Yes many icebergs are produced today and will be in the future from the very north to the very south of East Greenland, but the size of them are much smaller than they used to be, and remember they are always larger below (90%) the surface than above (10%).
And a keel of 500 meter is not unusual, that is why they often get "stranded" in the middle of the sea.
But the size of them area wise is a different story, very few icebergs above 10 km
2 are being produced on the East Coast of Greenland, if any? (Yes I know there a 2 large calves from Spaltegletscher but they will not enter open water untill their size is reduced the fjord is too narrow for them to pass and there is a small island stopping them too) The iceberg now seen on its way out of the Zachariae Isstrøm system (42 km
2) is an old bull not a calf anymore, it has been sitting in Jøkelbugt for years, the largest calves from Zachariae Isstrøm today is no more than max. 15 - 20 km
2, the only glacier left in Greenland producing calves above 20 - 30 km
2is Petermann Gletscher but they are usually 160 - 200 km
2Yes I knew it the largest fjord system in the world:
