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
By rolling a die, students will simulate a molecule of carbon’s movement with in the carbon cycle. This is a fun, active way to introduce students to the carbon cycle and/or to review the cycle and identify carbon sinks and sources.
Students experience the carbon cycle as CO2 molecules or as stored carbon and travel the path of
In this lesson, students will observe repeat photography samples from Denali National Park that show the change in vegetation over time due to change in climate. This activity introduces students to using observation techniques and visual art vocabulary and skills to create an interactive work of art.
Topics
* Using repeat photography models to document change
*
We hope that this activity will be completed by a multitude of classrooms, students, scientists, and teachers around the world in celebration of International Polar Week - a global celebration of the Polar Regions during the equinoxes each year.

Sea ice, the thin layer of ice that covers most of the Arctic Ocean and surrounds most of the Antarctic continent, represents a distinctive feature of our planet. The attached flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of information about sea ice including sea ice formation, movement, monitoring, seasonal patterns, and forecasting. A follow-up
This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
Students can learn about sea ice—what it is, how it is formed, why it's important, what it impacts, how scientists study it, and what people can do to help slow its melt.
Objective
Students will be able to identify various characteristics of sea ice, how animals and people depend on it, and what scientists learn by studying
