Open Meetings

Research Symposia and Workshops

One of the goals of the DECAF project was to further research on passive acoustics methods to estimate cetacean density, by organizing open research symposia and workshops.  These meetings also served to disseminate latest research ideas to those interested in using them to monitor cetaceans.

We welcome your suggestions for further training or research events we could deliver or participate in.  Feel free to contact us with suggestions.

Tutorial and research symposium at 6th International Workshop on Detection, Classification, Localization (DCL) and Density Estimation (DE) of Marine Mammals

11th June 2013, St Andrews. Scotland.

Preceding the 6th International DCL/DE workshop (12th-15th June), we gave a half-day tutorial aimed at introducing the theory and methods of density estimation of cetaceans from passive acoustics.  Workshop material was a shortened version of the material presented at the IDEA workshop below.

IDEA: Introduction to Density Estimation using passive Acoustic data.
Workshop given at the 27th Conference of the European Cetacean Society

6th April 2013, Setubal, Portugal

As part of the 27th ECS conference, we will present a one-day tutorial aimed at introducing the theory and methods of density estimation of cetaceans from passive acoustics.  A copy of the lecture slides is given below — we’d be happy to hear any feedback (good or bad!) on this material as we’d like to give more, similar workshops in the future.

Tutorial and research symposium at 5th International Workshop on Detection, Classification, Localization (DCL) and Density Estimation (DE) of Marine Mammals

21st-25th August 2011, Mount Hood, Portland, Oregon, U.S.A.

As part of the 5th International DCL/DE workshop, we gave a one-day tutorial aimed at introducing the theory and methods of density estimation of cetaceans from passive acoustics.  Around 20 people attended.

1st International Workshop on Density Estimation of Marine Mammals Using Passive Acoustics

13th September 2009, Pavia, Italy.
Hosted by the Centro Interdisciplinare di Bioacustica e Ricerche Ambientali.

This one-day workshop was linked to the 4th International Workshop on Detection, Classification and Localization (DCL) of Marine Mammals Using Passive Acoustics, and was attended by around 70 people.  The day started with a tutorial review, followed by 12 research presentations and ended with a useful discussion of the current state of knowledge and future directions.  The meeting agenda is available below, together with a copy of the review talk.  Our thanks to Gianni Pavan of CIBRA for hosting the workshop.

One-day symposium on Estimating Cetacean Density from Passive Acoustics

16th July 2009, San Diego, California, USA. 
Hosted by the Scripps Institution of Oceanography (SIO).

This event was attended by around 40 people.  9 talks were presented, copies of which are available below (as Adobe pdf files).  Our thanks to John Hildebrand of SIO for hosting the event.
