The Bjurböle L/LL4 meteorite slammed through 40 cm of solid ice and
broke into fragments, the largest of which weighed 80kg* - the total
weight was about 330-400 kg. The diameter of the hole in the ice
measured 425 x 350 cm. The depth of the water at the impact site was 90
cm and the sea-floor consisted of soft organic mud. There were numerous
splashes of mud round the impact hole up to a distance of 20 to 25
meters. The meteorite was finally recovered from a depth of 6 meters
below the surface of the water in the clay layer underlying the mud
layer.
* 80.2 kg, 21 kg, 18 kg and 17 kg.
Best wishes,
Bernd
