A small autonomous surface vehicle for ocean color remote sensing
(IEEE, 2007)This paper provides a study on the development and the use of a small autonomous surface vehicle (ASV) that automatically follows programmed mission transects, while measuring sensor outputs along the tracks. It discusses ... -
Acoustic remote sensing of ocean flows
(Narosa, New Delhi (India), 1997)Acoustic techniques have become powerful tools for measurement of ocean circulation mainly because of the ability of acoustic signals to travel long distances in water, and the inherently non-invasive nature of measurement. ... -
Air sea interaction during summer monsoon period of 1979
(Seibutsu Kenkyusha Co.; Tokyo; Japan, 1993)The present study highlights the utility of satellite derived parameters like SST, precipitation, CMV winds in the lower troposphere etc. in supplementing the in-situ observations. This information can lead to a better ... -
Air-sea coupling during the tropical cyclones in the Indian Ocean: A case study using satellite observations
(Birkhauser Verlag, 2005)In the years 1999 and 2001,three intense tropical cyclones formed over the northern Indian Ocean - two over the Bay of Bengal during 15 -19 and 25 -29 October, 1999 and one over the Arabian Sea during 21 -28 May, 2001. We ... -
An empirical algorithm to estimate spectral average cosine of underwater light field from remote sensing data in coastal oceanic waters.
(Association for the Sciences of Limnology and Oceanography, 2014)The underwater average cosine is an apparent optical property of water that describes the angular distribution of radiance at a given point in water. Here, we present a simple empirical algorithm to estimate spectral ... -
An interactive software package for validating satellite data
(Universidad de Concepcion, 2004)Earth observation satellite launched in the last three decades have made vital contributions to the understanding of the planet. The earth system consisting of land, oceans and atmosphere is linked together by a number of ... -
Application of remote sensing and GIS for the demarcation of groundwater potential zones of a river basin in Kerala, southwest coast of India
(Taylor and Francis, 2007)An integrated hydrogeological investigation has been made to delineate the groundwater-potential zones of the Muvattupuzha river basin, Kerala, along the southwest coast of India. The basin is characterized by charnockites ... -
Application of remote sensing technology for studying littoral sediment dynamics
(Publ. and Inf. Dir., New Delhi, India, 1994)Satellite remote sensing data pertaining to two areas, one each on east and west coasts of India has been utilized to study suspended sediment dynamics within the near-shore region. For this purpose, thematic mapper image ... -
Assessment of the land use/land cover (LU/LC) and mangrove changes along the Mandovi–Zuari Estuarine complex of Goa, India
(Springer, 2015)Land use/land cover change dynamics along the estuarine complex of Mandovi–Zuari in the coastal state of Goa, India is studied by the application of multi-temporal remote sensing data. This tropical estuarine region has ... -
Change detection studies of Sagar Island, India, using Indian Remote Sensing Satellite 1C linear imaging self-scan sensor III data
(The Coastal Education and Research Foundation, 2007)The coastal zone of Sagar Island, West Bengal, India, is subjected to various cyclic and random processes that continuously modify the region. The shoreline and land-use/land cover changes have been studied using Indian ... -
Chlorophyll and sediment distribution study of the Gulf of Kutch using remote sensing
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)This study is largely based on the resulting series of SeaWiFS images and OCM images of Gulf of Kutch, which shows chlorophyll distribution on about 160 (cloud-free) dates between October 1998 and August 2001 period and ... -
Chlorophyll modulation of sea surface temperature in the Arabian Sea in a mixed-layer isopycnal general circulation model
(American Geophysical Union, 2000)Remotely sensed chlorophyll pigment concentrations from the Coastal Zone Color Scanner (CZCS) are used to estimate biological heating rate and investigate the biological modulation of the sea surface temperature (SST) in ... -
Coastal geomorphology and land use changes along coastal parts of Goa: An RS-GIS approach
(GSDI Association, 2012)GOA, endowed with natural & scenic beauty, is famous for its silvery sand & golden coastline. In the recent years, a lot of changes (both natural & man-made) have occurred rapidly which have direct impact on the human ... -
Comparison of sea-level measurements between microwave radar and subsurface pressure gauge deployed at select locations along the coast of India
(SPIE, 2013)Sea-level data are obtained from several remote and coastal locations using absolute pressure gauges deployed at known level, known as chart datum. However, to yield correct sea-level measurements from absolute pressure ... -
Comparison of wind data from QuikSCAT and buoys in the Indian Ocean
(Taylor and Francis, 2007)The performance of QuikSCAT-derived wind vectors is evaluated using in-situ data from moored buoys over the Indian Ocean. The results show that the mean differences for wind speed and wind direction are 0.37 ms sup(-1) and ... -
Culturable bacterial flora associated with the dinoflagellate green Noctiluca miliaris during active and declining bloom phases in the Northern Arabian Sea
(Springer, 2013)A massive algal bloom of the dinoflagellate Noctiluca miliaris (green) was located in the Northern Arabian Sea by IRS-P4-2 (OCM-II) for microbiological studies, during two consecutive cruises of February-March 2009. ... -
