What We Do

Midge Fly hatch

Acoustic Zooplankton Fish Profiler (AZFP) Used to Monitor Diving Insects in Lake Malawi, East Africa

Dr. Philip Matthews, Associate Professor in the Department of Zoology at the University of British Columbia and winner of the 2023 annual Acoustic Zooplankton Fish Profiler (AZFP) award, and Dr Maxon Ngochera, Chief Fisheries Research Officer, Malawi, have now completed their field work. This work centered on examining the unmatched diel migration of the aquatic larvae of the Chaoborus edulis, a midge fly that is abundant in Lake Malawi, East Africa.  The goal of this research was to use ASL’s multifrequency AZFP to better understand the physiology and ecology of Chaoborus edulis larvae, the deepest free-diving insects in the world. 

ASL Invited to Teach Hydroacoustics at
Bamfield Marine Sciences Centre

Every year Bamfield Marine Sciences Centre (BMSC), located on the west side of Vancouver Island, British Columbia, offers world-class, university-level courses on a variety of topics including biological oceanography. This summer this course was taught by Dr. Jennifer Putland and Dr. Louis St. Laurent of the University of Washington. As part of the course, ASL staff member Julek Chawarski was invited to teach students about hydroacoustics and how to analyze complex oceanographic data. Prior to this course an ASL Acoustic Zooplankton Fish Profiler (AZFP) was deployed to collect data on krill and fish in the Barkley Sound area 


ASL is Now a Region Representative for ANB Sensors

ASL is pleased to announce that we have entered into a product sales agreement with ANB Sensors of Cambridge United Kingdom. ANB Sensors have developed a next generation calibration-free, solid-state, multi-parameter pH, conductivity and temperature sensor. Unlike other pH sensors that require frequent re-calibration, the ANB sensors uses a patented technology that automatically carries out in-situ calibrations throughout the deployment.  These sensors can be deployed individually or integrated into underwater vehicles, sondes or monitoring platforms using the optional dedicated integration kit. There are four available options for operating at 5 m, 50 m, 300 m or 1250 m depths 


ASL Represents WERA’s Ocean Radar, A System Suited for Surveillance Applications of Off-shore Infrastructure

The topic of surveillance of civil off-shore infrastructure is increasingly becoming a significant issue globally. In response to this, WERA has provided an upgrade to its High Frequency ocean radar system to monitor ship activities far behind the horizon. Several “WERA” ocean radar systems are located on the European coastline as well as the East and West Coasts of North America. The systems located at the German Bight, the Dutch North Sea coast, and the French and Italian Coasts are particularly well suited for this technical application of ship detection.
The WERA ocean radar, represented in Canada by ASL Environmental Sciences, is classified as a “dual-use” system because it is suited for oceanographic applications as well as over-the-horizon ship detection and tracking.
