Seagrass Ecoysystem Study (SES) 



This study was begun in July 1974 to provide informa- 

 tion about the benthic marine ecosystem, particularly the 

 dynamic processes by which seagrass ecosystems are main- 

 tained, the distribution of these ecosystems, and their contri- 

 bution to the seas. Initiation of these research activities has 

 resulted from increased awareness of the importance of near- 

 shore waters in the productivity of the ocean and the vulnera- 

 bility of these waters to man-induced changes. The increased 

 emphases on nearshore renewable resources led to recognition 

 of how little is known about this important ecosystem. 



The Seagrass Ecosystem Study generally addresses three 

 main questions. What are the contributions of seagrass eco- 

 systems to food webs, nutrient and mineral cycling, and 

 coastal stabilization? What processes in seagrass ecosystems are 

 affected by environmental changes or man-induced perturba- 

 tions? Are there structural patterns in these ecosystems that 

 allow them to persist in changing environments? 



The SES program has initiated special field studies and 

 laboratory experiments to answer these questions. Later phases 

 of study will emphasize coordinated, intensive field studies and 

 establishment of a network of national and international field 

 sites for follow-on experiments. 



Participants in the SES programs are identified in table 

 15. International collaboration is maintained through the Inter- 

 national Seagrass Committee. Its members include Tom Fen- 

 chel, Denmark; C. den Hartog, The Netherlands; Akihiko Hat- 

 tori, Japan; C. Peter McRoy and Patrick L. Parker, United 

 States; and J. M. Peres, France.
