The hardware is based on the Zynq system-on-a-chip (SoC), which features a large field-programmable gate array (FPGA) and two ARM processing cores. The FPGA is used to implement real-time filtering for the analog-to-digital converters and a real-time detector for odontocete clicks. JASCO’s PAMlab JAVA software has been adapted to run in the ARM processors. This allows for the detector algorithms to be tested and proven using recorded data sets, and the deployment of algorithms in the real-time hardware using the same proven software baseline. The advantages of this approach for rapidly adapting generic hardware to diverse monitoring projects will be highlighted.JASCO Applied Sciences has developed a novel passive acoustic monitoring system, the OceanObserverTM, that has been fielded in undersea and surface AUVs as well as on buoys and sub-sea observatories.

JASCO’s “Observer/AMAR G4” is a family of components configured to deliver a wide spectrum of functionality to users and researchers. The capabilities of the Observer/AMAR family of components are described via a walkthrough of recent Observer/AMAR glider deployments and trials, with a focus on functionality, collected data, and lessons learned. The trials include an Observer-based Slocum glider (Teledyne Webb Research) deployed in the Gulf of St. Lawrence, Atlantic Canada, in search of endangered North Atlantic right whales. Installations and test deployments in Seaglider (Kongsberg) on the west coast of Norway and in SEAEXPLORER (ALSEAMAR) on the south coast of France are also described. The development and the beneficial capabilities of these novel systems are described, as well as the results from these trial deployments.

It can be integrated with small hydrophone arrays and non-acoustic oceanographic sensors. To date, AMARs have typically been used autonomously and deployed for a few months to a year on oceanographic moorings; however, AMARs are also capable of real-time data streaming when connected to a data telemetry system. This paper describes the capabilities and functionality of the AMAR through the example of its integration within Ocean Networks Canada's VENUS Ocean Observatory deployed off the coast of British Columbia, Canada. The recent deployment of two AMAR-based hydrophone arrays and associated non-acoustic and oceanographic sensors within the VENUS system is presented in detail. The planned research and development within the AMARs on VENUS program, as well as preliminary results on the real-time automatic detection, classification, localization, and tracking of marine mammals, are presented. The two AMARs deployed on the VENUS Ocean Observatory demonstrate that, unlike traditional underwater acoustic recorders, the AMAR can act as a hub for mini ocean observatories, capturing and transmitting both acoustic and non-acoustic sensor data in realtime. It is demonstrated that the AMAR is an effective technology that can be used in near-shore, small-scale, low-cost ocean observatories.
