Nitrous oxide emissions from the Arabian Sea: A synthesis
(European Geophysical Society, 2001)High-resolution (1 degree x 1 degree longitude) seasonal and annual nitrous oxide (N sub(2) O) concentration fields for the Arabian Sea surface layer using a database containing more than 2400 values measured between ... -
The oceanic fixed nitrogen and nitrous oxide budgets: Moving targets as we enter the anthropocene?
(Institut de Ciencies del Mar de Barcelona, 2001)New data forced to raise previous estimates of oceanic denitrification. The revised estimate of approx. 450 Tg N yr sup(-1) (Tg = 10 sup(12) g) produces an oceanic fixed N budget with a large deficit (approx. 200 Tg N yr ... -
Environmental impact assessment: A management tool to safeguard environment and case studies
(Central Institute of Fisheries Education, Mumbai, 2001) -
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 ... -
Geochemistry of sediments
(Oxford and IBH, New Delhi, 2001)Considering the potential of elemental data in marine sediments as diagnostic tools of various geological and oceanographic processes, sediment geochemical data from the Indian Ocean region has been reviewed in this article. ... -
Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ... -
Isotopic studies of beach rock carbonates from Konkan, central west coast of India
(New Academic Publishers, Delhi, 2001)The beach rock carbonates from the 200 km long stretch from Guhagar in the north to Deogad in the south along the Konkan coast (Maharashtra, India) are studied for sup(14)C dating and sup(13)C : sup(12)C and sup(18)O : ... -
Seafloor spreading magnetic anomalies in the Enderby Basin, East Antarctic
(Elsevier, 2001)The timing of the early separation of India from the contiguous Antarctic-Australia is still an unresolved problem although it is well established that Antarctica and India formed a single Indo-Antarctic platform prior to ... -
Sediment redistribution during simulated benthic disturbance and its implications on deep seabed mining
(Pergamon, 2001)A benthic disturbance experiment was conducted in the Central Indian Basin to evaluate the possible effects of sediment redistribution on marine ecosystem during deep-sea mining. The analyses of disturbance features on the ... -
Indian Deep-sea Environment Experiment (INDEX): An appraisal
(Pergamon, 2001)Indian Deep-sea Environment Experiment (INDEX) is a multi-disciplinary study to establish baseline conditions and evaluate the possible impact of deep-seabed mining in Central Indian Basin. A disturbance was simulated to ... -
Environmental Impact Assessment (EIA) studies for deep-sea mineral exploration in the Indian Ocean
(Geological Survey of India, 2001) -
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 ... -
Geomorphology and geology of the Bay of Bengal and the Andaman Sea
(Oxford and IBH, New Delhi, 2001)Marine geological studies in the Bay of Bengal were initiated by the Andhra University in early 1950's and have subsequently become widespread during the International Indian Ocean Expedition (IIOE - 1962-65). Geomorphological ... -
Crustal structure and tectonics of the Ninetyeast Ridge from seismic and gravity studies
(American Geophysical Union, 2001)Seismic reflection and refraction, gravity, and bathymetric data across and along the central part of the Ninetyeast Ridge were analyzed to determine the crustal structure of the ridge and to understand its tectonics. The ... -
Otoliths in continental shelf and slope surficial sediments off Saurashtra, Arabian Sea, India and their significance
(New Academic Publishers, Delhi, 2001)Otoliths are a viable and underutlized paleoceanographic tool. In India a considerable amount of work has been done on otoliths of the fresh water fishes, however no significant report is available for marine otoliths. In ... -
Optimum sampling interval for evaluating ferromanganese nodule resources in the central Indian Ocean
(Springer, 2001)A study to estimate manganese nodule abundance (weight of nodules in kg/m sup(2)) was carried out in a small area of the abyssal plains covering a one-degree square block in the central Indian Basin. Abundance was assessed ... -
Structure and tectonic evolution of the northeastern Indian Ocean
(Oxford and IBH, New Delhi, 2001)Success of the International Indian Ocean Expedition Program (IIOE,1960-'65) induced an undying stimulus to all the geoscientists to probe further to unravel the various geodynamic and plate kinematic processes that are ... -
Glacial to Holocene fluctuations in hydrography and productivity along the southwestern continental margin of India
(Elsevier, 2001)Oxygen isotope and sedimentological records of a sediment core from the southwestern continental margin of India are used to reconstruct the fluctuations in sea surface hydrography and productivity during the last deglaciation. ... -
