Synchronicity between ice retreat and phytoplankton bloom in circum-Antarctic polynyas
International audience Phytoplankton in Antarctic coastal polynyas has a temporally short yet spatially variant growthwindow constrained by ice cover and day length. Using 18-year satellite measurements (1997–2015) of seaice and chlorophyll concentrations, we assessed the synchronicity between the s...
