Don't Panic Geocast

This week Dr. Uri ten Brink joins us to talk about his field experiences as an observational geophysicst and some thoughts about being a scientist. (Sorry, no fun paper this week - we were not able to record it before Shannon’s leave of absense!)

Shannon just had a baby! We take the week off and celebrate with this classic episode of the geocast... Don't Panic, we'll be back next week! Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers. Oroville (1968) is the tallest in the US, and earthen dam in CA 770’ high Hoover (1935) is next at 726’ high on the border of AZ and NV Tallest dam in the world is Jingping-I dam (2013) in China is 1000’ high Largest reservoir in the US is Lake Mead, which holds 29 million acre-feet of water Glen Canyon dam Lake Powell on the AZ/UT border, and is a close second at 26 million acre-feet capacity. Colorado River WPA Why build dams at all? Water supply Irrigation and flood control Power supply Recreation Hydroelectric Power Hoover dam generates 4.5 bil

  John is installing his weather station and Shannon is still pushing through finals week. On this week’s show we talk about a listener question regarding fulgurites.
