DESCRIPTION:Speaker: Xiuning Du\, CIMRS\, OSU & NOAA \n\nTopic: The diatom 
 Pseudo-nitzschia (PN) blooms annually in coastal waters of the California 
 Current. Because of anomalously warm ocean conditions in 2015\, the U.S. w
 est coast experienced the most persistent\, wide-spread and toxic PN bloom
  on record. PN produced a neurotoxin domoic acid (DA) which marine fauna b
 ioaccumulated from feeding on PN cells and became a human health hazard. F
 or the first time\, the most valuable Dungeness crab fishery in Oregon was
  closed. Since then\, the crab fishery opening has been annually delayed a
 nd/or closed partially due to the above health concerning level of DA dete
 cted in crabs. While we are understanding more about the general seasonali
 ty of PN blooms on the OR coast and its nonlinear correlation with DA prod
 uction\, we have also seen that observed surface toxic PN blooms transfer 
 its toxicity effects to Dungeness crabs are very timing/season dependent. 
 There is a range of temporal and spatial opportunities for PN (and DA) rea
 ching crabs in conjunction with local environmental and biological effects
 . By far\, little information about PN cell presence and abundance in the 
 deep water environment on the OR. However\, examining the direct availabil
 ity of toxic PN cells in the nearby environment where crabs live opens up 
 thoughts on mechanisms of DA post-bloom lingering effects on crabs.
