Licensees and Authorized Users that are permitted online access to SEG Library publications may download, save, or print text, search results, or other information from the publications solely for their private use or research. Licensees and Authorized Users may use this online access only in a way that conforms to all applicable laws and regulations.
SEG grants Licensees and Authorized Users permission to use brief quotations from the licensed SEG Library content with the customary acknowledgment of the source, and to copy and transmit content from SEG Library articles, meeting abstracts, chapters, or other content in “person-to-person” and non-systematic scholarly exchanges of information between Authorized Users and specific individuals. See more details at Permissions.
Licensees may not transmit SEG Library electronic article files in digital form to any other institution or to a non-Authorized user. A hard copy printed from the electronic files of the Licensed Material may be supplied to another institution by mail or fax or secure transmission using Arial or its equivalent, whereby the electronic file is deleted immediately after printing, provided the institution is not-for-profit and within the same country as the Licensee. The supply of such copies must conform to CONTU guidelines or similar restrictions to “fair use” provisions under copyright law.
Faculty at Licensee institutions may include articles from Licensed Material in anthologies (coursepacks) in print or digital form for distribution to Authorized Users for use in connection with classroom instruction or in reserves (print or digital) set up by Licensee institutions for access by Authorized Users in connection with specific courses offered by the Licensee. Faculty wishing to use articles (chapters) from SEG eBooks for such purposes must obtain permission in advance by sending a request to [email protected]. Copies of items in digital form that are included in online coursepacks or reserves will be deleted by the Licensee at the end of the semester in which the related course concludes.
The Licensee agrees that use of the Licensed Material by Authorized Users other than indicated above is a violation of the terms of this License.
Prohibitions on Certain Use
The Licensee and Authorized Users shall not knowingly permit anyone other than Authorized Users to use the Licensed Material. Altering, recompiling, reselling, publishing, or republishing (beyond brief quotations with customary acknowledgment of the source) of any journal article, expanded abstract, proceedings, or book text, search result, or other information from the Licensed Material or the SEG Library, or any portion thereof, in any form or medium, is prohibited. Systematic or programmatic downloading, printing, transmitting, or copying of the Licensed Material is prohibited. “Systematic or programmatic” means downloading, printing, transmitting, or copying activity of which the intent or the effect is to capture, reproduce, or transfer the entire output of a journal volume, a journal issue, or a journal topical section, or sequential or cumulative search results, or collections of abstracts, articles, or tables of contents; or to capture, reproduce, or transfer an entire e-book or substantial portions thereof. Other such systematic or programmatic use of the Licensed Material that interferes with the access of Authorized Users or that may affect the performance of SEG’s online systems, for example, the use of “robots” to index content, or downloading or attempting to download large amounts of material in a short period of time, is prohibited. Redistribution of the Licensed Material, except as permitted under Permitted Use, without permission of SEG and/or payment of a royalty to SEG or to the appropriate Reproduction Rights Organization, is prohibited. All rights not expressly granted herein are reserved to SEG or associated societies and related organizations that own content within the SEG Library as indicated. The Licensee and Authorized Users may not circumvent the access-control systems of SEG or associated societies or related organizations or use these systems or services to attempt to gain unauthorized access to any other system or network. SEG shall not be required to distribute, and the Licensee shall not redistribute, the Licensed Material or any article therein to a country to which export is prohibited by U.S. law or regulation.
The Licensed Material and their contents, including abstracts, are copyrighted by the SEG except as may be otherwise noted within the Licensed Material. This material is subject to all applicable copyright, database protection, attribution, and other rights of SEG and other publishers of the Licensed Material under the laws of the United States and other countries. Copyright notices in the Licensed Material and its articles may not be removed, obscured, or modified in any way. Unauthorized copying or redistribution of any content licensed herein is a violation of copyright laws.
