Timeline for Why aren't "Bottom" and "Distance to deep water" the same in this context?

| Mar 18 at 18:14 | comment | added | JimmyJames | I would expect 'deep water' to mean: beyond the continental shelf. | |
| Mar 18 at 18:13 | comment | added | James K | But in your answer, you say the bottom of the sea is 72 metres under the ocean surface. Unless you happen to know the technical language (I don't) you can't be sure. But it doesn't really matter, it's just a movie | |
| Mar 18 at 16:39 | comment | added | Lambie | The sea bottom is 72 meters below where the sub is. | |
| Mar 18 at 13:06 | comment | added | Chris H | @IMil yes, and the underside of sea ice isn't particularly flat. A submarine might be concerned with the thickest bits (apparently called "keels", the underwater part of ridges) while a climate scientist might be concerned with the average thickness or something like that | |
| Mar 18 at 4:40 | comment | added | IMil | The ice may be a bit thinner. Depth is measured to the keel (bottom of the submarine), but clearance to the ice means distance from the submarine top. OTOH, ice floats, so not all of its thickness is underwater, only 87%. But you probably need to include a bit of safety margin to the clearance, to not scrape the ice by accident. All in all, could mean 10-15m of ice. | |
| Mar 18 at 3:15 | comment | added | James K | Do you know if the sea is 72, or 112 metres deep? I don't | |
