Online Data

Environmental Data Entry and Reporting System (eDERS)

(link requires accepting web certificate security exception)

MPSL-MLML puts control back in the hands of users with a state-of-the art online data management system.  The link will require users to accept the typical web certificate security exception.

Key features of the system include:

  • Enables users to manage their data securely and efficiently across the internet on their schedule
  • Enables users to control granular access to their data, defining their unique level of data privacy
  • Enables users to add new data types while maintaining direct export to data repositories like CEDEN and EPA’s WQX

If you currently have data within the MPSL-MLML Data Center database and would like to use the online data management system, please contact Stacey Swenson for login information.  If you would like to manage your data within eDERS or if you have general data management questions, please contact Marco Sigala.

Central Coast Ambient Monitoring Program (CCAMP) Data Navigator

The CCAMP Data Navigator allows you to view Central Coast water quality data in a number of ways, and includes graphs, maps, tables, and statistical tools. The data is sourced from the California Environmental Data Exchange Network (CEDEN) and includes data categories such as basic water quality, nutrients, metals, organics, toxicity, habitat, and bioassessment from water and sediment matrices. Please contact with any questions.


The MPSL-MLML Data Center is responsible for exporting data to the California Environmental Data Exchange Network (CEDEN).  Data will be checked for comparability and will be submitted to CEDEN unless a dataset was registered as private and should be retained in the MPSL-MLML database until further notice.  Common reasons why a data generator would want to retain the data in the MPSL-MLML database rather than exporting to CEDEN include final reports or manuscripts for publication using the data have not been completed or submitted.
