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
Ground Penetrating Radar (GPR):
Seeing Below the Surface While Keeping Scientists Safe
Overview
Ground Penetrating Radar (GPR) is a valuable technology that utilizes waves of low frequency electromagnetic radiation to help polar scientists understand what is beneath their feet! Using real field data from the Icelandic glacier Múlajökull, along with a small selection of short videos and web-based resources
Here is a great interview with Dr. Iverson on Iowa Public Radio. He gives an excellent overview of the research, why he has chosen Mulajokull as a location, and the significance of understanding glacial mechanics and movement in light of global climate change.
This article describes PolarTREC teacher Nick LaFave's upcoming expedition to Toolik Lake, Alaska where he will be studying wolf spider populations with Duke University researcher, Amanda Koltz.
ANDRILL (ANtarctic geological DRILLing) has drilled and recovered thousands of meters of rock core from beneath the McMurdo Ice Shelf in Antarctica. What secrets are hidden in this rock? Why do scientists from around the world work together to uncover these secrets that have been shrouded beneath the ice for millions of years? Join this real world geoscience adventure in
A young marine biologist from Portugal shows the science, the beauty and the importance of the polar regions to the planet from a research cruise en route to Antarctica. Film is primarily in Portuguese with some English.
Tunnel Man is a super hero who lives in Ice Tunnels, and teaches children and adults about the unique geomorphology of Alaska. Tunnel Man is played by Kenji Yoshikawa, a Research Associate Professor for the Institute of Northern Engineering at the University of Alaska Fairbanks (UAF). Tunnel Man's fun and educational videos were produced as part of UAF's participation in
