The dynamics of ponds may change drastically on a variety of timescales. The following archived data sets provide examples of pond behavior under different seasonal conditions. The archives also provide an opportunity to explore pond dynamics when our real-time data collection systems are removed for maintenance.

Miscellaneous Data
Download Pond Bathymetry.xlt.
This Excel file contains key physical parameters (e.g. depth and volume) as well as bathymetric information (e.g. volume as a function of depth).
Alkalinity (2001)
Alkalinity (2002)
Download TDIC.xlt, a template to assist in calculating components of the carbonate system and pCO2 from the archived data sets. TDIC.doc explains the calculations behind the template, as well as the significance of the calculations. The template was created in Excel.
K-12 teachers and students:
Download the conversions.xlt template to assist in analyzing archive data sets.
The template was created in Excel.
Laboratory Demonstrations:
There are two guides for laboratory exercises provided on our server. The first (LabDemoNo1.pdf) illustrates the important principle of residence time and the second (LabDemoNo2.pdf) invites exploration of the dynamic equilibrium concept.
