Policies & Funding

The Lamont-Doherty Core Repository serves the national and international ocean research and teaching communities and receives funding from both the National Science Foundation and Lamont-Doherty Earth Observatory. Our primary function is to provide for long-term storage and curation of geological materials. In addition, samples from cores and dredges, descriptions of cores and dredges, digital images and other cruise information from the collection at L-DEO are provided to scientific investigators upon receipt of requests. Materials for educational purposes and museum displays may also be made available in limited quantities where requests are adequately justified. Finally, we also provide analytical services that we charge at cost. 

The Core Repository will accept cores collected by any scientist or ship assuming they are in good condition, have suitable metadata, and will be made available for scientific use. The Core Repository policies regarding PI and public access to cores and data are consistent with the NSF Earth Sciences Division data policy statement and the Ocean Sciences Division data and sample policy. Original PIs, their post-docs, and their students have an “exclusive-use period” of two years from the date of sample collection. Data generated from these cores are also subject to the same two-year period of exclusive use. “Active Phase” is used to denote NSF’s exclusive-use period, and “Archive Phase” refers to the period of time following the conclusion of the Active Phase. The Repository works closely with PIs to protect their intellectual and scientific interests in their own cores, as well as in archived cores, working within NSF guidelines. Once cores enter the Archive Phase, sample requests will be allowed (subject to the standard review process) and basic data, including the core descriptions, core images, geophysical logging data and accompanying metadata, will be made public.

All users of material or data from the Lamont-Doherty Core Repository are expected to acknowledge the facility in their publications and presentations. In addition, we request that all users provide us with an electronic copy of any resulting publications. Citing NSF-funded community facilities in your acknowledgments helps to spread the word about the importance of our mission to the larger scientific community and the general public and helps justify our support by NSF.
