An aberrant Bulimina species from recent sediments off Karwar, West Coast of India
(Nav Jyoti, India, 1990)A case of abnormal two apertured Bulimina species was encountered in a sea bottom sample from 24 metre water depth off Karwar. This abnormality seems to be a case of regeneration/repair -
Cyclicity in the Late Holocene monsoonal changes from the western Bay of Bengal: Foraminiferal approach.
(The Palaeontological Society of India, 2009)Benthic foraminiferal characteristics, including abundance of total benthic foraminifera, angular asymmetrical benthic foraminifera, Uvigerina sp. and Bulimina marginata, have been studied in a piston core (exihibiting ... -
Evidences of climatic variations during Late Pleistocene- Holocene in the eastern Bay of Bengal
(Current Science Association, Bangalore, India, 1993)Based upon the variations of clay minerals, sediment texture, heavy mineral assemblage and sup(230)Th excess in the Late Pleistocene sediments of a hemipelagic core from the eastern Bay of Bengal (2713 m water depth), 35 ... -
High resolution climatic records of the past ~489 years from Central Asia as derived from benthic foraminiferal species, Asterorotalia trispinosa
(Elsevier, 2012)Many researchers have reported the occurrence of the species Asterorotalia trispinosa as a major constituent in foraminiferal assemblages from different regions, its ecological significance has never been studied. The ... -
Holocene marine transgression as interpreted from bathymetry and sand grain size parameters off Gopalpur
(Indian Academy of Sciences, Bangalore, 1989)Grain size statistical parameters of the surface sediment samples collected from the innershelf off Gopalpur were calculated using graphic and moment methods. Fine-grained sand present up to 15 m water depth shows symmetrical ... -
Holocene sea level fluctuations on western Indian continental margin: An update
(Geological Society of India, 1995)A new Holocene curve is generated for the western Indian continental margin. While constructing this curve careful selection of the dates were made by giving due considerations to the genetic characteristics of the dated ... -
Holocene sea levels of Visakhapatnam shelf, east coast of India
(Geological Society of India, 1994)The Holocene sea level changes in the shelf areas off Visakhapatnam was studied from sediment distribution pattern and shallow seismic profiling. Morphological features on the shelf indicate a Late Pleistocene regression ... -
Paired measurements of foraminiferal delta 18 O and Mg/Ca ratios of Indian monsoons reconstructed from Holocene to Last Glacial record
(Geological Society of China, 2011)The effect of seasonally reversing monsoons in the northern Indian Ocean is to impart significant changes in surface salinity (SS). Here, we report SS changes during the last 32 kyr in the Lakshadweep Sea (southeastern ... -
Planktonic foraminifera from core tops of western equatorial Indian Ocean
(Calcutta: Geological Survey of India, 1989)A set of seven core tops from western equatorial Indian ocean were analysed for planktonic foraminifera, which has yielded 20 planktonic foraminiferal species. Among them Globorotalia menardii, Globigerinoides sacculifer ...
