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 […]

Optimal path shape for range-only underwater target localization using a Wave Glider

Masmitja, Ivan, Spartacus Gomariz, Joaquin Del-Rio, Brian Kieft, Tom O’Reilly, Pierre-Jean Bouvet, and Jacopo Aguzzi

Underwater localization using acoustic signals is one of the main components in a navigation system for an autonomous underwater vehicle (AUV) as a more accurate alternative to dead-reckoning techniques. Although different methods based on the idea of multiple beacons have been studied, other approaches use only one beacon, which […]

Ocean Observatories: An Engineering Challenge

Baggeroer, Arthur B., Bruce M. Howe, Peter N. Mikhalevsky, John Orcutt, and Henrik Schmidt

Observatories are important components for ocean research in most developed countries with a coastline. For many decades oceanographic institutions followed what one might term “expeditionary research”: ships went to places to investigate various ocean processes; observations were made and often sensors were deployed to record data for subsequent retrieval. […]

Summer diatom blooms in the eastern North Pacific gyre investigated with a long-endurance autonomous surface vehicle

Anderson, Emily E., Cara Wilson, Anthony H. Knap, and Tracy A. Villareal

Satellite chlorophyll a (chl a) observations have repeatedly noted summertime phytoplankton blooms in the North Pacific subtropical gyre (NPSG), a region of open ocean that is far removed from any land-derived or Ekman upwelling nutrient sources. These blooms are dominated by N2-fixing diatom-cyanobacteria associations of the diatom genera Rhizosolenia […]
