Buried channels provide keys to infer Quaternary stratigraphic and paleo-environmental changes: A case study from the west coast of India
(2019)High resolution shallow seismic data was acquired from inner continental shelf of Goa, west coast of India to map underlying stratigraphic and buried geomorphic features of shelf strata. Seismic data revealed characteristic ... -
The community structure of the deep-sea nematode community associated with polymetallic nodules in the Central Indian Ocean Basin
(2019)Technological advances have led to an increase in the number of investigations in the deep sea over the last two decades. However, despite a large number of scientific cruises, few published data on the nematode biodiversity ... -
Integrated geophysical appraisal of crustal structure and tectonic evolution of the Angria Bank, western continental margin of India
(2019)Angria Bank, a submerged plateau with coral reefs, is located off the central-west coast of India. Biologically, the bank attracts scientific community for its coral formations. But geologically, origin and tectonic setting ... -
Characterization of marine bacterial carbonic anhydrase and their CO2 sequestration abilities based on a soil microcosm
(2019)The novel technology of biological carbon sequestration using microbial enzymes have numerous advantages over conventional sequestration strategies. In the present study, extracellular carbonic anhydrase (CA) producing ... -
Carbon isotopic and biochemical fingerprints of sedimentary organic matter in lower Narmada and Tapi rivers, north-west coast of India
(2019)Sources of organic matter (OM) in lower Narmada and Tapiriver-estuaries were examinedusing organic carbon to nitrogen ratio (Corg/N),stable carbon isotope ratio ( 13Corg) andlignin phenol biomarkers. The signature of ... -
Ecological implications of recently discovered and poorly studied sources of energy for the growth of true fungi especially in extreme environments
(2019)Rhodopsin transmembrane proton pumps (fuelled by visible light which is absorbed by retinal (carotenoid) chromophores) exist in all three domains of living species and in all groups of true fungi studied. Light driven ... -
2D NMR Studies of Bromotyrosine Alkaloid, Purpurealidin K from Marine Sponge Psammaplysilla purpurea
(2019)Marine sponges of the order Verongida and related organisms are the richest source of bioactive bromotyrosine alkaloids. Purpurealidin K (1) along with purealidin Q (2), aerophobin 2 (3) and aplysamine 2 (4) were isolated ... -
Persistence of fecal indicator bacteria associated with zooplankton in a tropical estuary-west coast of India
(2019)In a study carried out during 2014, bacteria associated with zooplankton in the Zuari estuary were 3– 4 orders of magnitude higher in abundance than in seawater. The live zooplankton carried much more bacterial load ... -
Modifications in the trace gases flux by a very severe cyclonic storm, Hudhud, in the coastal Bay of Bengal
(2019)A very severe cyclonic storm, Hudhud, made landfall at Visakhapatnam city, the central east coast of India, on 12 October 2014 and it is the most destructive cyclone to ever hit the Indian subcontinent since the past two ... -
Distribution of total petroleum hydrocarbons in water, sediment and its impact on six commercially important fishes of Kundalika estuary, west coast of India
(2019)Kundalika estuary, which opens into the Arabian Sea along the west coast of India, receives effluents from industries situated on its bank. The Total Petroleum Hydrocarbons (TPHs) were studied using fluorescence spectrophotometer ... -
Extinction of Antimicrobial Resistant Pathogens Using Silver Embedded Silica Nanoparticles and an Efflux Pump Blocker
(2019)Control measures against antimicrobial resistant bacterial pathogens are important challenges in our daily life. In this study, we discuss the sensitivity and resistance of four bacterial pathogens, Vibrio alginolyticus, ... -
Attenuation of Wave Energy Due to Mangrove Vegetation off Mumbai, India
(2019)Coastal regions of India are prone to sea level rise, cyclones, storm surges, and human-induced activities, resulting in flood, erosion, and inundation, and some of these impacts could be attributed to climate change. ... -
Determination of spatio-temporal influences on the distribution of fecal indicator organisms along the north-west coast of India
(2019)Coastal ecosystem is susceptible to discharge of untreated sewage waste. The present study is aimed to determine water quality status prevailing along the northwest coast of India by monitoring spatial and temporal variations ... -
Long-Term Variations in Nearshore Wave Climate and Littoral Drift at Ganpatipule Coast, Eastern Arabian Sea and its Link to Pacific Climate Variability
(2019)Nearshore wave characteristics and its variations at Ganpatipule coast, eastern Arabian Sea, for the past 4 decades (1979-2016) have been examined. The study is based on European Centre for Medium-Range Weather Forecasts ... -
Looking for the Harappan Ports around Dholavira, Khadir Bet, Kachchh, Gujarat
(2019)The rise of Harappan settlement at Dholavira is attributed to multidimensional factors which may include industrial activities, overseas trade and commerce and distribution of resources available in the Kachchh to other ... -
Did Romans have direct maritime trade contacts with Odisha on the Eastern Indian littoral?
(2019)Kalinga, Utkal, Odra and Orissa are former names of the present state of Odisha with varied geographical boundaries in different periods of history. The exploration and excavations of Manikapatna, Palur, Radhanagar, ... -
Chromium speciation in the sediments across the oxygen minimum zone, western continental margin of India
(2019)This study suggests that varying concentration of dissolved oxygen of overlying bottom water influences geochemical fractionation, speciation, and oxidation state of sedimentary Cr in a marine system. The nature of sedimentary ... -
