ASL Environmental Sciences products

An autonomous scientific echosounder with unmatched combination of multiple frequency operation, low power and long endurance that fits your budget.

The AZFP-nano is a compact, lightweight, single frequency scientific echosounder. A miniaturized version of the AZFP, it is easily portable and well suited for applications in challenging environments where size and weight are important considerations.

The Acoustic Zooplankton Fish Profiler-ice (AZFP-ice) combines the AZFP`s abilities to monitor the presence and abundance of zooplankton, fish, suspended sediments and bubbles within the water column as well as the Ice Profiling Sonar`s (IPS) ability to measure ice draft. A powerful calibrated tool for scientific research and environmental monitoring in oceans, lakes and rivers.

An upward-looking sonar device, mounted on the ocean floor to accurately measure ice draft.

An upward-looking sonar device, mounted on the lake/river/ocean floor to accurately measure ice draft in shallow water environments.

The ASL Mini Logger gathers oceanographic sensor data and can be customized to suit your needs.  The data can be stored locally on the logger or transmitted to shore in real-time. A shore station can then relay the data using various modem technologies to the cloud for access from the Internet. The shore station is usually configured to provide power to the logger. ASL supplies several options for shore stations including powering, modem antennas and other shore station infrastructure.

A highly accurate upward-looking instrument for measuring waves at continental shelf depths. The Wave Profiler allows the user to measure non-directional wave parameters continuously for long periods of time with high temporal and spatial resolution in deeper water from the safety of an underwater mooring. The instrument is particularly useful for clients who need to measure long-period waves (such as rogue waves or infra-gravity waves), waves in wash and in wakes, and non-linear waves.

ASL provides many solutions for your mooring needs. Whether you’re deploying a single instrument or a whole suite, we have a host of designs to suit your requirements.
