Benthic fauna of southwest and southeast coasts of India
(Asian Fisheries Society, Indian Branch, Mangalore (India), 1999)
Benthos, sediments characteristics and organic matter content were studied along southwest and southeast coasts of India. Number of groups/species varied with the stations and also with the depths. Population density was ...
Speciation of iron and manganese in the sediments of Mandovi Estuary
(CAS in Marine Biology, Parangipettai, 1991)
Several attempts have been made to study the distribution of iron and manganese in Mandovi Estuary, Goa, India. But this is the first report of its kind on the speciation of these metals in sediments from Indian waters. ...
Geochemical trends in the sediments and manganese nodules from a part of the Central Indian Basin
(Geological Society of India, 1994)
Geochemical analyses of eighteen surface sediments samples collected from an area between 1 degree-15 degrees S latitudes and 73 degrees-87 degrees E longitudes exhibit significant variation in their chemical ...
Beach processes between Mulgund and Shiroda, west coast of India
(CSIR-NISCAIR, 1994)
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 ...
On the occurrence of ferromanganese micronodules from the sediments of the Bengal Fan: A high terrigenous sediment input region
(Elsevier, 1994)
Studies of 13 samples (10 surface sediments and 3 cores) from across the middle fan region of the Bay of Bengal reveal the presence of micronodules (area 0.22 million km@u2@@) over the entire bay. These micronodules have ...
On the surficial sediments of the fresh water Naini Lake, Kumaun Himalaya, India
(Indian Academy of Sciences, Bangalore, 1994)
The 1.4 km long and 0.45-0.25 km wide crescent shaped Naini Lake in the Nainital District of Kumaun Himalaya, India is divided by an east-west running transverse Central Ridge into two sub-basins. These northwest and ...
Radiolarian abundance and geochemistry of the surface-sediments from the Central Indian Basin: Inferences to Antarctic bottom water current
(Current Science Association, 1994)
The distribution trend of numbers of radiolarian shells/gram dry sediment, biogenic silica, organic carbon, and the carbon/nitrogen ratios in the surface sediments of the Central Indian Basin is similar. Ratios of two ...
Granulometric analyses of pelites using a sedigraph: Examples from a Volcano-sedimentary environment
(Geological Society of India, 1993)
This article presents granulometric data of pelites (less than 40 microns) of mixed composition from a volcano-sedimentary environment. The sedigraph serves as an useful tool in the analyses of silt-clay fraction of marine ...
Structural characteristics of marine sedimentary humic acids by CP/MAS sup(13)C NMR spectroscopy
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1998)
Humic acids from sediments of different depositional environments have been studied by solid-state sup(13)C NMR and the results compared with the traditional wet chemical analysis. Results obtained are well in agreement ...
Lithological and mineralogical changes observed in a core from the western Bay of Bengal
(Allied, New Delhi (India), 1997)
Lithological and mineralogical studies were carried out on sediments from a 650 cm long core from the north western Bay of Bengal at a depth of 2700 m. These studies demarcate a boundary at 380 cm designated as unit 1 from ...
