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
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
PolarTREC teacher Paula Dell accompanied researcher Kristin O’Brien’s team to Palmer Station in Antarctica for two
months in 2011 to conduct research on antarctic fishes. This article describes their expedition, their evolving collaboration and includes interviews with both Paula Dell and PolarTREC project manager, Janet Warburton.
