The oceans have a circulation among them, so that the densities tend to be close. The addition of water in the Arctic ocean is mainly from melting ice, whereas in the Atlantic it is rain and water from rivers. I believe, given the relative sizes of the two oceans, and their replenishment sources, that the Arctic Ocean would be the less dense, and therefore the Atlantic would provide more buoyancy.

One of the global climate change concepts is that increased melting of Greenland ice will make the water less dense and it will ride on top of the Gulf Stream which is more dense and will therefore sink, causing more frigid conditions along the eastern seaboard of the US and Canada, as well as arctic conditions in England and Europe.

Perhaps I did not make myself clear.
Consider the situation where you have liquid water and dissolved solids in combination giving you a certain concentration. Now remove some of the liquid by converting it to a solid form (icebergs). The only substance in the iceberg is pure water. This leaves less liquid water and the original amount of dissolved solids remaining - thus increasing the density of the water. So, easier to float in the Aritc vs. Atlantic.

A person would float more easily in the Artic Ocean. The Oceans ability to provide buoyancy is due to the amount of dissolved solids in it - like salt. Since the Artic Ocean is full of icebergs which are nothing more than fresh water ice cubes - that leaves less water and more dissolved solids in the Artic Ocean.
Easier to float in the Artic than the Atlantic.

Finally I looked at the NODC (national oceanographic data center) site. The Arctic Ocean has a surface salinity of between 30 and 32 % (varies with location), whereas the North Atlantic is more like 33%. Other parts of the oceans of the world go as high as 36%. This means my initial answer was correct. Amazing what is actually known about the world.

Actually I have been thinking about it some more. I hate to argue with myself, but if the Arctic ice floes come from the water freezing (not on land) you would be right. I think both things happen. Certainly the North Atlantic has ice bergs. Apparently, the Arctic Ocean freezes over (it used to) and there is no land right there.

Just curious, why would one float differently in different oceans? Water is water, or am I wrong? I have never heard this....
Would it be from different wave sizes?
Now you got me thinking......
I would rather 'float' in the Atlantic, I have never been to the Arctic, that is why I choose the Atlantic....

The icebergs do not come from water frozen out of the Arctic Ocean; they are produced by great chunks of glaciers falling into the ocean. And the glaciers originally derived from snow falling onto land. So the icebergs do not change the saline concentration until they melt.

Icebergs are frozen water but since they are not dissolved they do not change the salinity of the Arctic Ocean. I think your logic is flawed.
