The IslandCT podcast is a podcast about science, nature, technology, and education hosted by Kelly L. Sears and Patrick R. Sears. It is published every other week and was started in January 2015.
The show topics covers most of the topics discussed in order. The show title denotes only one of the topics discussed; its meant to act as a mental peg rather than a description of the podcast content. See the the podcast minutes web page for a more detailed time-stamped list of topics. Be warned, it's a bit messy.
We have mostly completed migrating the podcasts from our older server. Some of the topic lists are incomplete or missing but all the podcasts that will be migrated are here.
For comments, suggestions, and questions; please contact frontal[dot]harvest[dot]25[at]gmail[dot]com.
