Chlorophyll Conundrum: Can factors affect chlorophyll levels in plankton samples?

Overview

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

Reeling in CTD Data

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
