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

Students will develop research questions that will help them develop an ecosystem profile (species/conditions etc.) of a local pond. Their results will be compared with data from the McMurdo Dry Valley Lakes in Antarctica. Discussions about climate and energy dynamics will be conducted as conclusions are drawn. A map and key for the local pond (species/locations/conditions) will be
During this lesson, students will learn basic glacial features and how to interpret Topographic maps and satellite images in order to create a model replica of a glacier valley. The Dry Valleys of Antarctica have classic glacial features, both in the barren valleys and in the remaining glaciers in the area. The glaciers are a major contributor to

Students are presented with an actual series of tundra photos, which they use to develop a hypothesis for which sort of ground cover will have the most/least permafrost depth. Then they are given a set of actual data and use this to test their hypothesis
Objective
Students will:
* understand what permafrost is and how it develops
This lesson was modeled after some of the routine activities undertaken by the geologists on the Kuril Island Expedition.
Complete the following activities:
* Day 1 To measure a simple topographic profile with a level instrument or hand level and stadium rod.
* Day 2 To use the measurements from Day 1 (and/or actual measurements from the Kuril
This activity is designed to take place near or at the end of a unit on the ocean floor. Students should be familiar with the physical features of the ocean floor including the continental shelf, abyssal plain, seamounts and guyots, seafloor ridges and trenches, and submarine canyons. The students should have also previously learned about sonar methods for mapping the
In this lesson, students learn about what archaeologists do and then practice implementing these skills with "real artifacts".
Objective
Students will:
* be able to define an artifact and an archaeologist.
* use evidence to support their decisions about the origin and use of an unknown item.
