Quick answer: Arctic and polar ocean monitoring with autonomous platforms means deploying wind and solar-powered surface vehicles in high-latitude environments where research vessels face severe weather and access limitations. These platforms can operate through winter conditions, in waves exceeding 14 metres and winds above 30 m/s, providing continuous data from regions and seasons that are routinely absent from oceanographic records.

Why polar ocean monitoring is difficult
Research vessels face significant constraints in polar and sub-polar environments. Winter conditions, sea ice, storm frequency, and cost all limit the time vessels can spend collecting data at high latitudes. The result is that winter Arctic and Antarctic conditions are systematically underrepresented in long-term ocean datasets. Autonomous platforms designed for extreme environments can operate precisely when and where crewed vessels cannot.
Verified Arctic and polar deployments
In the GLIDER project, a Sailbuoy was deployed alongside two other autonomous platforms along the Lofoten-Vesterålen shelf-slope system in Arctic Norway. Equipped with an echo sounder for zooplankton density and distribution measurement at shallow depths (2 to 10 m), the deployment revealed plankton distribution patterns not previously observed through ship-based surveys. Results were published in a peer-reviewed paper in Sensors (2021): "Autonomous Surface and Underwater Vehicles as Effective Ecosystem Monitoring and Research Platforms in the Arctic." The deployment demonstrated continuous monitoring in extreme conditions including waves of 15 metres and winds of 30 m/s.
In 2024, Jonas Hentati-Sundberg of the Swedish University of Agricultural Sciences deployed a Sailbuoy for the first acoustic survey of the Hudson Bay Arctic marine ecosystem. The deployment extended an established research collaboration that had accumulated over 500 operational days in the Baltic Sea between 2019 and 2023.
The British Antarctic Survey deployed Sailbuoys from the Government of South Georgia patrol vessel MV Pharos SG for Antarctic krill monitoring from South Georgia. Platforms were equipped with 200 kHz and 120 kHz echo sounders alongside oceanographic sensors including oxygen, conductivity, salinity, temperature, and fluorometer. BAS is using the deployments as a net-zero case study, comparing carbon, financial, and time costs of autonomous data collection against traditional research vessel operations.
What polar autonomous monitoring makes possible
Continuous monitoring in extreme conditions provides access to winter Arctic data when research vessels cannot operate, enables large spatiotemporal scale monitoring, and uses a low-impact survey methodology suitable for sensitive ecosystems. The platform can be configured for physical oceanography, acoustic monitoring, and biogeochemical measurements depending on the research requirement.
FAQ
How does the platform handle winter Arctic conditions? The platform has operated in 30 m/s winds and waves exceeding 14 metres. Arctic deployments have been conducted including during winter. The wind-driven propulsion system means the platform is not limited by battery capacity for navigation, enabling it to remain on station through extended periods of severe weather.
Can it be deployed from existing polar research infrastructure? Yes. The platform can be deployed from vessels of 6 metres or larger, including patrol vessels and smaller research support craft. It ships in a standard transport case suitable for air freight.
What data can be collected in polar environments? Standard sensor configurations cover acoustic monitoring (echo sounders in multiple frequencies), physical oceanography (CTD), dissolved oxygen (Aanderaa Optode), and meteorological measurements. Passive acoustic monitoring via hydrophone is also available.
