Observed tides at Mumbai High offshore region near the continental shelf break in the eastern Arabian Sea
(Current Science Association, 2009)The observed large tidal range (up to 3 m during spring tide) at the Mumbai High offshore region located near the continental shelf break, off the central west coast of India, is described based on simultaneous tidal ... -
Physico-chemical characteristics of the coastal water off Devi estuary, Orissa and evaluation of its seasonal changes using chemometric techniques
(Current Science Association, 2009)Devi estuary is one of the major tributaries of the Mahanadi riverine system in Orissa. Modernization and industrialization in its neighbourhood in the north in the recent past have greatly influenced many tributaries of ... -
Mercury enrichment in sediments of Amba estuary
(NISCAIR, India, 2009)Concentrations of Hg, total organic carbon (TOC), Al, Fe and Mn were determined in sediment of the Amba Estuary between the mouth and the head over a distance of 24 km in December and May during 1997-2002. Temporal and ... -
Potential diagenetic and detrital sources for calcareous sediments from the Carlsberg Ridge, Indian Ocean
(Current Science Association, 2009)Six sediment cores from the Carlsberg Ridge (CR) were studied for elemental concentration, magnetic susceptibility (chi), grain size and clay mineral distribution, and sedimentation rate to decipher possible detrital and ... -
Distribution of particulate carbohydrate species in the Bay of Bengal
(Indian Academy of Sciences, 2009)Suspended particulate matter (SPM) of surface seawaters was collected during December 2003 to October 2004 at 10 stations in the Bay of Bengal, and analyzed for particulate organic carbon (POC), total particulate nitrogen ... -
Comparison of the accuracy of SST estimates by artificial neural networks (ANN) and other quantitative methods using radiolarian data from the Antarctic and Pacific Oceans
(The society of Earth Scientists, 2009)The quality of quantitative estimates of sea surface water temperatures (SSTs) is evaluated for different techniques, Imbrie-Kipp transfer functions (IKTF), the modern analog technique (MAT), weighted-averaging partial ... -
Premonsoonal water characteristics and cirulation in the east central Arabian sea
(Indian Academy of Sciences, 1991)The hydrographic structure in the east central Arabian Sea during premonsoon period undergoes significant temporal change in the thermal field of upper 100 m, wherein temperature rises by about 0.5 degrees C on an average ... -
Observed low-frequency currents in the deep mid-Arabian sea
(Pergamon, 1991)Current meter records form approximately 1000 and 3000 m at three moorings with a zonal separation of about 5 degrees along the 15 degrees N latitude in the mid-Arabian Sea during May 1986 to May 1987 have used to described ... -
A subsurface cyclonic eddy in the Bay of Bengal
(Yale University, 1991)CTD data collected from the Northwestern Bay of Bengal during late July 1984 reveal the existence of a cold core subsurface eddy centred at 17 degrees 40'N and 85 degrees 19'E. The thermal structure observed across the ... -
Approximate equations at breaking for nearshore wave transformation coefficients
(NIO, Goa, 1991)Based on small amplitude wave theory approximate equations are evaluated for determining the coefficients of shoaling, refraction, bottom friction, bottom percolation and viscous dissipation at breaking. The results obtainEd. ... -
Morphological changes at Godavari delta region due to waves, currents and the associated physical processes
(Geological Society of India, 1991)Wave conditions, the most important in coastal modification, prevailing in the region of Godavari Delta for different seasons are illustrated. The analysis of GEOSAT altimeter data for the period November 1986 to October ... -
Implication of thermal discharges into the sea - A review
(Kalpana Corporation, 1991)The adverse effects of thermal discharges into coastal waters from power plants have been reviewed. The direct and indirect impacts of thermal pollution to marine biota have been discussed briefly. The tolerance limits ... -
Current measurements over the western continental shelf of India
(Pergamon, 1991)Current meter observations obtained from a site off Goa (15 degrees 08'N, 73 degrees 16'E) over the western continental shelf of India are presented. Data were collected from the site during three different months in a ... -
Wave statistics around the Indian coast based on ship observed data
(NISCAIR, New Delhi, 1991)Wave characteristics around the Indian Coast are discussed based on the ship reported wave data compiled over 19 y (1968-1986). This data have been compared with instrumentally measured waves at 2 locations (Kakinada on ... -
Wave measurement in severe ocean currents
(Institution of Engineers, India, 1991)The measurement of ocean waves has been of particular interest, as wave data and understanding of wave phenomena are essential to ocean engineering, coastal engineering and to many marine operations. The National Institute ... -
Marine meteorology and fisheries
(NIO, Goa, 1991)Weather conditions over the sea affect the fisheries both directly and indirectly. Fishing activity gets hampered even at moderate sea state conditions, and under low winds, if the swell is predominant in the operational ... -
Ocean wave nonlinearity and phase couplings
(NISCAIR, New Delhi, 1991)Bispectrum of a swell dominated sea state is computed using Fourier coefficients from an original record and from simulated Fourier coefficients using pseudorandom (uniform) phase spectrum. The differences in the bispectra ... -
Wind-driven coastal upwelling along the western boundary of the Bay of Bengal during the southwest monsoon
(Pergamon, 1991)A hydrographic survey during the southwest monsoon (July-August 1989) showed that along most of the western boundary of the Bay of Bengal, in an approximately 40 km wide band, isopycnals from depths up to about 70 m surfaced ...
