The Santa Barbara Coastal Long Term Ecological Research (SBC LTER) site is an interdisciplinary program established in 2000 to understand the ecology of coastal kelp forest ecosystems. Our research is focused on the nearshore waters of southern California, where ocean currents and climate are highly variable with season and longer-term cycles, including the El Niño-Southern Oscillation and the Pacific Decadal Oscillation. SBC’s principal study domain is a 10,000 square kilometer area of the northern portion of the Southern California Bight that includes the Santa Barbara Channel and the steep coastal watersheds, small estuaries and sandy beaches that border the Channel.
