DCLDE 2015 Datasets

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-06-05T00:00:00.000+00:00
DCLDE Workshops are intended for exchanging information that advances our understanding of acoustic methods to detect, classify, locate, track, count, and monitor marine mammals in their natural environment. The goal is to encourage interdisciplinary approaches to solve real-world problems related to the study of marine mammals and the effects of human activities. The DCLDE 2015 dataset consists of data from multiple deployments of high-frequency acoustic recording packages deployed in the Southern California Bight. Separate sets of development data are provided for mysticetes and odontocetes. The mysticete data have been decimated to 1 and 1.6 kHz bandwidth and the odontocete data bandwidth consists of data with 100 and 160 kHz of bandwidth. Data were selected to cover all four seasons and from multiple locations. High-frequency datasets consist of annotated data from multiple odontocete species. Included is Baird’s beaked whale (Berardius bairdii), Cuvier’s beaked whale (Ziphius cavirostris), Sperm whale (Physeter macrorhynchus), Pacific white-sided dolphin (Lagenorhynchus obliquidens), Risso’s dolphin (Grampus griseus), unspecified porpoise (Phocoenidae), and odontocete other than those described above (Odontoceti). The goal for this dataset is to identify acoustic encounters of a species during times when animals were echolocating. Low-frequency datasets consist of annotated data for specific calls from two mysticete species, blue whale (Balaenoptera musculus) D calls and fin whale (Balaenoptera physalus) 40 Hz calls. The goal for this dataset is to identify specific blue whale D and fin whale 40 Hz calls.
