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 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world.

We’ve had a fairly active hurricane season, so we thought that maybe now would be a good time to discuss what exactly a hurricane is, especially for those of us non-coastal dwellers who maybe don’t think about them as much as say…tornadoes!

Earthquake! Last week Oklahoma was rocked by the largest recorded earthquake recorded in the state’s history. We talk with Dr. Katie Keranen who is in the field deploying seismic instruments to study the event. Sorry for the audio quality this week - we were recoding the interview as a phone call since Dr. Keranen was in the field and there are occasional dropouts.

We are teaching and traveling with the start of the semester. Since John has no solid cell phone signal at a conference in New Hampshire and Shannon is swimming in lecturing, we wanted to share one of our favorite interviews from this year! This week a special guest takes us to the moon by talking about lunar rocks and meteorites! The moon turns out to be a fascinating place, but probably won’t break up like in Seveneves.

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 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world.

Forecasting the weather is tricky business. You need a lot of information. While surface observations can get us a lot of data, we still need information about what is happening far into the atmosphere to make meaningful models and predictions. Thats where weather balloons come in. This week we talk about how upper air observation works as well as Jupiter’s atmosphere on Fun Paper Friday!
