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
This 1 hour webinar celebrates Antarctica Day 2015 with PolarTREC teacher Michelle Brown and the Human Impacts in Antarctica 2015 expedition. Michelle and her team are on the ice, at McMurdo Station, sharing their research project with the webinar audience.
This one hour webinar features Alex Eilers and the team studying Weddell Seals in the Ross Sea. The team shares their research with the audience and honors the importance of Antarctica Day. The event celebrates the international treaty stating that Antarctica is set aside for peaceful scientific purposes.
This is a one hour webinar hosted by PolarTREC teacher Andre Wille at Toolik Field Station, Alaska. The work presented is part of the Arctic Ground Squirrel Study 2014.
Students are designated as the water or ocean currents, zooplankton, and bowhead whales. The zooplankton are informed that they are at the mercy of the currents. The currents are given instructions as to where to go during different times of the year (map). The whale pod is told that they need to breathe (raise hands above head to indicate
