    This week we continue the Earth Optimism Series, a 24-episode project in partnership with the Smithsonian Institution's Ocean Portal, to address ocean solutions and innovative projects in the context of the Earth Optimism Summit, April 2017. In this episode, host Peter Neill discusses the need for more funding and energy directed toward the vast unknown ocean, and the importance of scientific endeavor and observation. He introduces us to the General Bathymetric Chart for the Oceans (GEBCO), a project dedicated to completing the full mapping of the world ocean by 2030.

About the Earth Optimism Summit
April 21 - 23, 2017

The Earth Optimism Summit, sponsored by the Smithsonian Institute’s Ocean Portal, will be an unprecedented gathering of thought leaders, practitioners, pioneering scientists and researchers, major civic and industry participants, national and international media, and philanthropists who make up the conservation-minded citizens of our world. They will convene to discuss and share solutions – what are the best minds, boldest experiments, and most innovative community practices telling us about how to preserve biodiversity, protect natural resources, and address climate change?

The Earth Optimism Series is brought to you by the World Ocean Observatory in partnership with the Smithsonian Institution’s Ocean Portal, to raise awareness of the Earth Optimism Summit during Earth Day weekend, April 21-23, 2017 in Washington, D.C. and around the world. Share your ideas at
