Lubricating the Action

Date: 
Mar 24 2008 7:30pm - 9:00pm
Event Description: 

Earth’s Secrets Revealed: Professor Martin Saar from the University of Minnesota discusses the role of fluids in geology.

Fluids play an important role in geologic processes. In this presentation, I will discuss some of the fluids that are being studied in the Geofluids Research Group which include groundwater in aquifers and karst (cave) systems, magma/lava, and gases (e.g., volatiles in magmas). The types of questions the Geofluids group tries to answer are: 1) How much groundwater is flowing from where to where at what rate with implications for drinking and irrigation water supply? 2) Where is renewable geothermal energy usage possible? 3) Can the greenhouse gas CO2 be stored in saline aquifers? 4) How fast do caves form in Minnesota’s SE karst system and how fast do water and contaminants move through karst caves? and 5) What are the effects of magma permeability on volatile degassing rates and related volcanic eruption dynamics? At the end of this talk I hope to have conveyed that there are more fluids in geology than one commonly considers and that they play an important role in many geologic processes.

Free cookies and a Q&A session will follow the illustrated talk. Lecture should be technically understandable for high school students to adults, and may qualify for extra credit for students and CEUs for teachers.

Schedule:
7:30-8:30 pm – lecture
8:30-9:00 pm – cookie break/Q&A

Stories We're Working On

In progress

These are some of the stories we are working on. We invite and encourage you to contribute to these stories, or to suggest other stories that you would like to see covered.

REPORTER’S NOTEBOOK | North Minneapolis We’ll tell you what the judge decides on the flurry of lawsuits around last winter’s Jordan Area Community Council controversy as soon as the decision is made (probably the week of July 6). What do you think about what’s been going on at JACC, in Jordan, and around the Northside? Tell us what you know – and what you think we should be covering.

REPORTER’S NOTEBOOK | Background checks bar park volunteers
Minneapolis parks have recently tightened enforcement of rules about background checks for volunteers. But does the “systemic bias of the criminal justice system” mean that many African American males will be barred from serving as volunteers? We want to hear your ideas.

REPORTER’S NOTEBOOK | Hmong Freedom Celebration and Sports Tournament Coming up this weekend! We’re looking for community input about the sports tournament, your experiences at the tournament, how it has changed over the years, what the gathering of Hmong from around the country and around the world means, and any other thoughts you might have about the weekend.

MUSIC | Black Blondie and Foxy Tann knock 'em dead at the Uptown Pride Block Party

By Dwight Hobbes , TC Daily Planet

The Uptown Pride Block Party on June 26 was an LGBT Pride Week affair, but you didn’t need to be lesbian, gay, bisexual, or transgender to get with it. For that matter, you didn’t have to have a dime in your pocket. All you had to bring was the willingness to enjoy a damned good time. MORE »
