Ocean Acoustic Waveguide Remote Sensing: Visualizing Life Around Seamounts [PDF]

Oceanography, 2010
Collectively, seamounts form a significant biome the size of Europe with important but heavily depleted fisheries (see Etnoyer et al., 2010). Recently, large seamount tracts have been put aside as protected areas (see Pitcher et al., 2010).

Sampling mobile oceanic fishes and sharks: implications for fisheries and conservation planning [PDF]

, 2017
Tuna, billfish, and oceanic sharks [hereafter referred to as ‘mobile oceanic fishes and sharks’ (MOFS)] are characterised by conservative life-history strategies and highly migratory behaviour across large, transnational ranges. Intense exploitation over

Investigating the build-up of precedence effect using reflection masking [PDF]

, 2006
The auditory processing level involved in the build‐up of precedence [Freyman et al., J. Acoust. Soc. Am. 90, 874–884 (1991)] has been investigated here by employing reflection masked threshold (RMT) techniques.

Maximum Likelihood Deconvolution of Beamforming Images with Signal-Dependent Speckle Fluctuations

Remote Sensing
Ocean Acoustic Waveguide Remote Sensing (OAWRS) typically utilizes large-aperture linear arrays combined with coherent beamforming to estimate the spatial distribution of acoustic scattering echoes. The conventional maximum likelihood deconvolution (DCV)
