Texture, carbonate content and component composition of Mauritius beach sands, Indian Ocean
(Tirunelveli: JCSONLINE, 1988)
Samples collected from beaches bordering the southern, southeastern, western and northwestern shores representing swell (windward) and non-swell (leeward) dominated environments of the island of Mauritius were studied in ...
Influence of seamount topography on the local facies variation in ferromanganese deposits in the Indian Ocean
(Elsevier, 1988)
The morphology and chemistry of ferromanganese nodules and encrustations from a seamount in the Central Indian Ocean Basin show local variations. Nodules from the summit of the seamount have sporadic distribution, are less ...
Microbial origin of the phosphorites of the western continental shelf of India
(Elsevier, 1988)
Phosphatised algal nodules were recovered by dredging from the western continental shelf off Goa at depths ranging from 70 to 150 m. Energy dispersive X-ray analysis indicates that the phosphorus present in the algal nodules ...
Exploration of the continental margins of India
(International Hydrographic Bureau, 1987)
In mid 1970's the National Institute of Oceanography, Goa, India prepared a plan for systematic regional, geological and geophysical surveys of the continental margins of India. This involved over 75,000 km of underway ...
Carbonate mineralogy and faunal relationship in tropical shallow water marine sediments: Cape Comorin, India
(Elsevier, 1982)
The carbonate mineralogy of Recent sediments from the western and eastern continental shelves around Cape Comorin off the southern tip of India was determined by X-ray diffraction analyses. The results show that 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 ...
Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
(Elsevier, 1987)
Todorokite is the dominant mineral phase in the nodules of the northern Central Indian Ocean Basin. These nodules are characterised by a rough surface texture, are relatively rich in Mn, Cu and Ni, and are associated with ...
Identification and origin of a subsurface ridge on the continental margin of western India
(Elsevier, 1994)
Gravity and magnetic studies in the eastern Arabian Sea reveal the presence of subsurface and exposed ridges on and beyond the continental shelf of western India. Distinct patterns of geophysical anomalies are associated ...
Carbonate preservation during the 'mystery interval' in the northern Indian Ocean
(Terra Scientific Publishing Company, 2016)
To understand carbonate dissolution and/or preservation on the sea floor since the Last Glacial Maximum (LGM), we measured shell weights of planktonic foraminifera Globigerinoides ruber from four sediment cores retrieved ...
Petasaria heterolepis (Prymnesiaceae) from the southern Indian Ocean
(Micropaleontology Press, 2015)
Sea surface and sub-surface (0-110m) water samples were collected from the Southern Indian Ocean between 39°S and 65°S (along ~48°E and 57.3°E) during the austral summer of 2010 which yielded Petasaria heterolepis Out of ...
