Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
After spending 5 weeks in the Arctic learning about tundra vegetation and phenology, Alejandra Martinez wanted to have her students observe the growth of plants in their school. In this lesson, students will grow plants in multiple locations and track their growth to compare their phenology.
Objectives
Students will learn what phenology is and make observations about plant growth
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
Ground Penetrating Radar (GPR):
Seeing Below the Surface While Keeping Scientists Safe
Overview
Ground Penetrating Radar (GPR) is a valuable technology that utilizes waves of low frequency electromagnetic radiation to help polar scientists understand what is beneath their feet! Using real field data from the Icelandic glacier Múlajökull, along with a small selection of short videos and web-based resources
