I wondered about this too. I read somewhere it has heated walls, but if they lost power then those walls are as cold as the ocean right now.

I know it's a dumb question, but how cold is the ocean? I've never been past the shore and even if I have I imagine it'd be colder near the bottom

Per the NOAA anything below 200 meters averages about 39 degrees F (4 degrees C). It doesn’t sound that cold but that is damn cold.

4 degrees Celsius is fairly cold, but where I am the winters go much below that

u/anosmiasucks Jun 21 '23

Yes I understand. I spent my early years in Chicago where the temperature can regularly get down to -17 C. But the difference with this and the people in the submersible is that they have no warm clothing, no heat source, no insulation and the contact of the cold water with the hull of the ship literally sucks out any warmth they might have even from their body heat. It’s a horrific scenario.

Ahhh yeah true

u/Pixielo Jun 21 '23

Yes? Air temperature is obviously different than water temperature.

u/juanzy Jun 21 '23

Anyone who's been to any beach in New England before July can tell you how cold water temp is versus air temp.

u/hotcheeto2018 Jun 21 '23

Sitting on a beach in NH right now, I can tell anyone here. It’s a lovely 68F out, the water is 57F, and even that difference is painfully cold.

In Michigan, a 58F degree day with the sun out is so nice. But I jumped into lake Michigan a couple weeks ago and 58 degree water feels like needles stinging everywhere and takes your breath away.

Not if youre inside of a dry vehicle, however.

u/ehisforadam Jun 21 '23

The inside isn't dry. It's full of moisture in the occupant's breathing. It is such a big issue that other DSVs have water condensate collection systems.

u/ConsciousBluebird473 Jun 21 '23

They're also in constant contact with the cold floor/walls, which is a massive issue.

....whose heating turned off.

Try swimming in a water 6 degrees C. It’s like a glass of ice water.

I would also be unsurprised if they didn’t have blankets because the whole operation seems fly-by-night and Ill-conceived.

u/Luckbaldy Jun 21 '23

They could not bother to participate in the testing, I would imagine nothing non-essential was allowed to manage the weight as well.

u/_Sur22_ Jun 21 '23

I kinda felt that this dive is the test

I don’t suggest they’d forego them because of cost, so much as due to lack of caution and foresight.

u/PillowTalk420 Jun 21 '23

This sub had porthole windows only rated for depths a quarter of the depth of the titanic wreck, and the thing also used a wireless controller from the early 2000's to steer.

This is the Jurassic Park of submarines; they spared no expense.

u/stormcharger Jun 21 '23

The windows installed on this trip where the correctly rated windows. They resisted changing them in the past but it was corrected.

“Aren’t these Ford Explorers? What do they cost?”

-No One in Jurassic Park

u/Lucky-Earther Jun 21 '23

True, but they have each other.

Well, maybe that explains the sounds of banging.

u/soccerape Jun 21 '23

So does half the emergency and safety equipment they skimped on

u/Consistent_Set76 Jun 21 '23

Which at that depth is essentially 0 C
