GREETINGS and welcome to the first In Depth newsletter published by the National Ice Core Laboratory - Science Management Office (NICL-SMO). The purpose of In Depth is to keep the ice core community informed about activities, policies, and projects that effect those involved in ice core research; those who use ice core data; and those who have interest in the science resulting from ice coring and it’s data analysis. This inaugural issue is designed to give background information on the National Ice Core Laboratory, Ice Core Data Archive, the Ice Core Working Group, and other items. Future issues will be comprised of updates and descriptions about various projects underway. We are looking for short articles from the community for publishing In Depth. Please contact us if you would like to contribute an article.
