Are the phytoplankton and krill found in the Palmer Deep Biological Hotspot transported there or is it a permanent habitat?
What is responsible for the concentration of phytoplankton and krill above the mixed layer at the Palmer Deep Biological Hotspot?
What is responsible for the concentration of phytoplankton and krill below the mixed layer at the Palmer Deep Biological Hotspot?
Can 3D models be used to show the transport pathways that these phytoplankton and krill take to get to the Palmer Deep Biological Hotspot?
The Palmer Deep Biological Hotspot is a result of the surface transport of remote phytoplankton and krill, not local production alone.
Convergent features in the surface mixed layer, targeted by Adelie penguins, are driven by local winds and tides that concentrate the food web above the mixed layer.
Convergent features below the mixed, layer, targeted by gentoo penguins, are driven by tides and the underlying bathymetry that concentrate the food web below the mixed layer.
A 3D model will show different transport pathways and food web concentrating mechanisms in known WAP hotspots compared to non-hotspots.
