DCL workshop 2011 - Welcome!

The 5th International Workshop on Detection, Classification, Localization, and Density Estimation of Marine Mammals using Passive Acoustics will be held 22-25 August 2011 at Timberline Lodge, Mount Hood, near Portland, Oregon, USA. Immediately preceding the workshop, on Aug. 21, will be two tutorials presented in parallel: Introduction to Detection, Classification, and Localization (DCL) and Introduction to Density Estimation (DE).

The biennial International Workshops on Detection, Classification, Localization, and Density Estimation of Marine Mammals using Passive Acoustics (the DCLDE Workshop) are intended for exchanging information that advances 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 on their behavior.

The 2003 (Halifax, Canada), 2005 (Monaco), and 2007 (Boston, USA) DCLDE workshops were dedicated to solving problems related to individual species. The 2009 (Pavia, Italy) workshop focused on the analysis of real-world complex acoustic scenes and the use of context for identifying acoustic components of interest. The focus of the 2011 workshop is classification of odontocete sounds, including both whistles and clicks. Most odontocetes, excepting sperm whales and some beaked whales, produce whistle vocalizations that are thought to be used for communication. Although there have been some efforts at classifying whistle vocalizations over the last 15 years or so, to date there has not been a strong focus by the DCL community on classifying whistles, and none on classifying both whistles and clicks together.

Researchers are invited to present their scientific work, to detail the advantages and drawbacks of the methods they use, and to show their recent results. Both oral and poster presentations are welcomed. Participants are encouraged to test their methods using the standard dataset of underwater recordings provided online at MobySound.org under 5th workshop and discuss the results; use of the standardized data set will facilitate direct evaluation and comparison of different approaches and solutions.

Presentations from different research and academic fields are welcome. Specialists in biology, physiology, acoustics, oceanography, signal processing, mathematics, electronics, and computer science are all invited to bring their experience to the workshop.
