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
Scientists use bathymetry to understand the ocean floor. This lesson is a basic introduction to bathymetry using salad trays to help students understand how bathymetric maps work.
Objectives
1. Students will be able to identify the advantages to using a bathymetric map.
2. Students will be able to transform a bathymetric map into a three-dimensional model.
3. Using just
Beacon Valley is recognized by scientists as one of the most Mars-like environments on Earth. This lesson plan was created so that students could have the opportunity to examine the same landforms that scientists use to study the processes that operate in both of these extreme environments. There are two parts to this lesson. Teachers may choose to
