RHUMB- 



Subroutine using AMP to compute the 

 rhumb line (approximation of a chord 

 of a great circle on a Mercator pro- 

 jection) bearing through an MSQLOC 

 area.

See SYNGRID 



Calcomp plotter subroutine which plots 

 alphanumeric characters and symbols. 



Synthetic Bathymetric Profiling System, 



Accessing program which produces a 

 depth range profile on magnetic tape 

 for each MSQLOC area. 



Program which loads gridded bathymetric 

 data into the random access storage 

 device . 



Program which checks longitude of data 

 points and depth values. 



Program which track plots data points 

 on a Mercator projection at the scale 

 of the source manuscript. 



Program which plots contours of the 

 gridded data on a Mercator projection 

 at the scale of the source manuscript. 



Program which transforms synthetic 

 track line data into gridded bathy- 

 metric data at seven points per card. 

 This is the primary structuring 

 program. 



Accessing program which links together 

 the profiles on magnetic tape produced 

 by SYNBAPSl for each MSQLOC area to plot 

 a great circle profile. This program is 

 usually run linked to SYNBAPSl.
