I don't think that this is technically true, since icebergs are made from fresh water and they melt in the salt water of the ocean. Fresh water is less dense, so it will take up a larger volume than that of salt water.
- deelowe 6y agoWhere does the additional density come from that wasn't there already when the iceberg was floating?
- fullstop 6y agoThe amount of salt water displaced by the fresh water ice is equal to its weight, but the melted fresh water will take up a slightly larger volume than the displaced salt water. It is small, but calculable. From what I remember reading, if all of the floating sea ice on the globe were to melt right now, sea levels would rise by about 5 centimeters. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010GL042496 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/201...
- revax 6y agoYes you are right but this is not enough to have a meaningful impact.
