yond the Apex by aggravating imbalances both in time 

 and space between organic production and decomposition. 

 37. One hypothesis to evaluate is that the initial effects 

 of sewage-derived inorganic nitrogen is the stimulation of 

 autotrophy in the Bight Apex. The "unused" Apex DON 

 compounds plus the organic compounds photosynthesized 

 in the Apex stimulate heterotrophy. However, the full 

 effect of this heterotrophic stimulation (P/R <<1, low 

 D.O.) is delayed in time and occurs down the plume of 

 the estuary, seaward of the Apex along the New Jersey 

 coast.

 offered constructive criticism. G. Berberian (Atlantic 

 Oceanographic and Meteorological Laboratories) pro- 

 vided nutrient analyses; James O'Reilly and Terrance 

 Smith (University of Rhode Island) gave field assistance 

 with seabed rate measurements; K. Gashlin and A. 

 Fischer gave field assistance with seabed and particulate 

 carbon measurements; and C. D. Litchfield (Rutgers 

 University) provided corollary information. The assist- 

 ance of the officers and crew of the NOAA ship Albcitross 

 IV under Captain Beattey, and of J. LeBaron for data 

 processing and M. Cox for graphic illustrations, is appre- 

 ciated.
