A note on the Pavonina flabelliformis D'Orbigny (benthic foraminifera) from the Arabian Sea
(Association of Korean Geoscience Societies, 1994)
The detailed study of the inner shelf surface sediments off Karwar (India) revealed the occurrence of a benthic foraminiferal species Pavonina flabelliformis. This is the first report of this species in the Arabian Sea. ...
Distribution of manganese nodules, rocks and sediments in the Central Indian Ocean Basin: Factors influencing performance of mining system
(Publ. and Inf. Dir., New Delhi, India, 1994)
Manganese nodule abundances in the Central Indian Ocean Basin (CIOB) as noted from seabed photographs (nil to 18.4 kg/m sup(2)) and grabs (nil to 21.5 kg/m sup(2)) are variable. The relative abundance varies from zero to ...
Use of sparker signal to classify seafloor sediment
(Publ. and Inf. Dir., New Delhi, India, 1994)
During the cruise 190 of R.V. Gaveshani, the sparker signal was recorded in the analog form on audio cassettes. This signal has been digitized and a statistical computation, viz. the normalized cross-correlation function ...
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 ...
Study of sub-surface sediments from northern Indian Ocean: Oceanic responses to climatic changes
(Palaeontol. Soc. India, 1994)
The mean diameter and variation in isotopic composition (delta sup(18)) in thest of Orbulina universa d'Orbigny have been measured in a sediment core collected from 3869 m water depth near the Carlsberg Ridge, northern ...
Antibacterial and antifungal activity of streptomycetes isolated from Portonova coastal environment. Papers presented in the symposium held at Cochin, India, 16-17 September 1993
(Society of Fisheries Technologists (India), Cochin, 1994)
The antibacterial and antifungal activities of 518 streptomycetes strains were tested against Bacillus circulans, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Saccharomyces cerevisiae and Fusarium ...
