In collaboration with acousticians and students from Cornell University and marine biologist from Hawaii Marine Mammal Consortium, we conducted a “proof of concept” test using 3 Wave Gliders equipped with hydrophones to triangulate on a singing humpback whale off the Kohala Coast. The data are still being analyzed, but the preliminary results of being able to identify bearing and distance of a whale or other audible targets appear to be very promising. More test to come.
We loaded up 3 WG’s on May Maru

We ended up performing the test in gale force winds, a testament to the WG’s, students and May Maru!
