Scope and Purpose

The Integrated Trends Analysis Team aims to combine the efforts of the Chesapeake Bay Program analysts with those of investigators in governmental, academic, and non-profit organizations to identify potential research synergies and collaborations that will enhance our understanding of spatial and temporal patterns in water quality.

Specific Goals:

(1) Gather researchers and analysts from various governmental, academic, non-profit, and private organizations for biannual meetings to identify the broad scope of on-going work related to trends and patterns of water quality in the Chesapeake watershed and estuary.

(2) Discover previously un-identified linkages among the ongoing research activities of participating individuals and organizations.

(3) Develop a standard set of analysis tools that can be applied in any relevant ecosystem within the Chesapeake watershed and estuary.

(4) Foster increased collaboration and awareness of ongoing research.

(5) Provide a forum for bringing findings to the broader Chesapeake Bay management community.

Membership in the Integrated Trends Analysis Team is currently not formally defined. If you would like to receive invitations to upcoming meetings, contact Alexander Gunnerson (agunnerson@chesapeakebay.net) to request that your name and email address be added to the Team's distribution list.

Projects and Resources

Tributary Summaries

The Chesapeake Bay Program and its partners produce tributary basin summary reports for the Bay’s 12 major tributaries using tidal monitoring data from more than 130 monitoring stations throughout the mainstem and tidal portions of the Bay. These reports use water quality sample data to summarize 1) How tidal water quality (TN, TP, DO, Chlorophyll a, Secchi Depth) has changed over time, 2) How and which factors may influence water quality change over time, and 3) Recent research connecting observed changes in aquatic conditions to its drivers.

These documents can be found on the CAST webpage here. 

Maps of 2020 Tidal Water Quality Change

1. Long-Term Change

Observed change in water quality by station from the beginning of the period to 2020.

2. Long-Term Flow-Adjusted Change

Change in water quality by station computed under the condition of average freshwater flow into the Chesapeake Bay over the long-term.  This approach answers the question: “What would the change in water quality have been if flow had been average?”

3. Short-Term Change

Observed change in water quality by station over the last 10 years.

4. Short-Term Flow-Adjusted Change

Observed change in water quality computed under the condition of average freshwater flow into the Chesapeake Bay over the last 10 years.
