Bioluminescence and in vivo Chl fluorescence were not correlated February 12 1995 at station 3 r p however bioluminescence was still significantly correlated with temperature r p . On June 13 1995 bioluminescence and in vivo Chl fluorescence were significantly correlated r p . Bioluminescence and beam attenuation r p and bioluminescence and temperature r p were significantly correlated. Beam attenuation was significantly correlated with in vivo Chl fluorescence r p . These correlations improved as the mixed layer became shallower in June Figure 21 in comparison to the deeper mixed layer observed in November 1994 and February 1995 Figure 21 . 4. Discussion The data show that bioluminescence changes seasonally in the Southern California Bight coastal waters with a maximum and minimum signal in the spring and fall in SDB Figures 2 14 17b 19a . A winter maximum and summer minimum in bioluminescence was measured at SCI Figure 2 17a . In SDB and SCI we observed a change in the dinoflagellate species composition over a year and its contribution to bioluminescence. We also observed a seasonal change in species composition summer to winter at SCI and within the bight Figures 8a 9 10 . Chlorophyll a also showed similar seasonal trends with respect to location Figures 18 19 . However measured monthly means of bioluminescence did not correlate with Chl a either at SDB or SCI. Mean monthly surface seawater temperature did not correlate with mean monthly bioluminescence at either site that is maximum bioluminescence did not always correlate with either maximum or minimum seawater temperatures Figures 11 12 although minimum bioluminescence was measured during the coolest water temperatures winter at SDB in 1994 and 1996. The largest peak in .
