The file presents the characteristic Raman wavenumbers of about 200 microinclusions (MIs), with size from 2 to maximum 10 µm, existent in ice samples cut at 7 different depths along the EDML ice core. Their respective Raman intensity divided, for comparison, by the intensity of a Raman peak which is always recorded (the Raman peak centered at ~1047 cm-1) is also given. The ice samples of MIS2 (Marine Isotope Stage 2) age were cut from clear and cloudy ice in order to compare the specific chemistry of the embedded MIs. When observed against a light source the polar ice can appear more or less transparent, therefore the classification in clear ice (CI), considered to have been formed under mild weather conditions, and cloudy ice, which occurs as layers of various width named cloudy bands (CB). The CB ice is considered to have been formed under winter (glacial) type conditions. The Raman signals can be assigned to: mirabilite, meridianiite, gypsum, (natro)jarosite, nitrocalcite, silica, apatite, feldspars (albite, sanidine, microcline, anorthite), titanite, rutile, anatase, carbonaceous matter, sulfate anion, nitrate anion, methanesulfonate anion. Few Raman peaks could not be properly assigned. The frequency of the Ca and Si containing MIs is higher in the CB ice while the number of the [SO4]2- containing MIs is high in the CI. A significant percent of MIs resulted to contain more than one compound (i.e. two different sulfate salts or silica and a sulfate salt).
