This dataset used multiple hydrophones at PMRF, Kauai, Hawaii, to localize minke whale boing vocalizations manually. This was a precursor to development of automated detection algorithms and automated association processes. This data set provided a quasi ground truth for development and performance assessment of the minke boing detector developed in the DECAF project. The ultimate purpose of the project was to estimate the density of the boing vocalizations in order to gain more understanding of the minke whale presence in Hawaiian waters. In order to estimate density of whales, the average boing rate of a minke whale is required. Hydrophone locations are only approximate. This data represents call detections - individual animals may make multiple calls. more
This data set consists of manually detected boings from multiple hydrophones off the northwest of Kauai, Hawaii. Boings were detected utilizing visual displays of signal spectrograms and time series along with aural monitoring. The boings have a distinctive sound character with major energy in the 1.4kHz area. These manual detections provided information necessary in order to assess performance of the automated boing detector and to help understand how to better automatically detect, associate and localize boing sound source locations. Manual validation of automatic processes is much more efficient (in time and dollars) than the total manual effort such as performed in this data set and the manual localization data set # 675. This analysis was conducted by James Yosco (Science Applications International Corporation. Times are in GMT. Hydrophone locations are only approximate. The detailed results of the analysis are available at the DECAF web site shown in the supplemental information section. This dataset is part of a larger project examining Balaenoptera acutorostrata (minke whale) vocalizations at the Pacific Missile Range Facility (PMRF). Related datasets include:
