Diversity pattern of marine culturable heterotrophic bacteria in a region with coexisting upwelling and mud banks in the southeastern Arabian Sea
(Springer, 2022)Mud banks and upwelling are two important oceanographic features occurring along the southwest coast of India during the southwest monsoon period. The study region, Alappuzha lying on the southwest coast of India, is unique ... -
Impact of Dissolution of Saline-Alkaline Soils on the Hydrochemistry and Erosion Rates of the Ganga River System
(Wiley, 2022)We characterize here the saline-alkaline soils composed of Na2CO3 and NaHCO3 in the Ganga floodplain and the peninsular basin using various chemical proxies and the isotopic composition of Sr. Abundance of saline-alkaline ... -
Analysis of non-pharmaceutical interventions and their impacts on COVID-19 in Kerala
(Nature Publishing Group, 2022)In the absence of an effective vaccine or drug therapy, non-pharmaceutical interventions are the only option for control of the outbreak of the coronavirus disease 2019, a pandemic with global implications. Each of the ... -
Remote forcing of winter cooling in the Arabian Sea: Implications for the NE monsoon
(Elsevier, 2022)The regional climate in the Asian subcontinent is highly influenced by the Southwest Monsoon (SWM) and Northeast Monsoon (NEM) during boreal summer and winter, respectively. Although the response of the SWM to the abrupt ... -
The Synergistic Impacts of Anthropogenic Stressors and COVID-19 on Aquaculture: A Current Global Perspective
(Taylor & Francis, 2022)The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other ... -
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 ... -
A~30 kyr sub-centennial to millennial Indian summer monsoon variability record from the southern Andaman Sea, northeastern Indian Ocean
(Elsevier, 2022)This paper reports centennial-scale variations in the Indian summer monsoon (ISM) that induced stratification and resultant productivity changes in the southern Andaman Sea. The study is based on foraminifera assemblages ... -
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 ... -
Morphological description and molecular characterisation of green aggregating sea anemone, Anthopleura elegantissima (Brandt, 1835) (Cnidaria: Anthozoa) from southwest coast of India
(MBAI, Marine Biological Association of India, 2021)Green aggregating sea anemone, Anthopleura elegantissima (Brandt 1835) is found in the intertidal region of Thirumullavaram (Lat. 8°89’53“N, Long. 76°55.61”E), southwest coast of India. During the survey, individuals of ... -
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 ... -
Distinctive phytoplankton size responses to the nutrient enrichment of coastal upwelling and winter convection in the eastern Arabian Sea
(Elsevier, 2022)Even though the seasonal pattern of phytoplankton biomass distribution in the seas around India is reasonably well understood, there is relatively little information on phytoplankton size classes. The current study shows ... -
