Wave Gliders Collect Live Ocean Data from Hawaii’s Kilauea Volcano Lava Flow

June 25, 2018

Liquid Robotics announces the deployment of two Wave Gliders, autonomous ocean robots, to capture live ocean data close to where lava is flowing into the ocean from Hawaii’s Kilauea Volcano. By using this unmanned technology, scientists have the rare opportunity to study the effects of the lava entering the ocean, the plume it creates and […]

Top Oceanographers Select Wave Gliders to Study Arctic and Southern Oceans

June 5, 2018

Top oceanographers from Scripps Institution of Oceanography (Scripps) and the Applied Physics Laboratory of the University of Washington (APL-UW) have selected Wave Gliders, the most experienced, long duration ocean robots, as their sensor platform to conduct advanced scientific research in the most inhospitable and remote regions of the Arctic and Southern Oceans. Using Liquid Robotics […]

Japan Coast Guard Expands Wave Glider Fleet to Advance Ocean Observation

March 7, 2018

The Japan Coast Guard (JCG) announced the expansion of their unmanned ocean observation fleet of Wave Gliders to the 9th Regional District, headquartered in Niigata, Japan. This growth is part of JCG’s multi-year, ocean monitoring program to provide enhanced, real-time situational awareness of ocean currents, wave activity, and weather along Japan’s coastlines. Prior to this […]

Sea Surface Height Measurement Using a GNSS Wave Glider

Penna, Nigel T., Miguel A. Morales Maqueda, Ian Martin, Jing Guo, and Peter R. Foden

To overcome spatial and temporal limitations of sea surface height (SSH) instruments such as tide gauges, satellite altimetry and Global Navigation Satellite Systems (GNSS) buoys, we investigate the use of an unmanned, self‐propelled Wave Glider surface vehicle equipped with a geodetic GNSS receiver. Centimetric precision instantaneous SSH measurement is […]

Seafloor geodesy: Acoustic direct-path ranging for monitoring seafloor deformation

Petersen, Florian, Heidrun Kopp, Dietrich Lange, Katrin Hannemann, and Morelia Urlaub

Abstract: The seafloor stores crucial information on sub-seafloor processes, including stress, elastic strain, and earthquakes. This information may be extracted through the nascent scientific field of seafloor geodesy. The GeoSEA (Geodetic Earthquake Observatory on the SEAfloor) array uses acoustic signals for direct-path ranging and relative positioning at mm-scale resolution […]

Evaluation of satellite and reanalysis wind products with in situ Wave Glider wind observations in the Southern Ocean

Schmidt, Kevin M., Sebastiaan Swart, Chris Reason, and Sarah Nicholson

Abstract: Surface ocean wind datasets are required to be of high spatial and temporal resolution and high precision to accurately force or be assimilated into coupled atmosphere-ocean numerical models and understand ocean-atmospheric processes. In situ observed sea surface winds from the Southern Ocean are scarce and consequently the validity […]
