Jean-Michel Cousteau Delights Sold Out Crowd for McCarthy Lecture

On Feb. 6, SCCF hosted ocean explorer, educator, and filmmaker Jean-Michel Cousteau as the speaker for the 8th annual Paul McCarthy Memorial Lecture. The son of French oceanographer Jacques Cousteau, Jean-Michel Cousteau has been exploring the ocean since first being “thrown overboard” by his father at the age of 7 with newly invented SCUBA gear on his back. He has investigated the world’s oceans aboard the famous Calypso and Alcyone expedition vessels; produced over 80 films and countless television specials, public service announcements, and articles; and been a dedicated advocate for the need to act responsibly and preserve the fragile underwater ecosystems that are so intricately tied to all life on earth.
