16. DATA AND SAMPLE MORATORIUM
We are the Marine and Geology Repository, a research facility of Oregon State University (OSU-MGR) that supports Earth, Ocean, and Antarctic sciences. In our facility we host geological collections acquired since the 1960's of sediment and rock cores, dredge and ROV samples. We provide advanced instrumentation for analyses of these materials.
These collections are made accessible to the U.S. community and beyond and have grown through the years from major additions and collections of opportunity from research funded through other resources and donated to the repository to support our mission. These programs include Marine Geology and Geophysics and Polar Programs at NSF, NOAA, DOE-NETL, USGS, and DOGAMI. Additionally, we serve OSU and CEOAS researchers as well as the wider research community by providing sample storage and research facilities with the understanding that these materials will be donated to the facility for curation and subsample distribution after a moratorium period.
As stewards of these invaluable collections we curate using best practices and distribute samples upon request to all qualified users for research and/or education. Our goal is to make the collections more accessible and discoverable, both physically and digitally. This document is designed to clarify the policies regarding the diverse activities within our facility and curation of the collections to support the scientific community now and in the future.
Our mission is to facilitate research, education, and the advancement of scientific knowledge through access and preservation of our diverse collection of rock, lake, and marine sediment samples from around the world's oceans, including the Arctic and the Southern Oceans.
The purpose of the repository is to curate our collections and associated datasets in order to facilitate modern science and research. To do this we work to:
Several collections of geological samples from around the world are housed at OSU-MGR. Most collections are made up of samples taken during research cruises. While ocean sediment samples and rocks are a focus of our collections, we also house terrestrial core samples and hand samples from various field campaigns. The five major collections of the OSU-MGR are listed below:
OSU-MGR follows the Oregon State University Code of Ethics.
Acquiring new samples to the collections is central to the role of the OSU-MGR. Potential donations must be evaluated by OSU-MGR staff. If the samples meet the repository's standard criteria, they will be formally accessioned into the OSU-MGR collections. The criteria used in evaluating a potential acquisition include:
6.1 Donor Responsibilities
Donors must fulfill all requirements by providing clear and structured data in relation to the samples submitted to the repository. These obligations provide essential information that allows the facility to adequately provide services and samples for years to come.
At all times the OSU-MGR reserves the right to refuse to acquire any set of samples, if the samples have not been processed accordingly and are incompletely documented. The submitted metadata form must be approved by repository staff before samples can be delivered. Staff may partially approve of a list of samples proposed for accession (e.g. remove duplicates, remove samples because of missing or poor metadata, availability of associated datasets, amount of space per researcher). In addition, rock and sediment samples that are too large or too heavy will be subsampled by the OSU-MGR.
Once approved for accession, the samples will be formally transferred into the OSU-MGR collections. These collections will be curated in perpetuity, and as such will be made findable and accessible per the mission of the repository. OSU will register the samples with the System for Earth Sample Registration (SESAR) in order to acquire an International Geo Sample Number (IGSN, a globally unique and persistent identifier) for each sample.
Deaccession will remove a sample physically from the inventory of the OSU-MGR repository. Following deaccession, samples will be disposed of by appropriate means. Disposal may consist of transfer to a more appropriate repository, removing the sample(s) from the main research collections to outreach collection status, or donation to teaching collections. A record of the deaccession will be made in the database. The criteria used in evaluating a potential deaccession include:
There are three main storage areas within the repository, each with its own set of storage conditions appropriate for preservation of specific sample types. In all cases, the facility includes a backup generator, temperature monitoring, and alarm systems.
Dry/Rock Storage Areas: These areas are subject to ambient storage conditions of the Research Way Building. The temperature is not tightly constrained and will vary with the temperature and humidity conditions of Corvallis, Oregon throughout the year. The rock drill core, rock samples, and dry sediment cores are stored in this area.
