GP DEP2 O2 and T
Great Pond, Station DEP2:  Oxygen Concentration as a function of depth and julian day.  Secchi Depth is plotted as yellow triangle.  Total phosphorus concentrations are plotted as stars scaled to concentration.  The lower panel shows temperature as a function of depth and julian day.  The pink stars on the lower panel are total nitrate concentrations.  The inverted, red triangles are iron concentrations in nM.
 
Notice the elevated total phosphorus concentrations at depth relative to Long Pond.  Also notice the low oxygen concentrations below the thermocline.  Iron does not appear to be limiting in Great Pond.
