New publication!

We are pleased to announce the publication of the following article:

Witteveen, B.H., A. De Robertis, L. Guo, and K.M. Wynne. 2014. Using dive behavior and active acoustics to assess prey use and partitioning by fin and humpback whales near Kodiak Island, Alaska. Marine Mammal Science 31(1): 255–278.

This article describes prey use and potential prey partitioning between fin and humpback whales by combining analysis of vertical whale distribution obtained from tagged individual whales with concurrent assessment of pelagic prey.

Dana WrightGAP welcomes new graduate student!


The GAP project is pleased to welcome Dana Wright as a master’s student. Dana comes to the project after receiving a B.S. in Marine and Aquatic Sciences from the University of Maine in May 2012. During her tenure at UM, she received a prestigious NOAA National Hollings Scholarship in 2010 and was also Division I swimmer.  Dana’s project will be to revise and update abundance estimates of humpback whales around Kodiak Island while also exploring fine scale differences in their stable isotope signatures.

The Baranov Museums hosts “Thar She Blows!”


Kodiak’s own Baranov Museum hosted Bree Witteveen as she summarized 12 years of whale research around the Emerald Island. The talk was a free event open to the public made possible by a grant from the National Park Foundation.

CTD castGAP completes 2012 vessel-based surveys


GAP researchers completed 15 days of vessel based surveys throughout the Kodiak archipelago. The purpose of these surveys was to document whale distribution and relative abundance while concurrently documenting prey availability through hydroacoustics and oceanographic conditions using CTD casts.  Kate Wynne and Bree Witteveen led the whale component of these surveys and collected photographs and biopsy samples of individual fin and humpback whales. The prey assessment and oceanographic component of the surveys were led by Lei Guo. While the researchers hoped to tag whales as well, weather conditions did not allow for this to occur. These surveys will continue in 2013.