Cold Room: This is the storage area for the repository's sediment core collections. The room maintains a temperature of 36-40°F. These conditions are appropriate for the preservation of sediment cores such that they will not freeze nor desiccate, and will slow any growth of mold.
Freezer: This storage area maintains a constant -19°F/-25°C. This storage area is appropriate for samples that must remain frozen, such as permafrost cores.
The OSU-MGR sample request policies and procedures ensure that sample records, data, and publications are all preserved such that the repository will be able to generate access for all collections in perpetuity to serve the research community.
As an NSF/NOAA/OSU funded facility, the OSU-MGR (and therefore PI's who curate their samples) follows Sample and Data Policies. Sample and data requests from our collections are provided to qualified scientific investigators upon receipt of well-documented requests. Materials for educational purposes and museum displays may also be available in limited quantities.
Initial requests should be considered a survey to determine if more samples will be required later. Large requests may require more justification. Subsequent sample requests during the same investigation should include an additional statement describing progress of the study and stating the need for additional material. Student requests should be submitted through their academic advisor.
We require that requestors submit two documents with their sample request:
Cores are split into two identical halves after retrieval, the working half and the archive half. While the working half is available for sampling to facilitate scientific objectives, the archive half is intended to remain as a pristine stratigraphic record of the material recovered. All the non-destructive analyses are usually made on the archive half (e.g. magnetic susceptibility, gamma ray density, line scan images, XRF-scans, CT-scans). Once the working half has been depleted, the archive half may need to be sampled. In these instances, a careful decision will be made by the repository staff to determine if the proposed science and sampling plan justifies sampling of the archive half of the core. In order to preserve the most complete record of the core the OSU-MGR requires that all non-destructive analysis must be completed on the section prior to sampling. Some of this is routine curation practice and has no cost to the person(s) requesting samples, others are not and will incur costs to the person(s) making the request.
This policy is expected to evolve as new techniques develop and become beneficial to the communities who work with OSU-MGR collections.
Sample requests are forwarded to the curators for approval. In cases of conflict of interest,
The staff of the OSU-MGR will take the requested samples, or researchers may take their own samples under staff supervision. We request that researchers with large sample requests (>100) come to the repository to collect their samples.
Samples will be taken so that a continuous vertical portion of the core remains in the work half whenever possible. In general, the archive half is reserved for non-destructive analyses in order to preserve the original stratigraphy of the core. (See "Archive Half Requests".)
The MGR pays for shipping of samples within the United States. International researchers should plan to submit a shipping account number prior to sampling.
Users must be trained for use of OSU-MGR equipment by staff. Additional safety training may be required for use of an instrument via OSU EH&S. Users are required to pay for use of instrumentation and associated technician time per current fee schedules available online at the repository's webpage. Users should let staff know if an instrument is not working properly or data quality is suspect.
The OSU-MGR adheres to the standard NSF Sample and Data Policies.
After a standard (two year) moratorium, all sample materials housed at OSU-MGR and data created at the facility will be made publically available to the Earth science community. Extensions of this moratorium period may be possible and can be requested by Principal Investigators via email to the relevant funding agency (cc'ing OSU-MGR). The sample collectors will have direct and sole access to those samples during a moratorium period.
Members of the advisory board provide input and oversight on policy development and implementation, direction of the repository, as well as general operational feedback. Specifically, the board may also provide guidance in the event of conflicting sample and/or data-related requests, archive half requests, moratorium inquiries, or deaccession efforts.

Outreach is an important part of what we do at the OSU-MGR. Educational visits (including K-12 field trips and OSU undergraduate/graduate labs) may be scheduled by request with the MGR staff subject to availability of the staff and facility. These visits typically include touring the facility as well as viewing representative cores. These representative "tour cores" have been chosen to show a variety of ocean sediments and must remain at the MGR to ensure proper care. The repository has several outreach activities that may be used off-site, either by MGR staff or loaned out upon request for use in classrooms or at public events. Additionally, there are virtual online options on the MGR website that provide videos and core information for use when in-person visits are not possible.
