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
At Summit Station, Greenland, science technicians measure the snow conditions of the runway to determine if the LC-130 aircraft which brings supplies and people in and out of Summit can land and takeoff safely.
Students can use data taken by technicians at Summit Station, Greenland and develop a model to determine if snowpack conditions on the runway are sufficient
This one hour live event is hosted by PolarTREC teacher Lisa Seff and her team studying the oceanographic conditions of bowhead whale habitat. The team is stationed in Barrow, Alaska.
This lesson investigates the impact of melting and freezing arctic sea ice on the properties of salinity, temperature and density that contribute to the stratification of ocean waters. This lesson combines several learning approaches including a hands-on lab, a web-quest and collaboration with other students.
Objectives
1. Students will be able to explain and demonstrate how Arctic
