Lack of denitrification causes a difference in benthic foraminifera living in the oxygen deficient zones of the Bay of Bengal and the Arabian Sea
(Elsevier Ltd, 2020)
Despite being located at the same latitudes, the Bay of Bengal oxygen deficient zone (ODZ) is markedly different than the Arabian Sea ODZ. The uptake of oxygen in the Bay of Bengal does not lead to denitrification as in ...
Relict faunal testimony for sea-level fluctuations off Myanmar (Burma)
(The Palaeonlological Society of India, 2008)
The distribution and ecological significance of the relict benthic foraminiferal assemblage found in the study area off Myanmar is discussed here. Of the 126 surface sediments studied for foraminiferal content, relict ...
Assessing the effect of calcein incorporation on physiological processes of benthic foraminifera
Rosalina sp. was incubated in seawater spiked with calcein (5 mg/l to 20 mg/l calcein), a dye proposed as efficient marker to tag newly formed calcite, to understand its effect on benthic foraminifera. The experiment was ...
A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera
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 ...
Effects of sudden stress due to heavy metal mercury on benthic foraminifer Rosalina leei: Laboratory culture experiment
Laboratory culture experiments were carried out to understand the response of benthic foraminifer Rosalina leei to gradual as well as sudden addition of heavy metal mercury into the media. When mercury was added suddenly, ...
Geoscientific investigations of the seabed for paleoclimatic inferences: Thrust area for priority research in the nineties
(Geological Society Of India, 1990)
Ancient Indians (Harappan settlement) were aware of tsunami/storm protection measures: A new interpretation of thick walls at Dholavira, Gujarat, India
(Current Science Association, 2016)
Dholavira, an archaeological site of Harappan times in Gujarat, had ‘city fortification’ as a unique aspect of its town planning. The thickness of the main city wall is alarming3, 9, 10. The probable cause of such massive ...
Deterioration of Early Holocene coral reef due to sea level rise along west coast of India: Benthic foraminiferal testimony
(China University of Geosciences (Beijing), 2012)
A total of 103 surface sediment samples collected from the water depth range of 15-3300 m along Vijaydurg-Karwar stretch of central west coast of India were analyzed for foraminiferal content. Relict benthic foraminiferal ...
Distribution of benthic foraminifera within oxygen minima zone, off central west coast, India
(Gondwana Geological Society, 2003)
A total of 128 surface sediment samples (76 grab and 52 core top samples) were analyzed for benthic foraminiferal contents from the region off Goa, India in the eastern Arabian Sea upto a water depth of 3300 m. 195 species ...
Ecological response of foraminiferal component in the sediments of Kharo Creek, Kachchh (Gujarat), west coast of India
(ONGC, India, 2000)
A total of seven surface sediment samples collected within 4.4 m to 13.9 m water depth (below chart datum) from Kharo Creek were studied for their foraminiferal content. The study reveals forty seven foraminiferal species ...
