What a great trip. We got lots of samples that we wanted and were blessed with the weather. The Landrover didn´t break down, we saw old friends and old haunts and explored some beautiful places that I had never seen before.
|Sampling Layer H tephra from Eyjafjallajökull, deposited around 1500 years ago|
We should now have enough data points of thickness and samples for grain size analyses and deposit density to make significant progress with plans.
|Eyjafjallajökull 2010 and Grímsvötn 2011 tephra being blown around|
Some things that really struck me while we were away are a) that exponential thinning of tephra layers is certainly very close to being how things are (wow, it is hard to find where the layer goes from a trace to zero!), b) Þórsmörk is stunning especially if you cross a few dodgy looking paths and head away from the tourists, c) tephra blows around a lot after it is deposited so how can we assume geological records are good representations of the actual tephra at time of deposition? and d) Fieldwork is great and even better with good company (thanks Iveta).
