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
This archive is for Webinar 2 focusing on pre-field preparations and activities for the 2017-18 PolarTREC Arctic cohort. This event was held on 4 April 2017.
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
Teacher Josh Heward discusses research with the "Tough Tardigrades Team" in the McMurdo Dry Valleys in Antarctica where they search for tardigrades and other microorganisms that live in the soil.
Teacher Tim Dwyer discusses the Antarctica Treaty in conjunction with Antarctica Day 2016. He and Dr. Art Woods also discuss the research being done on Polar Gigantism on sea spiders based out of McMurdo Station.
