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.

Seagrass ecosystem trajectory depends on the relative timescales of T resistance, recovery and disturbance (Page 1)

Seagrass ecosystem trajectory depends on the relative timescales of T resistance, recovery and disturbance

Seagrass ecosystems are inherently dynamic, responding to environmental change across a range of scales. Habitat requirements of seagrass are well defined, but less is known about their ability to resist disturbance. Specific means of recovery after loss are particularly difficult to quantify. Here we assess the resistance and recovery capacity of 12 seagrass genera.

Long-term nutrient reductions lead to the unprecedented recovery of a temperate coastal region

Lefcheck JS, Orth RJ, Dennison WC, Wilcox DJ, Murphy RR, Keisman J, Gurbisz C, Hannam M, Landry JB, Moore KA, Patrick CJ, Testa J, Weller DE, and Batiuk RA ·
2017

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.

5 September 2017

The Department of the Interior Climate Science Centers (CSCs) and their managing organization, the National Climate Change and Wildlife Science Center at the U.S. Geological Survey, have chosen the emerging climate science field of Ecological Drought as a research focus area. This newsletter highlights the outcomes of a two-day workshop held in Honolulu, Hawai'i as part of a series of meetings at each of the nation’s eight CSCs.

21 July 2017

This report card provides a transparent, timely, and geographically detailed assessment of health in Guanabara’s Bay and basin using data from 2013-2015. Guanabara Bay health and Guanabara Bay Basin health are defined as the progress of five water quality indicators toward scientifically-derived thresholds or goals. The indicators are combined into two water quality scores, one score for the Bay, and one for the Basin.
