Hello everyone – The attached JPG files show the full year of stream level data for 2009. A few notes:

In order to make nine graphs big enough to be useful, I divided them into four groups. Group one is the rain gauge data, surface temperature and cave air temperature. Groups two, three and four are temp and depth from Thunder River, Carroll River and UL2 respectively.

All of the graphs use the same horizontal scale. If you print them all out and stack them vertically, they will line up.

The flat lines in the middle of the graphs for rainfall and surface temperature represent about 6 months when that data logger was out of service.

The graph for cave air temperature has several spikes in it. These are caused by handling the data logger when it is downloaded. They do not represent real cave temperatures.

If you want the raw data, send me an email. I can provide either .HOBO or comma-separated value files. The HOBO files are what actually comes off the data loggers. You must have a copy of HoboWare Pro to use them, and that is not a free program. CSV files can be used in most spreadsheets and databases.

Bill Gee
