Marine mammal monitoring is a difficult task. Systems are required to perform well over a localized area when used for real-time environmental mitigation. Systems can also be tasked to conduct marine mammal surveys over a much wider area to derive more general information, such as density estimates by region and species. The algorithms used to automate processing and analyses are relatively new and require more study to understand their performance, and to invent better methods. The systems themselves also need to be studied to generate better solutions, while understanding current performance. This report documents the contracting effort related to a significant marine mammal data analysis effort that considers four system types (Slocum Gliders, Delphinus Array, sonobuoys, and AUTEC range sensors) used on the MMOS ‘09 /CFAV Quest Cruise Q320 sea trial, with the analysis results captured in a separate report. During the contract, analysts examined almost three days of recorded data using both manual analysis and automated detection processing. The automated detections were then compared to the manual results to derive high-level valid detection and false alarm statistics. Manual and automated detection results from each system were compared to high-level AUTEC detection results in an attempt to compare performance, though the lack of raw data from AUTEC limited the quality of the analysis. The level of self-noise on the systems was examined, with a more detailed comparative
