dataset: Standard station location and cast distance tables
dates: July 17, 1995 to August 15, 1995
location: N: 22.5 S: 10 W: 57.3 E: 68.75
project: Arabian Sea / TTN-049 Process Cruise #4 (Middle SW Monsoon)
ship: R/V Thomas G. Thompson
This data set consists of Arabian Sea Standard Station locations, as agreed
upon in August, 1996 at the First Arabian Sea Data Workshop, Durham, NH.
Also given are all casts whose locations were within 20 kilometers of
each standard station, listed with appropriate cruise indicator.
May 1998 Note:
Steve Gaurin reminds us: "the cast location data includes
hydrographic casts only; trace metal and other casts are not listed."
These standard station location and cast distance tables were generated by an IDL program
which reads each cast's ".pos" file and employs a great circle distance calculator to find the
standard location to which the cast was closest, within a maximum distance of 20 km. The program was
modeled after code written by Steve Mitchell at Advanced Technology Information Network, California State University at Fresno. His great circle distance calculator and a listing of the C code are available
upon request.
The results of the program have been compared to a Garmin GPS unit and have been found to
be reliable. Please use these tables and distribute them freely. If you have any questions, contact
