Ocean Observing System


A comprehensive ocean observation network program had been launched for the understanding of structure and dynamics of ocean, improving the predictability of ocean and climate, for the sustainable development of coastal ecosystem and for the generation of ocean information and advisory services. The ocean observing systems, currently in operation can be broadly classified as (i) in-situ observation systems that capture the changes in time at specific locations or along the ship tracks, (ii) the satellite-based remote sensing systems that capture the spatial and temporal variations, synoptically, as ramified at the surface and sub-surface. During the period, significant progress has been made in the ocean observing systems, with a mix of in-situ platforms and satellite systems and concomitant capabilities in retrieval of data. Moored data buoys with subsurface sensors up to 500m depth, besides surface sensors, were deployed in Bay of Bengal and continuous measurements have been made. Also data buoys and tsunami buoys are developed indigenously. The details of deployment against planned so far in the plan period are as follows:

Type of Platform Target Commissioned till February, 2016 Data received during February, 2016
Argo Float 200 322 153
Drifters 150 108 4
Moored Buoys 16 20 20
Tide Gauges 36 34 27
High Frequency(HF) Radars 10 10 10
Current Meter Array 10 11 2
Acoustic Doppler Current Profiler(ADCP) 20 20 15
Tsunami Buoys 7 9 6
Wave Rider Buoy 16 17 9

* The remaining floats/drifters have completed their life time and as such no data can be received from them.
