1. A Postdoctoral Program in Numerical Ocean Modeling. The national 

 supercomputing initiative has three thrusts -- development of a class nine computer, academic 

 access to present supercomputer centers, and training of research scientists to develop and make 

 effective use of vector codes. NSF also has an advanced computational initiative which has 

 established new supercomputer centers and an academic computing network known as NSFnet, 

 and has provided some local equipment and facilities. Availablility of 20% of NCAR's new CRAY 

 XMP is especially important to oceanographers. This CRAY will be linked by satellite network to 

 Miami, Oregon State, WHOI, and other institutions. 



Now that we have these badly needed facilities, development of a program to train scientists in 

 numerical ocean modeling seems prudent, especially in light of future modeling and data 

 assimilation requirements. We propose to establish a five-year program in Numerical Ocean 

 Modeling for postdoctoral scientists with training in Applied Mathematics, Computer Science, 

 and Ocean Sciences. These postdoctoral investigators would be resident at academic institutions. 

 Funding for the program would provide salary support, local computing and communications, 

 and travel for ten investigators. Funding needed is $1M per year beginning in FY 1989. 



2. Current Meters. Key elements in advancing our understanding of ocean flow during the 

 past 20 years have been the current meter and the intermediate mooring. Aging, obsolete 

 equipment (some current meters were purchased 15 years ago) must be replaced with new 

 equipment. The level of funding available to the program has not allowed maintenance of current 

 meter and acoustic release inventories. At least $.7M annually over the next two years is 

 required to purchase new equipment and to return these inventories to a level of sufficiency for 

 the science currently supported. 



3. Acoustic (Pop-up, SOFAR, and RAFOS) Floats. Autonomous listening stations (ALS) 

 and acoustically-tracked, neutrally buoyant (SOFAR) floats have recently been improved both 

 mechanically and electronically and redesigned to take advantage of microprocessor technology . 

 Present scientific projects in the North and Tropical Atlantic would benefit greatly from 

 additional SOFAR floats (40) and listening stations (5) at a total cost of $.7M. We would like to 

 acquire a suite of five pop-up floats for future Gulf Stream or Arabian Sea studies and to expand 

 the RAFOS float capability for related studies at a cost of $.7M. 



4. CTD Group Support. In the past, two CTD groups have been available to meet large 

 project needs; both groups have recently become marginal in their capabilities due to a variety 

 of problems (equipment failures and losses, relocation, management problems, and decreased 

 funding for field work). We think that it is important to reestablish both groups with an 

 up-to-date data processing facility ($.IM), new at-sea and in situ sampling equipment 



($.2M), and base salary support for a few high quality technicians/engineers ($.3M) starting 

 in FY 1989. Salary support should continue for an additional four years.
