Distribution pattern and morphochemical relationships of manganese nodules from the Central Indian Basin
(Springer, 2001)In the Central Indian Basin manganese nodule abundance was variable in all sediment types. Mean abundance varied from 1.5 in calcareous ooze to 10.2 kg/m sup(2) in terrigenous-siliceous ooze sediments. Nodule grade and ... -
Role of sediment particles in mining of polymetallic nodules in the Central Indian Ocean
(Hindi Vigyan Sahitya Parishad. Mumbai, 2001) -
Estimation of sediment properties during benthic impact experiments
(Taylor and Francis, 2001)Sediment properties, such as water content and density, have been used to estimate the dry and wet weights, as well as the volume of sediment recovered and discharged, during benthic impact experiments conducted in the ... -
Quaternary changes in paleomonsoon: Evidences from seas

Gravity anomalies and crustal structure of the Bay of Bengal
(Elsevier, 2001)The Bengal Fan is covered afresh by systematic geological and geophysical investigations by National Institute of Oceanography (NIO), India and a detailed free-air gravity map of the fan is prepared. The map shows two ... -
Analysis of multibeam-hydrosweep echo peaks for seabed characterisation
(Springer, 2001)Echo-peak data of outer and normal incidence beams from five different Southern Ocean bottom topographic regions have been analysed. The Rice and Extremal probability density function (PDF) statistical approaches reveal ... -

Acoustic seafloor sediment classification using self-organizing feature maps
(IEEE, 2001)A self-organizing feature map (SOFM), a kind of artificial neural network (ANN) architecture, is used in this work for continental shelf seafloor sediment classification. Echo data are acquired using an echosounding system ... -
Signatures of Late Quaternary sea-level changes and Neo-tectonic activity over Visakhapatnam - Gopalpur shelf, east coast of India
(New Academic Publishers, Delhi, 2001)High-resolution shallow seismic and echo sounding profiles of the continental shelf between Visakhapatnam and Gopalpur reveal prominent morphological features like terraces, reefs and pinnacles at different water depths ... -
Western Indian Ocean - A glimpse of the tectonic scenario
(Oxford and IBH, New Delhi, 2001)The Western Indian Ocean is a veritable storehouse of diverse and complex tectonic features. Most of the knowledge about the major tectonic features of this area has emanated from the studies carried out with the geophysical ... -
Mineral resources
(Oxford and IBH, New Delhi, 2001)Marine minerals have been center of attraction to mankind since ancient times. The technological advances in the recent years show that the retrieval of underwater minerals from deep-sea can no longer be a dream. Marine ... -
The composition and the source of hydrocarbons in sediments taken from the tectonically active Andaman Backarc Basin, Indian Ocean
(Elsevier, 2001)Concentrations of total hydrocarbons in sediments of the tectonically active part of the Andaman Basin ranged from 130-720 (with an average of 349) mg/kg in the most active Spreading zone (the Rift Valley) to 43-180 (with ... -
Evidence for multiphase folding of the central Indian Ocean lithosphere
(Geological Society of America, 2001)Long-wavelength (100-300 km) folding in the central Indian Ocean associated with the diffuse plate boundary separating the Indian, Australian, and Capricorn plates is Earth's most convincing example of organized large-scale ... -

A compact self-recording pressure based sea level gauge suitable for deployments at harbour and offshore environments
(SYMPOL, 2001)A compact and lightweight self-recording pressure based sea level gauge has been designed to suit deployments from harbour and offshore environments. A novel hydraulic coupling device designed in-house was used to transfer ... -
Platform attitude data acquisition system
(SYMPOL, 2001)A system for automatic acquisition of underwater platform attitude data has been designed, developed and tested in the laboratory. This is a micro controller based system interfacing dual axis inclinometer, high-resolution ... -
Development of an integrated data acquision system for research vessels
(Anna University, Chennai;, 2001)This article describes an integrated data acquisition system (IDAS) designed and developed for multi-oceanographic research vessels. The prime motivation was to provide a flexible system, which could be used in the context ... -
New bromotriterpene polyethers from the Indian alga Chondria armata
(Pergamon, 2001)Six new bromotriterpene polyethers, armatol A-F (1-6), with a rearranged carbon skeleton, were isolated from the Indian Ocean red alga Chondria armata. The structures were characterized by spectroscopic techniques, in ... -
Methane in coastal and offshore waters of the Arabian Sea
(Elsevier, 2001)Measurements of methane (CH sub(4)) made during two surveys in the eastern and central Arabian Sea in April-May, 1996, and August-September, 1997, corresponding to late Spring Intermonsoon (SI) and Southwest Monsoon (SWM) ... -
Bioactive substances
(Oxford and IBH, New Delhi, 2001)Chemistry related to certain bioactive molecules, from Indian Ocean Region, developed into drugs or which served as models for the synthesis of more effective bioactive substances or in use in fundamental studies of ...
