Huh, this idea is new to me. Could you help out with a link? I only found two articles that talk about icebergs and gravity, one from NASA that only mentions taking measurements with a gravimeter [0] and a popsci article from 2011 [1] that mentions the geoid and irregular gravitational field of earth, but only sourced its “sister site” which appears defunct and simply redirected to its own front page, which looks like a garbage fire of pseudoscientific advertisement. I also found a BI article (to which I link with great trepidation) that mentions I think the same iceberg as the NASA article but mentions it is not expected to contribute to sea level rise in any significant way [2].

- sixstringtheory 7y agoAwesome, thank you! I’m now interested to try some back-of-the-envelope math to compare the mass of certain ice bodies to that of the moon, and the respective distances from moon to earth and, as the article mentions, Greenland to Scotland, and compare tidal differences induced by the moon, its squared inverse distance, and the gravitational effect of the ice on sea levels.
