TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of December 4, 2017.

MUSIC – ~8 sec

This week, that excerpt from “Mountain Stream,” by Bob Gramann of Fredericksburg, accompanied by Laura Lengnick, opens our examination of the most upstream part of watersheds—the highest areas where water starts following a channel and flowing overland towards rivers.  Have a listen for about 10 seconds to two Virginia examples, and see if you can guess this watershed feature.  And here’s a hint: get this right and you’ll stream to the head of water class.

SOUND - ~ 10 sec

If you guessed headwater streams, you’re right!  Headwater streams are the first flowing waters in the upper part of a river’s watershed.  These relatively small streams have a big range of functions, including as habitat for certain organisms or life stages, and as a source of water, materials, and organisms for downstream waters.

Understanding the location and length of headwater streams in the Appalachian Mountains, particularly in response to storms, is the research goal of Carrie Jensen, a graduate student in Virginia Tech’s Department of Forest Resources and Environmental Conservation.   In early November 2017, Ms. Jensen described her research and its significance in just 90 seconds during the “Nutshell Games,” held by Tech’s Center for Communicating Science.  Here’s Ms. Jensen’s presentation.

VOICE - ~89 sec

As Ms. Jensen’s work shows, there’s much to know about headwaters, and such information can help us better understand quantity and quality patterns far downstream.

Thanks to Carrie Jensen for permission to use the audio from her talk.  Thanks also to Bob Gramann for this week’s music, and we close with about 20 more seconds of “Mountain Stream.”

MUSIC - ~18 sec

SHIP’S BELL

AUDIO NOTES AND ACKNOWLEDGEMENTS

The audio of Carrie Jensen was derived from the video of her presentation at the Second Annual Nutshell Games conducted on November 4, 2017, at Virginia Tech in Blacksburg.  The videos from that day are available online at https://www.youtube.com/playlist?list=UU01cz4Mal3-AOZeODCauLHw (as of 11/30/17).

The Nutshell Games are organized by the Virginia Tech Center for Communicating Science to give graduate students a forum for describing their research in a short presentation designed for non-scientists.  More information about the Center for Communicating Science is available online at https://communicatingscience.isce.vt.edu/.  Two news articles about the Nutshell Games are New center focuses on the art of communicating science effectively, Virginia Tech News, 2/28/17; and Understandable communication aim of first 'Nutshell Games', Roanoke Times, 3/3/17.  For another Virginia Water Radio episode featuring a Nutshell Games presentation, please see Episode 376, 7-10-17.

“Mountain Stream,” from the 2001 album “See Further in the Darkness,” is copyright by Bob Gramann; used with permission. Laura Lengnick accompanied on fiddle.  This selection was also used in Virginia Water Radio Episode 156 (4-8-13) and Episode 209 (4-14-14).

The sounds of headwater streams heard in this episode were recorded in Blacksburg, Va.’s Heritage Park on July 27, 2016, and in Blacksburg on Brush Mountain on January 31, 2010 (the latter stream is shown in the photos below).

Click here if you’d like to hear the full version (1 min./11 sec.) of the “Cripple Creek” arrangement/performance by Stewart Scales that opens and closes this episode.   More information about Mr. Scales and the group New Standard, with which Mr. Scales plays, is available online at http://newstandardbluegrass.com.
