My understanding as well. The list application is essentially the API
for the JGOFS DBMS.

You can run it from the command line as well:
from $LAS_root/server/bin
./list -n -c -f test

There is also a log file created in:
$LAS_root/server/log/JGOFS_request.txt

which shows the list command being executed by LAS in response to a user
query.

Here's an example of a list command from that log file from my server:
bin/list -z -m -f -n
'//usjgofs.whoi.edu/US_JGOFS/Arabian_Sea/bottle_arabian(TCO2,TOC_kg,TON,cast,date,depth,lat,lon,sta,lon>=54.0,lon<=71.0,lat>=8.0,lat<=26.0,depth>=0,depth<=4900,date>=19950101
00:00:00,date<=19951231 00:00:00)'

You can see that LAS issues a list command to retrieve data from a JGOFS
object. The 'single-quoted string' is a full JGOFS object specifier,
with projection (list of parameter names) and selection (data value
ranges) qualifiers, a comma-separated, parenthetical string) to subset
the data from the full object.

You can try that one too from the command line, but pipe it to less (the
-n option means non-stop listing)

Yes, that's my understanding.

The development of the LAS-JGOFS and support for in situ data happened
over several years, and is still being improved.

Does anyone (Jon ?) know if there was ever any documentation written to
explain the technical details of the LAS-JGOFS, in situ data interface?

Thanks, Cyndy
