2021 Maryland Coastal Adaptation Report Card

Katie May Laumann, Annie Carew, Heath Kelsey ·
21 January 2022

For the last decade, the State of Maryland has invested in and made progress toward adaptation. Through increased funding, planning, regulatory changes, and restoration, Maryland has become a leader in coastal and climate adaptation. However, there is a need to clarify adaptation goals in order to measure progress and hold the state accountable.

The University of Maryland Center for Environmental Science Integration and Application Network has partnered with Council Fire, LLC, the Clinton River Watershed Council, Friends of the Detroit River, Huron River Watershed Council, River Raisin Watershed Council, and Friends of the Rouge to create socio-environmental report cards for five rivers in southeast Michigan. An overall report card that integrates the results into an assessment of the southeast Michigan region will also be produced.

Nutrient Improvements in Chesapeake Bay: Direct Effect of Load Reductions and Implications for Coastal Management (Page 1)

Nutrient improvements in Chesapeake Bay: Direct effect of load reductions and implications for coastal management

Murphy RR, Keisman J, Harcum J, Karrh RR, Lane M, Perry ES, Zhang Q ·
2022

In Chesapeake Bay in the United States, decades of management efforts have resulted in modest reductions of nutrient loads from the watershed, but the corresponding improvements in estuarine water quality have not consistently followed. Generalize additive models were used to directly link river flows and nutrient loads from the watershed to nutrient trends in the estuary on a station-by-station basis, which allowed for identification of exactly when and where responses are happening.

Nitrogen in the Chesapeake Bay watershed: A century of change, 1950–2050

Nitrogen, a critical element in all forms of life, is continuously being passed from nonliving to living matter and then back again, but an excess of this nutrient can have adverse effects on aquatic environments. An understanding of the past, present, and future sources, movement, and fate of nitrogen in the Chesapeake Bay watershed can help inform efforts to bring this cycle back into balance (fig. OV.1).

2019-2020 Maryland Coastal Bays Report Card (Page 1)

2019-2020 Maryland Coastal Bays Report Card

Alexandra Fries, Nathan Miller, Bill Dennison, Heath Kelsey ·
13 October 2021

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2019-2020 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

Multi-scale trend analysis of water quality using error propagation of generalized additive models

2021

Effective stewardship of ecosystems to sustain current ecological status or mitigate impacts requires nuanced understanding of how conditions have changed over time in response to anthropogenic pressures and natural variability. Detecting and appropriately characterizing changes requires accurate and flexible trend assessment methods that can be readily applied to environmental monitoring datasets. A key requirement is complete propagation of uncertainty through the analysis.
