AML Oceanographic is a leading designer and manufacturer of sensors and instrumentation that serve a wide range of underwater and marine applications including hydrography, scientific research, offshore construction, and water quality monitoring. The company is a pioneer in the development of field-swappable sensors, and is also the inventor of the time-of-flight sound velocity sensors that are now used widely in multibeam sonar systems.

With 50 years of experience, AML supplies customers on all seven continents, with a wide-ranging after-sales support network and calibration centers around the world.

Hydrographic & Oceanographic Sensors

The X2Change series offers the industry’s most extensive portfolio of hydrographic and oceanographic sensors. Compatible with AML Oceanographic’s AML-1, AML-3, and AML-6 instruments, as well as Endura Loggers, these robust field-swappable units can also be integrated into OEM and third-party equipment.

All sensors contain their own embedded calibration, enabling them to be exchanged between different systems without affecting accuracy, and can be easily and directly installed onto the instrument end cap.

Single- & Multi-Sensor Instrumentation

Single-Sensor Data Probe

The AML-1 is a modular and versatile underwater data probe that can be fitted with any single sensor from the X2Change family. It is ideal for beam steering in multibeam sonar applications, as well as data collection on buoys and underwater observatories.

Offering real-time data streaming via serial RS-232 or RS-485, it features a robust titanium housing that allows it to operate at depths of down to 6000 meters.

Multi-Sensor Oceanographic Profiler

The AML-3 is a highly versatile oceanographic instrument for water column profiling and monitoring applications, and can be fitted with any three sensors from the X2Change family. It is ideal for underwater vehicles as well as fixed-site observatories. As some X2Change sensors are dual-parameter, this allows the AML-3 to directly measure up to four distinct parameters simultaneously.

The instrument is available in three variants – an entry-level system for real-time data streaming without battery or memory, a version with a Lithium-ion battery and onboard memory, and a premium option that offers both real-time streaming and data logging capabilities.

Multi-Parameter Underwater Sonde

The AML-6 is a multi-parameter sonde that is designed to combine CTD data with other oceanographic parameters such as Dissolved Oxygen, pH, ORP, or Fluorometric data. It can be equipped with up to six sensors from the X2Change family, and can also be fitted with UV biofouling control to ensure enhanced data quality and reduced maintenance requirements.

Endura Loggers

AML’s Endura Loggers are connector-free and wirelessly charged instruments that have been designed specifically for demanding unmanned and autonomous vessel applications. With effectively unlimited endurance and enhanced mechanical reliability, these advanced profilers unlock new capabilities for hydrographic and oceanographic surveyors.

Endura Loggers are available with three or six ports for field-swappable X2Change sensors.

UV Biofouling Control

AML Oceanographic’s advanced biofouling solutions are designed to protect underwater sensors and marine equipment, utilizing ultraviolet lamps to prolong the time between required maintenance without utilizing TBT or other harmful chemicals.

Street Lamp UV is a highly efficient solution designed to be directly integrated with AML instrumentation, drawing just 1W of power at 12V. With a maximum depth rating of 500 m, it ensures optimal biofouling control within a range of approximately 30 cm.

The Cabled UV system is intended for applications where all AML instrumentation sensor ports are occupied. It is available in both vertical and horizontal configurations, with minimal power draw and excellent anti-biofouling performance.

Moving Vessel Profilers

AML’s MVP (Moving Vessel Profiler) systems are designed to continuously and autonomously collect high-resolution water column data in real time, offering unmatched survey efficiency and the ability to capture a wide array of environmental and scientific parameters. With options for USVs, smaller survey vessels, and larger oceanographic platforms, the MVP product portfolio offers the state of the art in underway profiling systems.
