This is a project of The Foundation for Antarctic Research, Inc. The project is a 5-year study to better understand the impacts of Krill fishing and global warming on this northern-most colony of Emperors. The ice is melting and the decrease in Krill will most certainly see the end of this colony - sooner than later.
