OceanObserver Glider

OceanObserver on the Slocum Autonomous Underwater Glider

Intelligent acoustic monitoring on one of the world’s most utilized underwater gliders.

Marine mammal monitoring without the cost of vessel or aerial surveys:

  • 24/7 monitoring in any sea state

  • Long-term monitoring over wide areas

  • Deploy from any size vessel

  • Customized detections and processing

  • Detections sent by satellite in near real-time

  • Data recorded on 6 TB of SD memory

Near real-time detections

Installed in the Slocum’s science bay, the OceanObserver records the data from one or more hydrophones and processes it to detect marine mammal calls or events of interest.

Surfacing at specified intervals, the glider sends the detections to shore for analysis and decision-making.

Customized detectors & communications

Onboard processing is done with PAMlab INT, the integrated version of JASCO’s PAMlab software suite. Our experienced bioacousticians tailor the detectors by species and call type.

The processed events are ranked so important events, like species at risk, are sent first, making best use of the communication window. Event information is distributed by email. Concurrent detections are associated to provide contextual information for onshore analysts.

Hydrophone data, and even spectrogram images, are too big to send by satellite. So simplified frequency contours are sent instead. Superior to pitch tracks, the contours give a rich picture of the data so analysts can identify species more easily and accurately.
