High-resolution temporal sampling of nearshore vertical structure of bioluminescence Mark A Moline*1; JF Case2; O Schofield3 (1) Biological Sciences Department, California Polytechnic State University, San Luis Obispo, CA 93497, USA; (2) Marine Science Institute, University of California, Santa Barbara, CA 93106; (3) Coastal Ocean Observation Laboratory, Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, NJ 08901      *(mmoline@calpoly.edu) A month-long time series of bioluminescence potential was collected at the coastal Long-Term Ecosystem Observatory (LEO-15) site in July 2000. A newly developed bathyphotometer was integrated into an automated profiler system 5 km off the coast in 15m of water. Water samples for taxonomic identification of phytoplankton and zooplankton were also taken simultaneously to quantify the source of the bioluminescence potentials over the month. Additional instrumentation on the profiler made simultaneous measurements of the physical, optical and chemical parameters, providing a context in which to interpret the observed temporal patterns. This time series provides the resolution required to discern behavioral vertical migration patterns, physiological responses to in situ light fields and bioluminescence changes in response to physical forcing events (i.e. upwelling and tidal flushing). This data also allows the time scales of relevant changes in the bioluminescence potential with depth to be quantified, providing a first level estimate at predictability.
