Antarctic Iceberg Tracks

[FredBear]

Some time ago I noticed Worldview has the tracks of some icebergs available under the "Events" tag just after the "layers" tag under the "Worldview" title.

This is obviously being updated and is now much more comprehensive (and takes out some of the fun for our own observations?).

Anyway, I attach an active link for anyone interested to try:-

Actually a nice tool, which also provides surface area measurement of the various icebergs.

..in square nautical miles 
Is there any way to automatically convert to metric?

[oren]

I was wondering the same...

There doesn't appear to be one on the site so we'll just have to multiply by 3.43 to get km^2.

Although area is quoted as NM sq., I have measured with their tool bottom right. Measurements are square miles and sq Km. Multiplication factor is approx 2.6 . Neat site thanks for the link.

click on the ruler icon a box pops up with a km mile selector switch

NM defined as 1,852 metres, NM² = 3.43km² - not a nice, useful SI unit! Historical, so still used by some    .    .    , perhaps we have km, mi, NM and NM² all trying to measure things on these maps?
Also I don't think the recorded size of icebergs is likely to be changed unless there is a major break-up? (Suspect there will be no noted change if the icebergs just naturally fray at the edges.)
