Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations. STUDY NOTES: Snowpits were excavated in 1994 and 1995. The 333.78m. P95 core was drilled to the bed in April-May 1995. The 89m. P95.2 core was drilled adjacent to the P95 core (2.5 m. away) for evaluation of noise in the record. The d18O correlation between the two cores is .80. The 177.91m. P96 core also reached the bed. It is located approximately 16 km. from P95. The P95-P96 correlation of d18O on 40-year segments is .3 to .5. ADDITIONAL REFERENCES: Fisher, D.A., R.M. Koerner, G.A. Zielinski, C.P. Wake, C.M.
