Northgrippian
Sign in to saveAlso known as Middle Holocene, Northgrippian Age, Northgrippian Stage
In the geologic time scale, the Northgrippian is the middle of three ages or stages of the Holocene Epoch or Series. It was officially ratified by the International Commission on Stratigraphy in June 2018, along with the earlier Greenlandian and later Meghalayan ages/stages. The age takes its name from the North Greenland Ice Core Project (NorthGRIP). The age began 8,276 BP (6326 BCE or 3854 HE), near the 8.2-kiloyear event, and goes up to the start of the Meghalayan, which began 4,200 BP (2250 BCE or 7750 HE), near the 4.2-kiloyear event.

== Stratotype == The Global Boundary Stratotype Section and Point (GSSP) defining the base of the Northgrippian is an ice core collected by the North Greenland Ice Core Project (NorthGRIP or NGRIP), from a drill site near central Greenland, located at coordinates 75°06′N, 42°19′W. The GSSP, from drill hole NGRIP1, represents the one-time temperature drop recorded during the 8.2 kiloyear event.
