Hey All, Having a great time in Peurto Penasco Mexico. We have been able to identify and touch several invertibrates living in the intertidal tide pools. Marco,the intern resedent at CEDO,Has been teaching us the history of the Sea of Cortez. It was interesting to learn how big a role the Colorado River played in developing the ecosystem in the Sea of Cortez. The river brought nutrients and seeds of trees and shrubs that help feed the creatures of the Ocean as well as giving shelter for birds.  While I was aware of the ongoing struggles with water rights that affect us locally in Az I was surprised to learn how much the river is needed here. The Colorado River flowed into the Ocean here for the first-time in over 50 years a short time ago. Marco said the impact of that water release has already been seen. Jason Adams.
