Ablated tektite from the central Indian Ocean
(Meteoritical Society, Fayetteville, USA, 1996)
A well-preserved ablated (button-shaped) tektite recovered from the surface sediments of the central Indian Ocean lacks flow ridges and has apparently undergone ablation of 6.9 to 7.9 mm. The lack of flow ridges and amount ...
State of oil pollution in the northern Arabian Sea after the 1991 Gulf oil spill
(Pergamon, 1993)
Following the enormous oil spills resulting from the 1990-91 military conflict in the Gulf, fears were expressed concerning dissipation of oil from the Gulf into the Arabian Sea and Indian Ocean. To investigate contamination ...
A geophysical survey of the De Gerlache Seamounts: Preliminary results
(Springer, 1998)
The De Gerlache Seamounts actually consist of two medium-sized guyots, with summits at depths of 350-600 m. Acoustic profiler data show no significant sediment on these guyots. Alkaline basalts dredged from the summit of ...
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 ...
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 ...
Verdine and glaucony facies from surficial sediments of the eastern continental margin of India
(Elsevier, 1995)
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 ...
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
(Springer, 1997)
Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ...
New evidence for enhanced preservation of organic carbon in contact with oxygen minimum zone on the western continental slope of India
(Elsevier, 1993)
In order to evaluate the reason for organic enrichment on the western continental slope of India, we provide Rock-Eval pyrolysis data of 25 surficial sediment samples from this area. Results show that the organic matter ...
