Distribution of total phosphorus in the Bay of Bengal
(National Institute of Sciences of India, 1968)The total phosphorus content in the sediment samples collected from different stations on the continental shelf along five sections normal to the coast near Bombay, Karwar, Mangalore, Cochin and Alleppey has been determined ... -
Distribution of total phosphorus in the shelf sediments off the west coast of India
(National Academy of Sciences, India, 1968)The total phosphorus content in the sediment samples collected from different stations on the continental shelf along five sections normal to the coast near Bombay, Karwar, Mangalore, Cochin and Alleppey has been determined ... -
Driving forces of Indian summer monsoon on Milankovitch and sub-Milankovitch time scales: A review
(Geological Society of India, 1998)A scientific consensus exists that tectonic evolution of Himalaya is the main cause of monsoon initiation and evolution in southeast Asia. Several forcing factors such as tectonic, solar insolation, latent heat transport, ... -
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. ... -
Hydrographic characterization of southeast Arabian Sea during the wane of southwest monsoon and spring intermonsoon
(Springer, 2008)Seasonal variation of the hydrography along the southeast Arabian Sea is described using data collected onboard FORV Sagar Sampada in September-October 2003 (later phase of Southwest monsoon, SWM) and March-April 2004 ... -
Hydrography of the Wadge bank - premonsoon and monsoon seasons
(Indian Association for Limnology and Oceanography, 1989)The hydrography of the Wadge Bank during premonsoon and monsoon seasons is presented. The thermocline slopes downward towards the central region. Upwelling is prominent in the entire region during monsoon and is observed ... -
Increased particle flux to the deep ocean related to monsoons
(Nature Publishing Group, 1989)Monsoons cause seasonal reversals in the surface circulation of the northern Indian Ocean. In the Arabian Sea this results in the upwelling of nutrient-rich water along the coasts, making it one of the highly productive ... -
Influence of upwelling on distribution of chaetognath (zooplankton) in the oxygen deficient zone of the eastern Arabian Sea.
(Elsevier, 2014)he study addresses the coupled spatial scales in the physico-chemical variables and chaetognaths in the upwelling system of the eastern Arabian Sea during the 2005 summer monsoon. We studied the taxon between 0 and 1000 m ... -
Inorganic combined nitrogen budget of the Arabian Sea: Some geochemical and climatic implications
(Waseda University, Tokyo, 1992)Estimates of the local sources and sinks of inorganic combined nitrogen in the Arabian Sea suggest a net loss of sup(-)3 x 10 sup(13) gN y sup(-1). This seems to be made up largely by the upward flux facilitatEd. by a high ... -
Interannual variability of Kelvin wave propagation in the wave guides of the equatorial Indian Ocean, the coastal Bay of Bengal and the southeastern Arabian Sea during 1993-2006
(Elsevier, 2010)The observed variability of the Kelvin waves and their propagation in the equatorial wave guide of the Indian Ocean and in the coastal wave guides of the Bay of Bengal (BoB) and the southeastern Arabian Sea (AS) on seasonal ... -
Interrelationships and distribution of hydrochemical parameters in coastal waters off Visakhapatnam, east coast of India
(Indian Association for Limnology and Oceanography, 1988)The distribution of hydrochemical parameters in the coastal waters off Visakhapatnam during the July 1979-June 1980 showed distinct changes with time The observed supersaturation and saturation of oxygen in surface waters ... -
Isotopic evidences of past upwelling intensity in the Arabian Sea
(Elsevier, 2004)Oxygen and carbon isotopic analyses have been performed on the tests of Globigerina bulloides, Globigerinoides sacculifer, Neogloboquadrina dutertrei and Pulleniatina obliquiloculata to study the delta super(18)O and delta ... -

Living coccolithophores during the northeast monsoon from the Equatorial Indian Ocean: Implications on hydrography
(Elsevier, 2005)Water samples collected at five stations along 931E section (1 degrees N-4 degrees S) during the northeast monsoon (12-15 February 2000) at five depths (surface, 50, 100, 150 and 200 m) in the eastern equatorial Indian ... -
Living coccolithophorids from the Arabian Sea
(Department of Earth Sciences, University of Milan, 1995)Coccolithophorids collected from the euphotic zone in the Arabian Sea during the tail end of summer monsoon (Sept. 20 to Oct. 06, 1992) were studied. Nineteen species were recorded, most abundant among them were, Emiliania ... -
Living planktonic foraminifera during the late summer monsoon period in the Arabian Sea
(Elsevier, 1994)During the late summer monsoon living planktonic foraminifera were collected in the southeastern Arabian Sea between 3~'N and 15~'N by using six vertical plankton tows. Sixteen species of planktonic foraminifera were ... -
Living planktonic foraminifera of the Wadge bank, Northern Indian Ocean
(CSIR-NISCAIR, 1988)Twenty three species of living planktonic Foraminifera belonging to 11 genera have been studied from the Wadge Bank area off southern tip of the Indian peninsula. The fauna is characterized by species such as Globigerinoides ... -
Locating Noctiluca miliaris in the Arabian Sea: An optical proxy approach
(Association for the Sciences of Limnology and Oceanography, 2014)Coincident with shifting monsoon weather patterns over India, the phytoplankter Noctiluca miliaris has recently been observed to be dominating phytoplankton blooms in the northeastern Arabian Sea during the winter monsoons. ... -
Mechanism of the biological response to winter cooling in the northeastern Arabian Sea
(Macmillan, 1996)The Arabian Sea is one of the most biologically productive ocean regions, mainly due to the upwelling of nutrients during the summer (southwest) monsoon. But the northern Arabian Sea continues to sustain fairly high ... -
