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

Do Microorganisms Live in Antarctica?

Overview

We know that we have lots of microorganisms growing where we live, but can microorganisms like bacteria also live in the harsh, cold, dry climate of Antarctica? Part of our research project in Antarctica is looking at the microorganisms that live in the Taylor Glacier. We are taking dirty ice (ice with lots of dirt/sediment in it) and

Is There Salt in a Glacier?

Overview

For this experiment, we are going to melt dirty ice (ice with lots of sediment/dirt in it) and clean ice (ice without sediment) from the Taylor Glacier. After we melt the ice, we are going to test the melt water for pH and conductivity, and then determine how much salt is actually in our ice samples. There are
