Ram, M., Stolz, M. and Koenig, G. (1997). Eleven year cycle of dust concentration variability observed in the dust profile of the GISP2 Ice core from central Greenland: Possible solar cycle connection. Geophysical Research Letters 24: doi: 10.1029/97GL02521. issn: 0094-8276.

We have re-examined the dust record from the GISP2 ice core retrieved from central Greenland and found that the background dust concentration is modulated with a period of 11 years all the way back to ice from at least 100,000 yrs BP. The only known, relevant, naturally occurring phenomenon with such a period is the well-known solar cycle. We believe that the background modulation we observe is related to the solar cycle and discuss this hypothesis. ¿ 1997 American Geophysical Union
