Popis: Ayyadurai, T.; Raguraman, G.; Ashokan, M., and Latha, G., 2020. Ambient noise measurement system for the Arctic region. In: Sheela Nair, L.; Prakash, T.N.; Padmalal, D., and Kumar Seelam, J. (eds.), Oceanic and Coastal Processes of the Indian Seas. Journal of Coastal Research, Special Issue No. 89, pp. 67-70. Coconut Creek (Florida), ISSN 0749-0208.Ambient noise measurements in the polar region are challenging due to the ice-covered environment and very low temperature prevailing in the region. The primary aim of this research work is to design and develop a system capable of associated components to withstand harsh environments, such as the Arctic region. This system consists of a hydrophone, a data acquisition system and a battery pack placed in an indigenously developed underwater pressure casing. While the water depth is 190 m, the noise measurement system is placed at a depth of 30 m. The objective of this work is to record the time series of ocean ambient noise in the Kongsfjorden fjord, Arctic region, covering the seasonal cycle and study the sea ice dynamics and biological noise.
