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, ...

Effect of temperature and salinity on stable isotopic composition of shallow water benthic foraminifera: A laboratory culture study
(Bengaluru: Geological Society of India, 2013)
Quantitative estimation of past climatic parameters from stable isotopic composition of foraminifera relies on estimating the precise relationship between stable isotopic composition of the species analyzed and the ...
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 ...
