Integrated Trends Analysis Team

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 Kyle Hinson to request that your name and email address be added to the Team's distribution list.

May 2017 Maps of Tidal Trends

Maps of trends in tidal water quality data generated from trend analyses conducted by MD and VA state partners using the General Additive Model method. Annual maps are found below, and further long-term and short-term bottom and surface maps for all parameters can be found on the Integrated Trends Analysis Team ftp site.

Draft GAM Development Documentation

Files located here outline the draft documentation for the GAMs methodology employed by the Integrated Trends Analysis Team. Please email Kyle Hinson (khinson@chesapeakebay.net) with any questions regarding this document and its appendices.

Integrated Trends Projects and the MPA

Additional feedback has been received from the Principal Staff Committee (PSC) and jurisdictions on their priorities to explain water-quality trends for the Mid-Point Assessment (MPA). There will be a discussion regarding how our planned products, which are reflected in the "STAR measuring and explaining water quality trends" project, can address these partner needs as well as an exploration of opportunities to address additional PSC and jurisdiction needs.

Seasonal Kendall & GAM Comparison

This tab provides documentation for efforts to compare methods between the Seasonal Kendall and GAM statistical approaches to determining water quality trends.
