1300 km long late Pleistocene-Holocene shelf edge barrier reef system along the western continental shelf of India: Occurrence and significance
(Elsevier, 1996)A detailed analysis of echosounding and side-scan sonar data collected from the western continental margin of India has revealed the presence of prominent shelf edge reefs, concentrated mostly on the central and the southern ... -
A review on Holocene climate changes in Indian subcontinent
(Geological Society of India, 1999)Since the collision of Indian plate with Eurasia, the Indian subcontinent has experienced minor tectonic and major climatic changes. Summer monsoon plays an important role in the local and regional climate of Asia. General ... -
Atypical delta sup(13) C signature in Globigerina bulloides at the ODP site 723A (Arabian Sea): Implications of environmental changes caused by upwelling
(Elsevier, 2004)Production of Globigerina bulloides generally increases during upwelling in the tropical ocean and, in particular, during southwest monsoon season in the Arabian Sea. We studied the delta sup(13) C signatures of Globigerina ... -
Carbonate mineralogy and faunal relationship in tropical shallow water marine sediments: Cape Comorin, India
(Elsevier, 1982)The carbonate mineralogy of Recent sediments from the western and eastern continental shelves around Cape Comorin off the southern tip of India was determined by X-ray diffraction analyses. The results show that in the ... -
Equatorial Indian Ocean productivity during the last 33 kyr and possible linkage to Westerly Jet variability
(Elsevier, 2014)The top 1 m radiocarbon dated section of a 5.6 m long sediment core retrieved from the Equatorial Indian Ocean is studied for productivity changes in response to climate variability that have taken place during the last ... -
Foraminifera in surface sediments of Mandovi River Estuary: Indicators for mining pollution and high sea stand in Goa, India
(Coastal Education and Research Foundation, 2005)Foraminiferal characteristics of 11 surface sediment samples collected from the Mandovi estuary during 2001 have been compared with similar data based on samples collected during 1994. The study reveals drastic fall in ... -
Glacial to Holocene fluctuations in hydrography and productivity along the southwestern continental margin of India
(Elsevier, 2001)Oxygen isotope and sedimentological records of a sediment core from the southwestern continental margin of India are used to reconstruct the fluctuations in sea surface hydrography and productivity during the last deglaciation. ... -
Holocene benthonic foraminifera from the shelf sediments of Kerala coast
(Indian Society of Earth Scientists, 1974)Of the 32 species of benthic foraminifera recovered here some show definite Indo-Pacific affinity. Ecological parameters which govern this offshore region are considered. Several species show similarities with those found ... -
Holocene limestones of part of the western continental shelf of India
(Geological Society of India, 1979)Dredging on the western continental shelf of India has shown that the most common rock types outcropping on the irregular topography of the outer shelf (70-90 m) are algal limestones and shelly limestones containing ... -
Holocene phosphorites of the western continental margin of India
(Indian Association for Limnology and Oceanography, 1985)Seventeen samples collected during different cruises of RV Gaveshani, were analysed by X-Ray diffractometer for apatite. These samples consists of algal and oolitic limestones and were recovered from depths ranging from ... -
Holocene planktonic foraminifera from the shelf sediments off Kerala Coast
(Geological Society of India, 1972)Twenty-two planktonic foraminifers were identified from a few samples collected aboard INS KISTNA at 9~'N and 76~'E, at 89 metres depth from the bottom sediment-water interface. A few of the more characteristic features ... -
Holocene submarine terraces on the western continental shelf of India; implications for sea-level changes
(Elsevier, 1994)Detailed echosounding, side-scan sonar and high-resolution seismic-reflection profiling on the western continental shelf of India have revealed a series of submarine terraces at different depths between the outer fringe ... -
Indian summer monsoon variability during the Holocene as recorded in sediments of the Arabian Sea: Timing and implications
(TERRAPUB, 2007)Indian monsoon precipitation fluctuated significantly during the Holocene and a reliable reconstruction of the timing of the events and their implications is of great benefit to our understanding of the effect and response ... -
Influences of Holocene sea level, regional tectonics, and fluvial, gravity and slope currents induced sedimentation on the regional geomorphology of the continental slope off northwestern India
(Elsevier, 1993)Regional geomorphology derived from echosounding and bathymetric data (lines of a total of 12,000 km), depth to basement, regional deep seated tectonic features, surficial sediment distribution and Holocene sedimentation ... -
Lithogenic fluxes to the northern Indian Ocean - An overview
(University of Hamburg, Germany, 1993)Lithogenic fluxes to the northern Indian Ocean, measurEd. by time-series sediment traps, exhibit a strong seasonality with the bulk of the material (40 to 80 %) being deposited during the southwest monsoon period. This ... -
Monsoon related changes in sea surface productivity and water column denitrification in the Eastern Arabian Sea during the last glacial cycle
(Elsevier, 2005)Sea surface salinity reconstruction for the Holocene and the Last Glacial Maximum (LGM) suggests that the LGM-Eastern Arabian Sea was more saline (by approx.5 psu) than the Holocene due to weakened freshwater flux to the ... -
Postglacial Indian Ocean

Seasonal sea surface temperature contrast between the Holocene and last glacial period in the western Arabian Sea (Ocean Drilling Project Site 723A): Modulated by monsoon upwelling
(AGU, 2005)Annual, summer, and winter sea surface temperatures (SSTs) in the western Arabian Sea were reconstructed through the last 22 kyr using artificial neural networks (ANNs) based on quantitative analyses of planktic foraminifera. ... -
Slumping on the western continental margin of India
(Asociacion Argentina de Geofisicos y Geodestas, 2001)A short gravity core from the Western Continental Margin of India has been examined to understand the nature and characteristics of slumping in the area. The present study and also the earlier studies revealed that the ... -
