Long Pond, Station DEP1:  Oxygen consumption (AOU) in Gmoles/meter as a function of depth and julian day.  Secchi Depth is plotted as yellow triangles.  Total phosphorus concentrations are plotted as stars scaled to concentration.  The lower panel shows fluorescence as a function of depth and julian day.

 

The fluorescence maximum below 8 meters from days 200-225 is probably due to plankton bloom below  the thermocline.
