1. How can I contribute content to Tethys?
Tethys has an active content team that is regularly adding new materials, but we appreciate feedback from the community. If you are aware of any missing documents, events, news highlights, job postings, or other information which belongs on Tethys or the Tethys Blast, email tethys@pnnl.gov.
2. Why is Tethys so important for marine and wind energy?
Tethys allows users to search for and access valuable information related to the environmental effects of wind energy and marine energy (e.g., wave, tidal). Marine energy is a relatively new source of energy, so there is still a lack of information and understanding on how to best proceed in developing these technologies in an environmentally responsible manner. Wind energy is fairly well established, but researchers are continually improving on methods of prevention, detection, and assessment. The goal of Tethys is to gather all the relevant information and data on these renewables with the intent to expedite technological development and attempt to clarify the associated uncertainties.
3. What type of content is available in Tethys Engineering?
Documents (journal articles, technical reports, etc.) are the main content in Tethys. These are hand-collected and tagged by our active content team to get you the latest available information. You can search and filter these documents on the Knowledge Base. Tethys also has industry events listed on the Events Calendar and detailed descriptions of environmental monitoring at marine energy deployments and offshore wind farms. Tethys also hosts many other tools and resources to help you better understand the environmental effects of wind and marine energy, so start exploring now!
4. Where does Tethys content come from?
Tethys content is constantly growing, actively curated by researchers at the Pacific Northwest National Laboratory. Documents are collected by subscribing for journal alerts, networking with professionals, scanning other related databases, mining citations in key reports, and by receiving suggestions from the Tethys community. Please contribute by emailing tethys@pnnl.gov.
5. How do I know the material on Tethys is accurate or complete?
Significant effort is placed on ensuring that new content is captured in the database, that documents are tagged correctly, that links function properly, and that any content that may become outdated specifies when the information was collected (regulatory information, metadata forms). However, your help in identifying errors is greatly appreciated - please contact us if you have any corrections or suggestions.
6. Why should I register on Tethys? Can't I already access all the content?
While all content is available on the Knowledge Base, registration on Tethys provides access to a number of personalization and interaction features (learn how to register here). Currently, registered users can:
- Access contact information for members of the Tethys community and be personally included in these contact lists
- Save preferences for entry on the Knowledge Base and Map Viewer
- Associate your account with an author profile so that your information appears along your list of documents
7. If I register, what happens to my personal information?
All personal information collected during registration is used solely for administrative purposes. Your information will not be shared with any third parties.
8. How can I change personal information on my user account?
Simply visit your account page to update your registration information, typically accessed in the upper right of the screen after logging in.
9. What are OES-Environmental and WREN, and how are they related to Tethys?
OES-Environmental (the task formerly known as Annex IV) is an international collaboration amongst member nations of the IEA Ocean Energy Systems to gather information on environmental research related to marine energy. WREN is a separate international collaboration amongst member nations of the IEA Wind to address environmental issues associated with commercial development of land-based and offshore wind energy projects. Tethys is supporting both initiatives by facilitating various outreach activities and events. Tethys also helps OES-Environmental and WREN host marine energy and offshore wind energy project metadata and disseminate this information to a broad international audience.
10. How frequently are Marine Energy Metadata and Offshore Wind Metadata updated?
Project sites and research studies are frequently changing, so we do our best to keep information up to date. One year after the most recent form submission, we try to make contact with the developer/researcher to receive updates with a goal that no metadata forms are more than 18 months old. Each Tethys page will indicate when the form was last updated, shown in the upper right.
11. Why does the Map Viewer have less content than the Knowledge Base?
The Map Viewer only has geotagged content available while the Knowledge Base contains all content on Tethys. All OES-Environmental Project Sites and Offshore Wind Metadata projects are geotagged; some documents and OES-Environmental Research Studies are geotagged, as long as the content references a specific location.
12. What is a stressor and receptor?
Many Tethys materials discuss environmental effects in terms of stressors and receptors. Stressors are the parts of a device or a result of a device's functioning that may cause harm or stress to a marine animal, habitat, or ecosystem process. Receptors are the marine animals, habitats, and ecosystems processes that may be affected by stressors. For example, noise (the stressor) from a tidal turbine may affect a marine mammal (the receptor) by limiting its ability to communicate with others and navigate its environment. If you are confused about any terminology on Tethys, please visit the Glossary.
13. Are there other sites similar to Tethys that you could direct me to?
When it comes to environmental effects information and data on marine or wind energy, Tethys really is one of a kind. However, we have compiled a list of other significant databases with relevance, found here.
14. Are the documents on Tethys all peer-reviewed?
No, Tethys contains a combination of both peer-reviewed and grey literature. Documents can always be sorted by content type, which gives some indication of peer-reviewed status (e.g., journal articles are often peer-reviewed while reports are often not formally peer-reviewed). However, many reports have undergone extensive reviews and are very reliable sources. Those using Tethys should always be aware of the document source and use discretion as to the quality of the information.
15. How do you keyword search on Tethys?
Many of the tables and tools on Tethys have search bars that will narrow results, typically requiring that all keywords entered match the title, abstract, or authors. Because the search only returns when all keywords are found, it is recommended that you limit keyword searches to a few words. Keyword searches can be used in conjunction with filters.
In addition to the search functionality described above, the Knowledge Base, Map Viewer, and site-wide search have special search functionality to accomplish more advanced searches. You may begin a search with "org:" to return results from a specific organization (see example for Marine Scotland Science). Likewise, beginning a search with "author:" with return results from a specific author (see example for Copping). Lastly, you may wrap a specific phrase in quotes to search for exact matches (see with and without quotes). The Knowledge Base sort depends on which column header is selected, while the site-wide search is sorted by relevance where matches in the title are prioritized.
The following targeted searches are available:
- org: author affiliation or sponsoring organization
- author: targets any authors
- journal: targets a specific journal article
- publisher: targets a specific publisher
- location: country or U.S. state where the research was conducted
This example shows a complex search involving a phrase, keyword, and targeted author search.
16. Can I import individual documents or filtered results from Tethys for a literature review?
You can import directly into most bibliographic management tools (Zotero, Endnote, etc.) by downloading an RIS file from Tethys and importing it into your bibliographic tool. There are some browser add-ons to make this really seamless. You can download individual documents as RIS with the "Download Citation File" link on each document page, or you can download filtered results from the Citations Export page.
