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 ...
Mechanisms of barrier layer formation and erosion from in situ observations in the Bay of Bengal
(2019)
During the Bay of Bengal (BoB) Boundary Layer Experiment (BoBBLE) in the southern BoB, time series
of microstructure measurements were obtained at 88N, 898E from 4 to 14 July 2016. These observations
captured events of ...
Augmented coral reef monitoring using a stationary reef monitoring system
(Elsevier, 2023)
Coral reef monitoring is a reliable tool to assess the effect of climate change as corals are sensitive to increases in water temperatures between 30 �C and 35 �C resulting in bleaching - a whitening process when the corals ...
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 ...
Installation and operation manual on sea level gauge (Model: NIO_Ghana_2004)
(National Institute of Oceanography, India, 2004)
NIO sea level gauge is a pressure-based gauge that operates on 12 volts battery. The pressure-sensing element used in this gauge is a piezo-resistive programmable semiconductor transducer that provides pressure samples in ...
