Contrasting features of tropospheric turbulence over the Indian peninsula
(2020)Altitude structure of turbulence in the troposphere and lower stratosphere (TLS) over the Indian peninsula is delineated using radiosonde observations carried out from six stations (August 2013 to December 2017) as part ... -
Operationally defined mercury (Hg) species can delineate Hg bioaccumulation in mangrove sediment systems: A case study
(2020)This study investigated the linkage between mercury (Hg) speciation in the surficial sediments from a mangrove ecosystem of the Zuari Estuary, west coast of India, with Hg bioaccumulation in gastropods collected from the ... -
High abundance of Vibrio in tarball-contaminated seawater from Vagator beach, Goa, India
(2020)Tarballs are semi-solid remnants of crude oil and they are formed in marine environment after oil-spill incidents. They are composed of diverse hydrocarbons; some of which are recalcitrant in nature. Recent studies based ... -
Assessment of crustal element and trace metal concentrations in atmospheric particulate matter over a coastal city in the Eastern Arabian Sea
(2020)Major/crustal elements (Al, Ca, Mg, K and Fe) and trace metals (Mn, Cr, Cu, Pb, Zn, and Ni) in atmospheric particulate matter at three sites in Goa (a coastal city in the Eastern Arabian Sea) were assessed during winter ... -
Phthalic acid esters - A grave ecological hazard in Cochin estuary, India
(2020)Distribution and ecological risks of Phthalic acid esters (PAEs) are poorly studied in estuarine environments in India. An attempt is made to chart the sources and assess the ecological risk of six PAE congeners (Σ6PAEs), ... -
Comparison of Neural Network Training Functions for Prediction of Outgoing Longwave Radiation over the Bay of Bengal
(2020)Artificial Neural Network (ANN) is contributed in many fields for forecasting or prediction like medical field, Sensex, biometric, remote sensing, pattern recognition, etc. The beauty of ANN is that it is having a capability ... -
Diversity of Bacterial Community in the Oxygen Minimum Zones of Arabian Sea and Bay of Bengal as Deduced by Illumina Sequencing
(2020)The Indian Ocean harbors oxygen minimum zones (OMZs) in the Arabian Sea and Bay of Bengal, with dissolved oxygen < 20 M, located at the mid-depths of the water column. Till date, high-throughput sequence-data on depth-wise ... -
Sources and preservation dynamics of organic matter in surface sediments of Narmada River, India - Illustrated by amino acids
(2020)The preservation process of organic matter (OM) in estuarine environments determines the recycling and sinking of nutrients. This process requires the identification of sources, degradation states and the main processes ... -
Nearshore Waves and Littoral Drift Along a Micro-Tidal Wave-Dominated Coast Having Comparable Wind-Sea and Swell Energy
(2020)The nearshore wave characteristics and variations in littoral drift (longshore sediment transport; LST) are estimated based on different approaches for four years along the Vengurla coast, with comparable wind-sea and swell ... -
Wave crest height distribution during the tropical cyclone period
(2020)The wave crest height plays a vital role in designing both the fixed and floating marine structures. The present study examines the measured wave crest data at 18 m water depth off Visakhapatnam in the northwestern Bay of ... -
Variability of dissolved oxygen in the Arabian Sea Oxygen Minimum Zone and its driving mechanisms
(2020)The Arabian Sea hosts one of the most intense, perennial Oxygen Minimum Zones (OMZ) in the world ocean. Observations along a meridional transect at 68°E extending from 8 to 21°N showed large seasonal as well as interannual ... -
Circulation in the Gulf of Khambhat - A Lagrangian Perspective
(2020)The circulation of the Gulf of Khambhat (GoK) is studied from a Lagrangian point of view using a 2D numerical model. The model-predicted tide elevation and current speed are in agreement with the observations. Seasonal ... -
Wind-wave measurements and modelling in the shallow semi-enclosed Palk Bay
(2019)Wind-wave characteristics of the Palk Bay, a semi-enclosed water body, are studied by the wave measurements carried out at 2 locations during a one-year period. The analysis of wave data sets shows that wind-sea dominates ... -
Structure-Function Elucidation of a New ?-Conotoxin, MilIA, from Conus milneedwardsi
(2019)The a-Conotoxins are peptide toxins that are found in the venom of marine cone snails and they are potent antagonists of various subtypes of nicotinic acetylcholine receptors (nAChRs). Because nAChRs have an important role ... -
Flood estimation at ungauged catchments of western catchments of Karnataka, West coast of India
(2019)Many catchments in India are devoid of gauging stations. In the absence of measurements of stream flow, regional rainfall-runoff relationships developed over a hydro-meteorologically similar region may be used to estimate ... -
Optimization of the taxonomic resolution of an indicator taxon for cost-effective ecological monitoring: Perspectives from a heterogeneous tropical coastline
(2019)An important requirement towards formulating appropriate management and conservation measures for biological diversity is to devise efficient and cost-effective monitoring protocols that yield coherent data. Environmental ... -
Interactions of sulfur and methane-oxidizing bacteria in tropical estuarine sediments
(2019)The bacterial oxidation of sulfur and methane is central to the biogeochemical processes in sediments such as the tropical mangrove sediments. However, there is a lacuna of information on the seasonal interactions including ... -
Genome analysis of Marinobacter phage AS1 suggests its close interactions with host Marinobacter sp.
(2019)Marinobacter comprises a widespread and ecologically significant genus of marine bacteria with vast metabolic capabilities. However, very few reports on phages infecting this genus exist. In this study, we isolated and ... -
Chromate detoxification potential of Staphylococcus sp. isolates from an estuary
