Geological Collections Loan Policy

Access to information and data pertaining to SIO core and dredge samples can be found in two locations:

Geological Collections Database at Scripps

Index to Marine and Lacustrine Geological Samples

The Geological Collections' sample data files also contain information about SIO expeditions and samples.

SIO Core and Dredge Loan and Sample Distribution Policy

Policy: The collections of marine sediment and dredged rock are made available to researchers and educators to promote better understanding of the geological history of the earth and biological and geological processes in the world ocean. Researchers, educators and students are encouraged to submit requests for samples for scientific research, teaching and/or classroom projects. Material of high scientific interest is reserved for research resulting in published contributions. If you publish on the samples you request from Scripps, please acknowledge us in your publication. Please send us a PDF copy, once available, so we can update our records.

Proprietary Hold: Principal Investigators (PIs) have a 2-year proprietary hold (from date of collection) on any materials collected for their own research. With permission of the PI, certain samples may be released for study prior to the end of that period. Conversely, the hold period may be extended, if the PI is still actively working on the material.

Recipient Responsibility: Researchers must submit at least 1 reprint of any publication or report resulting from study of collections material. Educators and students should submit a brief explanation of how materials were used, and any feedback resulting from the use of materials. Recipients should acknowledge the SIO Geological Collections in publications or public exhibits utilizing Collections material.

Sample Availability: Dredge-haul material, usually collected in large volumes, is the most readily available; educators and students are especially encouraged to utilize these samples. Some additional materials are specifically set aside for educational purposes.

Sediment cores comprise less material and have high stratigraphic value and so require more conservative sampling. Material from the tops of cores is in highest demand, and requests for that material are subject to the most rigorous review. Researchers are asked to request only amounts required to fulfill the objectives of the study.

The Curator or the SIO Curatorial committee must approve all requests for samples.
