Lab 2

In this lab the class took a trip to the Ocmulgee River and gathered data in two different areas. The first area was the number of clams found in different places across the width of the river. In the photo below, the number on each marker indicates the number of clams found in each sand sample that was taken. The filled dots represent zero clams.

Also note that since the imagery from Google Earth is not current, so this is an approximation. A white shape has also been added to represent an additional sand bank that otherwise does not appear in the image.

The other area in which data was collected was the height of the riverbed. Measurements were made from one side of the river to the other, with the initial riverbank height set as zero elevation. In the picture below, the number by each marker gives how many feet below the initial height each point was measured to be. The markers are placed to be in approximately 50 foot intervals.

The actual measurements were made in 10 foot increments, however, and so a graph (shown below) was created by Dr. Rood using all the measurements to help give a more accurate feel for the elevation changes across the river's width.
