6 June 2023

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay and its Watershed. Since 2016, UMCES has engaged stakeholders throughout the watershed to transform the report card into an evaluation of the Chesapeake Watershed health. Watershed health includes traditional ecological indicators, but also economic and societal indicators. This is the fourth year the watershed has been scored, and one new ecological indicator has been added.

Global change has converted many structurally complex and ecologically and eco- nomically valuable coastlines to bare substrate. In the structural habitats that remain, climate-tolerant and opportunistic species are increasing in response to environmental extremes and variability. The shifting of dominant foundation species identity with climate change poses a unique conservation challenge because species vary in their responses to environmental stressors and to management.

24 March 2023

The Chesapeake Bay Scientific and Technical Advisory Committee (STAC) and IAN have partnered to synthesize the contents of their latest publication on Rising Watershed and Bay Water Temperatures— Ecological Implications and Management Responses into a report summary outlining key management and research recommendations, the causes and effects of rising water temperatures, and actions for moving forward. This document also builds on the previous STAC Rising Water Temperatures Workshop newsletter.

Synthesizing large, complex data sets to inform resource managers towards effective environmental stewardship is a universal challenge. In Chesapeake Bay, a well-studied and intensively monitored estuary in North America, the challenge of synthesizing data on water quality and land use as factors related to a key habitat, submerged aquatic vegetation, was tackled by a team of scientists and resource managers operating at multiple levels of governance (state, federal).

A water quality barometer for Chesapeake Bay: Assessing spatial and temporal patterns using long-term monitoring data (Page 1)

A water quality barometer for Chesapeake Bay: Assessing spatial and temporal patterns using long-term monitoring data

Zahran AR, Zhang Q, Tango P, Smith EP ·
2022

This paper develops a barometer that indexes water quality in the Chesapeake Bay and summarizes quality over spatial regions and temporal periods. The barometer has a basis in risk assessment and hydrology, and is a function of three different metrics of water quality relative to numerical criteria: relative frequency of criterion attainment; magnitude of deviation from a numerical criterion; and duration of criterion attainment.
