Cutting into the subsurface, for example into underground strata, ice, or a tree trunk, to remove material for examination. Intended for broad use wherever coring is done. The combination of this term with other terms will convey the context of the activity.
Shows how coral reef specimens are collected, the type of information gained from them, and the methods by which they are measured and studied to understand recent (past few centuries) changes in climate.
Overview of the Core Research Center (CRC) in Denver for preserving valuable rock cores for permanent storage and making the cores available for examination and testing. Includes links to services, well reports, and resources.
With the South Carolina Department of Health and Environmental Control, USGS is drilling a deep geologic test well to learn about the regional Floridan aquifer, which provides groundwater to the Hilton Head area.
Study of the effects of the practice of cycling municipal nutrient-enriched wastewater from holding ponds through forested wetlands. Studies were in the Cypiere Perdue Swamp, Louisiana, and the Drummond Bog, Wisconsin.
Field trip to Powder River Basin coalbed methane (CBM) development areas showing impacts related to drilling, facilities, pipeline networks, access roads, withdrawal, and disposal of co-produced water from CBM wells.
The U.S. National Ice Core Laboratory (NICL) is a facility in the Denver Federal Center, Colorado, for long-term storage, curating, and studying ice cores recovered from the polar regions of the world with information on public tours.
Program to compile data from the National Water-Quality Assessment Program study units to study national trends with links to sediment coring sites, video on Salt Lake City, study units identification, and publications.
Part A of a complex report on the results of ROCK-EVAL and vitrinite reflectance analysis of a large sample base from more than 70 wells located in three oil-rich California petroleum basins in order to study the formation of oil deposits.
Part B of a complex report on the results of geochemical analysis of 75 shale samples from the Los Angeles, Ventura, and San Joaquin Basins to gather observations relevant to exploration regarding the formation of oil deposits in these basins.
Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
Study addresses questions and concerns related to limited sand resources along the Louisiana shelf and their implications to long-term relative sea-level rise and storm impacts, using newly acquired geophysical and vibracore data.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
