The LTER Data Portal

The LTER Data Portal offers a coordinated view of LTER data sets and is published by the Environmental Data Initiative (EDI), an environmental data repository that grew out of the information management systems and practices of the LTER Network. Many other environmental science research programs — especially those funded through NSF’s Division of Environmental Biology — also contribute data to the EDI repository.

Data Management As of January 18, 2011, all proposals to NSF must include a supplementary document of no more than two pages labeled “Data Management Plan”. This supplement should describe how the proposal will conform to NSF policy on the dissemination and sharing of research results (see AAG Chapter VI.D.4). The NSF policy includes the sharing of results, primary data, physical samples and collections. This policy also mentions that NSF will enforce this policy through a variety of mechanisms and provide appropriate support and incentives for data cleanup, documentation, dissemination, and storage. NSF suggests that the plan “may” contain: The types of data, samples, physical collections, software, curriculum materials, and other materials to be produced in the course of the project The standards to be used for data and metadata format and content (where existing standards are absent or deemed inadequate, this should be documented along with any proposed solutions or remedies) Policies for access and sharing including provisions for appropriate protection of privacy, confidentiality, security, intellectual property, or other rights or requirements Policies and provisions for re-use, re-distribution, and the production of derivatives Plans for archiving data, samples, and other research products, and for preservation of access to them
Data Policy Long Term Ecological Research Network Data Access Policy The LTER data policy includes three specific sections designed to express shared network policies regarding the release of LTER data products, user registration for accessing data, and the licensing agreements specifying the conditions for data use. LTER Network Data Release Policy Data and information derived from publicly funded research in the U.S. LTER Network, totally or partially from LTER funds from NSF, Institutional Cost-Share, or Partner Agency or Institution where a formal memorandum of understanding with LTER has been established, are made available in a community accepted data repository (e.g., LTER Repository, EDI Repository, Arctic Data Center, BCO-DMO) with as few restrictions as possible, on a nondiscriminatory basis. LTER Network scientists should make every effort to release data in a timely fashion and with attention to accurate and complete metadata. Data There are two data types: Type I – data are to be released to the general public according to the terms of the general data use agreement (see Section 3 below) within 2 years from collection and no later than the publication of the main findings from the dataset and, Type II – data are to be released to restricted audiences according to terms specified by the owners of the data. Type II data are considered to be exceptional and should be rare in occurrence. The justification for exceptions must be well documented and approved by the lead PI and Site Data Manager. Some examples of Type II data restrictions may include: locations of rare or endangered species, data that are covered under prior licensing or copyright (e.g., SPOT satellite data), or covered by the Human Subjects Act. Researchers that make use of Type II Data may be subject to additional restrictions to protect any applicable commercial or confidentiality interests. While the spirit of this document is to promote maximum availability for ecological data in either Type I or II status, there are criteria by which priority for data release may be determined. Primary observations collected for core research activities directly supported by LTER research must receive the highest priority for data release. Data collected by other sources to which LTER supported research has added value is also a high priority Other types of data including non-LTER data that was acquired for LTER research, student thesis data, schoolyard LTER data, or legacy data that already suffer from inadequate documentation or format obsolescence may be ranked a lower priority by a site with justifications provided in their data management policy. Finally, some data may be determined of lowest priority for archiving on the grounds that they are interim data that led to final products that carry the scientific value. These might include data files created during stages within an analytic workflow, raw or replicate data values that were subsequently aggregated or processed for release, or individual outputs from stochastic models. Metadata Metadata documenting archived/online data sets of all types listed above will be made available when, or before, the dataset itself is released according to the terms above. All metadata will be publicly available regardless of any restrictions on access to the data. All metadata will follow LTER recommended standards and will minimally contain adequate information on proper citation, access, contact information, and discovery. Complete information including methods, structure, semantics, and quality control/assurance is expected for most datasets and is strongly encouraged.
Data Sharing Principle Those data are publicly available through the Environmental Data Initiative and searchable on DataONE–and have inspired and launched many major ecological syntheses efforts. In recent years, the Network is focusing additional attention on making LTER Network data fully and easily comparable, via synthesis working groups and efforts such as Community Responses to Resource Experiments (CORRE). Data Use Agreements The ‘Intellectual Rights’ within each metadata document determines the exact data and metadata use agreement between the data user and the LTER site releasing the data. LTER data and metadata may be released under the license: CC BY – Attribution. This license lets others distribute, remix, tweak, and build upon your work (even commercially), as long as you are credited for the original creation. This is the most accommodating of licenses offered, and is recommended for maximum dissemination and use of licensed materials. Alternatively, LTER data and metadata may be released into the public domain: CC0 – No Rights Reserved. CC0 states that data are placed in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright or database law. It is usual practice for major databases to make data freely available under CC0.
