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.
1. Use models to predict chlorophyll levels in the global oceans
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
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
Quincy Access Television interview: PolarTREC teacher Cara Pekarcik talks with Joe Catalano on the Currently in Quincy Program. The conversation includes descriptions of the PolarTREC program, a description of the research project and day-to-day activities as well as a discussion about student and community outreach.
