A non-diatom plankton bloom controlled by copepod grazing and amphipod predation: Preliminary results from the LOHAFEX iron-fertilisation experiment
(GLOBEC, 2009)The most memorable LOHAFEX cruise came to an end on 17 March 2009 when RV Polarstern docked in the harbour of Punta Arenas (southern Chile) after successfully carrying out the longest iron fertilisation experiment so far ... -
Acoustic propagations in the presence of a subsurface cold core eddy in the Bay of Bengal - A case study
(PORSEC-94, Melbourne, Australia, 1994)Acoustic characteristics of a cold core eddy, observed in the Bay of Bengal during southwest monsoon period is studied using CTD data along the western boundary. The presence of eddy brings about a reduction in the ambient ... -
Biogeochemical significance of eddies of the eastern Arabian Sea
(Levente Hufnagel (ALÖKI Kft.), 2013)Within the Arabian Sea, the western part is considered to be highly productive when compared to the northern, central and eastern parts of the basin. Despite the contrasting chlorophyll and primary productivity patterns, ... -
Chemical absorption of acoustic energy due to an eddy in the western Bay of Bengal
(Ultrasonics Society of India, 1994)Acoustic energy losses due to chemical absorption, within the western Bay of Bengal, in the presence of a subsurface meso-scale cold core eddy has been analysed. These estimates, for two different frequencies - 400 Hz and ... -
Circulation and Water Characteristics on Isanosteric surfaces in the Northern Arabian Sea during February-April
(CSIR-NISCAIR, 1980)Distribution of water characteristics and circulation were studied on 260, 160, 140, 120 and 80 cl/t surfaces using isanosteric analysis and geostrophic computation The circulation pattern consisted of several eddies and ... -
Current structure and kinetic energy of the abyssal waters in the Central Indian Ocean Basin
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Analysis of abyssal currents measured at 7 levels viz., 4, 8, 15, 30, 50, 100 and 500 mab during October 1996-April 1997 at 10 degrees 01'S, 76 degrees E in the Benthic Disturbance Experiment Site (BDES) in the Central ... -
Detection of Bay of Bengal eddies from TOPEX and in situ observations
(Sears Foundation, 2000)Oceanic eddies have warm or cold temperatures and high or low sea surface height (SSH) at the center depending upon the direction of rotation. However, since the Bay of Bengal waters are highly stratified, sea surface ... -
Detection of Bay of Bengal eddies from TOPEX and insitu observations
(Naval Physical and Oceanographic Laboratory, Thrikkakara, Kochi, India, 1998)Oceanic eddies are characterised by gradients in the sea surface height (SSH) and temperature both at the surface and the subsurface. However, since the Bay of Bengal waters are more stratified, the gradients in SST may ... -
Determination of dynamic heights in the Bay of Bengal from XBT profiles and climatological salinities
(Sears Foundation for Marine Research, 2005)Dynamic height (DH) computations are necessary for the estimation of geostrophic currents, heat transport studies, identification of eddies and to validate the altimeter sea surface height (SSH) observations. To compute ... -
Dinoflagellate community structure from the stratified environment of the Bay of Bengal, with special emphasis on harmful algal bloom species
(Springer, 2011)Harmful algal blooms (HABs) have been documented along the coasts of India and the ill effects felt by society at large. Most of these reports are from the Arabian Sea, west coast of India, whereas its counterpart, the Bay ... -
Drifting and meandering of Olive Ridley Sea turtles in the Bay of Bengal: Role of oceanic Rossby waves
(Taylor & Francis, 2009)Olive Ridley turtles in the Bay of Bengal are previously thought to migrate southward from their nesting ground, along the east coast of India (Orissa coast), towards Sri Lanka. Surprisingly, three of the four Platform ... -
Life cycle of eddies along the western boundary of the Bay of Bengal and their implications
(Elsevier, 2012)Analysis of vertical thermohaline structure along the western boundary of the Bay of Bengal revealed many undulations during April–May 2003. A prominent feature noticed was a dome in the northwestern boundary of the Bay ... -
Mesozooplankton of the Arabian Sea: Patterns influenced by seasons, upwelling, and oxygen concentrations
(Elsevier, 2005)The intensive study of the Arabian Sea during the 1990s included mesozooplankton investigations by the Netherlands, United Kingdom, Pakistan, India, Germany and the United States. Several major discoveries resulted. First, ... -
Modelling tide-driven currents and residual eddies in the Gulf of Kachchh and their seasonal variability: A marine environmental planning perspective
(Elsevier, 2005)Tide-driven currents in the Gulf of Kachchh (GoK) have been studied using MIKE21 hydrodynamic model. The results are validated with measured currents for three different periods characterized by different wind fields. ... -
