P95.2 core was drilled adjacent to the P95 core (2.5 m. away) \r\nfor evaluation of noise in the record. The d18O correlation between \r\nthe two cores is .80. \r\nThis file contains a summary of microparticle measurements from the 334-m long ice core (P95) drilled in April-May 1995 through the Penny Ice Cap, Baffin Island, Canada.\r\nMicroparticle concentrations and size distributions were measured for a size range of 0.85 to 12 µm\r\nwith an Elzone 280PC multi-channel particle counter equipped with a 30 µm orifice (Zdanowicz et al., 1998).\r\nThe microparticle parameters given below are: \r\nN = total number of particles [0.85-12 µm], expressed in thousands of particles per mililiter of meltwater (10^3 ml^-1)\r\nM = total mass of particles [0.85-12 µm], expressed in micrograms per kilogram of ice (µg kg^-1 or ppb)\r\nThe P95 core was dated back to 7900 yr ago (319 m) by spectral analysis of the electrical conductivity record\r\nwhich tracks seasonal chemical variations (Fisher et al. 1998; Grumet et al., 1998). Beyond 7900 yr ago,\r\nthe depth-age curve was adjusted to match the end of the Younger Dryas-Holocene transition (326 m) dated at 11,550 +/- 70 yr ago in Greenland ice-core records.
