During the year, the outboard cruiser POGO was replaced with a 

 17 -foot fiberglass "Boston Whaler, " powered by a 75-hp. outboard motor. 

 This acquisition increases the consistency of field sampling because of its 

 speed and seaworthiness. The 40 -foot dies el -powered vessel TOMMY BOX 

 was acquired for work in the deeper smd more distant inshore waters. Con- 

 siderable remodeling and hull repairs were required before putting this ves- 

 sel into service. 



During the coming year, because of the limited staff, the tempo of 

 field work will be reduced until the series of data already obtained can be ad- 

 equately analyzed and reports written for publication. This will also prevent 

 collection of data which analysis of existing data may show are not required. 



Series of available hydrographic data and 

 conconaitant biological samples.
