Many estuaries have been degraded by nitrogen pollution coming from urban and agricultural run-off, which can lead to algal blooms and eutrophication.

As people from many communities return to the revitalized St.

Gated storm surge barriers have been constructed or proposed in many estuaries worldwide for coastal flood risk reduction.

Rising coastal flood risk and recent disasters are driving interest in the construction of gated storm surge barriers worldwide, with current studies recommending barriers for at least 11 estuaries in the United States alone.

The Habitat Heartbeats project is developing a monitoring system to integrate living organisms such as oysters and mussels ("biosentinels”) with existing monitoring efforts.

The Habitat Heartbeats project was featured during the 2023 virtual symposium showcasing recent scientific studies related to the restoration and health of San Diego estuaries including the Tijuana River Estuary, San Diego Bay, and Los Peñasquitos Lagoon.

A project team at the San Francisco Bay NERR is working with various stakeholders to design a road modification project in China Camp State Park. Road modification is necessary for the community to maintain road access to and through the park as sea level rise continues to threaten low-

China Camp State Park is one of the few remaining ecologically intact landscapes of the San Francisco Estuary, but the region is becoming increasingly vulnerable to sea-level rise.
