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 ... -
Mechanical design and development aspects of a small AUV - Maya
(Institute for Systems and Robotics, 2007)This paper contains a description of the mechanical design route that was adopted in building a small AUV (Autonomous Underwater Vehicle). At the outset, it is decided to follow a set of guidelines that defined a broad set ... -
Will the aerosol derived from the OCM satellite sensor be representative of the aerosol over Goa?
(Indian Aerosol Science and Technology Association, 2007)Most of the ocean color satellite sensors such as IRS-P4 OCM, SeaWiFS and MODIS are sun synchronous and have pass over the regions during noon. From our measurements of aerosol optical properties using five-channel ... -
Neural network-genetic programming for sediment transport
(Institution of Civil Engineers, 2007)The planning, operation, design and maintenance of almost all harbour and coastal engineering facilities call for an estimation of the longshore sediment transport rate. This is currently and popularly done with the help ... -

Stability analysis of rubblemound breakwater using ANN
(National Institute of Technology, Surathkal, 2007)The stability analysis of coastal structure is very important because it involves many design parameters to be considered for the safe and economical design of structure. In the present study neural network technique is ... -
An approach towards solving refraction problems in EM1002 multi-beam echo-sounder system
(National Institute of Oceanography, India, 2007)Multi-beam echo-sounding is the technique in which multiple beams of acoustic in nature are sent down to seabed and upon reflection, they are received back and processed to give depths values. The report is focused to give ... -
Impact of bathymetric system advances on hydrography

Vulnerability of Cochin Backwaters to meteorological disturbances with special reference to tidal propagation
(School of Naval Oceanology and Meteorology, 2007)Features of water level oscillation in the Cochin backwaters are presented in relation to its vulnerability to meteorological disturbances. A steep surge formed after a sharp atmospheric depression (8 mb) followed by storm ... -
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 ... -
Environmental magnetic studies on some Quaternary sediments of varied depositional settings in the Indian sub-continent
(Elsevier, 2007)The efficacy and limitations of routine environmental magnetic approaches to characterize and compare the Quaternary sediments of varied depositional settings (fluvial, fluvio-lacustrine and marine) from the Indian ... -
Tsunamis and marine life
(Taylor and Francis, 2007)The 26 December 2004 tsunami in the Indian Ocean exerted far reaching temporal and spatial impacts on marine biota. Our synthesis was based on satellite data acquired by the Laboratory for Tropical Marine Environmental ... -
Bacterial contribution to mitigation of iron and manganese in mangrove sediments
(Elsevier, 2007)The Mandovi and Chapora, (Goa, India) are two tropical estuaries lying in close geographic proximity on the west coast of India. Seasonal changes in down core variation of Fe, Mn and Total Organic Carbon (TOC) in the ... -
Double reductive cyclization: A facile synthesis of the indoloquinoline alkaloid cryptotackieine
(Elsevier, 2007)A new synthesis of the indoloquinoline alkaloid cryptotackieine, isolated from Cryptolepis sanguinolenta, is described which involves a Perkin reaction, a tandem double reduction-double cyclization reaction followed by ... -

Life history and population dynamics of an estuarine amphipod, Eriopisa chilkensis Chilton (Gammaridae)
(Elsevier, 2007)The life cycle of the gammarid amphipod Eriopisa chilkensis Chilton from the Cochin estuary, south west coast of India, has been studied for the first time under laboratory conditions. Amphipods, especially gammarids, are ... -
A new genus and species of Heteromysini (Crustacea- Mysidacea) from the backwater of Kochi (Kerala, India)
(Taylor and Francis, 2007)Kochimysis pillaii, a new genus and species of Heteromysini collected from the backwater of Kochi (Kerala, India), is described. The new genus is closely related to the genus Deltamysis but is distinguishable from the ... -
Docosahexaenoic acid accumulation in hraustochytrids: Search for the rationale
(Springer, 2007)Thraustochytrid protists characteristically accumulate high amounts of lipids, much of which is comprised of the polyunsaturated fatty acid, docosahexaenoic acid (DHA). Since DHA is important in human health, thraustochytrids ... -
Biodiversity of benthic polychaetes from the coastal waters of Paradip, Bay of Bengal
