This is a three part series on the Asian oyster Environmental Impact Statement. It has been proposed to introduce the Asian oyster (Crassostrea ariakensis) into Chesapeake Bay as one potential solution to the loss of the historic oyster fishery, and the ecological functions that oysters perform for Chesapeake Bay.

To develop the native eastern oyster, Crassostrea virginica, as a biological indicator of nitrogen source, linkages between stable nitrogen isotopes in its tissues and land use adjacent to deployment stations were assessed. As part of a National Estuarine Research Reserve System Graduate Research Fellowship, this study focused on the Monie Bay component of Chesapeake Bay, MD Research Reserve, which includes Monie Bay and three similar tributary creeks which vary in their surrounding land use.

The Republic of Palau, an island nation in the tropical western Pacific Ocean, harbors diverse mangrove, seagrass, and coral communities. Palau is at a crossroads due to improved access to, and development of, its largest island, Babeldaob. This is leading to increased sediment runoff, particularly in the Ngerikiil River/Airai Bay watershed, the most developed region of Babeldaob Island.

This report provides an assessment of eutrophic conditions for 141 U.S. estuaries. The report was based on data and information provided by scientists and experts from around the country. Results from the assessment show that two-thirds of the estuaries evaluated exhibited moderate to high levels of eutrophication. Report production was a collaborative effort between Suzanne Bricker (NOAA NCCOS), EcoCheck (NOAA-UMCES Partnership) and IAN. More information is available from the NEEA website.

This newsletter describes why dissolved oxygen is an important indicator of ecosystem health. It focuses on dissolved oxygen in Chesapeake Bay and its tributaries and describes the factors that affect dissolved oxygen. Additionally, the management decisions and actions that are being taken to reduce the amount of low dissolved oxygen in the Bay are described.

Morro Bay, on the central California coast, was the site of a workshop to develop a conceptual framework for an ecosystem-based management initiative. IAN staff worked with Morro Bay scientists, resource managers, and stakeholders to develop conceptual diagrams for Morro Bay, offshore Estero Bay and the Morro Bay watershed. These diagrams examined key features, threats, and management objectives of the Morro Bay ecosystem.
