Eustacy is a word used to describe worldwide changes of sea level. This is a new word for us: even though it seems we live in a eustatic world. We're using this newly-discovered word to distill the five areas of our existence where the ocean matters most: fresh water, the ocean-fresh water continuum, energy, food, health, and exchange.

About World Ocean Radio
World Ocean Radio is a weekly series of five-minute audio essays available for syndicated use at no cost by college and community radio stations worldwide, providing coverage of a broad spectrum of ocean issues from science and education to advocacy and exemplary projects. Episodes of World Ocean Radio offer perspectives on global ocean issues and viable solutions, and celebrate exemplary projects.

Some of the world’s greatest innovations were born from unexpected conversations rather than scheduled meetings. Ideas often emerge not during presentations but in hallways, kitchens, cafés, and shared lunch tables. This week we're discussing Thor Sigfusson's new book "The Incredible Coffee Machine, Where Mission, Space and Innovation Meet" and the ways informal encounters can reshape entire industries.

This week marks the 800th edition of World Ocean Radio. We began broadcasting in 2009 on Community Radio, WERU 89.9 FM in Blue Hill, Maine, USA. We thank the WERU management and trustees for their initial confidence in this project, and to all listeners and Citizens of the Ocean around the world, for tuning in and responding so positively. Adora Maris translates from the Latin as “worship of the sea,” reflecting cultural reverence of and for the ocean. Thanks for listening. The sea connects all things.
