A river runs through it all

We’re in northwest Oregon this time at the mouth of the Columbia River. It’s an example of a coastal margin.

António Baptista says, “One way of thinking about coastal margins is the region where land and sea meet, going from freshwater all the way into the salinity in the ocean.”

Baptista’s the director of the Center for Coastal Margin Observation and Prediction, or CMOP, a collection of Oregon-based research institutions, universities, local colleges, and community groups working together to both predict and influence the coastal margin of the Columbia. And it’s just the latest installment in a river awash with history. Have a listen.



Point Adams fish packing plant lets CMOP hang sensors, tubes and pumps off the end of its pier to collect water samples.

    What would you measure in the Columbia River to assess how healthy it is to support life? What other sorts of questions would you be interested in answering about the river?
