Spectrum Data Management has always found the staff at Merlin Datawise to be very pleasant, helpful, and knowledgeable about archiving seismic data. When performing our annual offsite storage audit of our data at Merlin Spectrum Data Management staff has always received a warm welcome and valuable feedback of our archive process. For this audit process Merlin provided British Standards Institute recommendations for digital media preservation and detailed records of compliance with these standards. Their historical knowledge of seismic data surveys, thorough inventory, and willingness to share their experience has aided in Spectrum’s development of Seismic Data Inventory Policies and Procedures.
