This lesson introduces students to the impacts of increasing ocean temperatures on marine life. Through this kinesthetic activity, students will learn more about marine ectotherms and what researchers in Antarctica have learned so far about how increasing temperature in Antarctic waters will affect their growth. Through the elaborate section of the activity students will connect what they learned about
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.
