Chronicles of hypoxia: Time-series buoy observations reveal annually recurring seasonal basin-wide hypoxia in Muskegon Lake - A Great Lakes estuary

Daily averaged temperature (a), chlorophyll (b), and dissolved oxygen (DO; c) at the Muskegon Lake Observatory during 2011-2013. These data show the annual development of thermal stratification, onset of mild (DO below orange line) and severe (DO below red line) hypoxia, and associated phytoplankton blooms as indicated by changes inb chlorophyll.240
