Becoming a new administrator

We welcome input from the scientific community. If you would like to add a new site, program, or network to the P2ERLS system, we encourage you to do so directly, by applying to become an administrator of the P2ERLS database. Here's the process.

First, you'll need to create an account or login. Once you are logged in, you will see a new Become An Administrator link at the top of the page. Click this link and follow the directions on the page that appears. When you apply to become an administrator of the website, you will be asked to agree to the following statement:

"By requesting to become an administrator, I agree to add or modify sites only with the most up-to-date, correct information. Creation of non-existent entities or incorrect modification to existing entities will lead to the removal of my account from the P2ERLS system and any erroneous data that I have submitted."

Once you have filled out and submitted the required information, the website administrator will need to review your submission and decide whether or not to authorize limited administrator privileges. This decision will be based on the accuracy of the information you have provided. Upon approval, an email will be sent to the email address you provided. Please note: the website administrator has the right to deny or revoke administrator privileges at any time.

P2ERLS Data Management Policies
Last update: November 14, 2007

Disclaimer: While substantial efforts are made to ensure the accuracy of data and documentation, complete accuracy of data cannot be guaranteed. All data are made available "as is". P2ERLS and its supporting organizations, including the Jornada Basin LTER, the USDA-ARS Jornada Experimental Range, and New Mexico State University shall not be liable for damages resulting from any use or misinterpretation of data sets.

Quality Assurance Policy: The goal of P2ERLS data management is to build and maintain an archive of data that are fully documented, error free, and organized in useful ways. Data entry programs error-check some data as they are entered. Data are subjected to further verification by examination by P2ERLS website administrators. Routine tape data backups of the file server are done daily, weekly, and monthly. Final quality assurance of the data rests with the person who submits data for inclusion in P2ERLS.

Policy on Submission of data:: Data is only added by authorized administrators. These may include P2ERLS staff, or persons who have submitted an application to become a P2ERLS administrator. All administrators agree to add or modify sites only with the most up-to-date, correct information. Creation of non-existent entities or incorrect modification to existing entities will lead to the removal of the administrator’s account from the P2ERLS system and any erroneous data that was submitted.
