WATER MASS VARIABILITY, NUTRIENTS, SEDIMENTS, AND PHYTOPLANKTON PIGMENT CONCENTRATIONS IN THE SANTA BARBARA CHANNEL
 
The Plumes and Blooms project is a coordinated time series project of field observations and satellite imagery analysis with the goal of understanding the driving mechanisms and impacts of sediment plumes and phytoplankton blooms in the Santa Barbara Channel. Beginning in August of 1996, optical measurements, with corresponding physical, chemical, and biological sampling, have been made twice monthly along a seven station transect across the Santa Barbara Channel. A large range of environmental conditions have been sampled in the first two years of the project. Utilizing principle component analysis, we investigate the covariance between water mass, nutrient concentration, and response of phytoplankton communities under varying environmental regimes. The first three modes of variability account for 99% of the total variance and support the observed seasonal variations in community structure and water mass characteristics. The channel represents a complex marine environment and is primarily influenced by three distinct water masses, upwelling, Southern California Bight water, and California Current water. Each water mass has a unique temperature, salinity, and nutrient signature which impacts the phytoplankton community structure.
