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.

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.

Ecological Forecasting and the Science of Hypoxia in Chesapeake Bay (Page 1)

Ecological Forecasting and the Science of Hypoxia in Chesapeake Bay

Testa JM, Clark JB, Dennison WC, Donovan EC, Fisher AW, Ni W, Parker M, Scavia D, Spitzer SE, Waldrop AM, Vargas V, And Ziegler G ·
2017

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.

Submersed Aquatic Vegetation in Chesapeake Bay: Sentinel Species in a Changing World

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

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.
