Regeneration and abnormality in benthic foraminifer Rosalina leei: Implications in reconstructing past salinity changes
(Universita' degli Studi di Milano, 2011)
A laboratory culture experiment has been conducted to assess the response of marginal marine benthic foraminifer Rosalina leei to salinity and associated pH changes. Live specimens of Rosalina leei were subjected to a range ...
Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary.
(European Geosciences Union, 2014)
The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. ...
Effect of salinity induced pH/alkalinity changes on benthic foraminifera: A laboratory culture experiment
(Elsevier, 2015)
The salinity of coastal waters in the vicinity of seasonally fresh water fed estuaries changes tremendously and reportedly affects the living calcite secreting organisms like foraminifera, as well as their dead remains. ...
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 ...
Assessing the effect of calcein incorporation on physiological processes of benthic foraminifera
(Elsevier, 2015)
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
(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 ...
Effects of sudden stress due to heavy metal mercury on benthic foraminifer Rosalina leei: Laboratory culture experiment
(Elsevier, 2009)
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, ...
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 ...
Appraisal of laboratory culture experiments on benthic foraminifera to assess/develop paleoceanographic proxies
(NISCAIR, CSIR, 2007)
The laboratory culture studies, carried out on benthic foraminifera, with the aim to refine paleoceanographic / paleoclimatic or environmental application of benthic foraminifera, have been reviewed. The review includes ...
Palaeoceanographic implications of abundance and mean proloculus diameter of benthic foraminiferal species Epistominella exigua in sub-surface sediments from distal Bay of Bengal fan
(Indian Academy of Sciences, 2005)
Temporal variation in abundance and mean proloculus diameter of the benthic foraminiferal species Epistominella exigua has been reconstructed over the last approx. 50,000 yr BP, from a core collected from the distal Bay ...
