Multiple sensor case studies

  • Case Study 1b: Minke whale data
    • Description: This archive contains data on minke whale (Balaenoptera acutorostrata) calls (boings) recorded at the Pacific Missile Range Facility in 2006 and 2007.  Data from several analyses are provided here: localisation information of a sample of boings, time and frequency information of boings associated across multiple hydrophones (for both a preliminary analysis and a main analysis) and the number of boings detected in the main analysis using an automatic detector.  Approximate hydrophone locations at PMRF are also provided.

  • Case Study 2: Sperm whale data
    • Description: This archive contains data on sperm whales (Physeter macrocephalus) recorded at the Atlantic Undersea Test and Evaluation Center (AUTEC) in the Tongue of the Ocean, Bahamas in August/September 2007.  Data are provided showing when sperm whales were detected on the range during the time period, details about the availability of the acoustic data used in the analysis and finally, the number and size of sperm whale groups localised.

  • Case Study 3: Beaked whale data
    • Description: This archive contains data on ecolocation clicks of Blainville’s beaked whale (Mesoplodon densirostris) recorded at AUTEC during a 6-day period in spring 2005.  The data were used in estimatingM. densirostris density as documented in the paper Marques et al. (2009).  There are data files containing click counts per minute per hydrophone, files containing numbers of false positive detections from a manual analysis, and files giving information about georeferenced tracks of tagged whales and associated vocalization timings.

Single sensor case studies

  • Case Study 4a: Beaked whale data
    • Description: This case study estimated M. densirostris density at AUTEC using a single hydrophone.  The method was comprised of several separate stages and analyses.  This archive provides the results from an analysis that characterised the performance of the automatic detector used to detect beaked whale clicks.
