Subsets of samples are analyzed for dissolved silica (also called reactive silica or silicate), major cations and anions, and the natural abundances of N15 and C13. Stream water samples were collected weekly during non-storm flows in winter, bi-weekly during summer. During winter storms, samples are collected hourly (rising limb) or at 2-4 hour intervals (falling limb) Santa Barbara Coastal LTER stream_chemistry SBCLTER_Categories Freshwater Terrestrial Carbon Nitrate Nutrients KNB Surface Water Chemistry Nitrogen Compounds Nutrients Organic Matter Suspended Solids GCMD Organic Matter Nutrients LTER Core Research Area The user of SBC LTER data agrees to contact the data owner (i.e., the SBC investigator responsible for data) prior to publishing.

The primary research objective of the Santa Barbara Coastal LTER is to investigate the importance of land and ocean processes in structuring giant kelp (Macrocystis pyrifera) forest ecosystems. As in many temperate regions, the shallow rocky reefs in the Santa Barbara Channel, California, are dominated by giant kelp forests. Because of their close proximity to shore, kelp forests are influenced by physical and biological processes occurring on land as well as in the open ocean. SBC LTER research focuses on measuring and modeling the patterns, transport, and processing of material constituents (e.g., nutrients, carbon, sediment, organisms, and pollutants) from terrestrial watersheds and the coastal ocean to these reefs. Specifically, we are examining the effects of these material inputs on the primary production of kelp, and the population dynamics, community structure, and trophic interactions of kelp forest ecosystems.
