This movie contains 33 potentially triggering events.
They kill the dog. We don't see or hear it - it is implied. One crew member reports to the captain that the dog is missing. The captain says he'll come back when he's hungry. In the next episode, they have a bag of meat and say "it's not a man, but it belonged to one". It's obviously the missing dog and it was killed. Emotionally it's upsetting, but as far as viewing, it's all perspective and assumption - we never see harm. The dialogue is the painful part because of what it tells us.
There is an illness affecting some crew members and a ship's doctor uses a monkey to figure out what it is. So he deliberately poisons the monkey and it dies.
(Episode 6) a character sets himself on fire, his burning body is shown, as is his faced after the fire is extinguished. All the characters are stuck in a fire, and there is mass panic. (a few characters catching fire is shown, but it is brief). It’s said later that several burned alive but you only see their bodies very briefly after the fact.
Several characters get scurvy, which leads to their gums bleeding and their teeth falling out (one chardcter pulls his tooth out at the start of episode 9).
In the last episode of season one a crew member drinks poison and then cuts their own wrists and it is all shown on screen including the moment he dies.
That's a thing I can solidly say about "The Terror," is that they do an absolutely brilliant job of making it perfectly clear that the Inuit are by and far the most sane characters in this entire show. There is racism, and there is outdated terminology, but it's due to the time setting and the characters' own beliefs, the latter of which are always shown to be overblown and misplaced.
Many instances of Inuk/Indigenous people being called slurs. Some characters express disgust at having to be near them. There is a deliberate and malicious decision to disregard Inuk custom when burying an Inuk man's body, despite one of the crew members insisting they honor him according to his peoples' custom. However there are some characters that are respectful.
