Chlorophyll Time Series in Humboldt Bay, Greg Crawford and Frank Shaughnessy presented a poster entitled, "CICORE Chlorophyll Time Series in Humboldt Bay, California: Monitoring Ocean and Bay Conditions", at the recent Ocean Sciences conference in Honolulu, Hawaii (Feb. 20-24, 2006). Crawford and Shaughnessy argue that, at high tide, the water properties are more indicative of nearshore ocean waters, while at low tide they are more representative of waters over Arcata Bay. "Bursts" of high chlorophyll concentrations (~20-30 ug/L) are likely associated with a response to upwelling-favorable conditions in the coastal ocean. These data are helping to fill a gap in monitoring nearshore conditions up and down the west coast of North America.
In spring and summer 2005, there was very little upwelling off the coast of Oregon and Washington State, which caused some large problems in the marine food web this past year. Conditions in central and southern California were much less affected. The CICORE chlorophyll data analysis presented here help to fill in a gap in coastal monitoring, showing quite clearly reduced levels in chlorophyll in 2005 (compared with 2004) for much of May through July.

Patterns and Potential Drivers of Turbidity in Humboldt Bay, CA. Frank Shaughnessy & Kathleen Williamson, Department of Biological Sciences, Humboldt State University. The objective of this study is to describe one aspect of
this variation, turbidity, and determine if it is related to tidal
exchange, precipitation, or wind.
