How are under ice phytoplankton related to sea ice in the Southern Ocean?
Little is known about Southern Ocean under-ice phytoplankton, despite their suspected potential—ice and stratification conditions permitting—to produce blooms. We use a distributional approach to ask how Southern Ocean sea ice and under-ice phytoplankton characteristics are related, circumventing th...
