Seasonal variability in oxygen and nutrients in the central and eastern Arabian Sea
(Indian Academy of Sciences, 1996)Extensive observations made in the central and eastern Arabian Sea under JGOFS (India) programme suggest strong seasonal variations in concentrations of oxygen and nutrients in the water column. In the intermediate waters ... -
Characterization of purple and green photosynthetic bacteria isolated from the lagoon of Agatti Atoll (Lakshadweep Sea)
(Indian Academy of Sciences, 1986)The occurrence and characterisation of photosynthetic sulphur bacteria in the tropical waters is reported. These were found with decaying beds of seagrass at Agatti Island, Lakshadweep, India. These were cultured and ... -
Climate of the northern Indian Ocean and associated productivity
(International Society for Tropical Ecology, 1985)The climatic factors likely to influence the phytoplankton production in the northern Indian Ocean are examined. The major cause for the high productivity of the Arabian Sea is the nutrient enrichment of the euphotic zone ... -
Monsoon wind and maritime trade: A case study of historical evidence from Orissa, India
(Indian Academy of Sciences, 2006)Monsoon plays a predominant role in the daily life of the people of South Asia. The use of monsoon wind in the Indian Ocean for maritime trade was a boon to the sailing ships to reach overseas countries. It is believed ... -
Sea level during storm surges as seen in tide-gauge records along the east coast of India
(Indian Academy of Sciences, 1999)Analysis of hourly sea level recorded by tide gauges of the Survey of India (SOI) at Paradip, Vishakhapatnam, and Chennai provides a record of non-tidal sea level during three periods, 6-10 August 1979, 6-10 August 1981, ... -
Seasonal cycle of sea level and currents along the coast of India
(Indian Academy of Sciences, 2000)A framework involving long baroclinic waves, which treats the north Indian Ocean as a single dynamical entity, has been remarkably successful in simulating the low-frequency, large-scale circulation in the ocean. It is, ... -
Marine Archaeology in India
(Indian Society for Prehistoric and Quaternary Studies, 2004)Marine archaeology, also known as maritime, nautical or underwater archaeology deals with the ‘scientific study of the material remains of man and his past activities on the sea’. Marine archaeology has made tremendous ... -
Use of timber in shipbuilding industry: Identification and analysis of timber from shipwrecks off Goa coast, India
(Indian Academy of Scinces, 2005)The use of timber in the boatbuilding or shipbuilding industry is as old as the construction of boats and ships. Various kinds of timber are used in different regions of India in the construction of vessels. The Yuktikalpataru ... -
Maritime heritage in and around Chilika lake, Orissa: Geological evidences for its decline
(Indian Academy of Sciences, 2005)Chilika (also spelt Chilka) lake is the largest brackish water body in India. Archaeological explorations and excavations around the Chilika lake region have brought to light the habitational remains of the Neolithic-Chalcolithic ... -
Shipwreck archaeology of Goa: Evidence of maritime contacts with other countries
(Indian Academy of Sciences, 2004)Shipwrecks contain clues to our maritime heritage. The shipwreck history of Goa is as old as the maritime history, which dates back to 2nd century BC. However, information on shipwrecks prior to the Portuguese period in ... -
Biogeochemistry of the Bay of Bengal: Physical, chemical and primary productivity characteristics of the central and western Bay of Bengal during summer monsoon 2001
(Elsevier, 2003)Reliable data on biological characteristics from the Bay of Bengal are elusive. In this paper, we present results on physics, chemistry and biology simultaneously measured during the summer monsoon, 2001 from open ocean ... -
The monsoon currents in the north Indian Ocean
(Pergamon (Elsevier), 2002)The monsoon currents are the seasonally reversing, open-ocean currents that flow between the Arabian Sea and the Bay of Bengal, the two wings of the north Indian Ocean. The Summer Monsoon Current (SMC) flows eastward ... -
Low-frequency variability of sea level along the coast of India
(1998)Coastal sea level is one of the better documented oceanic variables, there being several tide-gauge records of hourly sea level that stretch back to the last century. This, together with the fact that geostrophic, low-frequency ... -
On the sea surface temperature high in the Lakshadweep Sea before the onset of the southwest monsoon
(American Geophysical Union, 1999)The north Indian Ocean becomes the warmest area of the world oceans prior to the onset of southwest monsoon in June. During this period a zonal band of high sea surface temperature (SST), the ``thermal equator'' (TE), moves ... -
Remote forcing annihilates barrier layer in southeastern Arabian Sea
(American Geophysical Union, 2004)Time-series measurements of temperature and salinity profiles were made every two hours at 74 deg 30'E, 9 deg 13'N in the southeastern Arabian Sea (SEAS) during 22 March to 7 April and 23 May to 7 June 2003 as part of ... -
Observational evidence for westward propagation of temperature inversions in the southeastern Arabian Sea
(American Geophysical Union, 2004)A warm pool forms in the southeastern Arabian Sea (SEAS) prior to the onset of the summer monsoon over India in early June; the core of this warm pool is in the Lakshadweep Sea (LS). XBT and surface salinity data collected ... -
Are interdecadal sea level changes along the Indian coast influenced by variability of monsoon rainfall?
(American Geophysical Union, 1999)The Mumbai (Bombay) tide gauge data, the only century-long record in the Indian Ocean, show that interdecadal changes in sea level mimic those in rainfall over the Indian subcontinent. We propose that the link between ... -
Why is mean sea level along the Indian coast higher in the Bay of Bengal than in the Arabian Sea?
(Americal Geophysical Union, 2001)Levelling observations conducted during the Great Trigonometrical Survey of India (1858-1909) and subsequent observations showed that mean sea level along the coast of India is higher in the Bay of Bengal than in the Arabian ... -
Hydrography and water masses in the southeastern Arabian Sea during March-June 2003
(Indian Academy of Sciences, 2005)This paper describes the hydrographic observations in the southeastern Arabian Sea (SEAS) during two cruises carried out in March–June 2003 as part of the Arabian Sea Monsoon Experiment. The surface hydrography during ... -
A quantitative framework for estimating water resources in India
(Indian Academy of Sciences, 2004)While issues related to water attract considerable attention in all spheres of life in India, very little quantitative information is available on the water budget of the country. There are primarily two reasons for this ...
