What We Do
AML Oceanographic Ltd. is a Canadian marine technology company specializing in the design and manufacture of precision oceanographic instrumentation used to observe, quantify, and understand the physical properties of the ocean. Founded in 1974 and headquartered in Sidney, British Columbia, AML has more than five decades of experience supporting ocean science, hydrography, and applied marine research in some of the world’s most challenging environments.
At its core, AML’s work is grounded in ocean measurement science—the accurate, repeatable, and reliable observation of water properties such as conductivity, temperature, pressure, sound velocity, and optical parameters. These measurements underpin a wide range of scientific and operational activities, from climate and circulation studies to acoustic seabed mapping and ecosystem monitoring.
Our instruments are designed with an emphasis on data integrity, traceable calibration, and long-term stability, recognizing that small measurement uncertainties can propagate into significant errors in downstream analyses such as sound-speed correction for multibeam echosounders or density calculations for water-column studies.
AML has contributed several notable technological advances to the field of ocean instrumentation. The company pioneered time-of-flight sound velocity measurement, a method that provides highly accurate and responsive sound-speed data critical for underwater acoustics and sonar performance. This innovation is now widely adopted in hydrographic and acoustic research communities.
A defining characteristic of AML’s instrumentation is our modular, field-swappable sensor architecture. Technologies such as Xchange™ sensors allow calibrated sensing elements to be exchanged without returning the instrument to a laboratory or factory. From a scientific perspective, this reduces instrument downtime, supports rapid redeployment, and enables more flexible experimental design—particularly valuable for remote field campaigns or time-sensitive surveys.
We've also addressed one of the persistent challenges in ocean observation: biofouling. The introduction of UV-based antifouling systems helps maintain optical and conductivity sensor performance during long-term deployments, improving data continuity and reducing post-processing uncertainty.
AML instruments are used extensively in physical oceanography, hydrography, limnology, and environmental monitoring. They support both discrete profiling and continuous underway measurements, enabling researchers to resolve spatial and temporal variability in the water column. Typical applications include:
- Water-column characterization for acoustic propagation studies
- Sound-speed profiling for multibeam and sidescan sonar correction
- Long-term monitoring of coastal and estuarine systems
- Process studies related to mixing, stratification, and circulation
- Support for climate, habitat, and sediment transport research
The acquisition of the Moving Vessel Profiler (MVP) expanded our capability to support high-resolution, underway ocean profiling, allowing researchers to collect frequent vertical profiles without interrupting vessel operations—an important advancement for modern survey efficiency and data density.
