Research confirms bottom-feeding behavior of humpback whales
Date:10/30/2013

DURHAM, N.H. Humpback whales are known for the complexity of their feeding techniques, which include "trapping" krill and other prey within bubble nets they produce and gulping up to two-thirds their weight in prey-laden water. Now, scientists have confirmed that humpback whales in the southern Gulf of Maine are spending more feeding time on the ocean floor than in any of these other feeding behaviors. Because entanglement in fishing gear is a major risk to humpbacks, these findings have implications on bottom-set gear like those used in lobster traps.

"Humpbacks have not been known as bottom-feeders, yet this is their dominant feeding mode in this region," says University of New Hampshire professor of data visualization Colin Ware, lead author of a paper published in the journal Marine Mammal Science. "You've got this prominent species, and until now nobody knew how they were doing most of their feeding."

Ware, of UNH's Center for Coastal and Ocean Mapping, and his collaborators, including David Wiley of the Stellwagen Bank National Marine Sanctuary of the National Oceanic and Atmospheric Administration (NOAA) and Ari Friedlaender of Duke University Marine Laboratory and Pratt School of Engineering, gathered data from 52 humpback whales in the Stellwagen Bank National Marine Sanctuary and the Great South Channel near Cape Cod, Mass.

By affixing DTAGs synchronous motion and acoustic recording tags to the whales' backs via four suction cups, the researchers could track for the first time the movements of the whales below the ocean's surface. TrackPlot, a custom software tool developed by Ware, translated the tags' data into a three-dimensional ribbon that illustrated the whales' paths as they repeatedly dove to the bottom of the ocean, rolled onto their sides, tilted their heads down, and feasted on sand lance, a favorite food that is abundant there.

From this data, collected between 2004 and 2009, Ware and his c
