DCLDE - Passive acoustic monitoring of marine mammals


The Detection, Classification, Localisation and Density Estimation (DCLDE) of marine mammals workshop is held on a biannual basis. During this workshop the participants share their recent insights into algorithms and technology for automated acoustic monitoring of marine mammals. The workshop is open to anyone with an interest in the topic (such as staff/students from different universities, research organizations, research/consultancy companies, government-affiliated research groups, and industry). A data set is typically provided by the workshop organization so that the community can work on this dataset and results can be compared. In addition, different sessions on novel techniques for passive acoustic monitoring and estimating marine mammal densities will be organized.

Workshop dataset - Revisiting North Atlantic Right Whales for the third time

A dataset has been made available for the DCLDE2024 workshop which is related to real-time localisation of North Atlantic right whales using sonobuoy networks. The use of distributed fields of sensor systems for real-time acoustic monitoring and tracking of marine mammals is becoming increasingly used in the field. The main benefit of these datasets are that they provide a challenging dataset for researchers in this field of marine mammal research to develop and compare novel techniques for this purpose. These novel techniques could be applied to the real-time detection, classification, and localisation of the highly endangered North Atlantic right whales. Different nations have implemented regulations and are developing tools to protect this species. This research will support governments and industries to mitigate negative effects on North Atlantic right whales, i.e. by helping to avoid ship collision or underwater noise pollution, or identification of biologically important areas.

The workshop will be held from the 3rd - 7th of June 2024 in Rotterdam, the Netherlands. Rotterdam is the largest European port, a popular cultural hub, and is well known for its modern architecture. We plan to host a hybrid meeting allowing for more people to participate, as well as making us flexible in the event of potential travel restriction due to Corona.

At this moment, we are seeking contributions for covering the workshop costs. For this we are approaching multiple organizations to sponsor the full cost of the workshop and supporting of young starting scientists to attend the workshop. If you are interested in supporting this workshop, please feel free to contact the organizers here.


Rotterdam is a major port city in the Dutch province of South Holland. The Maritime Museum's vintage ships and exhibits trace the city's seafaring history.

Data Sets

This dataset is kindly made available to the DCLDE community by a large Canadian research consortium. During the workshop we will present and compare the outcome of different approaches to localize North Atlantic Right Whales using this dataset.
