This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
ScienceNews article highlighting the work of Polar Gigantism in Antarctica expedition Principal Investigator Dr. H. Arthur Woods on sea spider physiology.
President Obama recently named 102 researchers as recipients of the Presidential Early Career Awards for Scientists and Engineers, the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their independent research careers. Researcher Samantha Hansen, who worked for two field seasons in Antarctic with PolarTREC teacher Brian DuBay will be one
This video clip from from Alabama TV 13 News profiles PolarTREC researcher Dr. Samantha Hansen's work studying the history of landforms in Antarctica. Dr. Hansen will be one of a hundred scientists to be awarded the Presidential Early Career Awards for Scientists and Engineers.
Researcher Egbert Schwartz and PolarTREC teacher Justin Kendhammer will travel to the Dry Valleys of Antarctica in search of life in the seemingly barren soil. One of the questions they will attempt to answer is whether microbes in the soil are native to Antarctic soil or whether they have been blown onto the continent from elsewhere in the world.
We go places, but what do we do with the billions of snippets of information we absorb? How do we process the information so that it means something to us when we can no longer be there? As a geographer, my objective was to be able to observe, participate and categorize the billions of pieces of visual information
