Who We Are

A Global Community of
Ocean Scientists

OceanGliders is a global programme supporting the use of autonomous underwater gliders for sustained ocean observation, coordinating science, data management, and operations across institutions worldwide.

Our Story

OceanGliders History

Gliders are autonomous underwater vehicles that perform saw-tooth trajectories from the surface to depths of 1000 m, along programmable routes. They move up and downward thanks to a buoyancy engine and achieve forward speeds of up to 40 km/day thanks to wings and rudders. They can be operated for months and over thousands of kilometres before they have to be recovered.

Gliders record Essential Oceanic Variables (physical and biogeochemical) at high resolution during dives and transmit these data in near real time to land via satellite when at surface (every few hours). First conceived in the late 1980s, gliders are now incorporated into the operational technology portfolios of many research institutions and agencies, used routinely for both process studies in marine sciences and long-term ocean observation.

The OceanGliders program started in September 2016 to support active coordination and enhancement of worldwide glider activity. OceanGliders contributes to international efforts for Ocean Observation for Climate, Ocean Health and Real Time Services. It brings together marine scientists and engineers deploying gliders all over the world to observe long-term physical, biogeochemical, and biological ocean processes, and to contribute to GOOS through real-time and delayed mode data dissemination.

OceanGliders is distributed across several national and regional observing systems. It shares best practices, requirements, and scientific knowledge needed for glider operations, data collection and analysis, and supports the dissemination of glider data in regional and global databases in real-time and delayed modes.

Open Data

Data Management

OceanGliders promotes open, accessible, and interoperable glider data that maximise scientific and societal value, aligned with FAIR principles and the Essential Ocean Variables (EOVs) framework of GOOS. Data standards, formats, quality control procedures, and best practices are developed through community consensus, coordinated by the Ocean Glider Data Management Team (OGDMT) and maintained at the OceanGliders GitHub.

OG1.0 Data Format

The OceanGliders format (OG1.0, released June 2024) provides a community standard for glider data files, ensuring interoperability across platforms and institutions.

Standard Operating Procedures

Community-reviewed SOPs cover key sensors including oxygen, salinity, nitrate, chlorophyll, depth-average currents, ADCP, and vertical velocities.

Real-Time Data

Data are transmitted via satellite in near real time (every few hours) and disseminated through global databases for both operational and research communities.

MetaData

OceanOPS technical coordination

OceanOPS coordinates with OceanGliders, the operational centre for GOOS observing networks, which maintains the global registry of glider deployments, monitors network status in real time, and ensures glider data are accessible alongside observations from complementary GOOS networks.

Governance
