A note on Arabian Sea warm pool and its possible relation with monsoon onset over Kerala
(IJSRP publisher, 2012)The possible relation of the Arabian Sea Warm Pool (ASWP) with monsoon onset over Kerala is studied by utilizing the TRMM Microwave Imager data during the period 2007-2011 (5 years). The ASWP is a part of the Indian Ocean ... -
An intrathermocline eddy and a tropical cyclone in the Bay of Bengal
(Nature Publishing Group, 2017)The Bay of Bengal, subjected to monsoonal forcing and tropical cyclones, displays a complex field of ocean eddies. On 5 December 2013 a sub-surface vortex or Intrathermocline Eddy (ITE) composed of water characteristic of ... -
Consequences of inhibition of mixed-layer deepening by the West India coastal current for winter phytoplankton bloom in the northeastern Arabian Sea
(American Geophysical Union, 2016)The intense winter phytoplankton bloom during November-February in the northeastern Arabian Sea (NEAS) was thought, until recently, to be controlled only by a convective deepening of the mixed layer (ML) owing to cool and ... -
Dominant role of winds near Sri Lanka in driving seasonal sea level variations along the west coast of India
(American Geophysical Union Publications, 2016)The strong seasonal cycle of sea level along the west coast of India (WCI) has important consequences for ecosystem and fisheries, and the Lakshadweep high/low in the southeast Arabian Sea is important for fisheries and ... -
Effect of submarine canyons on tsunami heights, currents and run-up off the southeast coast of India
(Current Science Association, 2016)Tsunami numerical model studies are mostly focused on inundation and run-up onto the coast. Fewer studies have been aimed at investigating role of submarine canyons on the tsunami heights, currents and run-up. The influence ... -
First evidence of denitrification vis-a-vis monsoon in the Arabian Sea since late Miocene
(Nature Publishing Group, 2017)In the Arabian Sea, South Asian monsoon (SAM)-induced high surface water productivity coupled with poor ventilation of intermediate water results in strong denitrification within the oxygen minimum zone (OMZ). Despite the ... -
Influence of Indian summer monsoon variability on the surface waves in the coastal regions of eastern Arabian Sea
(Copernicus, 2016)We assess the influence of monsoon variability on the surface waves using measured wave data covering 7 years and reanalysis data from 1979 to 2015 during the Indian summer monsoon (JJAS) in the eastern Arabian Sea. The ... -
Inhibition of mixed-layer deepening during winter in the northeastern Arabian Sea by the West India coastal current
(Springer, 2016)Though the deep mixed layers (MLs) that form in the northeastern Arabian Sea (NEAS) during the winter monsoon (November–February) have been attributed to convective mixing driven by dry, cool northeasterly winds from the ... -
Internal waves over the shelf in the western Bay of Bengal: A case study
(Springer, 2017)Generation and propagation of internal waves (IWs) in the coastal waters of the extended shelf of the western Bay of Bengal are investigated for late winter by using the Massachusetts Institute of Technology General ... -
Is sea-level rising?
(Ocean Society of India, 2016)There has been considerable research on sea-level-rise caused by global warming. The various reports of the Intergovernmental Panel on Climate Change (IPCC) made assessments of observed sea level rise and future projections. ... -
Longshore sediment transport in the surf zone based on different formulae: A case study along the central west coast of India
(Springer, 2017)Understanding longshore sediment transport (LST) is a prerequisite for designing an effective coastal zone management strategy. The present study estimates the LST along the central west coast of India based on four bulk ... -
Muddy waters
(ICSF, 2017)As mud banks along the southwest coast of India dwindle, several concerns and societal implications have been articulated regarding this unique oceanographic phenomenon -
Observations of long-period waves in the nearshore waters of central west coast of India during the fall inter-monsoon period
(Elsevier, 2017)The waves measured in the eastern Arabian Sea during the fall inter-monsoon period (October) are examined at 4 locations during 2010–2015. Multi-modal features have been observed in measured wave spectra due to independent ... -
Observed salinity changes in the Alappuzha mud bank, southwest coast of India and its implication to hypothesis of mudbank formation
(Elsevier, 2017)Alappuzha mud bank draws special attention among the twenty-mud bank locations reported along the Kerala coast by its remoteness from riverine sources. Among several hypotheses proposed for the formation of mud bank, the ... -
Positive Indian ocean dipole events prevent anoxia off the west coast of India
(European Geosciences Union, 2017)The seasonal upwelling along the west coast of India (WCI) brings nutrient-rich, oxygen-poor subsurface waters to the continental shelf, favoring very low oxygen concentrations in the surface waters during late boreal ... -
Relationship between summer monsoon rainfall and cyclogenesis over Bay of Bengal during post-monsoon (October-December) season
(Indian Academy of Sciences, 2016)In this study, an attempt has been made to examine the relationship between summer monsoon rainfall (June-September) and the total number of depressions, cyclones and severe cyclones (TNDC) over Bay of Bengal during the ... -
Seabed resident event driven profiling system (SREP). Concept, design and tests
(IEEE, 2016)The seabed resident event driven profiling system (SREP) described here offers a novel, optimized approach to profiling in coastal waters from seabed to sea surface during the rough seas encountered in the southwest monsoon ... -
Spatial and temporal variations of wave energy in the nearshore waters of the central west coast of India
(Copernicus Publications, 2016)Assessment of wave power potential at different water depths and time is required for identifying a wave power plant location. This study examines the variation in wave power off the central west coast of India at water ... -
Surface layer temperature inversion in the Bay of Bengal: Main characteristics and related mechanisms
(American Geophysical Union, 2016)Surface layer temperature inversion (SLTI), a warm layer sandwiched between surface and subsurface colder waters, has been reported to frequently occur in conjunction with barrier layers in the Bay of Bengal (BoB), with ... -
Suspended matter and fluid mud off Alleppey, southwest coast of India
(Elsevier, 2017)Time series measurements on suspended particulate matter (SPM) were made at one non-mud bank (M1) and two mud bank stations (M2 and M3) off Alleppey, south west coast of India. The mean SPM was low in surface (6.2 mg/l) ...
