Bay Model

Bay Model Association, as a 501(c)(3) non-profit, creates and supports educational and community programs to encourage the appreciation and stewardship of the San Francisco Bay and Delta ecology.

Our Mission

Bay Model Associations’ mission is to install a passion for life-long learning through examination of our natural world.

EXPLORATION

At BMA, the natural world is our classroom! Educational programs take students outdoors and around the globe on learning adventures.

ENGAGEMENT

BMA’s educational pedagogy is rooted in hands-on, inquiry-driven, project-based learning. Students learn by doing in an interactive environment that stimulates their natural curiosity.

EDUCATION

Learners of all ages participate in BMA’s educational programming. Our project-based approach encourages “student” to share newly acquired knowledge with their greater community.

We are happy to provide the best online platform that helps us reach out to our community members and the world. Explore our portfolio to learn about our plans.

Educational Programs

JASON Project

The JASON Project takes Bay Area students and teachers on virtual scientific expeditions to work with scientists in biomes around the world.

Scientist-At-Sea

Our Scientist-At-Sea program has just begun. Join us as we chronicle Sue Fox's sail across the Pacific. Equipped with satellite technology.

Visitor Center

The Bay Model Visitor Center conducts a rich blend of public education programs that include interactive workshops, programs and events.

Delta Ecosystem Restoration

San Francisco Bay and Delta Ecosystem Restoration

The San Francisco estuary is composed of San Francisco Bay and the Sacramento-San Joaquin Delta. It is the largest estuary on the West Coast. The San Francisco Bay and Delta system support various economic activities, including shipping, sand mining, and recreation. The freshwater that earlier flowed into the delta is used for agriculture and water supplies. This can recently become an issue for the ecosystem due to the alteration in the salinity of the marine water. Other threats to the delta include urbanization and climate change.

Current challenges

The San Francisco Bay and Delta today face many challenges that need to be addressed to restore its ecosystem. Among the biggest challenges that we have are sewage spills and their crumbling infrastructure that is caused unacceptable levels of pollution to the beaches. It has caused destruction to over 90% of shoreline wetlands and also to 40% of the aquatic ecosystem.

Bay

It has led to the protection of more than 90 species and animals in this region.
Occasional drought has also caused problems to the agricultural and economic sector of the delta. Other natural disasters, including earthquakes and floods, have also caused problems in the past, affecting the water supplies to San Diego's homes.

Available solutions

The CMHRP is also involved in the San Francisco estuary projects that included habitat conservation, resilience, restoration, and studying the sea levels. The researchers and scientists at CMHRP study sediment transport, natural process, and human intervention in the estuary to come up with better solutions to improve the health of the ecosystem.

Sediment delivery to marshes

Marshes help maintain the elevation with the rising sea levels by accumulating sediment transported from adjacent waters. Several marsh restoration projects have been successful, but even today, marshes dynamics are poorly understood.

CMHRP is studying the sediment flux in the tidal creeks, wave attenuation, sediment trapping, and suspended sediment properties to better understand marshes. It will help the scientists at CMHRP better understand the health of marshes and the threats of rising sea levels.

Drivers of aquatic habitat

Both state and federal agencies manage the water supply from the San Joaquin Delta. The agencies make sure that the water projects under them are safe to provide water to people while also safeguarding the species. The fisheries have declined in the delta, and some of them have become endangered. There are new projects for the major restoration of endangered and threatened species.

Drivers of aquatic habitat

CMHRP and USGS Water Resources Mission Area are working on learning about the species in the water to gain a better knowledge of their protection. The results of these results will help in better management of the ecosystem. It will accelerate habitat restoration of the bay and delta regions while also providing sufficient water to the nearby regions.
