    • Characterizing three shallow-water locations off Goa, India, using passive acoustic data 

      Chanda, K.; Chakraborty, B.; Mahale, V.; Latha, G.; Fernandes, W.A. (Acoustical Society of America (ASA), 2020)
      In this study, an analysis of the passive acoustic data is carried out for the quantitative characterization of shallow-water acoustic environments from three major estuarine systems of Goa during the months of March and ...
    • Fish Sound Characterization Using Multifractal Detrended Fluctuation Analysis 

      Chanda, K.; Shet, S.; Chakraborty, B.; Saran, A.K.; Fernandes, W.A.; Latha, G. (World Scientific Pub Co Pte Lt, 2020)
      This work involves the application of a non-linear method, multifractal detrended fluctuation analysis (MFDFA), to describe fish sound data recorded from the open waters of two major estuarine systems. Applying MFDFA, the ...
    • How biological (fish) noise affects the performance of shallow water passive array system 

      Fernandes, W.A.; Chakraborty, B.; Haris, K.; Vijayakumar, K.; Sundar, D.; Luis, R.A.A.; Mahanty, M.M.; Latha, G. (NIOT, Chennai, 2015)
      Passive acoustic data off Grand Island, Goa were acquired using a single wideband hydrophone system deployed at the water depth of ~20.5 m during the month of April, 2014. The 4- elements hydrophone array with an aperture ...
    • Humpback whale singing activity off the Goan coast in the Eastern Arabian Sea 

      Madhusudhana, S.K.; Chakraborty, B.; Latha, G. (2019)
      For over two decades, passive acoustic monitoring (PAM) methods have been successfully employed around the world for studying aquatic megafauna. PAM-driven studies in Indian waters have so far been relatively very scarce. ...
    • Multifractal approach for seafloor characterization 

      Chakraborty, B.; Haris, K.; Latha, G.; Maslov, N.; Menezes, A.A.A. (IEEE, 2014)
      This letter involves multifractal characterization of pockmark seepage associated seafloor along the central part of the western continental margin of India. Six representative blocks of backscatter and bathymetry coregistered ...
    • Passive acoustic metrics to understand shallow water biodiversity off Malvan area in the west coast of India 

      Chanda, K.; Chakraborty, B.; Vardhan, Y.V.; Gracias, D.; Mahanty, M.M.; Latha, G.; Fernandes, W.A.; Chaubey, A.K. (NISCAIR, 2020)
      Underwater soundscape monitoring is an effective method to understand the biodiversity of an ecosystem. In this context, quantitative characterization of shallow water soundscape of the Burnt Island located off Malvan area ...
