In this activity, students will use data collected about two male arctic ground squirrels by researchers at Toolik Field Station in northern Alaska. Each squirrel had a lightlogger to record light intensity (lux) and an implanted data logger to record internal body temperature (°C). Students work individually or in pairs to analyze the data sets and interpret the results
This lesson is intended to help students make connections to polar science while discovering how and why sea ice drives deep ocean currents. Students will also learn key terminology related to sea ice and using actual salinity content charts, will graph a typical sea ice core’s salinity as it relates to depth.
This lesson allows students to learn about the Arctic through a challenging question and answer game format. Inspired by experiences in the Hidden Ocean 2016: Chukchi Borderlands expedition, the game includes “careers”, “animals”, “equipment”, “climate change”, and “geography” components. The game may be used as a learning tool, a review tool, or an assessment tool.
In this webquest, students use maps to relate global temperature change to changes in the range of insects and birds and projected changes in tree range. The activity could be used to teach a lesson via class discussion and/or written response; it could be completed by students in cooperative groups on paper or with shared computers; on the other
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
One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
