Research in the catchment has been ongoing since the 1970's. The following are some of the collections for which samples have been analyzed and which may be made available:
Specimens of soils, fractured rock, bedrock, soil porewaters, streamwater, groundwater, rainfall, leaf litter, green leaf samples, woody materials, and tree increment cores have been sampled at SSHCZO. Rock and fractured rock samples are collected from cores extruded during drilling. Porewater samples are drawn from lysimeters, and other water samples are collected using automated samplers. Groundwater samples are collected by hand using a small field pump.Vegetation samples are collected from leaf litter trays, clippings and corings both from the ground in the canopy. The samples are archived after analysis and curated by SSHCZO staff. Regolith and bedrock samples are also available for the satellite sites either through the satellite team institutions or in the PSU archive. Physical samples, including soil, rock, water, vegetation, and drilling samples collected at Shale Hills are routinely registered with SESAR (http://www.geosamples.org), organized and archived (when sample size warrants), and are available upon request for further studies. To date, 2 Cores, 4064 Terrestrial Sections, 462 Other specimens (primarily leaves), 61 Individual Samples, 216 Powders, and 3 Rock Powders have been registered to SESAR on behalf of the CZO. In addition, there are 42 datasets registered and searchable within the EarthChem library.
