Since Memphis, Tennessee is the blues music capital of the world, just upriver from the jazz music capital in New Orleans and a short distance from Nashville, TN, the country music capital, it seemed appropriate to capture our lower Mississippi River workshop in the form of a blues song. Memphis is where Sam Phillips at Sun Records recorded such music luminaries as Elvis Presley, Johnny Cash, Jerry Lee Lewis and Carl Perkins.

Once again, a contingent from IAN (Heath Kelsey, Bill Nuttle, Caroline Wicks, Brianne Walsh and me) gathered along the banks of the mighty Mississippi River to meet with a diverse stakeholder group to discuss the issues associated with the Mississippi River. In this case, we learned about the issues associated with the lower Mississippi River, which were surprisingly different from the issues in the Upper Mississippi River and the Ohio and Tennessee Rivers from our previous workshops.

Report card goals relate to benefits provided by coexisting natural ecosystems and human-built infrastructure. The problem is that the Ohio River is a working river. That thought occurred to me as I watched the barges glide past the window during the Ohio River report card workshop last December. A team of IAN science communicators spent two days on the banks of the Ohio River, across from Cincinnati, gathering information from experts on the Ohio and Tennessee River basins.

Following our Connecticut stops, we took the Cross Sound Ferry from New London, CT over to the tip of the north fork of Long Island at Orient Point. From the ferry we could see some important features of Long Island Sound. First, as we sailed out of the Thames River, we could see the rocky headlands, industrial development (particularly the submarine manufacturing base) and busy harbor traffic.
