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 lesson is based on studies completed by undergraduate geoscience students working around the glaciers of Kongsfjord, Svalbard during the summer of 2014. It is intended as part of a larger unit on matter that covers atomic theory, atomic structure and the periodic table. Students connect authentic research to their classroom understanding of atoms while learning how this

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
