600 square miles and 500 feet thick is 237 cubic kilometers of ice.  It would take 361 km3 to raise sea level by 1 millimeter, so this is about 2/3 of a mm of sea level rise.  By comparison, Antarctic sea level rise has averaged about 0.4 mm/year over the past few decades (faster more recently).  On that scale, this one iceberg calving event seems quite significant.  But it's also possible I screwed up the math.

Since ice is less dense than water the volume of the ice berg is slightly higher than the liquid water that it contains.

That means the melting of this floating block of ice will slightly lower the sea level, but not enough to measure.

Sea water isn't fresh. iat's saltier and thus denser. Melting sea ice, which is pretty fresh, raises sea levels by lowering the density of sea water.

This particular event will not affect sea levels, and is not directly caused by climate change.

I guess I should add that it isn't going to raise sea level by that amount. Or rather, it did, when the ice shelf first formed. The point was that it represents a significant amount of ice.

Your math is ok, but you both messed up the problem. This isn't land ice running into the sea.  This is calving from a floating ice shelf.  Only about 9% by volume of this iceberg was not in the ocean the whole time. The whole thing contracts by about 9% much upon melting.

The net sea level rise is 0 for this event.

There's also the fact that this calved off an already-floating ice sheet.  It's like taking an ice cube out of your drink, chopping it in half, and putting both halves back in: you won't change the water level in your drink.  If this was land-borne ice that wound up in the sea, it would raise sea levels some amount.  But already-floating ice breaking up into smaller chunks changes nothing.  It does increase the surface area of the ice exposed to melting, meaning it will melt faster than it would as a single iceberg, but as zeaper says, melting floating ice actually lowers sea level.

I clarified above. The point wasn't to say that this is a big new contributor to sea level rise, but to put the volume involved on a meaningful scale.  Cubic meters or even "area in Rhode Islands" don't mean much to people; units of "sea level equivalent" are more tractable.

It is possible that this particular section of ice may have been undercut prior to calving, so it may not have been floating 100% in the water at that time.  I think the correct answer is somewhere between 0 and 2/3mm, but probably closer to the zero end.  If the calving was observed and any kind of wave was generated (as opposed to merely an opening between the shelf and the berg) then there will be some amount of sea level rise associated with the event.

Guys, I'm trying to verify the sea level measurement changes that you've been throwing around in this thread and I got some seriously bad news. Over the last several hours the sea level has risen several FEET, meaning we must have got HUNDREDS of these farking icebergs breaking off and melting into the ocean.
