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 incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
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
Students in cooperative teams will use a spreadsheet and graphing program such as Google Sheets or Microsoft Excel to graph and evaluate a large data set. The data sets provided come from authentic arctic ground squirrel research completed at Toolik Research station in arctic Alaska. The data sets were downloaded from body temperature loggers implanted into individual animals

This is a one hour webinar hosted by PolarTREC teacher Andre Wille at Toolik Field Station, Alaska. The work presented is part of the Arctic Ground Squirrel Study 2014.
The Dry Valleys region in Antarctica is known as the coldest, windiest, driest place on Earth. Beacon Valley is famous for its katabatic winds which can routinely knock fit adults and PolarTREC teachers to the ground. This lesson was created by PolarTREC teacher Jacquelyn Hams who experienced the cold and the full force of the winds in 2008
