Phytoplankton bloom, possibly Rhizosolenia

Post by leonardturner »

I recently witnessed an overnight bloom in the Gulf of Mexico; the surface of the water became covered with a highly reflective materiel which revealed a great number of these organisms. I'm no diatomic expert, but they seem to be more compatible with Rhizosolenia than Pseudonitzschia. Any input would be appreciated!

Hi,


i would go with Proboscia alata (= Rhizosolenia alata).

compare with this:

if the cells have a high oil content they can float - alternatively air bubbles can get trapped in the tangled raft of cells and give buoyancy.

interesting - thanks for posting

Brian
