The Discovery of Greenland’s Massive Canyon

NASA scientists have recently discovered a canyon underneath Greenland’s ice sheet by using radar data. The canyon is 400 miles long and half a mile deep (for comparison, the Grand Canyon is 277 miles long and a little over a mile deep). This canyon was believed to have been formed before the glacier over Greenland formed.

Radar uses electromagnetic waves to penetrate through the ice. In much the same way that shining a flashlight through a window to a wall will case light to reflect off of the wall back to the person holding the flashlight outside, the longer radio waves used with radar reflect off of the earth’s surface.

It is definitely interesting to learn about this canyon, but the importance of the discovery is beyond being a neat fact. Water flowing beneath the glaciers actually contributes to a complex relationship with glacial movement and melting, and the transport of glacial melt water from inland portions of the glacier to the ocean is pertinent to this topic.

It’s still a trend though, right? Right?

Sure, just find a periodic function to fit this data. Be sure to include that last part. Then we can talk.

NSF Science Must “Directly Benefit the American People”


It already does, but Representative Lamar Smith thinks that there are many scientists that are schemers out to steal money from the government. In fact, he decided to pick out a few projects that didn’t interest him to use as examples of how NSF just throws money to “useless” research.

Additionally, he would like Congress to get involved in the peer review process, because congress has such great track record of being efficient and solving problems. When we start moving away from the peer review process, and into the “I am judging this research based on my feelings, even though I am a politician and not a scientist” process, problems arise. Scientists work very hard to convey research to the public as well as agencies such as NSF. However, many fields go into such intricate detail that it is necessary to have other people in the field review the scientific project proposed. Many researchers are adding a tiny grain of sand to the astoundingly large world of research. Some research leads to things that we don’t notice like an improved polymer, or a tiny addition to a huge model of the climate, or a small statistical study that opens up new questions about the ways in which we are currently running our society.

Lamar Smith is a climate change critic, a trendy thing in the Republican Party. This goes to show that he is not spending a lot of time delving into the research itself, and attempting to understand it. I am happy that he at least read through some of the NSF proposals, but what he should really spend time doing is reading some of the peer reviewed papers that have come out of research, and the citations of those papers.


The Loss of Arctic Ice Contributes to Extreme Weather

This is an excellent video describing loss of Arctic sea ice. In 2012, more Arctic sea ice was lost than any other year of modern measurements. The implications of this may be farther reaching than we thought, as our weather patterns have a dependence on Arctic sea ice. A more in depth discussion of this video can be found at Nation of Change.
