Extreme value distributions describe interannual variability in the seasonal North Atlantic phytoplankton bloom
Abstract The North Atlantic phytoplankton bloom depends on a confluence of environmental factors that drive transient periods of exponential phytoplankton growth and interannual variability in bloom magnitude. I analyze interannual bloom variability in the North Atlantic via extreme value theory whe...
