A sample from Kirkjubæjarklaustur has been analyzed, which was
taken around 1h on 22 May. The grains are glassy with micro crystals
of plagioclase. Samples well sorted.

The fluorine content is approximately 850 mg/kg according to chemical analysis carried out by the Institute of Earth Sciences, University of Iceland, on a sample taken 19 April. An earlier sample since 14 April only measured 25-35 mg/kg of fluorine because the water vapour from melting ice rinsed the ash. When the eruption progressed, water became less

that, the detrended timeseries would have had a net difference of
zero if the negative values had not been set back to zero. This shows that over the 39 years of
data, there was a slight precipitation increase for this grid-point. This trend has been removed,
resulting in a detrended, almost flat dataset.
