Thank you so much @US_APECS for the feature of my short film “Fjord Girls”! This summer I had the opportunity to join Girls* in Icy Fjords in Alaska as an assistant onsite coordinator with @insp_girls_exp. Check out my film documenting that experience below:

Fjord Girls A group of 8 high school girls spend a week in Alaska's Kenai Fjords National Park learning about glaciers, art, and themselves. In Girls* in Icy Fjords, they develop and grow as scientists but also gain confidence in their outdoors skills. youtube.com/watch?v=ukw7BgLs…

A sad day at sea (lake) when my #Bathycat went rogue. Strong offshore winds got the best of me and my RC boat is MIA. If you see an orange castaway on @LakeMichigan13 please contact me! Little guy has gotten me lots of good data and I'd love to get it back! #setadrift #savemyphd – at Milwaukee, WI
