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.
Data visualization from the Multi-scale and Interdisciplinary Study of Humpbacks and Prey (MISHAP) project. Data from a humpback whale track collected using a DTAG attached with suction cups along with sonar data showing krill in the water are combined with GPS tracks to show the big picture of what we were doing. Duke University led the effort while University of New Hampshire provided data visualization.
In 2004, Roland Arsenault received some data from a multibeam sonar mounted on the R/V Coastal Surveyor, a research vessel belonging to UNH's Center for Coastal and Ocean Mapping.
At first, he didn't know what caused the various targets to show up in the water column. But, he says, "it became clear to me once I left a mark in 3D space where those targets appeared. The Coastal Surveyor had sailed over the submerged nets from UNH's Open Ocean Aquaculture program."
