is it fresh water I wonder?

  I think this is a definitional thing. If it’s made of salt water, that’s called sea ice which is formed when water just freezes on the surface of the ocean. An iceberg on the other hand is a broken off piece of glacier, which is ultimately made of snowfall, and therefore should always be freshwater (at least on earth!)

  Basically all ice is fresh water. Ice that forms from sea water (sea ice) will be composed of fresh water ice and pockets of salt water (brine) which generally drain themselves out reasonably quickly. Ice that comes from glaciation which I believe this iceberg is would just be fresh water from the start.
