Thanks again, Roy! I tried your method, which sounded promising, but ran into
another glitch. GDS provides .info, .dds, and .das URLs but does not provide a
.html OPeNDAP access form. So, a URL to
http://apdrc.soest.hawaii.edu/dods/public_data/Model_output/HYCOM/hycom_hawaii_0.04
in my TDS tries to go to hycom_hawaii_0.04.html, which doesn't exist. TDS
automatically tacks on the .html extension when using the OPeNDAP serviceType.
If you or anybody has further suggestions, thanks in advance!
Best Regards,
John Maurer
