Welcome to the Northern California Coast, home to some of the world’s Use this guide to: richest temperate marine ecosystems. In this exhibit, students can learn » Plan your field trip to about the coastal ecosystems of the Northern California Coast on both the California Academy of Sciences’ Northern Level 1 and the Lower Level. California Coast exhibit. Upstairs on Level 1, students can follow a walkway along a transect of » Learn about exhibit themes, key concepts the coast from the San Francisco Bay estuary to the rocky coastline. and behind–the–scenes Downstairs on the Lower Level, students will have several underwater information to enhance views into the rocky coast tank, modeled on the habitats of the Gulf of and guide your students’ experience. the Farallones National Marine Sanctuary, including a dramatic floor–to– » Link to exhibit–related ceiling window. Students will walk through a gallery of medium–size and activities you can smaller tanks displaying characteristic habitats of the California coast, download. including rocky coast, rocky reef and sandy bottom. » Connect your field trip to the classroom. Through interactive stations, students can learn more about the Gulf of the Farallones National Marine Sanctuary and California marine life. Students can also interact with docents and use magnifiers to explore a variety of marine organisms at the Tidepool. Understanding the variety of animals and habitats on our California coast, our coastal resources, and how marine sanctuaries can play a role in protecting those resources sets the stage for fostering conservation awareness and environmental stewardship. Students will encounter two major themes throughout the exhibit: » California coastal habitats » Conservation efforts 02 Northern California Coast Educator Guide California Academy of Sciences a Observation Living Roof deck Planetarium exit b Upper Gallery Classroom c Naturalist B.Level exhibit 3 map Center California Academy of Sciences Map d Forum Level 2 Sta Entrance Northern g j Swamp Early California Explorers Cove Coast Aquarium Project View into Store stairs Lab Collections l h Planetarium Northern pass pick-up California East Coast l Earthquake Garden e Islands of Evolution k Rainforests Piazza of the World West f Science (Exits in Garden in Action Aquarium) Reef Lagoon m Garden n Moss Room Cafe Restaurant Penguins i African Hall Information m Academy Cafe Store Entrance Level 1 N Level 1 Swamp Store Level 1 stairs o Philippine Coral Reef p Water r Northern t Amazon Planet California Flooded Lower Level Coast Forest N (Aquarium) s Discovery q Animal Tidepool Lower Level Attraction (Aquarium) Northern California Coast California Academy of Sciences Northern California Coast Educator Guide 03 B. exhibit map Aquarium Map Level 1 Lower Level Rocky Coast Rocky Coast Rocky Reef Sanctuaries & Conservation Estuarine Habitats Tidepool Sandy N Bottom N Northern Northern California California Coast Coast Found on Level 1 and the Lower Level of the Aquarium, the Northern California Coast exhibit focuses on two main themes: California coastal habitats and conservation.

Coast Main ideas: » San Francisco Bay is an estuary, a mixture of fresh water from rivers and salt water from the ocean. Estuarine Habitats » San Francisco estuary is vitally important to us, and to the health of the Pacific Ocean and onshore ecosystems. » Protection and restoration of San Francisco Bay benefits inland and marine ecosystems as well as the Bay itself and enriches our lives. Take a closer look! These animals call the San Francisco Bay home.

Coast Main ideas: » The biodiversity of Northern California’s rocky coast is rich and diverse. Rocky Reef Sanctuaries & » The daily tidal cycle creates a harsh, changing Conservation intertidal environment to which species have adapted. » Organisms that live in tidepools face extreme Tidepool Sandy fluctuations in environmental conditions including Bottom UV light, oxygen levels, temperature and wave action. » Organisms that live on the rocky shore are exposed to waves every day and have adaptations for hanging on and for deflecting waves. Take a closer look! These animals can be found in rocky tidepools.
