Icebergs off SW Ireland
« on: August 02, 2009, 15:51:19 »
Was browsing the net and came across this image which shows exceptional sightings of icebergs, a few of which were noted off the Kerry coast...



Very interesting... I wonder will we see anything of the likes in our lifetimes?
If it doesn't rain between the showers, it'll be fine.

Here are the years in an orderly list that appear on the map outside the usual zone.

1842
1881
1881
1886
1901
1903
1907
1908
1912
1913
1917
1918
1921
1936
1944
1948
1951
1958
1958

Notable absences are 1890s, 1920s and 1930s. I guess with the emergence of transatlantic flight that there are no new records from the 1960s to present.

Would be a nice sight to see one in the Irish sea. A nice wintry spell with it would be very welcome also.

This is speculation, but it seems to me that icebergs would not necessarily be seen at their most southerly limits in the coldest winters, as very cold weather, which would also tend to be calmer, would tend to keep ice from breaking up, whereas mild weather with strong winds would tend to make ice move (admitedly it would tend to be winds from the north which would blow icerbergs to the south, and north winds tend to be cold in the North Atlantic). Perhaps I am completely wrong on this.

I have read recently (I think it was on the UK Weatherworld forum) that the reason the iceberg (which was said to be 50-100 feet high, and presumably there were several hundred more feet below the water level) which collided with the Titanic in April 1912 was further south than usual was because of strong persistent strong North-easterly winds (although the night, 14th/15th April, when the collision occurred was clear and calm).  As the map showing the location of icebergs which were seen unusually far south shows, on one occasion an iceberg was seen south of the Azores!

Is there a definition of an ice-berg, as opposed to an ice-floe? Certainly the sea around the British Isles has frozen locally in severe winters, even in recent years (I think this may have happened very locally even in February 2012) but I had not heard of "icebergs" off the Irish coast before. I do remember reading that one winter many years ago (it could have been in 17th, 18th or 19th centuries) that an Eskimo drifted on an ice floe to the coast near Aberdeen. I think Polar Bears have also been seen off Iceland for similar reasons.
