Welcome To DUET

Water quality data submittals, comprised of all field measurement, analytical, and appropriate QC data from all stations sampled, are submitted through the CBP Data Upload and Evaluation Tool (DUET).

DUET performs a series of 170 QAQC checks pertaining to the timeliness, completeness, and quality of the submitted data.

In the spring of 2015, CBP introduced the Chesapeake Environmental Data Repository (CEDR). CEDR is a data enterprise database that currently houses all the CBP water quality and living resources (tidal and nontidal benthic macroinvertebrates, tidal plankton) data holdings since 1984.

All DUET water quality data submittals are imported into CEDR after passing data checks and being accepted by the CBP Data Manager.
