The 20 July show featured a conversation with Cascade Sorte and Matt Bracken, visiting scientists at the Sitka Sound Science Center. They study intertidal/marine ecology and have been investigating some of the potential impacts of climate change (including temperature and acidity, both of which they are looking at in a experiment they are running on a local beach while visiting the science center).
If you have questions or observations you want to share, please feel free to leave a comment here or on the page I’ve set up for that purpose.
