An overfishing-induced trophic cascade led to decimation of WFS zooplankton, with a subsequent increment of bacteria-mediated export of sea spray-entrained, wind-borne HAB aerosols to adjacent humans, comprising 48% of the annual net primary production of minimally-grazed HABs.
- •
Unusually strong upwelled nutrient supplies for otherwise Si-limited diatoms, with less susceptibility to oil poisons, allowed these retrograde diatom competitors to win against HABs during the Deepwater Horizon oil spills.
- •
Return of usual oligotrophy led to reoccurrence once more of HAB fish killers and human asthma triggers.
