"Ash covered icebergs from the Grímsvötn volcano eruption" may not be totally accurate. True these icebergs are full of ash, and true much if it probably comes from Grímsvötn. However, none if any, comes from the recent 2011 eruption in Grímsvötn. This ice which breaks into the Jökulsárlón glacier lagoon is packed with history. This ice originally came down as snow far up on the glacier, decades or centuries ago. There it would snow for many years, until an eruption occurred. At that point a layer of ash, just as in the recent eruption, would cover the entire glacier. The next year it begins snowing again and that layer of ash gets covered in ash. The Vatnajökull glacier gets covered by ash in layers of variable thicknesses many times over a century. When the ice finally breaks into the lagoon, these lines become visible. (If you want to be picky, some of these lines are not ash, but most are, so lets keep it simple in this post.)
So MSNBC has got it wrong this time. The really nice pictures it has of the paddle boarders on Jökulsárlón, have nothing to do with the recent Grímsvötn eruption.
However there was plenty of new ash on these ice bergs which can be seen in other places.
