BUOY NETWORK Met Ocean Buoy The Moored data buoys are floating platforms, which carry sensors to measure Wind Speed & Direction, Atmospheric Pressure, Air Temperature, Humidity, Conductivity, Sea Surface Temperature, Current Speed & Direction and Wave Parameters. The buoys are equipped with global positioning system, beacon light & satellite transceiver. Lithium battery pack is used for supplying power to the entire buoy system. Few buoys are designed to carry additional sensors to measure water quality parameters and subsurface temperature. Omni Buoy The OMNI buoys are Moored Buoy Network in Northern Indian Ocean and are more similar to data buoys but have the capability to measure Ocean Current, Conductivity and Temperature up to 500m depth and transmit hourly data through satellite. In addition, these buoys are also equipped with Radiation sensors and Rain Gauges too Tsunami Buoy As challenges arise in the form of natural disasters and in spite of infrequent occurrence of Tsunamis in the Indian Ocean, which could occur anytime and could be very devastating. OOS team has developed, tested and have established Tsunami Buoy system with Bottom Pressure Recorder (BPR) in Indian Seas. The Tsunami buoy systems consist of two units, a surface buoy and the Bottom Pressure Recorder (BPR). Communication between BPR and the surface buoy is established through acoustic modems and surface buoys uses satellite to communicate the recorded values to shore station. During normal condition, the BPR measures the pressure every 15 seconds and communicates it to the surface buoy every hour with four 15 minute averaged water level values. The surface buoy in turn transmits the data to the shore station. In the event of a Tsunami, the BPR measures the pressure and communicates it to the surface buoy every 5 minutes with ten 30 second water level values. The surface buoy transmits the data to the shore station every 5 minutes for 3 hours. Coastal Buoys A buoy equipped with meteorological and Oceanographic sensors along with water quality sensors is deployed at Mahatma Gandhi Marine National Park, Wandoor, Andaman & Off Agatti at Lakshadweep Islands. ARTIC OBSERVATORY First Indian ARCTIC observatory IndARC The mooring system designed in such a way it is capable to withstand for an year Sensors fitted to measure conductivity, Temperature, dissolved oxygen, Pressure, Current speed, Current Direction, Nitrate, Photosynthetically Active Radiation (PAR), Fluorosence, Turbidity, Ambient noise etc., The design, development and installation of this underwater moored observatory were successfully executed by OOS-NIOT in collaboration with NCAOR, Goa.

This in-house design effort to withstand harsh polar weather is a milestone achievement for the MoES and India. One of the major constraints in such a study has been the difficulty in reaching the location during the harsh Arctic winter and obtaining near-surface data. The IndARC observatory is an attempt to overcome this lacuna and collect continuous data from depths very close to the surface waters as well as at different discrete depths. Increased understanding of the response of the Arctic to climatic variability, the data would also enable our understanding of the Arctic processes and their influence on the Indian monsoon system through climate modelling studies. Received National Geo Science Award for the first ARCTIC observatory TECHNICAL DEVELOPMENTS Prakruthi Indigenous deep sea instrumented buoy system. It is capable of sending 106 parameters in real time. Interfaced with subsurface sensors, ADCP, DVS, wave, Irradiance, Radiation etc., Indigenous Tsunami buoy system ITBS will avoid the technology dependency and provides the capacity to upgrade, improve the tsunami buoy system in house. The development includes tsunami surface buoy systems with next Generation buoy hull, Low Power Integrated Data Acquisition Module (LIDS) and Indigenized BPR. The designed buoy has proved that it is stable and safe. The Indian Tsunami Buoy and BPR system – ‘Sagar Bhoomi’ was tested and deployed successfully in Bay of Bengal at depth of 3320m. Patent published in Indian Patent journal titled “Real Time Tsunami Monitoring System”, Application No. 2301\\CHE\\2014 dated 2014 Cyclone-Rapid Mode Data Collection Pressure and wind are the prime parameters need to be concentrated during cyclone and low pressure. Increasing the transmission rate during cyclone helps to observe the changes. The rapid mode cyclone detection algorithm utilizes the pressure gradient during cyclone passage and triggers data transmission at every one hour, whereas the normal transmission rate is once in every three hours. Patent published in Indian Patent journal titled “A System And Method For Rapid Mode Transmission During Cyclone” Application Number : 201641045091

Integrated Marine survillance system (IMSS) IMSS is designed to capture the met-ocean data including video footage information about passing by ships and to continuously transmit data to shore. The innovation also has facilities for two way communication to modify sampling and transmission intervals. Meteorological data is instantaneously shared with IMD for weather forecast and cyclone warning. The novelty of the system is introduction of surveillance and vessel identification system using floating buoy technology with suit of meteorological and oceanographic sensors interfaced to a common data acquisition system. Patent published in Indian Patent journal titled “An apparatus and the functioning of integrated marine surveillance systems”. NO: 873/CHE/2012 Roboboat “Sagar Avalokan” A remotely operable surface sampling system has been successfully tested at high seas during the year 2017 onboard Sagar Nidhi. The data collected include Sea Surface Temperature (SST). The boat was operated close to 500m in the vicinity of the ship. Functionality tests included stability, micro controller, thruster and other electronic assembly checks along with the remote control operation. In addition, a camera was also mounted and video footages were also captured from the boat and obtained through Wi-Fi on onboard mobile phones. Augmenting additional sensors and controls can also be done. Chatur Submerged tsunami surface buoy system (CHATUR) was tested successfully at sea at a depth of 360 m during the year 2017. In CHATUR, conventional surface buoy component is replaced by a submerged platform, which is secured from storms and surface traffic. At tsunami event, it ascends to the surface for transmission.