Disclaimer of Warranties; Limitation of Liability
SEG warrants that it is entitled to grant the licenses granted in this License. EXCEPT AS SET FORTH IN THE PRECEDING SENTENCE, SEG MAKES NO WARRANTY OR REPRESENTATION OF ANY KIND, EXPRESS OR IMPLIED, WITH RESPECT TO THE LICENSED MATERIAL, INCLUDING ITS QUALITY, ORIGINALITY, SUITABILITY, SEARCHABILITY, OPERATION, PERFORMANCE, COMPLIANCE WITH ANY COMPUTATIONAL PROCESS, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE.
SEG SHALL NOT BE LIABLE FOR: EXEMPLARY, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR OTHER DAMAGES ARISING OUT OF OR IN CONNECTION WITH THE SUBSCRIPTION OR LICENSES GRANTED HEREUNDER, THE USE OR INABILITY TO USE ANY ONLINE PUBLICATION, SEG’S PERFORMANCE UNDER THIS AGREEMENT, TERMINATION OF THIS AGREEMENT BY SEG OR THE LOSS OF DATA, BUSINESS, OR GOODWILL, EVEN IF SEG IS ADVISED OR AWARE OF THE POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE TOTAL AGGREGATE LIABILITY OF SEG AND/OR THE ASSOCIATED SOCIETIES AND RELATED ORGANIZATIONS ALSO SUPPLYING LICENSED MATERIAL, FOR ANY CLAIMS, LOSSES, OR DAMAGES ARISING OUT OF ANY BREACH OR TERMINATION OF THIS AGREEMENT EXCEED THE TOTAL AMOUNT PAID BY THE LICENSEE OR AUTHORIZED USER TO SEG FOR THE ONLINE PUBLICATION SUBSCRIPTION FOR THE CURRENT SUBSCRIPTION YEAR IN WHICH SUCH CLAIM, LOSS, OR DAMAGE OCCURRED, WHETHER IN CONTRACT, TORT, OR OTHERWISE, INCLUDING WITHOUT LIMITATION DUE TO NEGLIGENCE. The foregoing limitation of liability and exclusion of certain damages shall apply regardless of the success or effectiveness of other remedies. No claim may be made against SEG unless suit is filed thereon within one (1) year after the event giving rise to the claim.
Licensees assume sole responsibility for all use of the Licensed Material by their Authorized Users. Other Authorized Users assume sole responsibility for all of their own use of the Licensed Material.
The SEG Wiki content is collaboratively developed by SEG Members using MediaWiki software. Only SEG Members who are signed in may contribute to its content. However, the content of the SEG Wiki, except as may be noted otherwise within it, is available to the public without access controls and is available for reuse by anyone under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC-BY-SA).
This means the content can be copied, modified, and redistributed, including for commercial use, as long as the new version grants the same freedoms to others and acknowledges the authors of SEG Wiki entries (a link to the entry satisfies author-credit requirements). By adopting this copyleft policy for the SEG Wiki, SEG aims to foster growth of this technical information exchange mechanism designed to accelerate the pace of innovation in applied geophysics and related fields.
The SEG Wiki includes the contents of the Encyclopedic Dictionary of Applied Geophysics, fourth edition, by Robert E. Sheriff, and while retaining copyright to this work, SEG licenses it under the CC-BY-SA license except for portions credited to non-SEG sources. Those seeking to reuse these portions must contact the copyright holder for permission. SEG and the SEG Wiki’s editors and contributors own copyright (automatically with respect to editor and contributor contributions under the Berne Convention) to most of the wiki’s content.
By submitting content to the SEG Wiki, contributors agree to license their submissions to SEG and the public under the CC-BY-SA license and other terms specified by SEG. Please see the CC-BY-SA license deed (http://creativecommons.org/licenses/by-sa/3.0/) and the Legal Code that it summarizes (http://creativecommons.org/licenses/by-sa/3.0/legalcode). Wikipedia also uses this license, enabling exchange between Wikipedia and the SEG Wiki provided that license requirements are followed.
