measure primary production using fluorescence, and to measure the production and consumption 

 of dissolved oxygen. The moorings are scheduled to be recovered in July 1994. The primary 

 objective of this effort is to develop moored measurement techniques to close the oxygen budget 

 on continental margins. 



It is technically possible to make moored measurements of dissolved 2 over periods of 

 2-4 months that can be used to investigate the carbon cycle.
