Evidence for seafloor spreading in the Laxmi Basin, northeastern Arabian Sea
(Elsevier, 1994)Marine magnetic anomaly data from the Laxmi Basin for the first time reveal the presence of fairly correlatable NNW-trending magnetic lineations. These magnetic lineations are symmetric about a central negative magnetic ... -
Evidence for the existence of Persian Gulf water and Red Sea water in the Bay of Bengal
(Springer, 2017)The high-salinity water masses that originate in the North Indian Ocean are Arabian Sea High-Salinity Water (ASHSW), Persian Gulf Water (PGW), and Red Sea Water (RSW). Among them, only ASHSW has been shown to exist in the ... -
Evidence for the formation of different-sized nodules by different accretionary processes
(Taylor and Francis, 1993)Studies on different-sized polymetallic nodules from the Central Indian Ocean Basin reveal that chemical composition is largely related to the nodule diameter which show systematic decrease in Mn, Cu, and Ni content with ... -
Evidence for underwater current activity on the upper slope of the carbonate platform off western India using multibeam bathymetry
(Current Science Association & Indian Academy of Sciences, 2019)This note presents multi-beam bathymetry data from the carbonate platform on the outer continental shelf of the northwestern margin of India at water depths between 60 and 90 m. This study analyze effect of underwater ... -
Evidence of binary division in mature central capsules of a collosphaerid colonial radiolarian: Implications for shell ontogenetic patterns in modern and fossil species
(Coquina Press, 1998)Evidence is presented from fossil shells and living species of the colonial radiolarian Acrosphaera that maturer central capsules with shells can produce daughter central capsules and shells by binary fission. These data ... -
Evidence of climatic change during Holocene in the nearshore regions of Konkan (central west coast of India
(Museo Geologico di Bologna, 1993)In order to understand the paleoenvironmental setting of the nearshore area of the central west coast of India, three vibro-cores from the Kalbadevi Bay, from a depth range of 6-12 m were analysed for sedimentological, ... -
Evidence of fault reactivation off Pondicherry coast from marine geophysical data
(Indian Academy of Sciences, 2002)The present study mainly focuses on the northern part of the Cauvery offshore basin, between latitudes 10 degrees and 14 degrees N, and longitudes 80 degrees and 82 degrees E, over which the bathymetry, gravity and magnetic ... -
Evidence of Himalayan erosional event at approx. 0.5 Ma from a sediment core from the equatorial Indian Ocean in the vicinityof ODP Leg 116 sites
(Elsevier, 2005)A sediment core collected from an area _100 miles south of the ODP Leg 116 (distal Bengal Fan) in the equatorial Indian Ocean was investigated for microfossils, mineralogy, mineral chemistry, magnetic susceptibility, grain ... -
Evidence of paleo-cold seep activity from the Bay of Bengal, offshore India
(American Geophysical Union, 2009)Evidence of paleo–cold seep associated activities, preserved in methane-derived carbonates in association with chemosynthetic clams (Calyptogena sp.) from a sediment core in the Krishna-Godavari basin, Bay of Bengal is ... -
Evidence of shoreline shift on the northern Saurashtra coast: Study based on the submerged temple complex at Pindara
(Indian Academy of Sciences, 2007)Shoreline changes have played a vital role in emergence and devolution of any civilization along the coast. An onshore exploration on the northwestern coast of the Saurashtra, Gujarat, India brought to light the remains ... -
Evidence of slumping/sliding in Krishna-Godavari offshore basin due to gas/fluid movements
(Elsevier, 2011)The Krishna-Godavari (KG) offshore basin is one of the promising petroliferous basins of the eastern continental margin of India. Drilling in this basin proved the presence of gas hydrate deposits in the shallow marine ... -
Evidence of soil microplastics inhibiting the germination of commercial coriander seeds under field conditions
(Springer; Institute for Ionics, 2023)The environmental impacts of microplastics (MPs) and nanoplastics (NPs), and their occurrence in aquatic, terrestrial, and aerial biomes have engrossed global attention. Most impact assessment studies have majorly linked ... -
Evidences for a volcanic province in the Central Indian Basin
(Geological Society of India, 1995)Based on various lines of evidence such as the widespread occurrence of basalts, pumice, volcanic glass shards and their transformational products (zeolites, palagonites, and smectite-rich sediments), we suggest the presence ... -
Evidences for incipient hydrothermal event(s) in the Central Indian Basin: A review
(The Geological Society of China, 2005)The Central Indian Basin (CIB, 10 degrees-19 degrees S) encompasses morphotectonic features such as seamounts, abyssal hills, faults, fracture zones and lineations and basic to silicic volcanics that were derived from ... -
Evidences for seawater-rock hydrothermal interaction in the serpentinites from Northern Central Indian Ridge
(Current Science Association, 2009)Serpentinites and serpentinized harzburgites were collected from a ridge-transform intersection at 6 ddgrees 39 minutes S-68 degrees 19 minutes E from the Northern Central Indian Ridge. The degree of serpentinization is ... -
Evidences of climatic variations during Late Pleistocene- Holocene in the eastern Bay of Bengal
(Current Science Association, Bangalore, India, 1993)Based upon the variations of clay minerals, sediment texture, heavy mineral assemblage and sup(230)Th excess in the Late Pleistocene sediments of a hemipelagic core from the eastern Bay of Bengal (2713 m water depth), 35 ... -
Evidences of CO2 Leakage During the Last Deglaciation: The Need to Understand Deep-ocean Carbonate Chemistry of the Arabian Sea
(Geological Society of India, India, 2018)It is generally accepted view that the ventilation of Southern Ocean during the last deglaciation was the key factor in atmospheric CO2 rise. Further, other sites were identified, like the western equatorial Pacific, the ... -
