Intra- and inter-seasonal variability of nutrients in a tropical monsoonal estuary (Zuari, India).
(Elsevier, 2014)A study was conducted to understand the intra- and inter-seasonal variability of dissolved oxygen and nutrients in a tropical monsoon estuary (Zuari in Goa, India). We adopted a dual sampling approach with (a) daily or ... -
Early- to late-Holocene contrast in productivity, OMZ intensity and calcite dissolution in the eastern Arabian Sea
(SAGE Publications, 2014)The Oxygen Minimum Zone (OMZ) is a potential source of CO<sup>2</sup> to the atmosphere, and the extensive OMZ spread to 1.37 × 10<sup>6</sup> km<sup>2</sup> in the Northern Arabian Sea would be an important contributor ... -
Recent developments towards the synthesis of Varitriol: An antitumour agent from marine derived fungus Emericella variecolor.
(Bentham Science Publishers, 2014)Marine natural products are recognized as a fruitful source of drug development due to their rare structural entities and diverse biological activities, and consequently, publicized number of metabolites as new medicines. ... -
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ... -
Interactions of bacteria with diatoms: Influence on natural marine biofilms.
(John Wiley & Sons, 2014)Interactions between microfouling components influence the biofilm community and the cascading events, thus playing an important role in the biofouling process. Bacteria and diatoms are among the dominant forms reported ... -
A comparative study on mesozooplankton abundance and diversity between a protected and an unprotected coastal area of Andaman Islands.
(Springer, 2014)The study was carried out to understand the variability in phytoplankton production (Chlorophyll a) and mesozooplankton diversity from two different shallow coastal regions of south Andaman viz. Port Blair Bay (PBB), the ... -
Structure-function elucidation of a new alpha-Conotoxin, Lo1a, from Conus longurionis.
(American Society for Biochemistry and Molecular Biology, 2014)Alpha-Conotoxins are peptide toxins found in the venom of marine cone snails and potent antagonists of various subtypes of nicotinic acetylcholine receptors (nAChRs). nAChRs are cholinergic receptors forming ligand-gated ... -
Diversity, occurrence and socio-economic aspects of snappers and job fish (Family: Lutjanidae) fisheries from Gulf of Mannar region, south-east coast of India.
(CSIR-NISCAIR, 2014)Survey were conducted in nine fish landing centres (Pamban South, Mandapam South, Keelakarai, Ervadi, Vembar, Tharuvaikulam, Thirespuram, Tuticorin and Amalinagar) along the Gulf of Mannar region to assess the diversity, ... -
Organic enrichment and benthic fauna–Some ecological consideration.
(NISCAIR, 2014)In the present study, synoptic data on the structure of macroinfauna and total organic content of sediment collected from different sources were analyzed to look for patterns of association consistent with conceptual model ... -
Coastal circulation off Ratnagiri, west coast of India during monsoon seasons: a numerical model study.
(CSIR-NISCAIR, 2014)Present study is the coastal circulation modelling off Ratnagiri under the influence of winds and tides. A two-dimensional hydrodynamic model MIKE 21HD has been used to simulate tides and currents, and model results are ... -
Occurrence and distribution of multiple antibiotic-resistant bacteria of Enterobacteriaceae family in waters of Veraval coast, India
(University of Latvia, 2014)Current investigation was aimed to the assess occurrence and distribution of multiple antibiotic-resistant bacteria of the Enterobacteriaceae family in surface and bottom waters along the Veraval coast. Comparative prevalence ... -
Historical environmental pollution trend and ecological risk assessment of trace metals in marine sediments off Adyar estuary, Bay of Bengal, India.
(Springer, 2014)Geochemical, mineralogical and textural analyses were carried out in core sediments off Adyar estuary, Bay of Bengal, India to record the contamination trend from urban and industrial activities during the historical past. ... -
On the spatial structure and time evolution of shamal winds over the Arabian Sea – a case study through numerical modelling.
(Royal Meteorological Society, 2014)Shamal events are extra-tropical weather systems which occur in winter (cold and dry winds) as well as summer (hot and humid winds) with strong northwesterly or northerly winds blowing over the Arabian Peninsula. We have ... -
Sea breeze-induced wind sea growth in the central west coast of India.
(Elsevier, 2014)Fine resolution wind data is required in wave models to study the interaction between wind seas generated by coastal winds, and swells. In the present study, a mesoscale model, MM5, which is capable of reproducing fine ... -
Retrieval and Validation of Chlorophyll-a Concentrations in the Coastal Waters Off Yanam and Kakinada (Godavari) Basin Along East Coast of India.
(Springer, 2014)In this study chlorophyll measurements were made during March 2012 in the estuarine waters of Off Kakinada and Yanam coast, Bay of Bengal onboard a coastal vessel. In-situ water samples and optical data was collected at ... -
Characterization of phytoplankton pigments and functional community structure in the Gulf of Mannar and the Palk Bay using HPLC–CHEMTAX analysis.
(Elsevier, 2014)Phytoplankton marker pigments and their functional groups were identified for the first time in the Gulf of Mannar (GoM) and the Palk Bay (PB), located in the southeast coast of India using HPLC–CHEMTAX analytical techniques. ... -
Wave forecasting and monitoring during very severe cyclone Phailin in the Bay of Bengal.
