A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera
(AGU, 2005)Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last approx. 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record ... -
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 ... -
Clay minerals as palaeomonsoon proxies: Evaluation and relevance to the late Quaternary records from SE Arabian Sea
(NCAOR, Goa, 2005)Palaeoclimatic studies are largely dependent on the quality of records and a prudent use of environmental proxy indicators. In this study, the factors affecting the detrital clay minerals in marine environment and their ... -
Constraints in using Cerium-animaly of bulk sediments as an indicator of paleo bottom water redox environment: A case study from the Central Indian Ocean Basin
(Elsevier, 2005)The total rare earth elements (Sigma REE) abundance along with major and a range of trace element chemistry of twenty-eight sub-sections in a 5 m long sediment core (AAS-05/GC-02) from the Central Indian Ocean Basin shows ... -
Effect of river discharge on the morphology of benthic foraminiferal test
(Geological Society of India, 1994)Twenty one surface sediment samples collected from the inner shelf region off Karwar at 22-52 m water depth range have been studied for foraminiferal content. Based on the external test morphology the entire foraminiferal ... -
Organic enrichment and benthic fauna–Some ecological consideration.
(NISCAIR, 2014)In the present study, synoptic data on the structure of macroinfauna and total organic content of sediment collected from different sources were analyzed to look for patterns of association consistent with conceptual model ... -

Productivity fluctuations in the southeastern Arabian Sea during the last 140 ka
(Elsevier, 2003)Detailed analyses of multiple geochemical productivity proxies such as calcium carbonate, biogenic opal, biogenic Ba, organic carbon and total nitrogen have been carried out on a sediment core from the southeastern Arabian ... -
Rapid climatic shifts and its influence on ancient civilisations: Evidence from marine records
(Universities Press, Hyderabad, India, 1998)The southwest (SW) monsoon system in the Arabian Sea exerts a strong influence upon the climatic conditions in South and Southeast Asia and the associated monsoon rainfall has a great impact on the socio-economic and ... -
Stone anchors (composite type) from the Saurshtra coast, India: An indicator of ancient ports and sea routes
(The Australasian Institute for Maritime Archaeology, 2004)Marine archaeological investigations on the Saurashtra coast specially at Dwarka, Bet Dwarka, Armada and Somnath brought to light a large number of stone anchors of various type which include composite, grapnel and ring-stone ...
