This is a revised version of an episode from January 2016. MUSIC – ~9 sec – instrumental. In this episode, we use music by a Blacksburg, Va., singer-songwriter to help us dive underwater. Have a listen for about 55 seconds. MUSIC - ~54 sec – Lyrics: “Endless water calls to you. Falling backward into blue. Lovers breathing, adapting, reaching, receiving. Bubbles lifting, creatures sweeping into view; you’re an alien at sea. Scuba dive; scuba dive.” You’ve been listening to part of “Scuba Dive,” by Kat Mills, on the 2015 album “Silver.” Ms. Mills’ lyrics use the challenges and thrills of underwater diving as metaphors for exploration and trust in human relationships. While human interactions can be quite unpredictable, the main challenges of the underwater environment come from several predictable physical, chemical, and biological properties of deep water. Water’s density affects vision and hearing underwater. Buoyancy—resulting from the density of a submerged object compared to the density of the surrounding water—must be adjusted for moving up or down. Movement is also affected by the frictional resistance of water, or drag. Pressure from the weight of the water affects a diver’s lungs, sinuses, and ears, as well as the levels of oxygen, nitrogen, and other gases dissolved in the water and in one’s blood. Temperature affects dissolved gases, too, along with presenting a body-heat challenge. Divers can become partially dehydrated through breathing dehumidified compressed air. And dangerous aquatic organisms may await. Adapting to those challenges through underwater breathing devices, other equipment, training, and experience allows divers to enjoy the exhilaration of feeling weightless, seeing fascinating creatures, and exploring worlds most humans never see. Add in some trust and overcoming of one’s fears, and people continue to fall backwards into endless blue water, literally and figuratively. Thanks to Kat Mills for permission to use this episode’s music, and we close with about 30 more seconds of “Scuba Dive.” MUSIC - ~30 sec – Lyrics: “Scuba dive.” SHIP’S BELL Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.
