My name is Hansen Johnson. I'm a PhD student at Dalhousie University, and a guest student at the Woods Hole Oceanographic Institution where I'm advised by Dr. Chris Taggart and Dr. Mark Baumgartner, respectively. I study baleen whale acoustic and habitat ecology in the Northwest Atlantic. I use this site to share some aspects of my research and some helpful tools of the trade. Occasionally I also write posts about things I think are worth remembering or sharing. If you're interested in any of this stuff, please don't hesitate to get in touch!
