Here we explore the Critical Zone that encompasses the lowermost groundwater to the atmosphere that meets the earth. Exchanges between rock, water, soil, and living things that are critical to our sustainability. To understand the importance of this zone to us, this blog will focus on Critical Zone processes in Springfield, Ohio, our home.

Phosphate Behavior Comparison
In looking at the
behavior between scales (time/scale) we discovered that the Ohio River averages
over the month of September was [7g/km2/h], unlike that of Buck Creek, which is
less than [1g/km2/h], at (0.62g/km2/h).
By looking at the
comparison of data, Phosphate collected at Buck Creek was collected over a time
period of 1 day. In that 1 day, we took two samples at every 5 spots within our
location in that watershed.
Buck Creek WaterShed
The data of the
Ohio River was over a span of 12 months, with samples being taken on the first
of each month from 1963- 2011 (48 years). When we narrowed that data down, we
chose the month of September. We had data from the 1st of September
for the years of 1963-2011.
So, from both our
own collection of data from Buck Creek, and the data that we found on the Ohio
River we can conclude that the differences in the scales vary due to size/space
and time of the collection period. ( sources for pictures Google maps) By : Shirley and Emilie
