What did we learn?

 

We returned to the North Atlantic in May to continue trying to understand why white sharks might be foraging in anticyclonic eddies.  As sometimes happens, we were surprised to learn that in anticyclonic eddies (ocean desert) the amount of stuff (biomass) in mesopelagic ecosystems (those at depths of 200 – 1,000 m) appears to have an inverse relationship with phytoplankton biomass at the surface.
