A brief report on mets system
(National Institute of Oceanography, 2005)Mets system is basically a gas monitoring system, used for the detection of underwater gas. The system consists of a sensor, datalogger and energy module. The sensor works on the diffusion techniques. The system can be ... -
A method of transferring G.T.S. benchmark value to survey area using electronic total station
(National Institute of Oceanography, India, 2007)A G.T.S. (Great Trigonometrical Survey) benchmark is a permanently fixed reference survey station (or point), having known elevation with respect to a standard datum (mean sea level). These are established all over India ... -
A method to eliminate refraction artifacts in EM1002 multibeam echosounder system (Swath bathymetry and seabed surveys of EEZ)
(National Institute of Oceanography (CSIR); Dona Paula, Goa; India., 2011)The multi-beam echo-sounder systems acquire bathymetry data with additional information. This supplementary data along with proper bathymetry can be further used in scientific studies. As observed most of the multi-beam ... -
A numerical wave prediction model dolphin: Theory and test results
(1985)This report gives the basic theory of ocean waves and ocean wave prediction and a description of the physical background and of tests of the wave hindcast model Dolphin -
A program to compute geographical positions of underwater artifact based on linear measurements
(National Institute of Oceanography, India, 2004)While carrying out underwater positioning in shallow waters, the Diver Archaeologists measure lengths and bearings from a base line of the well-established control network to each and every corner of the artifact. A program ... -
Air-Sea Coupling Over The Equatorial Indian Ocean
(2007)The present work aims at understanding the upper ocean variability of the EIO on a seasonal scale and then to explore the atmospheric forcing responsible for it.To achieve the objective, the Equatorial Indian Ocean between ... -
Algorithms and interface for ocean acoustic ray-tracing (Developed in MATLAB)
(National Institute of Oceanography, 2005)An integrated friendly-user interactive ocean application package has been developed for computation of eigenrays for a given source - receiver configuration and subsurface and bottom environmental conditions utilizing the ... -
An algorithm for determination of geodetic path for application in long-range acoustic propagation
(NIO, Goa, 1993)A computer program has been developed for the construction of geodetic path between two points on the spheroidal surface for application in long range acoustic propagation in the ocean. Geodetic equations have integrated ... -
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 ... -
An atlas of mean distribution of precipitable water vapour over the tropical Indian Ocean for the year 1979
(1993)The monthly mean maps of the precipitable water (PW) over the tropical Indian Ocean are prepared using the data derived from the Nimbus 7 Scanning Multichannel Microwave Radiometer (SMMR) sensor for the period January to ... -
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 ... -

Analysis of chlorophyll pigment concentration in the northern Arabian Sea using remote sensing and GIS
(2007)The phytoplankton in the ocean plays an important role not only because it produces food that sustains the marine life, but also it is capable of regulating CO2 and there by influencing the climate of the earth system. It ... -
Application of generalized inverse for analysis of magnetic anomalies due to a dyke model - Some numerical experiments
(National Institute of Oceanography, 2005)Forward and inverse methods of magnetic interpretation have been used to estimate the parameters of dyke like intrusion over the eastern continental shelf of India. In the forward problem, the tentative parameters of the ... -
Application of neural networks in coastal engineering
(National Institute of Technology Karnataka, India, 2003)Neural networks have the ability to recognize the hidden pattern in the data and accordingly estimate the output values. Provision of model-free solutions, data error tolerance, built in dynamism and lack of any exogenous ...
