Major, trace, and rare earth elements in the sediments of the Central Indian Ocean Basin: Their source and distribution
(Taylor and Francis, 2001)
The distribution maps of elements show that highest concentrations of Mn, Cu, Ni, Zn, Co, and biogenic opal in the surface sediment occurs between 10 degrees S and 16 degrees S latitude, where diagenetic ferromanganese ...
Echo-waveform classification using model and model free techniques: Experimental study results from central western continental shelf of India
(Marine Technology Society, 2005)
Seafloor classifications and characterization using acoustic backscatter data from the central western continental shelf of India is presented in this work. Single beam sea-floor echo data using two frequencies: 33 kHz and ...
Cellular-based sea level gauge
(The Hindu, 2006)
The National Institute of Oceanography has developed a coastal sea-level monitoring system that can be accessed on the Internet.
Response of the equatorial Pacific to chlorophyll pigment in a mixed layer isopycnal ocean general circulation model
(American Geophysical Union, 2001)
The influence of phytoplankton on the upper ocean dynamics and thermodynamics in the equatorial Pacific is investigated using an isopycnal ocean general circulation model (OPYC) coupled with a mixed layer model and remotely ...
Manganese oxidation by bacterial isolates from the Indian Ridge System
(Springer, 2005)
The abundance and activity of culturable manganese-oxidizing bacteria were assessed from near-bottom water samples of the tectonically active Carlsberg Ridge. Retrievable counts as colony forming units (CFU) on dilute ...
Environmental impact assessment - A management tool for conservation of large marine ecosystems
(Fishery Survey of India, 2004)
Coastal development includes a variety of activities which will have significant impact on marine ecosystem especially in the shallow nearshore areas. The stress relevant to coastal zone emerge from hinterland activities, ...
Variability of surface circulation of the Indian Ocean
(Andhra University, 2007)
Drift pumice in the central Indian Ocean Basin: Geochemical evidence
(Elsevier, 2008)
Abundant white to light grey-coloured pumice without ferromanganese oxide coating occurs within the Quaternary sediments of the Central Indian Ocean Basin (CIOB). Two distinct groups of pumice are identified from their ...
Air-sea exchanges of materials in the Indian Ocean: Concerns and strategies
(AP Akademi of Sciences, India, 2004)
Exchanges of materials at the air-sea interface are linked to earth's heat budget and the natural balance is being increasingly affected by human activities. Three major issues of national concern with respect to changes ...
Buried nodules from the central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)
The occurrence of buried nodules is rare compared to surface nodule abundance in the deep sea. Surface nodules are collected with freefall grab, vanveen /peterson grabs, dredges and sediment cores whereas buried nodules ...
