Analysis of Bacteria-Phytoplankton relationships at three discrete locations in the Eastern Arabian Sea during winter
(Elsevier, 2022)Bacterial abundance (BA), bacterial production (BP), chlorophyll a (Chl a) and primary production (PP) were estimated during Dec 2016-Jan 2017 at three discrete locations viz. the coastal waters, oceanic waters and near ... -
Benthic-pelagic coupling assessed using phytoplankton marker pigments: a case study from the Paradip port, East Coast of India
(Springer, 2022)This study addresses the seasonal distribution of phytoplankton marker pigments (PMP) and the ratios (indicating freshness and fate) from water and surface sediments from the coastal port ecosystem (Paradip port, Odisha, ... -
Chemical composition of Low Moor and Walker Company cannons in the Odisha State Maritime Museum, east coast of India
(Current Science Association, IAS, 2022)Cannons are military or civil weapons supported on carriages or fixed mounts and used in warfare as well as against rebellions. Now, most of the cannons are exhibited in museums, forts, public and private buildings , and ... -
In-situ O-isotope analysis of relict spinel and forsterite in small (<200µm) Antarctic micrometeorites - Samples of chondrules & CAIs from carbonaceous chondrites
(Elsevier, 2022)We report high-precision secondary ion mass spectrometer triple oxygen isotope systematics (95 individual analyses) from 37 micrometeorites (MMs) collected from South Pole Water Well (SPWW), Antarctica. The study population ... -
Conjugate nature of the Alleppey-Trivandrum Terrace Complex with the Northern Madagascar Ridge in the early opening model of the Arabian Sea: evaluation based on an integrated geophysical investigation
(Springer, 2022)The southwestern continental margin of India reveals the presence of an anomalous bathymetric high feature located in the mid-continental slope region off Trivandrum. Based on the analysis of the available geophysical data ... -
Seasonal variability in environmental parameters influence bacterial communities in mangrove sediments along an estuarine gradient
(Elsevier, 2022)Mangrove ecosystems are repositories of divergent microbial communities which respond differently to environmental characteristics. Hence, it is important to understand the community structure with respect to pertinent ... -
A Path-Following Controller for Marine Vehicles Using a Two-Scale Inner-Outer Loop Approach
(MDPI, 2022)This article addresses the problem of path following of marine vehicles along straight lines in the presence of currents by resorting to an inner-outer control loop strategy, with due account for the presence of currents. ... -
Nitrogen fixation in the western coastal Bay of Bengal: Controlling factors and contribution to primary production
(Elsevier, 2022)N2 fixation rates were measured at 18 stations in the western coastal Bay of Bengal (BoB) to evaluate its contribution to the external source of nitrogen and its controlling factors. During the study period (fall monsoon), ... -
Dark survival in biofilm-forming microalgae: potential for colonizing benthic ecosystems
(Oxford Academic, 2022)The biofilm-forming microalgae are known to experience periods of continuous darkness (upto several days), in addition to the natural day-night cycle, especially in the intertidal sediment regions (when transported to ... -
Phytoplankton assemblage and chlorophyll a along the salinity gradient in a hypoxic eutrophic tropical estuary-Ulhas Estuary, West Coast of India
(Elsevier, 2022)Phytoplankton assemblage and chlorophyll a along the salinity gradient and oxygen zonation were studied in Ulhas Estuary. Oxic condition exist in euhaline region of the estuary that receives oxygenated coastal waters, ... -
Diagenetic analysis of shallow and deep-seated gas hydrate systems from the Bay of Bengal
(Elsevier, 2022)This is the first systematic high-resolution rock magnetic study complemented by mineralogical and petrological observations conducted on sediment cores representing shallow (active cold seep; SSD-45/Stn-4/GC-01) and ... -
Ecological Impacts of Aged Freshwater Biofilms on Estuarine Microbial Communities Elucidated Through Microcosm Experiments: A Microbial Invasion Perspective
(Springer, 2022)Inadvertent introductions of alien species via biofilms as a vector released through ballast water are of environmental importance, yet their consequences are not much known. In the present study, biofilm communities ... -
Chemical diversities, biological activities and chemical synthesis of marine diphenyl ether and their derivatives
(Elsevier, 2022)Marine organisms produce several secondary metabolites that find applications in pharmacology and biological systems. Vast biodiversity and unique environmental conditions endowed with marine ecosystem provide marine ... -
Seasonal, weathering and water use controls of silicon cycling along the river flow in two contrasting basins of South India
(Elsevier, 2022)We present the first study of river water silicon isotopic composition from two contrasting basins in South India, the east flowing Kaveri river and the west flowing Netravathi river. Both rivers originate from the Western ... -
Response of smaller plankton to the saltwater barrage-altered hydrography of a tropical estuarine system on India's southwest coast
(Elsevier, 2022)This study examines how a large saltwater barrage [Thannermukkom barrage (TB)] in the Kochi backwaters (KBW), India's largest estuarine system on the west coast, affects the distribution of autotrophic small plankton ... -
Strong solar influence on multi-decadal periodic productivity changes in the central-western Bay of Bengal
(Elsevier, 2022)Oceanic productivity is a vital component of the global carbon cycle. The productivity in the tropical oceans is strongly modulated by the monsoon winds. The monsoon winds are driven by the temperature. Therefore, the ... -
Ecological habitat quality assessment of a tropical estuary using macrobenthic functional characteristics and biotic indices
(Springer, 2022)Seasonal variation in the macrobenthic functional characteristics, such as trophic structure and secondary production, was studied, along with their structural characteristics such as density, biomass, and community ... -
Distribution of extant coccolithophores from the northwest continental shelf of India during the summer monsoon
(Taylor & Francis, 2022)Coccolithophores contribute substantially to marine primary production as well as to particulate inorganic carbon (PIC) flux to the deep sea; however, there is no literature available so far from the Indian continental ... -
