जलीय पर्यावरण पर पॊलिविनाइल क्लोराइड प्लास्टिक के प्रभाव
(National Institute of Oceanography (CSIR), India, 2012)
Impacts of Zn and Cu enrichment under ocean acidification scenario on a phytoplankton community from tropical upwelling system
Increasing dissolution of CO2 in the surface ocean is rapidly decreasing its pH and changing carbon chemistry which is further affecting marine biota in several ways. Phytoplankton response studies under the combination ...
Synthesis of Push-Pull Phenazines Possessing pH-Responsive Absorption Spectra and their Application in Selective Detection of Fe3+ Ions and Aromatics
(Georg Thieme Verlag, 2018)
Phenazines bearing electron-donor and electron-acceptor groups with high pH-sensing behavior were synthesized in moderate to good yields. Theoretical calculations on the frontier molecular orbitals and experimental oxidation ...
Intraseasonal vertical velocity variation caused by the equatorial wave in the central equatorial Indian Ocean
(American Geophysical Union, 2011)
Intraseasonal vertical velocity variation in the central equatorial Indian Ocean was investigated using observations from the field experiment "Mirai Indian Ocean Cruise for the Study of the MJO-convection Onset" and from ...
Influence of winds on temporally varying short and long period gravity waves in the near shore regions of the eastern Arabian Sea
(European Geosciences Union, 2013)
Wave data collected off Ratnagiri, west coast of India, during 1 May 2010 to 30 April 2012 are used in this study. Seasonal and annual variations in wave data controlled by the local wind system such as sea breeze and land ...
Lithospheric stretching and the long wavelength free-air gravity anomaly of the Eastern Continental margin of India and the 85 degree E Ridge, Bay of Bengal
Among the submarine ridge systems in the northern Indian Ocean, the 85 degree E Ridge in the Bay of Bengal is more enigmatic owing to its peculiar anomalous negative free-air gravity. In general, this has been attributed ...
Marine archaeological investigations along the Saurashtra coast, west coast of India
(Asiatic Society of Bangladesh, 2005)
Utilization of the ocean resources on the Saurashtra coast is dating back to the Harappan period (3rd millennium BC) and evidences on the same have been recorded from various archaeological sites such as Lothal, Padri, ...
Sedimentary organic matter composition from tropical ports with distinct geographic and morpho-hydrodynamic characteristics: Evaluation through multiple biochemical markers
(Elsevier Ltd, 2020)
Increasing coastal urbanization and shipping activity-related environmental pollution advocate the importance of assessment of port ecosystems. Fatty acid biomarkers, elemental components, and biopolymers were used to ...
Exploration and excavation of shipwrecks in Goa and adjoining waters 2005-2006
(NIO, India, 2006)
As a part of the institutional project, 'Application of Geological and Geophysical methods in Marine Archaeology and Underwater Explorations, (OLP 0008)', exploration and excavation of shipwrecks have been carried out from ...
Denitrification exceeds anammox as a nitrogen loss pathway in the Arabian Sea oxygen minimum zone
The oxygen minimum zones (OMZs) of the world oceans are sites of enhanced anaerobic nitrogen transformations, such that the largest OMZ, the Arabian Sea, is responsible for 30-50% of the oceanic water column fixed N loss. ...
