For Learners

Observe. Understand. Participate.

The writer, John Steinbeck, and marine biologist, Ed Ricketts, made observations about the world around them. Making observations, and discussing them together, allowed them to gain a deep understanding about nature and human communities. Steinbeck and Ricketts also valued participation. They went beyond observing and understanding the communities around them. They got involved.

The Western Flyer Foundation invites you to follow in the footsteps of Steinbeck and Ricketts. Check back here for ways to make observations, to deeply understand, and to fully participate in the world around you!


Intertidal Zone Bioblitz


In 1940, John Steinbeck and Ed Ricketts chartered a purse seiner, the Western Flyer, for a 6-week expedition to the Sea of Cortez. They captured and catalogued marine invertebrates (animals without backbones) at 21 different sites along their route. In 1941, the two friends published Sea of Cortez, a narrative account of their journey and a “phyletic catalogue”of all the species they found. The catalogue includes 484 species of marine invertebrates!

This summer, the Western Flyer Foundation invites you to take an expedition to your local coastline to catalogue and identify as many marine invertebrates as you can using iNaturalistFor more information and a field guide, please visit the Intertidal Zone Bioblitz Portal.
