Abstract

Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean conventional resources of 11.4 billion barrels of oil and 88.2 trillion cubic feet of gas in the Niger Delta Province of Nigeria and Cameroon.

Water in, no water out—How a rain garden reduced stormwater at City Hall in Gary, Indiana

Introduction Urban stormwater runoff can be an issue in many communities because it may cause flooding, overwhelm sewage treatment plants, and negatively affect water quality in local streams, lakes, and other waterbodies. Stormwater runoff can be controlled by using "green infrastructure," which consists of engineered structures that imitate nature to collect stormwater runoff, reduce the amount of runoff, and improve water quality. In 2014, the city of Gary, Indiana implemented green infrastructure to reduce the negative effects of urban stormwater on Lake Michigan and its tributaries. From November 2016 to June 2017, the mostly impermeable parking lot in front of Gary City Hall was removed and rebuilt with a rain garden. The U.S. Geological Survey studied how the rain garden reduced stormwater runoff and published results in Scientific Investigations Report 2022–5101.

Divisions of geologic time—Major chronostratigraphic and geochronologic units

Introduction The reports and maps of our Nation’s geological surveys inform and benefit the public, private industry, government officials, and scientists. The use of clear and consistent nomenclature and classifications can improve communication of data and interpretations. Since 1899, the U.S. Geological Survey (USGS) Geologic Names Committee (GNC) has been responsible for defining standards that promote uniform geologic nomenclature and classifications among geoscientists. The GNC periodically publishes a geologic time scale, the “Divisions of Geologic Time,” that serves as the national standard for USGS publications (for example, refer to Orndorff and others, 2023). Authors may use other published geologic time scales, such as those of the Geological Society of America (GSA) or the International Commission on Stratigraphy (ICS), provided that they are clearly specified and referenced. Access to the USGS, GSA, and ICS geologic time scales is also available from the U.S. Geologic Names Lexicon (Geolex) website https://ngmdb.usgs.gov/Geolex/stratres/timescales. The geologic time scale serves a dual purpose by enabling authors to distinguish earth material units by position (chronostratigraphic) and time (geochronologic), as outlined in order of decreasing rank.
