The physical structure of the water column was characterized by and intrathermocline eddy(ITE) in 2005, whereas the UWS remained distant from the sampling transect in 2007. Water column structures appeared to be highly stratified, and nutrients in the surface waters were totally depleted at all stations. In 2005, an exceptionally high concentration of Chlα(5.5㎎m-3) was measured below the surface mixed layer in the eddy core (station D3), and values of ~ 2.5㎎m-3 were observed at the eddy edge (station D2 and D4). Formation of and ITE efficiently mixed surface and deep-ocean waters, the latter supplying sufficient nutrients to generate and extremely high concentration of Chlα at the base of the subsurface layer. Overall, the results indicated that the anticyclonic UWE plays a key ecological role in supporting substantial phytoplankton biomass in the nutrient-depleted surface waters in summer and maintaining high benthic mineralization in the deep-sea sediments of the UB.

This approach is potentially problematic given the polymorphic lorica during this organism's life cycle. We isolated a population of F. ehrenbergii from the coastal waters of Incheon, Korea, and revealed its infraciliature using the protargol staining method. Phylogenetic analysis based on small subunit rRNA gene sequences was also performed. Results showed that this population possessed 16 collar membranelles (CM) and about 100 somatic kineties. These features are highly conserved, even in later dividers. As such, the number of CM and somatic kineties can be used as key characteristics for identification of Favella species.