In order to contribute to the SEG Wiki, you must be in a position to grant this license. This means
- you own copyright in the material, for instance because you produced it yourself, or
- you acquired the material from a source that allows licensing under CC-BY-SA
Additionally, you may submit material to the SEG Wiki if
- your use of works copyrighted by others adheres to legal standards for fair use, or
- the material is in the public domain (i.e., not owned by any entity)
Regarding material you own: You retain copyright to your materials. You can later republish and relicense them in any way you like. However, you cannot retract the CC-BY-SA license for versions placed in the SEG Wiki.
Regarding material from a source that licenses it under CC-BY-SA: It is required that you acknowledge the authorship and provide a link to the original copy if it is available online. (For example, if a Wikipedia entry is reused in an SEG Wiki entry, a link to the Wikipedia entry is required along with acknowledgment that it is released under the CC-BY-SA license, and the contributors must be acknowledged.) Do not link to a site that violates copyright by distributing someone else’s work without license. If you obtain permission to use a copyrighted work under CC-BY-SA directly from the copyright holder, you must make note of that fact and provide within your SEG Wiki entry the name of the copyright holder and the date permission was obtained.
Regarding material used under fair use: You are required to cite the source and are encouraged to link to an official version if feasible in the context of your contribution.
Contributors of content to the SEG Wiki warrant to the Society of Exploration Geophysicists, its heirs, successors, and assigns, that
- they are authorized to license the work they submit and that they have secured necessary permissions and/or licenses and have provided appropriate and required attribution if contributing work of others.
- they agree to and have adhered to all terms of Ethical Guidelines for SEG Publications that reasonably could apply to the SEG Wiki.
These SEG-specific terms strengthen ethical and legal requirements for content submission. Contributors who are unwilling or unable to abide by terms of the CC-BY-SA license and the SEG-specific terms should not contribute material to the SEG Wiki.
Linking to SEG Materials
SEG strongly encourages SEG Wiki contributors to provide links to official versions of SEG publications, professional development offerings, and other materials. Linking to the official SEG source and acknowledgment of SEG copyright is required if an image or other media file from an SEG source is included in an SEG Wiki entry. Placing the contents of SEG-copyrighted material in the SEG Wiki is not permitted, even if you are the author, without permission in writing from SEG, except as may be allowed under SEG permissions policy. SEG does not offer CC-BY-SA license to its copyrighted material except for the Encyclopedic Dictionary of Applied Geophysics, fourth edition. Your work published in non-SEG publications may carry restrictions on reuse similar to those SEG imposes with respect to its own publications; please check with the publisher and/or copyright owner if you are not certain.
Images and Other Media
It is preferred that images and other media used in SEG Wiki entries be licensed under CC-BY-SA or a similar or compatible “free” license. Other images and media files may be used only under fair-use provisions of copyright law. Because some images and other media used in the SEG Wiki might fit in this category, image-description pages must contain information indicating their legal status. Images and other media without such information in description pages will be deleted. Anyone wishing to reuse images and other media appearing in the SEG Wiki is advised to examine the legal status of these elements and seek permissions as may be required by the copyright holder.
Violators of submissions requirements will be appropriately warned, and submissions in violation of licenses and policies here identified and described will be removed. Repeat violators will be blocked from contributing to the SEG Wiki.
If you detect possible copyright infringement in the SEG Wiki, please make note of it in the potentially problematic page’s discussion page. It is possible that material published elsewhere may legally be posted to the SEG Wiki, and a discussion could shed light on the reality. If you think the situation requires more direct intervention from SEG, please do not hesitate to contact SEG Wiki administrators.

In most respects, the SEG Wiki follows an approach to copyright, licensing, and content reuse embraced by Wikipedia. Wikipedia has several helpful pages on navigating the “free” intellectual property landscape in a wiki environment. SEG encourages SEG Wiki users in need of further guidance to avail themselves of these resources and others offered by Creative Commons.
