The response of estuarine ecosystems to long-term changes in external forcing is strongly mediated by interactions between the biogeochemical cycling of carbon, oxygen, and inorganic nutrients. Although long-term changes in estuaries are often assessed at the annual scale, phytoplankton biomass, dissolved oxygen concentrations, and biogeochemical rate processes have strong seasonal cycles at temperate latitudes.

Fort Monroe National Monument is located at the tip of the Virginia Peninsula in Hampton, Virginia. The site includes the largest stone fort built in the United States and was formally added to the National Park System in 2011, recognizing millennia of human interactions with this landscape. Natural resources within the 325-acre park boundary include an ecologically diverse and productive saltmarsh cordgrass wetlands within Mill Creek.

Chesapeake Monitoring Cooperative's Data Interpretation and Synthesis Methods Manual is a step by step comprehensive guide to interpreting and communicating data for beginner and experienced monitoring groups alike. This manual was produced to be used in tandem with a hands on workshop that guides attendees through the process of interpreting their data.

IAN staff reflected back on accomplishments from 2016 in its 2nd annual report card. The self-assessment is based on indicators in three categories: social impacts, ecological outcomes, and partner engagement. IAN received an overall grade of A- (90%) which is up from 2015's grade of B+ (88%).

Chesapeake Bay has long experienced nutrient enrichment and water clarity deterioration. This study provides new quantification of loads and yields for sediment (fine and coarse grained), organic carbon (total, dissolved, and particulate), and chlorophyll-a from the monitored nontidal Chesapeake Bay watershed (MNTCBW), all of which are expected to drive estuarine water clarity.

This poster describes an indicator matrix developed by the Chesapeake Monitoring Cooperative. The matrix demonstrates the overlapping objectives between the Chesapeake Bay Program’s Management Strategies and volunteer monitoring groups. The matrix can enhance understanding and inspire more monitoring, which will be used for restoration across all Bay Program goals (i.e., clean water, abundant life, conserved lands, and engaged communities).

Derived from river monitoring data, concentration-discharge (C-Q) relationships are useful indicators of riverine export dynamics. A top-down synthesis of C-Q patterns was conducted for suspended sediment (SS), total phos- phorus (TP), and total nitrogen (TN) for nine major tributaries (15 monitoring sites) to Chesapeake Bay, which represent diverse characteristics in terms of land use, physiography, and hydrological settings.

Humans strongly impact the dynamics of coastal systems, yet surprisingly few studies mechanistically link management of anthropogenic stressors and successful restoration of nearshore habitats over large spatial and temporal scales. Such examples are sorely needed to ensure the success of ecosystem restoration efforts worldwide.

Chronic seasonal low oxygen condition (hypoxia) occurs in the deep waters of Chesapeake Bay as a result of eutrophication-induced phytoplankton blooms and their subsequent decomposition. Summertime hypoxia has been observed in Chesapeake Bay for over 80 years, with scientific attention and understanding increasing substantially during the past several decades after rigorous and routine monitoring programs were put in place.

Chesapeake Bay has undergone profound changes since European settlement. Increases in human and livestock populations, associated changes in land use, increases in nutrient loadings, shoreline armoring, and depletion of fish stocks have altered the important habitats within the Bay. Submersed aquatic vegetation (SAV) is a critical foundational habitat and provides numerous benefits and services to society.
