Well, I didn't look hard, and I wasn't sure the projection, and I apparently don't know Black Sea from Australia.

In any event, this is how you access the data you are interested in. If you want to output to a text file, you'll have to loop over the data

for lon_idx = 0, n_elements( bsloni ) - 1 do begin
for lat_idx = 0, n_elements( bslati ) - 1 do begin

print, bsloni[ lon_idx ], bslati[ lat_idx ], bsst[ lon_idx, lat_idx ]

endfor
endfor

I think that should be what you're looking for. (check the documentation for formatting and writing to files.)
