Organic carbon and humic acids in sediments of the Arabian Sea and factors governing their distribution
Organic carbon and humic acids in the sediments of the Arabian Sea show distinct regional variations to the south and north of 15~'N latitude. Significant variations are also observed from the shelf to the slope regions. ...
Grain size studies on the nearshore sediments of Jaigad, Ambwah and Varvada Bays, Maharashtra
(Geological Society of India, 1997)
Bivariate plots of the textural parameter data suggest overlapping environments, such as river/beach to JB, beach/dune/river to AB and dune/beach to VB sediments.
Seabottom backscatter studies in the western continental shelf of India
(Academic Press, 1999)
The study is initiated to observe the interaction effects of the sound signal with three different sediment bottoms in the shelf area between Cochin and Mangalore in the western continental shelf of India. An echo signal ...
Diagenetic remobilization of rare earth elements in a sediment core from the central Indian Basin
(NISCAIR, CSIR, 1997)
Rare earth elements (REE) distribution in a 36 cm long sediment box core from the Central Indian Basin is studied. REE concentration is generally higher in the upper oxic zone than in intermediate suboxic zone suggesting ...
Manganese in the shelf sediments off the west coast of India
(Current Science Association, 1968)
The distribution pattern of manganese in the marine sediments of the west coast of India was studied in relation to the source and environmental factors. The progressive decrease in the manganese content of the sediments ...
Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)
Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ...
Mineralogy of the carbonate sediments - western continental shelf of India
An X-ray diffraction study of forty-six sediment samples and three oolitic limestone samples from the western continental shelf of India shows that aragonite is the dominant carbonate mineral (99% maximum), followed by ...
Studies on the sediments of Vembanad Lake, Kerala State: Part I - Distribution of organic matter
Distribution patterns of FE, Mn, Ti, Ni, Co and Cu in sediments of Vembanad Lake and adjoining river systems have revealed that (1) elemental concentrations follow closely the texture of the sediments, (2) river sands ...
Verdine and glaucony facies from surficial sediments of the eastern continental margin of India
The present paper reports the first mineralogical description of green grains (verdine and glaucony) from sediments of the eastern continental margin of India. Only 24 of the 82 sediment samples studied, at depths between ...
Beach processes between Mulgund and Shiroda, west coast of India
Study on beach processes for an year shows seasonal changes without annual net erosion. The beaches are stable and regain the maximum profiles during February to April. Distribution of longshore current direction is not ...
