Dusty digits

We have already reported on Kelman Archives’ rationalization of Gulf Canada’s seismic archive last year (PDM Vol 4 N° 10). Kathy Taerum gave an account of this work at last year’s SEG conference and spiced her erudite account with a poetic list of archive objects encountered. Some of the verses, perhaps like some of the tapes, are blank.
