Nutrient- and Climate-Induced Shifts in the Phenology of Linked Biogeochemical Cycles in a Temperate Estuary (Page 1)

Nutrient- and Climate-Induced Shifts in the Phenology of Linked Biogeochemical Cycles in a Temperate Estuary

Testa JM, Murphy RR, Brady DC and Kemp WM ·
2018

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 Historical Park Natural Resource Condition Assessment

Lookingbill T, Engelhardt K, Geraghty C, Hatchel N, Kitchen D ·
15 March 2018

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.

Synthesis of nutrient and sediment export patterns in the Chesapeake Bay watershed: Complex and non-stationary concentration-discharge relationships (Page 1)

Synthesis of nutrient and sediment export patterns in the Chesapeake Bay watershed: Complex and non-stationary concentration-discharge relationships

Zhang Q ·
2018

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.

Evaluation of statistical methods for quantifying fractal scaling in water-quality time series with irregular sampling (Page 1)

Evaluation of statistical methods for quantifying fractal scaling in water-quality time series with irregular sampling

Zhang Q, Harman CJ, and Kirchner JW ·
2018

River water-quality time series often exhibit fractal scaling, which here refers to autocorrelation that decays as a power law over some range of scales. Fractal scaling presents challenges to the identification of deterministic trends because (1) fractal scaling has the potential to lead to false inference about the statistical significance of trends and (2) the abundance of irregularly spaced data in water-quality monitoring networks complicates efforts to quantify fractal scaling.

Tennessee River Basin Report Card Methods Document

Heath Kelsey, Dylan Taillie, Emily Nastase, Bill Dennison, Andrew Elmore ·
9 February 2018

The Tennessee River Basin Report Card was developed as a tool for prioritization and restoration decisions made in the Tennessee River Basin. The report card document is also meant to serve as an outreach tool for use by managers to highlight particular issues of importance when communicating conservation and restoration with the public. This methods document discusses how the report card was developed and how the grades were calculated.

1 February 2018

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%).

2016 Maryland Coastal Bays Report Card

Alexandra Fries, Heath Kelsey, Bill Dennison ·
12 December 2017

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2016 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.

Tuul River Basin Report Card Stakeholder Workshop Summary (Page 1)

Tuul River Basin Report Card Stakeholder Workshop Summary

Simon Costanzo, Dylan Taillie ·
12 December 2017

Participants from various government, private and non-governmental organizations converged on Ulaanbaatar for the three day report card workshop in mid-October 2017. Participants were identified by the Tuul River Basin Authority and WWF-Mongolia to represent key stakeholder groups that have interests in the Tuul River Basin, and help shape the report card development. The workshop had a huge turn out and indicators to assess the health of the basin were identified.
