Effective coral reef conservation cannot be accomplished without an informed and engaged public. The American Samoa coral status report is part of a larger effort to provide communities and decision-makers with information about managing and conserving coral reef ecosystems. The American Samoa status report presents the results of an analysis of indicators that were chosen to reflect key ecosystem processes and values.

Guanabara Bay, a natural tropical embayment in Southeast Brazil adjacent to Rio de Janeiro, is important to the Brazilian economy as it provides areas for shipping, industry, recreation, and tourism. But commercial and residential urban development in the watershed results in water quality degradation. In Guanabara Bay, strong water quality gradients as a function of inputs and tidal flushing were evident.

Watershed export of fine sediment, organic carbon, and chlorophyll-a to Chesapeake Bay: Spatial and temporal patterns in 1984–2016

Zhang Q, and Blomquist JD ·
2018

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.

Low dissolved oxygen (DO) conditions are a recurring issue in waters of Chesapeake Bay, with detrimental effects on aquatic living resources. The Chesapeake Bay Program partnership has developed criteria guidance supporting the definition of state water quality standards and associated assessment procedures for DO and other parameters, which provides a binary classification of attainment or impairment.

12 November 2018

The Healthy Rivers for All partnership has created a process to develop new collaborations and partnerships in river basins to improve holistic management of water. The approach uses an inclusive process that helps communities create a common understanding of basin health, foster a shared vision for the future, and track progress in achieving goals.
