aBox = 10 feet of core.

bAGI (1999). This is a minimum estimate.

cAGI (1997) and NRC committee survey responses, 2001.

dUSGS (120,000), ODP/DSDP (197,905), USACE (Alaska)—NRC committee survey responses, 2001, DOE (Yucca Mtn), and AGI (1997).

eAGI (1999) reported 3.5 million boxes of core in all major oil companies; it then reported 1 million boxes potentially available for donation, together with other types of data. We assumed that this ratio of 3.5 total to donatable material was valid for all other types of data listed in the AGI report.

fNRC committee survey responses, 2001.

gUSGS; NRC committee survey response, 2001.

hUSGS and ODP; NRC committee survey resonses, 2001.

iODP; NRC committee survey response, 2001.

pElwyn Griffiths, ExxonMobil, personal communication, 2001. Estimate is for areas with known 3D coverage. An uncertainty of 20 percent is estimated due to an unknown amount of data from areas with more than one seismic survey.

qIncludes offshore industry data copies submitted to MMS; Dellagiarino et al. (2000) (16,094); 1,667 other, AGI (1997).
