Researchers, universities, government agencies and environmental organisations use our instruments to better understand marine, coastal and freshwater environments. From oceanography and water quality monitoring to underwater noise studies and long-term environmental observation, our technologies turn complex measurements into practical insight.

CTDs
Our range of CTDs and multi‑parameter loggers are essential tools for profiling aquatic environments. They record temperature and depth along with conductivity to derive salinity, density and sound velocity, and many models combine sensors for dissolved gases, pH and optical signals such as chlorophyll, fDOM and turbidity. Compact and low‑power designs allow these instruments to be fitted to gliders, AUVs and moorings.
Underwater Gliders
We supply a range of Gliders with significant depth ratings, these buoyancy driven vehicles are designed for long-range ocean surveys. By silently modifying its buoyancy and using a small propeller for heading, the glider moves up and down through the water column and maintains an efficient horizontal trajectory. It can carry multiple sensors to measure physical, chemical, biological and acoustic parameters and sends data ashore via satellite. Easy to deploy, Gliders offer long endurance and low maintenance operations, making them ideal for coastal work and deep water research.
Drifters
Drifters are buoys that float with the currents and send precise location and surface data via satellite. Designed to work in surface ocean currents for scientific research, track spills and pollutants and support rescue and recovery missions.
Models such as the MetOcean iSPHERE and Stokes drifter provide real‑time GPS positions, sea‑surface temperature readings and two‑way communication, allowing users to customise reporting intervals and receive data whenever needed. These compact drifters help scientists study shallow‑water currents, responders predict where oil and debris will travel and rescue teams mark and follow search areas.
FAQ
What is an underwater glider and what makes it different from other vehicles?
Underwater gliders are autonomous vehicles that change buoyancy to glide up and down through the water column, which allows them to travel long distances quietly and efficiently. As an example, the Alseamar SeaExplorer glider adjusts its buoyancy while a small propeller helps steer it, keeping a horizontal trajectory. It can be equipped with sensors to measure physical, chemical, biological and acoustic parameters whilst transmitting data via satellite.
How do drifters support search pollution monitoring?
Drifters like the Stokes and iSLDMB can be deployed quickly from boats or aircraft, and their GPS and sea‑surface temperature sensors provide accurate real‑time data via Iridium communications. For pollution monitoring, their precise position data help forecast where oil, flotsam or other pollutants will move.
Why are CTD sensors ideal for oceanographic research?
CTD’s which stands for temperature and depth allows researchers to derive salinity, density and sound velocity for water masses. Multi‑parameter loggers build on this foundation by adding sensors for dissolved gases, pH, chlorophyll, turbidity and other optical parameters. These compact, low‑power instruments can be deployed on gliders, AUVs or moorings and provide accurate, high‑resolution data for oceanography, water quality monitoring and other marine science.
