Precambrian mega lineaments across the Indian sub-continent - Preliminary evidence from offshore magnetic data
(Indian Academy of Sciences, 2006)Marine and airborne magnetic data over south Indian continent including the western and eastern continental margins between latitudes 12°30`N and 10°N were studied and interpreted. The total intensity magnetic anomalies ... -
Atmospheric forcing on the seasonal variability of sea level at Cochin, southwest coast of India
(Elsevier, 2006)The seasonal cycles of some atmospheric parameters at Cochin (southwest coast of India) have been studied with a specific emphasis on the role played by them in forcing the seasonal sea level. Equatorward along-shore wind ... -
Imaging trench-line disruptions: Swath mapping of subduction zone
(Indian Academy of Sciences, 2006)Analogous to other subduction zones in the world where the heavier oceanic plate shoves below the lighter continental plate, crustal movement along the Sumatra–Andaman trench line over the last two centuries released ... -
Potential of autonomous underwater vehicles as new generation ocean data platforms
(Indian Academy of Sciences, 2006)This article introduces the reader to a new generation of ocean data platforms known as Autonomous Underwater Vehicles (or AUVs) brought about by promising technology developments in new sensors, memories, embedded controllers ... -
Trace Metals And Organic Matter Diagenesis At The Oman Margin
(1997)Trace Metals (e.g. Mn and Fe) play an important role as secondary oxidants in the degradation of sedimentary OM under sub-oxic conditions. Hence the remineralisation of organic constituents of sediments in the marine ... -
Marine archaeological explorations in the Kaveripoompattinam regions: Fresh light on the structural remains
(Indian Society for Prehistoric and Quaternary Studies, 1996)Kaveripoompattinam also known as Poompuhar, was a port which played an important role in the maritime history of India. Archaeological findings, and inscriptional as well as literary evidence bear ample testimony to this. ... -
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 ... -
