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
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
