STEM Network Blog Intro

STEM Professionals' Blog


The GLOBE International STEM professionals Network (GISN) Blog is an online collaborative effort where scientists associated with GLOBE post their thoughts, comments, and philosophies about a variety of science topics.

GLOBE strongly encourages positive and productive discussions to further advance the scientific understanding of all involved with The GLOBE Program.

From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side would move while the other pin stayed in place; when the air cooled, the pin on the other side would be pushed up. The pins were held in place by magnetized strips behind the thermometer tube so that they...

In my previous blog post, I showed the results of my surface temperature experiment. It was a great way to highlight some of the practical ways to use science, and it was yet another way for me to talk about my puppy. My experiment and accompanying blog was straightforward enough. I identified a problem, I designed an experiment, collected data, and presented the results. This is how science is done, right?! With years of experiment experience behind me, this should have been a very fast and easy task, but I had one problem that I forgot to account for, my Attention Deficit Disorder. ...

As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing so on a wide range of time and space scales. In a recent video post, Neil deGrasse Tyson said, “One of the great things about science is that it is an entire exercise finding what is true. You have...

This week’s blog post comes to us from Dr. Janis Steele and Dr. Brooks McCutchen. Drs. Steele and McCutchen, along with their three sons, have been aboard Research Vessel Llyr since April 24, 2013. Read about their adventure in the Intertropical Convergence Zone here. When people think of life in the seas, it is often the majestic that comes to mind, such aswhales, sharks, rays and coral reefs, or our own sustenance in the form of the fish that feed billions of us around the world.  Rarely do we think of plankton, the tiny organisms found across the world's oceans. Plankton are...
