Slumping on the western continental margin of India
(Asociacion Argentina de Geofisicos y Geodestas, 2001)
A short gravity core from the Western Continental Margin of India has been examined to understand the nature and characteristics of slumping in the area. The present study and also the earlier studies revealed that the ...
Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
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 ...
Sediment movement on the continental shelf off Bombay, India
Daily beach profiles and littoral environmental observations off Baga, Calangute and Miramar beaches during November-December 1999
(Goa: NIO, 2002)
This report presents the results of the field observations and theoretical studies on the coastal processes at Baga, Calangute and Miramar beaches along the North Goa coast, India. The field observations undertaken for a ...
Morphological variations in the polymetallic nodules from selected stations in the Central Indian Ocean
Polymetallic nodules from the Central Indian Ocean largely range in size from 2 to 6 cm. The smaller nodules (4 cm) are subspheroidal to spheroidal in shape and with the increase in size, nodules become more discoidal and ...
Sediment characteristics at intertidal regions across Yarada beach, East coast of India
Sediment samples were collected once a month at five different inter-tidal zones across Yarada beach during May-2009 to May-2010 These sediments are characterized by bimodal and unimodal behaviour and most of them are ...
A note on an occurrence of pseudo-pumice along the beaches of Goa and Karnataka
Clasts showing typical physical features of pumice were found scattered along the beaches of Goa and Karnataka Their chemical composition suggests a large variation in SiO<sub>2</sub> content (69% to 93%), with an unusual ...
Petrography of basalts from the Carlsberg ridge
Petrographic characteristics of basalts collected from a segment of the Carlsberg Ridge (lat. 3 degrees 35'N to 3 degrees 41'N; long. 64 degrees 05'E to 64 degrees 09'E) show typical pillow lava zonations with variable ...
Mesozoic anomalies in the Bay of Bengal
The analysis of 8200 line km of total magnetic intensity data in the Bay of Bengal, northeastern Indian Ocean, revealed the presence of approximately N30~'E-trending seafloor spreading type magnetic anomalies. These anomalies ...

(Scientific Publishers, 2001)
The probable movement and mixing of contaminants within and through the Kundalika river estuary along the west coast of India are studied Neutrally buoyant biplane drogues, floats and dye were tracked at different stages ...
