GP DEP 1 O2 and T
Great Pond, Station DEP1:  Oxygen Concentration 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 upper panel shows temperature as a function of depth and julian day.
 
Notice the elevated total phosphorus concentrations relative to Long Pond.  Also notice the low oxygen concentrations below the thermocline.
