USGS Core Research Center (CRC) Collection of Cuttings

The Core Research Center (CRC) was established in 1974 by the U.S. Geological Survey (USGS) to preserve valuable rock cores for use by scientists and educators from government, industry, and academia. The cylindrical sections of rock are permanently stored and available for examination and testing at the core storage and research facility in Denver, Colorado. The CRC is currently one of the largest and most heavily used public core repositories in the United States. The CRC encourages use of its facility by all interested parties. Tours of the facility are available by appointment.

Peat collapse and vegetation shift at Hickory Point

This work captures a multi-year progression from 2013 to 2021 of change in the height of the topographic surface and freshwater status of the rooting zone that may indicate impending vegetation transition. Two Surface Elevation Tables (SETs) in a tidal Taxodium distichum swamp at Hickory Point State Forest near Pocomoke City, Maryland were used to collect data on the height of the topographic surface established with respect to a local vertical datum. Annual root production over time was measured by collecting data on ingrowth into mesh root bags. Root bags were collected at 5 set locations within the study area and analyzed to determine the weight in grams of new root production per meter cubed each year. This...
