Arabian Sea oceanography and fisheries of the west coast of India
(Indian Academy of Sciences, 2001)The physical and chemical forcing, which drives the Arabian Sea production is now fairly understood. The main attributes which contribute to the productivity are (1) the boundary and open ocean processes, which manifest ... -
Littoral drift sources and sinks along the Indian coast
(Indian Academy of Sciences, 2001)Numerous theoretical and field studies have been carried out to quantify the volume and direction of littoral sediment transport along the Indian coast. Nevertheless, very little effort has been made to identify the sources ... -
New stable isotope records of sediment cores from the SE Arabian Sea - Inferences on the variations in monsoon regime during the late Quaternery
(Indian Academy of Sciences, 2001)We reconstruct here the changes in regional hydrography related to the fluctuations in Indian monsoons during the late Quaternary based on the stable isotope composition of the foraminifers and organic matter in three ... -

An occurrence of approx. 74 ka Youngest Toba tephra from the western continental margin of India
(Indian Academy of Sciences, 2001)A dispersed volcanic ash layer was recovered at ~6 300 cm depth in a 5.52 m long sediment core collected at a latitude 9~'21'E from a water depth of 2300 m on the Western Continental Margin of India (WCMI). Glass shards ... -
A deep-sea bacterium with unique nitrifying property
(Indian Academy of Sciences, 2001)Sediment cores collected from the Central Indian Basin (10°1¢–10°2¢S, 75°59¢–76°2¢E) harboured a high population of nitrifying bacteria which ranged from 103 to 107 cfu per gram dry weight. This high density could contribute ... -
Sea truth validation of sea WiFS ocean colour sensor in the coastal waters of the eastern Arabian Sea
(Indian Academy of Sciences, 2001)In this paper we report bio-optical measurements made during an ocean colour validation cruise SK 149C in November 1999 of the research vessel Sagar Kanya in the coastal waters of the Eastern Arabian Sea. The chlorophyll ... -
Foraminifera from the Chilka Lake on the east coast of India
(Marine Biological Association of India, 2000)A total of sixtynine foraminiferal species belonging to 27 genera and 19 families have been identified from the sediment samples of the Chilka lake collected during three faunal surveys representing different seasons. ... -
Does temperature affect dimorphic reproduction in benthic foraminifera? A culture experiment on Rosalina leei
(Indian Academy of Sciences, 2000)The possible effects of environmental factors on the dimorphic mode of reproduction in benthic foraminifera have been reported in the literature. Published observations based on field samples have indicated an inverse ... -

Science popularization and the Indian constitution - Correspondence
(Indian Academy of Sciences, 2000)Article 51A (h) of the Indian Constitution reads as follows, (citizens have a duty) to develop the scientific temper, humanism and the spirit of inquiry and reform. This item under basic duties is of great importance to ... -
The Himalayas revisited
(Indian Academy of Sciences, 2000)The Himalayas are a complex, uplifted and deformed mountain range, brought about by tectonic activities, culminating in a series of plate collisions, most of which are still currently active. The Indo-Eurasian Plates’ ... -
Complete regeneration of ablated eyestalk in penaeid prawn, Penaeus monodon
(Indian Academy of Sciences, 2000)Ablation of one eyestalk is generally practised in all commercial prawn hatcheries to induce gonad maturation and spawning. An observation was made that the ablated eyestalk of spent females of the tiger prawn Penaeus ... -
Primary productivity of marine macrophytes in the coral reef lagoon of the Kadmat Island, Lakshadweep
(Indian Academy of Sciences, 2000)n situ primary productivity measurements were carried out with different macrophyte species (belonging to four groups) dominating the benthic communities in the coral reef lagoon of the Kadmat Island of the Lakshadweep ... -
How safe are Indian laboratories?
(Indian Academy of Sciences, 2000)ow safe are the laboratories provided by the schools, colleges, Universities and research organizations (government and private) in India? One should not be surprised if the laboratories are located in dilapidated buildings, ... -
A documentation on burrows in hard substrates of ferromanganese crusts and associated soft sediments from the Central Indian Ocean
(Indian Academy of Sciences, 2000)Substrates of ferromanganese encrustations collected from the hummocky topography of the Central Indian Basin (CIB) (lat. 12~'25'-12~'45'S, water depth between 5150 and 5300 m) are largely composed of indurated claystone ... -
An indirect method for forecasting the annual food production of India
(Indian Academy of Sciences, 2000)The green revolution which increased the annual food production of India drastically was made possible by the application of science and technology to agriculture. The total technological inputs to the farming sector has ... -
Reflections on the Indian science congress
(Indian Academy of Sciences, 2000)The 87th Session of the Indian Science Congress (ISC) was held in the sprawling grounds of University of Pune (PU) between 3rd and 7th January 2000. Here I summarize what transpired at the earth system sciences (ESS) ... -
Ocean biogeochemistry and atmospheric composition: Significance of the Arabian Sea
(Indian Academy of Sciences, 2000)The Arabian Sea is an important site of biogeochemical ocean-atmosphere transfers, which play a crucial role in regulating the atmospheric chemical composition and the earth's climate. Widespread denitrification resulting ... -
