A quality-control procedure for surface temperature and surface layer inversion in the XBT data archive from the Indian Ocean
(American Meteorological Society, 1999)A quality control procedure has been developed and validated for Expendable Bathythermograph (XBT) data from Indian Ocean archieved at Indian Oceanographic Data Centre (IODC). Two possible sources of errors are considered ... -
A study of marine ambient acoustic noise in relation to marine life in Antarctic waters during austral summer of 18 th Indian Expedition to Antarctica (1998-99)
(Department of Ocean Development; New Delhi; India, 2002)The exploration of the Antarctic Ocean (Southern Ocean) receives much attention by Oceanographers of various disciplines, because the ocean supports all the animal life and has the tremendous influence on meteorology and ... -
An atlast of XBT thermal structures and TOPEX/POSEIDON sea surface heights in the north Indian Ocean
(National Institute of Oceanography, India, 2003)The National Institute of Oceanography (NIO), Goa, India has been taking a leading role in the in situ data collection and analysis for several years. In this atlas the temperature profiles collected by a dedicated team ... -
An evaluation of XBT depth equations for the Indian Ocean
(Pergamon, 1998)For the purpose of finding XBT depth equations applicable to the entire Indian Ocean experiments were carried out through the collection of controlled XBT-CTD data on four cruises. These experiments were conducted in various ... -
An interactive graphical system of XBT data quality control and visualization
(Pergamon, 2001)A PC-based system has been developed for quality control and visualization of expendable bathy thermograph (XBT) data archived at the Indian Oceanographic Data Centre. The system, coded in Visual C++, is user interactive ... -
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 ... -
Investigation of XBT and XCTD biases in the Arabian Sea and the Bay of Bengal with implications for climate studies
(American Meteorological Society, 2011)Long time series of XBT data in the Bay of Bengal and the Arabian Sea are valuable datasets for exploring and understanding climate variability. However, such studies of interannual and longer-scale variability of temperature ... -
Observed interannual variability of the thermohaline structure in the south eastern Arabian Sea
(Springer, 2011)The XBT and sea surface salinity (SSS) measurements systematically carried out at near-fortnightly interval from May 2002 to August 2008 in the South Eastern Arabian Sea (SEAS) are utilised to describe the observed seasonal ... -
Observed variability of sea surface salinity and thermal inversions in the Lakshadweep Sea during contrast monsoons
(AGU, 2005)The sea surface salinity (SSS) of the Lakshadweep Sea (LS) shows large seasonal variability due to horizontal advection of low (high) salinity waters from south (north) during winter (summer) monsoon. The measurements made ... -
XBT fall rate in waters of extreme temperature: A case study in the Antarctic Ocean
(American Meteorological Society, 2002)XBT fall-rate variation in waters of extreme temperature and the resulting depth error has been addressed using controlled XBT-CTD datasets collected from two cruises in the Southern Ocean. Mean depth errors deduced from ...
