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
SCINI stands for Submersible Capable of under Ice Navigation and Imaging. She is an underwater robot specifically built to complete science missions beneath the frozen surface of the ocean in Antarctica. Learn more about the project, team, and read the "Daily Slog" from the team.
Stacy Kim is a benthic ecologist; she studies the animals that live on and in the seafloor and how they interact with one another in a community. Follow Stacy through blogs, videos, and more via the Ice Stories website.
