The new ice-breaking vessel R/V Electra af Askö is 24,3 metres long and 7 metres wide. It is equipped with technical instruments for water- sediment- and geophysical sampling. Modern ship technique and low-impact engines gives her exceptional functionality to work in a larger geographical area than earlier possible within the Askö Laboratory vessel fleet.
