Objective mapping of observed sub-surface mesoscale cold core eddy in the Bay of Bengal by stochastic inverse technique with tomographically simulated travel times
(NISCAIR (CSIR), 2011)Present study consists the acoustic characteristics of a sub-surface cold core eddy observed (below the mixed layer between depths of 50 and 300m, with a diameter of about 200 km having temperature drop of 5 Degree Celsius ... -
Objective mapping of temperature field by stochastic inverse method using acoustic tomography experimental data of eastern Arabian Sea
(School of Naval Oceanology and Meteorology, 2007)An acoustic transmission experiment was conducted in the eastern Arabian Sea along 12.5 degrees N latitude for a duration of ten days (2-12 May, 1993), with two transceiver systems deployed on deep sea moorings, separated ... -
Oblique strike-slip motion off the Southeastern Continental Margin of India: Implication for the separation of Sri Lanka from India
(Pergamon, 2018)The ocean floor in the Bay of Bengal has evolved after the breakup of India from Antarctica since the Early Cretaceous. Recent geophysical investigations including updated satellite derived gravity map postulated two phases ... -
OBS ervations on the vegetative propagation of the marine alga, Gelidiella acerosa (Forssk) Feldmann and Hamel
(Seaweed Research and Utilization Association, 1996)Gelidiella acerosa is a very good source for quality agar production in India. There has been reports that the natural resource of the species is very sparse in distribution and very little in quantity compared to its ... -
Observability analysis of 2D single-beacon navigation in the presence of constant currents for two classes of maneuvers
(International Federation of Automatic Control, 2013)We analyze the observability properties of an underwater vehicle (moving in 2D) performing single beacon navigation for two specic classes of maneuvers, whereby the vehicle measures its distance to a xed transponder located ... -
Observation of dominance of swells over wind seas in the coastal waters of the Gulf of Mannar, India
(Copernicus Publications for EGU, 2017)Wind seas typically dominate over swell seas in coastal gulfs. Waves measured at a location having a water depth of 12?m in the near-shore waters of the Gulf of Mannar during a 1-year period (1 May 2015 to 30 April 2016) ... -
Observation on foreshore morphodynamics of microtidal sandy beaches
(Current Science Association, 2014)Foreshore morphology and morphodynamics were examined to identify stability of two microtidal sandy beaches, Kundapura and Padukare, along the Karnataka shoreline on the west coast of India during three annual cycles from ... -
Observation on oceanographic parameters of nearshore waters off Yanam, during the cyclonic storm
(Current Science Association, 2008)The current and temperature at different levels were measured at 75 m water depth off Yanam, (Andhra Pradesh, India) which is 12 km away from the coast for a period of 40 days during August-October 2005. The tides and winds ... -

Observation-Based Estimates of Surface Cooling Inhibition by Heavy Rainfall under Tropical Cyclones
(American Meteorological Society, 2013)Tropical cyclones drive intense ocean vertical mixing that explains most of the surface cooling observed in their wake (the "cold wake"). The influence of cyclonic rainfall on the cold wake at a global scale over the 2002-09 ... -
Observational evidence for remote forcing of the west India coastal current
(American Geophysical Union, 2008)Circulation in the north Indian Ocean is influenced by both local and remote wind forcing. So far, however, determining the contribution of these two forcing mechanisms at a location has been possible only in numerical ... -
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 ... -
Observational evidence from direct current measurements for propagation of remotely forced waves on the shelf off the west coast of India
(American Geophysical Union, 2012)We use data from six Acoustic Doppler Current Profiler (ADCP) moorings deployed during March–September 2008 on the continental shelf and slope off Bhatkal, Goa, and Jaigarh on the central west coast of India to present ... -
Observational evidence of lower-frequency Yanai waves in the central equatorial Indian Ocean
(American Geophysical Union, 2011)Analysis of long time series of current meter data from a mooring at 77 degrees E and the equator during 2003–2007, along with mean sea level anomaly data, throws light on the occurrence of the lower-frequency (24 to 40 ... -
Observational evidence of mixed rossby gravity waves at the central equatorial Indian Ocean

Observational evidence of stratification control of upwelling and pelagic fishery in the eastern Arabian Sea
(Springer-Nature, 2021)Upwelling is a physical phenomenon that occurs globally along the eastern boundary of the ocean and supports pelagic fishery which is an important source of protein for the coastal population. Though upwelling and associated ... -
