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!

Right whale map

These are the latest sightings and acoustic detections of right whale in Atlantic Canada over the last 2 weeks. I built this summary map as well as a more comprehensive interactive map to help collate, interpret, and disseminate right whale survey information in the region.
