The US extended its claims on the ocean floor by an area twice the size of California, securing rights to potentially resource-rich seabeds at a time when Washington is ramping up efforts to safeguard supplies of minerals key to future technologies.
There is a minor conflict between the US and Canada about the demarcation line north of Alaska. Canada argues that it should be an extension line going straight north from the Alaska Yukon border. While the US claims that the line should be perpendicular to the direction of the shoreline at the border. It creates a contested wedge. There's offshore oil and gas there -- which Canada is unlikely to develop (for environmental reasons), but the US may actually develop. On a global scale, it doesn't really matter, but every little bit matters right?
This extension will further extend this conflict. But in the grand scheme of Canada-US relations, it's still relatively minor.

It's cheaper to just split profits than going to war over it. And yes the US and Canada absolutely would in principle, the UK went to war with Iceland over cod -- because the UK thought that Iceland would just cave, which they didn't, they won the thing. Not everything needs to be high-intensity, cannot be, as war is the continuation of politics by different means and, as see above: It's often just preferable to agree instead of spending resources on fighting. Similarly India and China mutually agreed to forego guns in the Himalayas (among other things, risk of avalanches) and fight with sticks and stones. Dunno if I should count Canada and Denmark (as protector of Greenland) and their liqueur war over Hans' Island, they didn't even earnestly try to get each other drunk.
China’s claims are way more egregious. I’m not defending America’s claims but they’re at least plausibly based on the UN Convention on the Law of the Seas. They might not be winning legal arguments but they’re plausible enough to be legal arguments.
Some of China’s claims in the South China Sea are so far from the UNCLOS that I’m surprised Rudy Giuliani isn’t involved. Like, they sometimes claim the same rights as archipelago nations. China, you may have noticed, is not shaped like the Seychelles.
They also claim some islands based on arguments like “A Chinese guy saw that island first.” But that isn’t a thing. With all due respect to Zheng He (possibly the greatest mariner of all time), the UNCLOS isn’t based on who called dibs.
Most of this claim is perfectly reasonable. China is claiming international waters.
I do agree though that the claim around Alaska is way too large -- it looks a lot more like China's claim in the South China Sea. Take some small islands and claim the whole sea as yours.
Except those small islands near Alaska are natural, and have always been there, (On a human timescale, anyways) and were part of the original Alaska purchase. The one China uses to claim a whole sea was completely artificial, and built for the sole purpose of claiming new areas.
DSV is after the submarine went into space for some reason and came back? You wouldn't think a show about a submarine would have a season ending like that
