Studying humpback whales from the NOAA ship Nancy Foster in 2006. Two whales had DTAGs attached using suction cups that measured depth, acceleration and the magnetic field while recording sound. Tracks were reconstructed from the data and combined with GPS and sonar data into this visualization. Bubbles can be heard in the sound record and the whales can be seen working together feeding where the echo sounder is showing prey in the water. The research was led by David Wiley from NOAA's Stellwagen Bank National Marine Sanctuary and the visualization provided by UNH's Center for Coastal and Ocean Mapping.
