located in the Indus and Nubra valleys of eastern and northern Ladakh, respectively) were revealed and compared with the Lotus Pond spring of Puga Valley ...
Marine microbial enzymes for the production of algal oligosaccharides and its bioactive potential for application as nutritional supplements
(Springer, 2022)
Marine macroalgae have a very high carbohydrate content due to complex algal polysaccharides (APS) like agar, alginate, and ulvan in their cell wall. Despite numerous reports on their biomedical properties, their hydrocolloid ...
Warm northern tropical Indian Ocean strengthened the ocean circulation prior to the last glacial termination
(Elsevier, 2022)
Modern observations and model simulations suggest a strong influence of tropical processes on high-latitudinal climate. The evidence of similar tropics-high latitude climate link during glacial termination is, however, ...
Contrasts in calcium carbonate dissolution above the lysocline in the equatorial Indian Ocean over the last ~40 ka
(Elsevier, 2022)
Understanding calcite dissolution above the lysocline is crucial to comprehend the oceanic calcium carbonate cycle. To understand past calcite dissolution in sediments from above the lysocline, we use multiple dissolution ...
Ciliated protozoan occurrence and association in the pathogenesis of coral disease
(Elsevier, 2022)
Various microbial infections have significantly contributed to disease progression leading to the mortality of corals. However, the holobiont and the external surfaces of coral, including the secreted mucus, provide a ...
Multistage melt impregnation in Tethyan oceanic mantle: Petrochemical constraints from channelized melt flow in the Naga Hills Ophiolite
(Elsevier, 2022)
Ophiolitic sequences obducted onto continental margins allow field based observations coupled with petrochemical interrogations of upper mantle lithologies thereby aiding evaluation of compositional heterogeneity of oceanic ...
