DEPTH PROFILE

Objectives
Logistics
This project aimed at measuring and mapping water depth of the wetlands. Students grouped themselves into teams of four and each team was responsible for measuring the water depth along selected transects along the wetlands. Prior to mapping the wetlands, the class spent a lab period discussing how to set up a grid, and why it was important to set up a grid before taking measurements (i.e., so the measurements are evenly spaced). We also clearly defined the procedure for measuring water depth in advance: from a canoe, the students would drop a marked rope (anchored with a weight on one end) to measure water depth. Each team consisted of three canoeists (2 paddlers & one person to measure water depth) and one shore-support person (to record data & help orient the canoeists). After the data were collected, an additional lab period was spent making contour maps and cross-sectional profiles, both by hand and by computer.
