Frequently Asked Questions (FAQ)

The NSF-ICF currently stores over 22,000 meters of firn and ice core collected from various locations in Greenland, Antarctica, and North America. View our INVENTORY for a list of the cores available in the NSF-ICF archive.

Sample requests are coordinated through the Science Management Office. Samples are available to investigators, but NSF-funded investigators may be given priority to certain core sections. Non-U.S. scientists and non-National Science Foundation (NSF) funded scientists may be required to have an NSF funded collaborator before they can be given access to certain ice cores.

Sample requests are coordinated through the Science Management Office. If you have questions, contact Mark Twickler at nsf.icf.smo at unh.edu.

Ice cores obtained through NSF-funded programs may be accepted for storage at the NSF-ICF. Only ice cores made of meteoric ice are authorized for storage at the NSF-ICF. No sea ice, permafrost, or sediment cores are permitted in the facility.

Investigators must contact the Science Management Office (SMO; nsf.icf.smo at unh.edu) during the planning stages of a project, prior to proposal submission, for possible permission to store new ice cores. Investigators must complete the Sample Request/ Facility Use form and email it to the SMO at least four weeks in advance of your proposal submission deadline.

Storage space is an issue, so we are selective regarding which new shallow cores are accepted into storage.

COVID-19 Update

Due to concerns regarding the spread of the Coronavirus Disease 2019 (COVID-19), the NSF-ICF is taking preventive measures and suspending its tour program (including media visits) until further notice. Any groups that have been impacted by the tour shutdown will be prioritized when we resume tour operations. Thank you for your patience and understanding.

The NSF-ICF supports a variety of outreach activities. The facility is a popular destination for field trips from schools, universities, visiting federal agencies, teachers, museum groups, and interested individuals. As such, the NSF-ICF tour schedule generally needs to be booked several months in advance.

Yes, media visits (e.g., film crews) are allowed at the NSF-ICF. However, media visits should be booked as far in advance as possible and a completed 'Media Request Form' must be submitted. NSF-ICF staff cannot accommodate "drop-in" visits or spur-of-the-moment tours. Please plan ahead. For more information, visit https://icecores.org/tours-and-media-visits
