Biomarkers of petroleum contamination in the digestive gland of Perna viridis (L.)
(The Scientific and Technological Research Council of Turkey, 2012)Oxidative stress responses were evaluated in the digestive gland tissue of Perna viridis exposed to water accommodated fractions (WAFs) of petrol and diesel at 0.5 percent and 5 percent concentrations over 5-, 10-, and ... -
A deductive approach to select or rank journals in multifaceted subject, Oceanography
(Springer, 2012)This study discusses Singleton approach and differential approach for analyzing citations of published literature in oceanography from 30 countries. The ranking correlation of journals showed better positive correlation ... -
Making sense of ocean biota: How evolution and biodiversity of land organisms differ from that of the plankton
(Indian Academy of Sciences, 2012)The oceans cover 70% of the planet’s surface, and their planktonic inhabitants generate about half the global primary production, thereby playing a key role in modulating planetary climate via the carbon cycle. The ocean ... -
Toxic metals enrichment in the surficial sediments of a eutrophic tropical estuary (Cochin Backwaters, Southwest coast of India)
(The Scientific World Journal, 2012)Concentrations and distributions of trace metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in surficial sediments of the Cochin backwaters were studied during both monsoon and pre-monsoon periods. Spatial variations were ... -
Antarctic climate variability during the past few centuries based on ice core records from coastal Dronning Maud Land and its implications on the Recent warming
(Springer-Verlag, 2012)Analysis of the available instrumental records revealed that Antarctica has undergone complex and significant temperature changes during the recent decades, with a substantial warming in most parts of the West Antarctica ... -
Algal blooms: a perspective from the coasts of India
(Springer, 2012)Algal blooms have been documented along the west and east coasts of India. A review of bloom occurrences in Indian waters from 1908 to 2009 points out that a total of 101 cases have been reported. A comparison of the bloom ... -
Marine microbial ecology: Reminiscence of the status and some suggestions for the way forward
(CUSAT; India, 2012)An attempt has been made to pick out a few aspects of the vast progress that the science of marine microbial ecology has made in the recent years and how we can move forward notwithstanding the challenges. -
Pyrrolizidine alkaloids pyrrolams A-D: A survey of synthetic efforts, biological activity, and studies on their stability
(Georg Thieme Verlag KG, 2012)Pyrrolam A is a microbial metabolite, structurally related to plant alkaloids of the necine-type, and was isolated from the bacterial strain of Streptomyces olivaceus along with the related alkaloids pyrrolams B-D. The ... -
Bio-physical coupling and ocean dynamics in the central equatorial Indian Ocean during 2006 Indian Ocean Dipole
(American Geophysical Union, 2012)The high-frequency times-series data collected during 28th October to 21st November 2006 onboard R/V Mirai provided the first evidence of short-term bio-physical coupling in the central equatorial Indian Ocean (EIO). The ... -
Chemistry of the nudibranch Aldisa andersoni: Structure and biological activity of phorbazole metabolites
(MDPI Publishing, 2012)A chemical study of the Indo-Pacific dorid nudibranch Aldisa andersoni resulted in the isolation of five chlorinated phenyl-pyrrolyloxazoles belonging to the phorbazole series. Two new molecules, 9-chloro-phorbazole D and ... -
Tracking the history of dinoflagellate cyst assemblages in sediments from the west coast of India
(Elsevier, 2012)In order to trace the history of dinoflagellate cyst assemblages and provide new insights in to Harmful Algal Bloom (HAB) dynamics in monsoon influenced tropical environments, sediment cores were collected from four different ... -
Residence time of pollutants discharged in the Gulf of Kachchh, northwestern Arabian Sea
(Elsevier, 2012)A 2D Hydrodynamic-Particle Analysis model was applied to the Gulf of Kachchh (GoK) to estimate the residence time of pollutants. The tidal currents in the Gulf have a strong E-W component, which prevents the material in ... -
Shivajiella indica gen. nov., sp. nov., a marine bacterium of the family "Cyclobacteriaceae" with nitrate reducing activity
(Elsevier, 2012)Novel orange pigmented, Gram-negative-staining, rod-shaped, non-motile, strictly aerobic strains designated NIO-S1 sup(T) and NIO-S2 were isolated from the water sample of a pond adjacent to the coast and an algal mat from ... -
Identifying the related compounds using electrospray ionization tandem mass spectrometry: bromotyrosine alkaloids from marine sponge Psammaplysilla purpurea
(IM Publications, 2012)We have investigated extracts of marine sponge Psammaplysilla purpurea during three collections from Mandapam (Tamil Nadu, India) and Okha (Gujarat, India) and indentified two new bromotyrosine alkaloids, purpurealidin I ... -
Studies on phytoplankton with reference to dinoflagellates
(2010)This study was carried out to analyze the spatio-temporal variations in phytoplankton communities in the open ocean using the ‘ships of-opportunity’ programme. Considering the limitations of microscopic methods,pigment ... -
Studies on phytoplankton-bacterial interactions
(2010)Given the sheer range of phytoplankton-bacterial interactions, some intriguing aspects have been addressed in this study. Firstly, the role of bacteria in influencing phytoplankton communities at the system level was ... -
