Summary of Accomplishments:
During the summer of 2006 White analyzed data from simultaneously tagged long-finned pilot whales to quantify how these animals use the sonic environment to coordinate group behaviors. A group of three synchronously diving, cross-audible pilot whales was identified from a 2004 DTAG data set. A generalized time difference of arrival (TDOA) acoustic transponder approach was used to calculate estimates for the distance between each pair of animals during the synchronized dive cycle. From these distance estimates, a dynamic baseline was established to later track untagged whales in the synchronized group.
White also participated in the Stellwagen Bank National Marine Sanctuary 2006 Humpback DTAG tagging cruise (P.I. David Wiley). On this cruise his responsibilities included field support in the tagging and tracking of humpbacks in the sanctuary and analysis of data upon the retrieval of tags.
