Drifting buoys (DBs) are widely deployed to observe near-surface ocean currents and sea surface temperature. The National Institute of Ocean Technology (NIOT), Chennai, India, had indigenised the DB with the Indian satellite (INSAT) in 2012. This paper describes the results of various studies conducted by NIOT using the indigenised DBs and also describes unique features attempted in indigenised DBs...
Drifting buoys are widely deployed to measure near surface ocean currents and temperature. The Global Ocean Observation System program designed a global array of 1250 drifter buoys to cover oceans at resolution of one per 5° × 5° grids spatially. The National Institute of Ocean Technology, India indigenized drifting buoy in 2012 with geostationary satellite communication to have near real-time data...

An indigenously developed Buried Object Detection SONAR (BODS) for finding targets in the seabed is described in this paper. The important features of BODS are wide bandwidth (2–24 kHz), light weight projector (21 kg) and computer based real time signal processing. The results from experiments at shallow waters to detect seabed boundary layer and targets like metal plate and concrete blocks, are also...
Indian Ocean has an important role in regional and global climate due to its geography. Presently, variety of ocean observation instruments are employed to measure time and space variability of the large ocean that extends to two closed bays at higher latitudes. Underwater gliders are recently considered to be a vital platform for ocean observation. The revolutionary new underwater glider (“Barathi”),...
A systematic approach in implementing a suitable validation method which evaluates a newly developed product is highly necessary to ensure its continuous reliability and consistency of its quality[1] performances. More specifically any sensor or instrument developed for the real time data collection and measurement of ocean parameters need to be prejudged and evaluated for its data product quality...
Indian Tsunami Warning System was established in 2006 by National Institute of Ocean Technology (NIOT), Chennai, Ministry of Earth Sciences, Government of India. It comprises of Data Buoys with Bottom Pressure Recorders in the deep seabed and Acoustic Tide Gauge Network in the coastal areas. This paper describes design and field trials of an Advance Tide Gauge for Tsunami monitoring applications in...
A minor change in any one of the ocean parameters, results in a major climatic variation over large areas of Earth. National Institute of Ocean Technology (NIOT) as technical arm of MoES established National Data Buoy Programme (NDBP) in 1997. A solar powered 2.2m discus type data buoy was indigenously developed at NIOT under this programme in 2004. The data buoys were instrumented to measure various...
