    • A Century of Sonar: Planetary Oceanography, Underwater Noise Monitoring, and the Terminology of Underwater Sound. 

      Ainslie, Michael A. (2015)
      The current terminology of underwater sound, as documented, for example, by (Urick, 1983), was developed during and after the Second World War (ASA, 1951; Urick, 1967), and has evolved little since then (Jensen et al., ...

    • A comparison of three methods for estimating call densities of migrating bowhead whales using passive acoustic monitoring. 

      Oedekoven, Cornelia; Marques, Tiago A.; Harris, Danielle; Thomas, Len; Thode, Aaron M.; Blackwell, Susanna B.; Conrad, Alexander S.; Kim, Katherine H. (2022)
      Various methods for estimating animal density from visual data, including distance sampling (DS) and spatially explicit capture-recapture (SECR), have recently been adapted for estimating call density using passive ...

    • Management and research applications of real-time and archival passive acoustic sensors over varying temporal and spatial scales. 

      Van Parijs, Sofie; Clark, Chris W; Sousa Lima, Renata; Parks, Susan; Rankin, Shannon; Risch, Denise; Van Opzeeland, Ilse (2009)
      Defining the appropriate scale over which to conduct a study in the marine environment is critical to achieving appropriate scientific, management, mitigation and conservation objectives. This paper focuses on applications ...

    • Management of acoustic metadata for bioacoustics. 

      Roch, Marie A.; Batchelor, Heidi; Baumann-Pickering, Simone; Berchok, Catherine L.; Cholewiak, Danielle; Fujioka, Ei; Garland, Ellen C.; Herbert, Sean; Hildebrand, John A.; Oleson, Erin M.; Van Parijs, Sofie; Risch, Denise; Sirovic, Anna; Soldevilla, Melissa S. (2016)
      Recent expansion in the capabilities of passive acoustic monitoring of sound-producing animals is providing ex- pansive data sets in many locations. These long-term data sets will allow the investigation of questions ...

    • Modelled Mapping of Continuous Underwater Noise Generated by Activities. 

      Marine Management Organisation; ABP Marine Environmental Research Ltd (ABPmer) (Marine Management Organisation, 2015)
      This report on underwater noise in the South marine plan areas has been prepared by ABP Marine Environmental Research Ltd (ABPmer) on behalf of the Marine Management Organisation (MMO). Quantification of underwater noise ...

    • Particle motion: the missing link in underwater acoustic ecology. 

      Nedelec, Sophie L.; Campbell, James; Radford, Andrew N.; Simpson, Stephen D.; Merchant, Nathan D. (2016)
      1. Sound waves in water have both a pressure and a particle-motion component, yet few studies of underwater acoustic ecology have measured the particle-motion component of sound. While mammal hearing is based on detection ...

    • Quality Control of Lidar Data, Version 1.0. 

      Geijsels, Sarah (Channel Coastal Observatory, National Oceanography Centre, Southampton UK, 2017)
      An important driver for the Regional Coastal Monitoring Programmes is that all data collected and made freely available should be quality-controlled in a thorough and consistent manner, to ensure that the data meets the ...

    • Quality control procedure for single beam hydrographic data, Version 1. 

      Evans, Emma; McVey, Stuart (Channel Coastal Observatory, National Oceangraphy Centre, Southampton UK, 2019)
      An important driver for the Regional Coastal Monitoring Programmes is that all data collected and made freely available should be quality controlled in a thorough and consistent manner, to ensure that the data meets the ...

    • A Survey of Underwater Acoustic Data Classification Methods Using Deep Learning for Shoreline Surveillance. 

      Domingos, Lucas C. F.; Santos, Paulo E.; Skelton, Phillip S. M.; Brinkworth, Russell S. A.; Sammut, Karl (2022)
      This paper presents a comprehensive overview of current deep-learning methods for automatic object classification of underwater sonar data for shoreline surveillance, concentrating mostly on the classification of vessels ...
