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.

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.

20 September 2018

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2017 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.

This newsletter summarizes the Looking for a Future in Assessment Workshop, held in University College Cork, 27th to 29th March 2018, brought together Regional Seas stakeholders, assessment organizations, and UN and other international bodies. Participants identified a strategic opportunity to work more closely together to chart desired coastal futures.

The world’s waters are threatened by a host of problems. Impacts from human activities like development and overuse are exacerbated by changes in climate, and increased competition by different societal interests, putting vulnerable communities and ecosystems at risk. Creating a sustainable balance of water needs for both nature and people is challenging. It will require people that are competing for water resources to work together in new collaborations and partnerships.

The first Yucatán Coast Report Card was released in April 2018, by the Laboratorio Nacional de Resiliencia Costera (LANRESC), in Sisal, Yucatán Mexico. The report card illustrates the unique connections of groundwater to important coastal resources and values through porous rock and a system of underground waterways. The report card scores indicators for biodiversity, habitat, and water resources.
