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

Exploring the Ocean: CTDs

Overview

Oceanography is the study of the ocean. It covers a wide range of topics from marine life to the geology of the sea floor to the physical properties of the ocean. Physical oceanographers study the physical components of the ocean including light, waves, tides, currents and the composition of sea water. The physical properties of the ocean can

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

Almost Fool-Proof Cloud Chamber

Overview

This activity is a way to create a cloud chamber in the classroom. A cloud chamber allows students to view "invisible" alpha particles emitted through nuclear decay. Alpha particles have a long history in nuclear physics--they are a helium nucleus and their emission during nuclear decay was one of the first ways we knew that atomic nuclei could
