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.

Quaking aspens can grow in a wide range of environmental conditions. They can tolerate a wide variety of variations in climate and environmental conditions including slope, moisture, surrounding vegetation, and soil (https://www.fs.fed.us/wildflowers/beauty/aspen/ecology.shtml). I found this information with a simple web search. But, before there was access to infinite articles, websites, and papers all a click away, scientists had to figure out growth trends using data. So, before I decided to do a web search about the environmental conditions of aspen habitats (my memorized aspen facts...

I recently had the pleasure of meeting a GLOBE student named Aspen. I was excited because my favorite type of tree is Aspen (Quaking Aspen to be more specific, Populus tremuloides to be even more specific), and I was able to tell her some of the fun facts about her namesake. My favorite thing about aspens is their bark. The white powder on it can act as sunscreen. It’s only about an SPF of 5 but it’s still pretty cool. The bark also contains chloroplasts which means it can photosynthesize, making it one of the few deciduous trees that do not solely rely on leaves for photosynthesis. They...

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...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2 mm of rain fills the inner tube to a depth of 2.0 mm, which one can read. In addition, if heavy rainfall fills the inner cylinder, the rest of the rainfall overflows into the outer cylinder, which...

This time was my first visit to Trinidad and Tobago and to the LAC region. The visit was first of its kinds, knowing vividly that Africans and the People of Trinidad and Tobago have so many things in common in terms of Geography and Historical antecedent.  The motivation for my visit to Trinidad and Tobago started during the 17th GLOBE Annual meeting at Maryland. Initially, it was just a brief discussion with Henry Saunders (Country Coordinator, GLOBE Trinidad and Tobago). However, after a year, I met Mr. Michael at GLOBE Expedition in New Delhi, India where we had in-depth discussions...
