A single porpoise-like event was attributed to a sighting of <i>Kogia simus</i>. The Porpoise detector was developed by Douglas Gillespie and Olly Chapple for the International Fund Welfare (IFAW). It uses analog envelope tracing and software detectors; two narrow bandpass filters centered around 50 and 72 kHz and one broadband filter (100 kHz - 150 kHz). These are used to detect the broadband click ultrasonic vocalizations of dolphins, and the narrow band clicks produced by the harbor porpoise (<i>Phoceona phocena</i>), Vaquita (<i>Phocena sinus</i>) and <i>Kogia spp.</i> The detector was extensively trialled in the Baltic (Gillespie et al. 2005; OBIS-SEAMAP dataset: <a href=http://seamap.env.duke.edu/datasets/detail/343>Baltic Porpoise Acoustic Surveys 01-02</a>) and upper Gulf of California.<br><br> References:<br> Gillespie, D., P.
