Latest Event Updates
Just wanted to update all of you on my life situation. I moved! I moved with my fiance Cassie to Lincoln, NE. So the preparation and then the move have kept me very busy, which is why I haven’t been posting anything. Today, we’re moving into a nice townhouse not far from downtown and we’re already in the process of searching for jobs. Once I get settled, I’ll start posting again! In the meantime, school continues and is going well. I’m acing both of my courses, although I have a midterm and quiz due Wednesday morning I have to get through before Spring Break starts. Wish me luck!

Something is clearly going on in Okalahoma—and has been for a while now. Residents have experienced more than 200 quakes with a magnitude of at least 3.0 since the beginning of 2009, and more than 2,600 tremors altogether during 2013. (A 3.0 magnitude quake is considered the threshold at which most people can feel shaking.) According to a recent analysis by EnergyWire, Oklahoma is now the second most seismically active state in the continental U.S., after California.

“This map illustrates the incredible variety of geological features on Ganymede and helps to make order from the apparent chaos of its complex surface,” NASA’s Jet Propulsion Laboratory’s Robert Pappalardo said of the Ganymede map. “This map is helping planetary scientists to decipher the evolution of this icy world and will aid in upcoming spacecraft observations.”

The head of the Geospatial Sciences Center of Excellence (GSCE…the department I work in) sent out a NASA story about the one year anniversary of the Landsat 8 mission…which includes information about the involvement of South Dakota State University, and the GSCE senior scientist Dr. David Roy (the professor I originally interviewed for a position with at the center) who is a co-leader in the USGS-NASA Landsat science team.
You can find the story HERE.
Here is a mosaic image of the United States acquired during the month of August, 2013 by Landsat 8. The satellite is a polar orbiter as opposed to a geostationary orbiter, so the full image of the US was captured on multiple passes with the best cloud-free or minimal cloud cover passes appended together (note: the image is VERY large…so if you click on it blow it up, it may take awhile to load, depending on your internet speed).
Cool story on the near-ice over of Lake Superior going on right now: HERE
Areas of open water were visible Thursday from Duluth, which is normal as the lake ice builds and shifts. Even in 1996, pockets of open water lingered after “virtual ice-over” was officially declared.
If this winter’s cold trend continues, Leshkevich said the lake will virtually freeze over, as it last did in 1996. But he’s not willing to go out on a limb and predict a total freeze-over.
“If it warms up later in February, or we get a lot of wind, then things can change pretty fast,” Leshkevich said. “It’s all dependent on the weather, and I don’t predict that.”
On the other hand, don’t read the comments section. More global warming jokes because it happens to be a cold winter. Seriously, time continues to march on, but the utter lack of understanding of the difference between weather (which involve individual events) and climate (which involve the totals, averages and extremes of those events over some period of time; usually years) continues. The fact that it happens to be cold winter with Lake Superior (for example) experiencing an unusual amount of sea ice over doesn’t take away from the fact that the average temperature of the Earth is continuing a general warming trend (as seen over the scale of hundreds to thousands of years). With all the policy issues involving understanding of global warming, a basic weather and climate course should be required of all students in high school or college (among other important environmental classes which would serious help our society appreciate these issues a lot better). Oh well, too much to ask I suppose…
