Temperature oddity

[IEATDIRT]

Why can you dive into the freezing arctic water and heat up? when has jumping into glacier water heated a person up?

Pure water cannot get colder than 0 C (32 F). Air can get much much colder

Oh pls, jump in 0° Water and tell us afterwards how much you warmed up. pls

I'm going to assume that future dive suit tech had advanced enough that it can provide warmth in arctic waters, but the surface must be so absurdly cold (i.e. well colder than even Antarctic temps on Earth) that even that suit no longer provides protection.

This isn't really too much of a stretch, as we have 6mm fullsuits today that allow divers to swim in the arctic. By the time the game is set, the tech could have improved.

Just a reminder of how much thermal activity secter zero has would explain everything

[procnessil]

Except the game shows temperatures. With water being 1 degree Celsius, and surface several degrees below 0. But the heat exchange with water is several times faster than with the air, so it should always be colder in the water. I assume devs thought the game would be too hard and annoying if you were freezing in the water.

It's one of those things thast don't make logical sense but are there for gameplay reasons

Have you never made ice? Storms and air do this thing where they move around, and ocean floors have thermal vents, especially in this game if you've ever played it

[Dynamiez]

I have played it. and i know if you jump in 0° cold water because of the better thermal conductivity og water you are dead in 2 minutes (without a dive suit ofcourse). within air? hmm, could survive very long. in real life its nearly the opposite of the system you encountet in this game

So unfrozen water is colder than air that is colder than the freezing point of water? Thats what you're saying? Plus the game planet has massive geothermal pockets that leak under the places where *gasp* life is thriving

[Dynamiez]

unfrozen water is not colder that maybe the air. and that is not even what i was saying.
look, if outside your house are -10° celsius, you took your jacket or perhaps only a nice sweater and are just fine... you can walk and be happy for hours and hours outside.

if you jump in 0° celsius water, even with a 8mm wetsuit. hmm... a few minutes perhaps? and this water in my example is 10° warmer then the air. that why ice divers wear mostly dry suits where youre skin dont have
direct contact with the water and a hoody and gloves are mandatory too. water is such a good heat conductor that even in 20° celsius water you wood freeze to death if you stay long enough

oh and you can see clearly in the game that robin is not even wearing a dry suit, else she would look like marshmallow man

[TheGraveDigger]

Let’s just say

Video games are NOT designed around realism and never should be

[IEATDIRT]

maybe the water has an extreme salt content

Well below zero water is salt water (there is also lots of salt deposits in the game)

Short answer - yes.
Long answer - what your body is feeling as "cold" is not the temperature itself but rather how quickly the body is losing heat, or to be more precise, how quickly your skin gets colder. Bigger temperature difference (lower exterior temperature) is only one of the factors in this process. The other factors are, for example, specific heat density (SHC - how much energy is needed to heat the substance by 1 degree) of the substance that your skin is touching and its density and heat conductivity, although that boils down to how often the substance particles touch your skin, and "steal" heat from it.

When you compare water and air you will see that air has lower SHC than water, which means a particle of air will take away less energy from your skin when they collide. Also, water has way more particles packed together so they will hit your body much more often than air.

Fun fact - if due to some accident you fall in cold water, have a life jacket, and are waiting for the rescue, then you should wrap your hands around your body, keep legs together, curl up as much as you can, and avoid moving if possible. All this to minimise heat exchange with water, because at this temperature no amount of movement will generate enough heat to offset its loss.

as well as moving water doesn't freeze as easily so it can be colder than 0 if the water moves regularly

But its not colder than zero, it warms you up, because the specific area the game is limited to is full of thermal activity from underground volcanic chambers etc. And the air outside the ocean is colder because there are regions of the planet that have less volcanic release and are basically solid ice berg rather than melting ice berg we explore in game, and the wind blows from those regions and tries to kill us.
