Focus on Ecosystems at the Land-Ocean Margin Santa Barbara Coastal Long Term Ecological Research
LTER Objective To attain a predictive understanding of ecological phenomena over long temporal and large spatial scales LTER Mission To provide the scientific community, policy makers, and society with the knowledge and predictive understanding necessary to conserve, protect, and manage the nation's ecosystems, their biodiversity, and the services they provide. US National Science Foundation’s Long Term Ecological Research Network Established 1980
terrestrial / marine tropical / temperate / polar pristine / urbanized / managed habitats include: forests, deserts, grasslands, alpine, tundra, agricultural lands, dry valleys, estuaries, barrier islands, coral and rocky reefs, and the pelagic ocean US LTER Network 26 sites representing diverse ecosystem types

Santa Barbara Coastal Long Term Ecological Research Primary Research Areas 1.Land and ocean processes that determine the type and quantity of materials delivered to the coastal ocean. 2.The relative importance of land and ocean processes for primary production, biodiversity and food web structure of kelp forests. 3.Effects of disturbance & climate change on the entire coastal ecosystem
Coordinated long-term measurements General Research Approaches Manipulative field experiments Shorter-term measurement intensive process studies Synthesis through Modeling & Integrated Analyses
Hydrology and water biogeochemistry during base flow conditions and storm flow events The effects of land cover, land use and fire on chemical and biological constituents of runoff Nutrient and carbon processing in streams and soils. Marine subsidies to sandy beach communities Terrestrial Research Topics
Ocean circulation and mechanisms of material transport Phytoplankton productivity, distribution, & succession Sources and fate of dissolved & particulate organic matter Satellite remote sensing of ocean color and kelp distribution to examine regional to basin scale processes on kelp forest ecosystems Oceanographic Research Topics
Effects of disturbance and species interactions on community structure Patterns and controls of net primary production Effects of climate change on foodweb diversity and complexity Transport and processing of different sources and forms of nitrogen Kelp Forest Research Topics
Objective: Develop a storage system for metadata and data that facilitates synthesis and provides long-term management and accessibility Information Management
