Lab #2

In lab #2 we went to the Ocmulgee River in Macon.  The map above is a picture from Google Earth. The white box marks the outline of shallow water/ sand.  Based on the time of year this level changes, however this is what the land looked like during our lab. During our Lab we looked at the number of clams in different areas of the river as well as the difference in elevation across the river.

The blue balloons are used to represent the places that clams were dug up. We used a shovel to dig under the surface, and then placed to dug up dirt in a pan, allowing us to find the clams. The blue number next to the icon is the number of live clams that were found. By mapping out the number of clams we are able to infer that clams prefer to live in areas that are neither shallow nor deep, and in medium water flow areas. They do not want to live too far under the water, but not on top in the sand. The slower currents, close to the shallow water level, provided a better living environment for them, which is why more were found in the slow current area.

The red line across the river represents the place that elevation measurements were taken. Each red thumb tact is placed 100 feet apart from each other. The red number next to the tact is the depth of the land from the staring point, the river walk. The First red point is closest to the starting point, representing 100 feet out, then second point being 200 feet out, and so on.
