We are working with other CZOs to develop cross-CZO capabilities for sharing, integrating, analyzing, and preserving CZO data.
The unique historic Calhoun data are >50-year repeated measurements of old-field soil, plants, and hydrologic responses of experimental catchments that were eroded and gullied prior to reforestation when the land was cultivated for cotton, corn, and wheat.
Some current data projects include:
1) Historic strip chart data is being digitized with help from USGS.
2) NCALM made initial leaf-on LiDAR flights over the Calhoun CZO in late July and early August 2014.
3) A monthly grab sample of seeps, streams, and rivers was initiated in July 2014. Locations were selected from across the CCZO landscape and at different elevations from the 30-plus meter weathering column.
4) 1933 Aerial photo data. High resolution black and white aerial photos have been scanned to be digitized to produce information about land use change, hydrology, energy flux, erosion rates, and biogeochemistry.
