Paleogene Reworked Foraminifera in Recent Sediments off Daman, Western India
(1980)
The first record of reworked foraminiferal species in the Recent sediments off the coast of Daman is reported. Among others, @iQuadrimorphina advena, Uvigerina minuta, Gyroidinoides soldani, Bulimina aguafrescanensis@@ and ...
Distribution of Strontium in Sediments of the Minicoy Atoll, Lakshadweep
(CSIR-NISCAIR, 1980)
Sr content in 67 sediment samples collected from the Minicoy reef and lagoon varies from 3960 to 7000 ppm (av. 5630 ppm). The concentration increases from the reef (c 4,000 ppm) in the north and west to the centre of the ...
Magnetic Surveys of the Continental Shelf off Visakhapatnam
(Indian Association for Limnology and Oceanography, 1980)
Continuous magnetic surveys over the continental shelf off Visakhapatnam reveal total magnetic field anomalies of high amplitude and short period over the inner shelf and of comparatively low amplitude with long period ...
General Expression for Spectrum of Magnetic Anomaly due to long Tabular body and its Characteristics
(CSIR-NISCAIR, 1980)
A general expression for spectrum of magnetic anomalies-vertical, horizontal and total intensity - due to a long tabular body is derived which is used to estimate the body parameters. The analysis is extended to a marine ...
Relationship between Benthic Foraminifera and Sediment in the Estuarine Complex of Goa
(Indian Association for Limnology and Oceanography, 1980)
Two indices of community association were used to elucidate the relationship between changes in species composition of benthic foraminifera and changes in the grain size composition of the sediment in estuarine complex of ...
Topographic Features over the Continental Shelf off Visakhapatnam
(Indian Association for Limnology and Oceanography, 1980)
Continuous echosounding surveys have been carried out along sixteen profiles covering the entire continental shelf between Bheemunipatnam and Kutukonda. Over the inner shelf and mid-shelf the bottom topography is smooth ...
Sandwaves of the Gulf of Khambhat
(CSIR-NISCAIR, 1980)
In the Gulf of Khambhat (Gujarat, India) the best formed sandwaves are seen in the west close to the Eastern Sand Bank. With increasing clay content and clay cover of the sea bed, the sandwaves become poorly formed. In the ...
Excentricity and Twinning in Virgulinella Pertusa (Reuss)
(Madrid : Empresa Nacional "Adaro" de Investigaciones Mineras S.A., Centro de Investigacion Juan Gavala, 1980)
In @iVirgulinella pertusa@@, one instance of bizarre growth of the last three chambers, another case of sudden spurt of development in the last three chambers and one case of abnormality in the chamber size and inflation ...
Distribution of Al, Mn, Ni, Co & Cu in the Non-Lithogenous fractions of Sediments of the Northern Half of the Western Continental Shelf of India
(CSIR-NISCAIR, 1980)
Higher amounts of elements are associated with the nonlithogenous fractions of the fine grained terrigenous sediments of the innershelf region with low carbonate content than with the corresponding fractions of the coarse ...
Acoustic Masking due to Gases in Shallow Seismic profiling on the shelf off Bombay
(CSIR-NISCAIR, 1980)
Shallow seismic profiling on the inner shelf off Bombay indicates 25-35 m thick acoustically transparent clays covering the seabed. At depth of 22 to 30 m and 50 m the profiles and echograms are marked by turbidity resembling ...
