Search Map and View All Search Results

Click Search Map. After a few seconds several blue markers will pop up on the map as shown below. Each blue marker has a number that indicates how many data series exist for that location. The markers cluster dynamically; if you zoom in you will get more precise locations, while if you zoom out the locations will be more generalized. To see all of the data series on the map, click Show Search Results on the right side tool bar as shown below.


Review Data Sets

In the popup window, look for 7 datasets. Review the columns and make sure you have all of the data you will need for the hydrograph separation. You will need delta-18O and delta-D of surface water and precipitation. You will also need stream discharge and incremental precipitation amounts associated with the precipitation isotope samples. A higher resolution time series of precipitation may also be helpful.

Export Selected Data

Highlighting the seven data series from Kent State University, click Select Action and on the dropdown choose Export 7 selections. A zip file should download to your computer. Make sure you know where that file is and that you can access it later.
