[ecco-support] gcmfaces_lines_transp and calc_trasnports

[Paola Cessi]

I am confused as why the values of transports  across a section, as given by calc_transports, change when the endpoints of the section, as given by calc_transports, are changed by one or two degree on land points. For example, if I change gcmfaces_lines_transp([152 -71],[-30 -30],{'30S Pacific'}); to gcmfaces_lines_transp([152 -70],[-30 -30],{'30S Pacific'}); the transports are different even though
both 70W 30S and 71W 30S are on land (at least on google maps). Why does this happen? Is there documentation on the actual land point in ECCO, given in lat-lon? 

Thanks,

Paola
