The CTD data obtained so far in OMP has been unsuitable for resolving the BBL. This 

 is due, I believe, to the research interests of those involved in the CTD program and due to 

 instrumentation problems. To help remedy this problem, I would like to participate actively in 

 future OMP CTD surveys. (I am currently on a WOCE CTD/tracer cruise in the South Atlantic.) 

 In addition to some experience and interest in resolving BBLs with CTDs, I can also contribute 

 two CTDs and a bottom finding pinger. No additional CTD cruises are proposed, only that I help 

 in getting the CTD casts closer to the bottom. 



METHODS AND PLATFORMS 



For the observational component of the proposed work, I would use the equipment of the 

 Current Meter Facility of Florida State University. Most of the equipment, as noted earlier, is 

 scheduled to be retrieved from the South Atlantic in 1995, and should be available for reuse in 

 the latter half of 1995. I would intend to integrate my current meter work as closely as possible 

 with moorings being set by others. However, if needed, we have the capability of setting 

 autonomous moorings. Note, that the current meters we use are designed to be data loggers for 

 other, external sensors, and could be used as such. (Should we consider fitting them with oxygen 

 sensors?) 



I would expect to be on the current meter cruises, and I would like to participate in the 

 CTD station work even if that will require going on additional cruises. 



For the numerical modeling component of the work, I propose to continue using the 

 model we now have to help explain what we will observe with current meters and CTDs. 



STRENGTHS AND LIMITATIONS OF PROPOSED RESEARCH 



The strengths of my proposed work are that (1) it would contribute to a better 

 understanding of the currents and the water mass budget in the OMP area (the current meter 

 work), (2) it would yield a better understanding of what the BBL is like in the OMP area (the 

 two BBL speed profiler deployments and my participation in the CTD data collection and 

 analysis), and (3) it would lead to a better understanding of the dynamics of BBLs over sloping 

 bottoms and the importance of the BBL in the OMP area (the numerical modeling of BBLs). 



A possible weakness is that I have proposed using existing current meters where, in some 

 cases, ADCPs might be more desirable.
