A STUDY OF THE TYPES, SEASONS OF ATTACHMENT, 



AND GROWTH OF FOULING ORGANISMS IN THE 



APPROACHES TO NORFOLK, VIRGINIA 



I. INTRODUCTION 



In April 1956 the Division of Oceanography initiated a study to 

 determine the biological fouling complex and the rate of fouling on test 

 panels near the bottom in the entrance to Chesapeake Bay. Specific 

 objectives of the study were: 1) to assess the predominant foulers, 

 their seasons of attachment, and their rates of growth in the channel 

 approaches to Chesapeake Bay, and 2) to determine the feasibility and 

 value of this type of data collection in other harbors and approaches. 

 In addition, the information might be used to determine the length 

 of time objects had been on the bottom where time of submergence 

 was unknown.
