As many as 10 different preparation, cutting, or analysis stations may be set up to accommodate the core with additional processing being performed off the main line if required.

A NSF-ICF staff member measures a section of the WAIS Divide ice core as it begins its journey down a CPL.

In addition, there is also a Class-100 HEPA-filtered, cold clean room held at -24°C that scientists can use.

Scientists often use the exam room to cut samples from the ice cores, and then ship the samples back to their university or laboratory for analysis.

NSF-ICF is funded by the National Science Foundation (NSF) Office of Polar Programs and operated by the U. The National Ice Core Laboratory (NICL) was established in 1993 and renamed in 2018 to the National Science Foundation Ice Core Facility (NSF-ICF).

After racking, the tubes are checked into NSF-ICF's inventory system.NSF-ICF's main archive freezer is 55,000 cubic feet in size and is held at a temperature of -36°C.When a shipment of new ice arrives, the insulated boxes carrying the cores are quickly unloaded into the main archive freezer.Each silver tube on these shelves contains a 1-meter long section of an ice core.The white boxes contain new ice cores drilled from the West Antarctic Ice Sheet (WAIS) Divide ice core site.
