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 ...
Marine geophysical studies off Karwar, West Coast of India
(Geological Society of India, 1989)
Geophysical studies of the southwestern continental margin revealed significant surface and subsurface topographic highs (ridges) trending NNW-SSE to NW-Se beyond the shelf break. Residual magnetic anomaly map depicts ...
Effect of sediment-water interface 'boundary layer' on exposure of nodules and their abundance: a study from seabed photos
(Geological Society of India, 1989)
The results obtained from seabed photos and boomerang grab samples reveal a striking similarity in distribution patterns of size classes of polymetallic nodules. Due to partial sediment cover, there is a 'fractionation' ...
Magnetic lineations in the Central Indian Basin for the period A24-A21: a study in relation to the Indian Ocean Triple junction trace
(Elsevier, 1989)
A detailed study of magnetics and bathymetry was carried out in the Central Indian Basin between latitudes 9 degrees S and 16 degrees 30'E and longitudes 73 degrees E and 79 degrees 30'E. The observed east-west trending ...
Grade distributions in manganese nodules of Central Indian Ocean Basin
(Current Science Association, 1989)
Data concerning to geological setting physical characteristics and bulk chemical composition of the nodules sampled from CIOB were stored in the Computer Data Bank of this Institute. Bulk chemical composition of nodules, ...
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 ...
Growth rate and chemical composition of a manganese nodule from the EEZ of Seychelles
(Geological Society of India, 1989)
mhe ferro-manganese nodule collected in EEZ of Seychelles yields a growth rate of 1.5 mm/10 6Y 230Th (ex)/ and 230Th (ex)/ 232Th activity ratio methods indicating very slow growth of ferro-manganese nodules. The Mn/Fe and ...
Benthic foraminifera from shelf region between Bombay - Ratnagiri: Distribution ecology and environmental significance
(Pune: Nowrosjee Wadia College, 1989)
Marine geoscientific surveys in ports and nearshore regions of the Arabian Sea off central west coast of India
(1989)
Bathymetric, side scan sonar and shallow seismic surveys were carried out in ports and adjacent nearshore regions of the Arabian Sea off the central west coast of India. It is observed that in the regions of rivers ...
