         <p>The KNB was launched in 1998 with a grant from the National Science Foundation (NSF), with the purpose of being the long term home for synthesis datasets and research products generated by <a href="https://nceas.ucsb.edu">National Center for Ecological Analysis and Synthesis</a> (NCEAS) working groups. Since then, NCEAS has continued to operate the KNB not only as an archive for NCEAS working group products, but also for the broader ecology and environmental science community. The KNB acceps all environmental or ecological related data and publishes datasets with Digital Object Identifiers for the express purpose of ensuring long-term access to these datasets. We strive to abide by FAIR (findable, accessible, interoperable, resuble) principles of data sharing and preservation.</p>

             <p>
               NCEAS has fostered a global community of ecologists and multidisciplinary environmental scientists eager to solve some of the toughest environmental questions through collaborative, synthesis research, since 1995. NCEAS believes data transparency and reproducibility are essential to the utility of the environmental sciences, and works to advance scientific culture in the direction of open science. The KNB is a primary public data archive for NCEAS working group research products, and hosts data from NCEAS initiatives such as <a href="https://alaskasalmonandpeople.org">the State of Alaska's Salmon and People</a> project and the <a href="https://snappartnership.net/">Science for Nature and People Parnership</a>.

          <h3>Partnered with DataONE</h3>
             <p>
               Data Observation Network for Earth (DataONE) provides a distributed framework and sustainable cyberinfrastructure that meets the needs of science and society for open, persistent, robust, and secure access to well-described and easily discovered Earth observational data. DataONE is a federation of repositories based on a common infrastructure that allows for federated search and replication between repositories. The KNB is a Tier 4 DataONE member node, meaning that it allows the DataONE infrastructure to use available storage space on the KNB for storing copies of objects that originate on other member nodes in the DataONE network, based on the Node Replication Policy. This helps ensure dataset longevity by providing geographically distinct copies of data on multiple servers.
