Glacial-interglacial changes in the surface water characteristics of the Andaman Sea: Evidence from stable isotopic ratios of planktonic foraminifera
(Indian Academy of Sciences, 2000)Stable carbon and oxygen isotopic analyses of the planktonic foraminifera (Globigerinoides ruber) from a deep sea sediment core (GC-1) in the Andaman Sea show high glacial-to-Holocene d<sup>18</sup>O amplitude of 2.1% which ... -
Glacial-interglacial contrast in deep-water δ13C of the Arabian Sea
(Springer, 2022)Carbon and oxygen isotopic ratios of foraminiferal test are exclusively used for tracing the past changes in ocean circulation, air-sea exchange, global carbon cycle and temperature variations of water masses. Here we ... -
Glacial-interglacial contrasts revealed by n-alkanes in sediments of the Equatorial Indian Ocean during the last 300,000 years
(Elsevier, 2017)A sediment core aged up to 300 kyr from the Equatorial Indian Ocean (EIO) was examined for its inorganic and organic geochemistry, the objective being to identify coherent markers of glacial-interglacial changes and ... -
Glacial-interglacial differences in carbonate burial in the equatorial Indian Ocean
(Springer, 2022)To understand the variations in carbonate burial for the last 30 kiloannum (ka), we have utilized a core from the Ocean Drilling Program (ODP), Site716A (04.56�N and 73.17�E) retrieved from a water depth of 533~m from the ... -
Glacially derived material in an Inner Mongolian desert lake during Marine Isotope Stage 2
(John Wiley, 2012)Establishing the precise timing of continental glacial dynamics and abrupt high-latitude climate events is crucial to understanding the causes of global climate change. Multi-proxy records in a lake sediment core from arid ... -
Glass and mineral chemistry of northern central Indian ridge basalts: Compositional diversity and petrogenetic significance
(The Geological Society of China, 2009)The glass and mineral chemistry of basalts examined from the northern central Indian ridge (NCIR) provides an insight into magma genesis around the vicinity of two transform faults: Vityaz (VT) and Vema (VM). The studied ... -
Glass spherules from Antarctica blue ice and deep-sea sediment of the Central Indian Ocean Basin
(Springer, 2021)We report the chemical composition of 176 glass spherules obtained from Antarctica blue ice and deep-sea sediments from the Central Indian Ocean Basin. This study compares the chemistry of glass spherules collected from ... -

Global assessment of tropical cyclone intensity statistical-dynamical hindcasts
(Wiley, 2017)This paper assesses the characteristics of linear statistical models developed for tropical cyclone (TC) intensity prediction at global scale. To that end, multilinear regression models are developed separately for each ... -
Global Carbon Cycling on a Heterogeneous Seafloor.
(Elsevier, 2018)Diverse biological communities mediate the transformation, transport, and storage of elements fundamental to life on Earth, including carbon, nitrogen, and oxygen. However, global biogeochemical model outcomes can vary by ... -
Global concerns of ship`s ballast water mediated translocation of bacteria
(Springer and Business Media, 2017)Shipping facilitates transportation of over 90% of the world’s commodities and eventually transfers ~10 billion tons of ballast water which is routinely taken aboard vessels to maintain their stability. The ballast water ... -
Global equatorial sea-surface temperatures over the last 150,000 years: An update from foraminiferal elemental analysis
(Current Science Association, 2011)Solar insolation changes are amongst various factors that affect sea-surface temperature (SST) which in turn modulate global climate. Out of all the oceanic regions, equatorial region receives the maximum solar insolation ... -

Global impact of tropical cyclones on primary production
(John Wiley & Sons, Ltd, 2016)In this paper, we explore the global responses of surface temperature, chlorophyll, and primary production to tropical cyclones (TCs). Those ocean responses are first characterized from the statistical analysis of satellite ... -
Global patterns and predictions of seafloor biomass using random forests
(Public Library of Science, 2010)A comprehensive seafloor biomass and abundance database has been constructed from 24 oceanographic institutions worldwide within the Census of Marine Life (CoML) field projects. The machine-learning algorithm, Random ... -
Global warming and coral reefs
(Tamil Univ., 1990)Ever increasing global warming trend is predicted to cause within the next 100 years an accelerated sea level rise, increase in sea surface temparature and enhanced ultraviolet radiation to a significant enough extent to ... -
Globigerina pachyderma (Ehrenberg) in the shelf-slope sediments of northern Indian Ocean
(1974)The occurrence of specimens of @iGlobigerina pachyderma@@ (Ehrenberg) which is considered to be a typical bipolar, cooler water species, in the Recent shelf-slope sediments of the northern Indian Ocean as far north as 9, ...
