Genotoxicity of cadmium in marine diatom Chaetoceros tenuissimus using the alkaline Comet assay
(Springer, 2006)Genotoxic effects of Cadmium on phytoplankton Chaetoceros tenuissimus have been evaluated using DNA damage by comet assay. Cadmium concentrations ranging from 2.4 to 10 mg/L were used to evaluate the effects. Results showed ... -
Onshore and nearshore explorations along the Maharashtra Coast: With a view to locating ancient ports and submerged sites
(Indian Society for Prehistoric and Quaternary Studies, 1997)Coastal explorations were carried out along the west coast of India at Elephanta Island, Malvan, Vijaydurg, Sopara and Chaul. A number of lead and copper coins as well as pottery of different cultural periods were found. ... -
Early maritime activities of Orissa on the east coast of India: Linkages in trade and cultural development
(Indian Society for Prehistoric and Quaternary Studies, 2002)In the maritime history of India, Orissa (ancient Kalinga) played a significant role in spreading Indian culture to other parts of the world, including Africa, Rome and Southwest Asia. Archaeological findings, explorations ... -
The Late-Pleistocene sedimentation history in the Eastern Arabian Sea: Climate Weathering-Productivity linkage
(2004)This thesis is aimed to understand the response of the Indian monsoons and associated biogeochemical processes in the Eastern Arabian Sea (EAS) to the past climate change. The EAS bordering the western coast of India is ... -
Seasonal variability of mixed layer in the central Arabian Sea and its implication on nutrients and primary productivity
(Elsevier, 2005)The upper layers of the ocean play an important role in the regulation of the ocean-atmosphere as a coupled system. The Arabian Sea, situated in the western part of the northern Indian Ocean, participates in the intense ... -
Maritime History of Andhra Pradesh and Prospects for Marine Archaeological Research
(Sarada Publishing House, New Delhi, 2006)Archaeological, epigraphical, numismatic and other sources confirm that similar to ports in other coastal states of India, the ports of Andhra Pradesh had played a significant role in spreading Indian culture overseas to ... -
Study of the directional spectrum of ocean waves using array, buoy and radar measurements
(1999)Phase/time/path difference (PTPD) methods of Esteva [1977] and Borgman [1974] with two modifications, viz., true phase and coherence proposed in this thesis, have for the first time been successfully used for computing ... -
Amino sugars in suspended particulate matter from the Bay of Bengal during the summer monsoon of 2001
(Indian Academy of Sciences, 2006)Amino sugars (AS)are important constituents of organic matter.However,very little is known about their cycling in marine waters.In this research,we assessed the distribution and cycling of these compounds in waters of the ... -
Reaction of Elemol with Acetic acid –Perchloric acid: Characterization of a novel oxide and (+)-β-cyperone
(Springer-Verlag, 2006)The minor unidentified compounds of acetic acid- perchloric acid dehydration of elemol (1) have been fully characterized. The structure and relative stereochemistry as shown in (2) of the less polar fragrant compound named ... -
Imprints of Chilika Lake in the offshore region – A geomorphologic evidence
(Indian Academy of Sciences, 2006)Chilika Lake (Orissa, India) is the largest lagoon in the subcontinent along the east coast of India, situated between latitudes 19 degrees 28’ and 19 degrees 54’ N and longitudes 85 degrees 05’ and 85 degrees 38’ E. In ... -
Influence of northeasterly trade winds on intensity of winter bloom in the northern Arabian Sea
(Indian Academy of Sciences, 2006)Chlorophyll and wind pattern retrieved from remote sensing data have been used to study biological activity in the oceanic waters of Northern Arabian Sea (NAS) during February–March 2002–05. Occurrence of algal bloom in ... -
Factors guiding tsunami surge at the Nagapattinam–Cuddalore shelf, Tamil Nadu, east coast of India
(Indian Academy of Sciences, 2006)The Tamil Nadu margin, in particular the Nagapattinam–Cuddalore shelf was the worst affected by the tsunami surge and inundation caused by the great Sumatra earthquake of 26 December 2004 (Mw 9.3). Surge heights in this ... -
The great tsunami of 26 December 2004: A description based on tide gauge data from Indian subcontinent and surrounding areas
(Terrapub, 2006)The Great Tsunami of 26 December 2004 is described using data from seven tide gauges in India and others from surrounding areas in the Indian Ocean. The tsunami struck the Indian east coast around 0330 UTC. The amplitude ... -
Deep-sea fungi as a source of alkaline and cold-tolerant proteases
(Elsevier, 2006)Fungi from coastal environments have been widely studied with respect to the production of secondary metabolites and biotechnologically useful lignocellulolytic enzymes. A few studies on mycology of deep-sea sediments, ... -
Purification and characterization of thermoalkalophilic xylanase isolated from the Enterobacter sp. MTCC 5112
(Elsevier, 2006)Thermoalkalophilic Enterobacter sp MTCC 5112 was isolated from a sediment sample collected from the Mandovi estuary, west coat of India. This culture produced extracellular xylanase. The xylanase enzyme was isolated by ... -
Pink-line syndrome, a physiological crisis in the scleractinian coral Porites lutea
(Springer-Verlag, 2006)Coral diseases are one of the major factors that alter coral cover and their diversity. We have earlier reported the “Pink-line syndrome” (PLS) in the scleractinian coral Porites lutea wherein a colored band appears between ... -
Are eddies nature’s trigger to enhance biological productivity in the Bay of Bengal?
(American Geophysical Union, 2004)The Bay of Bengal is traditionally considered to be a less productive basin compared to the Arabian Sea. Despite the contrasting chlorophyll and primary productivity pattern, sediment trap data shows that annual fluxes of ... -
Increased formation of carcinogenic PAH metabolites in fish promoted by nitrite
(Elsevier, 2006)Nitrite (NO2−), a highly reactive chemical species, accumulates in coastal waters as a result of pollution with nitrogenous waste and/or an imbalance in the bacterial processes of nitrification and denitrification. The ... -
Why is the Bay of Bengal less productive during summer monsoon compared to the Arabian Sea?
(American Geophysical Union, 2002)The Bay of Bengal is traditionally considered to be a less productive basin compared to the Arabian Sea. We explore the reasons for this in the central Bay during summer when both are subjected to strong monsoon forcing. ... -
Intrusion of the Bay of Bengal water into the Arabian Sea during winter monsoon and associated chemical and biological response
(American Geophysical Union, 2004)Situated in similar latitudes and subjected to similar atmospheric forcing, the tropical basins of the Arabian Sea looses fresh water due to excess evaporation over precipitation while Bay of Bengal receives freshwater via ...
