Byrds Mill Spring Dive Video

This is a 2.5 minute video showing the inside of Byrds Mill Spring and the bubbles effervescing from the floor of the spring. Shannon Wallace, an experienced cave diver, took this underwater footage in November 2005 during a research expedition to sample water directly from the springļæ½s source. (The tube through which the sample was obtained can be seen in the video.)

The bubbles are composed primarily of nitrogen and carbon dioxide gas, which occur naturally in the aquifer. For more information, see An Inside Look at Byrds Mill Spring in the Arbuckle-Simpson Hydrology Study March 2007 newsletter.
