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 activity is 4 of 4 in a series that exposes students to the concepts of and work done by the HERMYs Project (Historical Ecology and Risk Management: Youth Sustainability):
1. A Narrative Pantomime
2. Environmental Risk Assessment
3. Risk Hazard Identification
4. Local and Traditional Knowledge & Risk
*“Historical accounts of remote Alaska can only offer documentation

There is so much media hype and public misunderstanding regarding the issue of climate change that advanced students need to be equipped to sort through the information available, find data from appropriately moderated scientific data bases, and learn to support their views with good scientific evidence rather than emotion. This lesson provides the outline for giving students some preliminary
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
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
