Fig. 1. Synthesis of organic phosphorus in water from Chocolate Lake, Nova 

 Scotia. Water was kept in the dark throughout, and prior to the test was 

 stored twenty-four hours and filtered. The decline in total P is attributed to 

 uptake by sessile organisms. Solid "organic" line, direct observations; dotted 

 "organic" line incorporates correction for loss to sessile forms (i.e., solid 

 line points plus 100 minus values in top line).
