“…The Integrated Marine Surveillance System (IMSS) implemented in the Indian moored buoy programme is the first of its kind, using an approach that provides real-time meteorological and oceanographic data via 3G telemetry and/or general packet radio service (GPRS; Venkatesan 2014). An uninterrupted power source is required to run all the sensors working at sea, which are unattended for long periods; with this in mind, NIOT developed wind-powered buoys (Kesavakumar et al 2013). To study Polar-Indian monsoon teleconnections, a multi-sensor moored observatory was deployed in the Arctic region (PIB GoI 2014).…”

Ocean-atmosphere interactions in the North Indian Ocean play a vital role in the onset, progression and withdrawal of the Indian monsoon. This paper describes the Ocean Observation System (OOS), an operational observational programme of the Earth System Science Organization and the National Institute of Ocean Technology (ESSO-NIOT) under India's Ministry of Earth Sciences (MoES). Since 1997 it has provided oceanographic and surface meteorological data in real time for weather forecasting, climate research and several other applications. The programme focuses on understanding the phenomenon of the mean seasonal cycle of the Indian monsoon, the intra-seasonal to intra-decadal oscillations of air-sea interactions, trends that are related to tropical cyclones and the annual cycle balance in the exchange of waters between the two limbs of North Indian Ocean, i.e. the Arabian Sea and the Bay of Bengal. In situ observations are also used to develop, initialise and validate regional forecast models that provide high resolution data. There is also a growing need to understand the spatial phenomenon of oceans using satellite observations, wherein the quality of data needs to be validated and verified carefully. This paper also provides an overview of the scientific and societal impact of the Indian moored buoy network over two decades of operation. ARTICLE HISTORYHistorically, ocean surface measurements have been made via ships of opportunity, cargo vessels that sail the oceans to conduct maritime trade. These measurements were made for the safety of the ships' navigation,

A B S T R A C TThis paper details the evolution of reliable and cost-effective data buoy power systems used for environment monitoring applications in the Indian seas. A reliable power system is the key requirement for offshore moored buoys involved in meteorological and tsunami monitoring missions, as unavailability of the operating power results in loss of time-critical data and can have serious impact on societal protection and, in addition, results in costly repairs and reinstallations. As a significant development and driven by stringent IEC 61508 Safety Integrity Level (SIL) standards, a Generation III power system was able to meet the required SIL 4 reliability requirements compared to the Generation I system that complied only with SIL 1. It is found that by using a suggested four slot annual maintenance plan, an operating Generation III hybrid power system, and lead acid batteries powered by solar energy and backed by Lithium thionyl chloride batteries, in addition to meeting the required SIL 4 reliability levels, the energy cost of transmission is reduced to U.S. $1.7 per data set, compared to U.S. $2.7 in the Generation II systems. Ongoing efforts in increasing the green footprint in futuristic systems are detailed. The study provides confidence in the power system's reliable, cost-effective and eco-friendly support to India's Ocean Observation Network program.

“…In addition, the SWB is relatively recently developed compared to LIB, those data-based SOH estimation works for the SWB are rarely reported. Lastly, under marine environments, the buoy needs to be self-powered with harvesting devices such as PV [34], wind [35] and wave harvester [36] for longlasting system operation. Also, intelligent power management techniques are required, since the buoy lightening causes large power consumption.…”

This paper presents a wireless marine buoy system based on the seawater battery (SWB), providing self-powered operation, power-efficient management, and degradation prediction and fault detection. Since conventional open circuit voltage (OCV) methods cannot be applied due to inherent cell characteristics of SWB, the coulomb counting (CC) method is adopted for the state of charge (SOC) monitoring. For the state of health (SOH), a variance-based detection scheme is proposed to provide degradation prediction and fault detection of the SWB. The self-powered operation is augmented by two proposed power optimization schemes such as multiple power management and three-step LED light control. A wireless buoy system prototype is manufactured, and its functional feasibility is experimentally verified, where its location and SOC are periodically monitored in a smartphone-based wireless platform.
