Over-estimation of sea level measurements arising from water density anomalies within tide-wells - A case study at Zuari Estuary, Goa
(The Coastal Education and Research Foundation, 2002)
A 3-year study of water density anomalies within a conventional tide-well indicated that the average water density within the well was consistently lower than that of the external ambient waters. The tide-well at Marmugao, ...
Measurements of sea level off Tikkavanipalem - Coast India
(Allied, Chennai, 2001)
Sea level and meteorological measurements have been made, off Tikkavanipalem coast in Andhra Pradesh, India in 1997-98. Sea level measurements were made in four temporal segments of one-month duration each during a one-year ...
Development of an autonomous vertical profiler for oceanographic studies
(Allied, 2007)
The variations in oceanic variables that influence global climate, hypoxia in freshwater reservoirs and in coastal waters as in the west coast of India, the rise of harmful algal blooms are amongst current problems that ...
Control of the Maya AUV in the vertical and horizontal planes: Theory and practical results
(Institute for Systems and Robotics, 2007)
The paper describes the design and testing of the depth and heading autopilots for a small Autonomous Underwater Vehicle (AUV) named Maya. Control system design is done using the LQ (Linear-Quadratic) optimization technique ...
Miniature sonar for obstacle detection on samll AUV Maya
(Allied, 2007)
Autonomous platforms are increasingly able to collect in-situ data with least disturbance to the parameters under measurements. To attain high level of autonomy they need to posses capabilities to detect and avoid obstacles ...
Design and development of pressure sensor based on Fiber Bragg Grating (FBG) for ocean applications
(EDP Sciences, 2020)
Reactively evaporated TiO2 thin films were deposited on the glass substrate by electron beam heating technique. In the first stage evaporation rates are varied keeping substrate temperature fixed at 200 C and oxygen flow ...
A technique to circumvent lower density water trapping by tide-wells
(Cochin Univ. of Sci. and Technol., Cochin, India, 1999)
A 3-year study of water density differences inside and outside of a conventional tide-well indicated that the average water density within the well is consistently lower than the external ambient waters. The tide-well at ...
Assessment of heavy metals in the sediments of anthropogenically disturbed patalganga estuary, india
(EM International, Pune, 2020)
The present study aims to evaluate the effect of industrialization on the heavy metal accumulation in sediments of the Patalganga Estuary. The contamination level of the Patalganga estuary is evaluated based on the enrichment ...
Experience with Downward-looking Aerial Microwave Radar Based Sea-level Gauges deployed along Indian Coasts and Islands
(Intergovernmental Oceanographic Commission of UNESCO, Paris, 2016)
Subsequent to the disastrous December 2004 Indian Ocean tsunami event, near real-time reporting integrated coastal observation network (ICON) providing sea-level, sea-state and surface meteorological information has been ...
The detection of annual hypoxia in a low latitude freshwater reservoir in Kerala, India, using the small AUV Maya
(Marine Technology Society, 2009)
The Idukki Reservoir at an altitude of 748 m covering an area of 53 km sup(2) is surrounded by tropical forests in the Western Ghats in the southwestern Indian state of Kerala. We used the small autonomous underwater vehicle ...
