When the surface of the ocean is seen just outside the base in a preview video, it doesn't seem that dark, almost like a twilight-ish on the surface. ASSUMING that it's currently daytime in the surface, I would place my guess of the base in the Mesopelagic part of the sea. The Mesopelagic has a twilight-ish color with the depth of 200 - 1000 m. Using equation of the pressure increase, we know that it has the pressure of 20 - 100 atmospheric pressure which doesn't sound that bad.

However, if it's currently night time in the surface, then I would place my bet on the Epipelagic part of the sea, with the depth of 0 - 200 m, with the pressure of 1 - 20 atmospheric pressure which makes it more habitable.

This post has great merit when we consider other clues in the video. Firstly, we don't see any of the typical marine life of the Abyssal or Hadal zones. Secondly, we see small fish which are typical of much shallower zones.

Thirdly, we see a small crab of the kind found in shallower waters, nowhere near the Abyssal zone.

Fourthly, and very importantly, we see a hammerhead shark, barnacles, and common bivalve mollusks (not the giant mollusks found at Abyssal depths).

Spoiler below!

None of these are found anywhere near the Abyssal zone; barnacles are only found down to 600 metres, and while one type of hammerhead is found down to 500 metres, another type is found only down to 80 metres.

If the plot is true to these details, we can reliably place the undersea station within the shallow regions of the Mesopelagic zone at deepest, and more likely in the deepest part of the Epipelagic zone.
