What We Do


Acoustic Scintillation Flow Meter Used for Flow Measurements at the Beaucaire Bulb Turbine Hydropower Plant, France

ASL AQFlow is pleased to announce that our Acoustic Scintillation Flow Meter (ASFM) is being used by the Compagnie Nationale du Rhône (CNR) to conduct flow measurements at the Beaucaire Hydropower Plant on the Rhône River in France as part of an electrical production optimization program. This site generates approximately 210 MW of hydroelectricity from six bulb turbines. Figure 1 shows the instrumented frame that is lowered into the hydroelectric plant intake to the turbine and is equipped with an ASFM array that measures flow across 30 paths. Prior to this installation, the ASFM was successfully deployed at the Châteauneuf-du-Rhône, Montélimar-Henri-Poincaré- hydroelectric plant, another of CNR’s facilities on the Rhône River. The quality of the data collected at this site was considered very high and results were repeatable with an average uncertainty of roughly 0.4%.

David Fissel CMOS Fellow

ASL’s David Fissel Named a Fellow of the Canadian Meteorological and 
Oceanographic Society (CMOS)

The Vancouver Island CMOS Centre and ASL co-hosted a reception and award presentation ceremony at the University of Victoria, University Club, Thursday October 6th to honour those that have contributed significant scientific achievements. At this ceremony, ASL’s David Fissel was named a Fellow of the Canadian Meteorological and Oceanographic Society (CMOS).

David Fissel was educated at the University of British Columbia, earning a B.Sc. in Honours Physics in 1971 and an M.Sc. in Physical Oceanography in 1975. His graduate research, carried out under Professor Steve Pond, was followed, in 1975, by working as a Physical Oceanographer at the Government of Canada’s Institute of Ocean Sciences. His initial studies focused on currents in the Strait of Juan de Fuca and circulation patterns in the eastern half of the Northwest Passage.

Amanda Dash

ASL Hires Amanda Dash for the Position of Machine Learning and Computer Vision Specialist

ASL is excited to announce Amanda Dash's appointment to the Machine Learning and Computer Vision Specialist position as a part of our team. She contributes over five years of experience in research in Machine and Deep Learning and over a decade of software engineering and development. Amanda will be bringing her expertise to various projects at ASL.

Before her appointment at ASL, Amanda completed a Computer Engineering Technologist diploma at Saskatchewan Polytechnique and a Bachelor of Software Engineering at the University of Victoria. She has published research on bird population estimates, video summarization, classification and segmentation of images during her studies. Additionally, her studies have taken her to Beijing, China and Iqaluit, Nunavut, on various internships.

ASL Announces Dr. Philip Matthews as the 2022 Acoustic Zooplankton Fish Profiler Award Contest Winner

ASL Environmental Sciences is pleased to announce Dr. Philip Matthews as the winner of the sixth annual Acoustic Zooplankton Fish Profiler (AZFP) early career scientist award contest. Dr. Matthews is an Associate Professor in the Department of Zoology at the University of British Columbia (UBC) and runs the Comparative Respiratory Physiology and Biomechanics laboratory.

Dr. Matthews will be using a multi-frequency AZFP to understand the physiology and ecology of the deepest diving insect in the world—the Chaoborus edulis of Lake Malawi in southeastern Africa. He will be leading a team of two UBC graduate students, a fisheries research officer from Malawi and a UBC associate professor.
