Icebergs are generaly formed from glacier breakoff so are freshwater in any case. They only make up a tiny minority of sea ice.

As has been said, when seawater freezes, it rejects the salt content and is almost entirely fresh. This leaves high salinity water below, which sinks and helps drive the halothermal (or themohaline?) ocean currents.

Yes... they were commonly used as a source of fresh water by sailors in the high arctic or antarctic.

Wow. So icebergs prove the Bible is true. Ain't that a kick in the head!

No no no... rather, the Bible doesn't mention icebergs, therefor icebergs don't really exist! (After all, have you ever actually seen an iceberg with your own eyes? Who are you going to believe... atheistic scientists, or the Bible?)

Yes, I know that rains are purported to have caused the flood, so waters high enough to cover the earth would have greatly reduced salinity - but it would still be there.

(I know glaciers are specifically formed from snow accumulation, so I apologize if my terminology is a little off.)

I am assuming that you are talking about the only time the earth was ever flooded [ie. the "Noah account"]. FIRST of all, where in the Biblical account, or ANY account for that matter did it say that the waters that rose FROZE??? The fact of the matter is, the waters did not freeze, unless I missed reading something of course. SECOND of all, has it occured to you that salt water does not freeze??!!

Matter of fact, the salt content of the Greenland ice cores is measured in parts per billion, where the salt content of seawater is almost 3%. You really wouldn't have to submerge your somewhat-porous snowfiels in seawater too long to get that old salt level at least up into the parts per million. (And the newest core up there goes back 130,000 years.)

Then why spend all that money on desalinization plants? Wouldn't it be easier to just build a big freezer and pump the seawater into it? (that is, a thin freezer...)

Well, nowhere - but what do you think water does in regions on Earth were the temperature is much below 0 degree (Celsius)?
Or do you want to claim that the Earth was much warmer at the poles during the flood (which never happened, BTW)?

Interesting. I don't know in which world do you live, but in my world it does. If you don't believe it, try it yourself with your fridge.

You're maybe confused by the fact that salt water freezes some degrees lower than sweet water. Or you're simply repeating some crap from Hovind. I hope it's the former.

In point of fact he is right. Salt water does not actually freeze. It polymerizes. Only distilled water freezes.

Admittedly it looks and feels just like frozen salt water but under a microscope it is identical, hence the confusion. I'm sure I read this somewhere. In the previous paragraph I think.
