A Technique for Measuring Microparticles in Polar Ice Using Micro-Raman Spectroscopy

Figure 5

The distribution of microparticle chemical forms found in ice samples taken from Termination I of the Dome Fuji ice core. 340 m: Holocene, 382–502 m: Termination I, 576 m: Last Glacial Maximum. The numbers of microparticles measured at each depth are 87, 106, 101, 161, 237, and 66, respectively, (a total of 758 particles). The numbers of microparticles in the “no Raman signal” category are 18, 3, 2, 37, 44, and 15, respectively. The numbers of “broken particles” are 4, 1, 1, 4, 4, and 5, respectively.
