Here’s a unique FREE opportunity for teachers to learn about ocean exploration from NOAA’s College of Exploration.
Here’s the opening paragraph of the course description:
Join NOAA’s Office of Ocean Exploration and Research (OER) for the latest professional development opportunity for educators based upon the voyages of NOAA’s new ship and America’s Ship for Ocean Exploration, the Okeanos Explorer. This offering introduces the second volume of the Okeanos Explorer Education Materials Collection, How Do We Explore?. Topics include searching for anomalies, selecting sites for exploration, communication tools, telepresence technology, mapping techniques, water column study and operating remotely-operated vehicles. This course contains inquiry-based lessons for all grade-levels, and facilitated online reflective conversations about how we approach the study of our largely unexplored ocean.
Teachers can earn 15 hours of professional development credits for FREE. College credit is available for a fee.
My schedule will not permit me to drop into the cafe, at least for the first week. Too bad! It would be a good chance to let participants know more about my 
Seven Wonders of Exploration Technology, which includes a chapter on ocean exploration.
