Chesapeake Data Explorer

The Chesapeake Data Explorer is a portal to all of the data collected through the Chesapeake Monitoring Cooperative. It is a place for monitoring groups to upload and manage their water quality data and see it alongside all of the other data being collected throughout the Chesapeake Bay watershed.

How to Upload Data

In order to upload data, your group must work with a CMC service provider who will register your group and set up the parameters and stations monitored. Once a group is registered, individuals who will be uploading data must create an account under that group. Registered users can be designated as a coordinator or monitor depending on their data upload needs and QA responsibilities.

Who uses our data?

Data published on the Chesapeake Data Explorer are publicly accessible to anyone who wants to use it via the query function on the homepage. Additionally, the data are used by the Chesapeake Bay Program and state agencies to help assess bay and watershed health.
