How do the layers of the ocean mix together? The energy put in by the winds and tides is less than what’s required for the amount of mixing, so what else is bringing the mixing energy? Turns out, it might be very active anchovy reproduction.

Let's not forget that there IS a significant source of heat energy at the bottom of the ocean - geothermal vents. I'm going to give the benefit of the doubt and assume that this was taken into account in modeling because it seems too obvious to miss.

@LuisAldamiz 25 күн бұрын

Not where the data was collected. Geothermal vents are in the mid-Atlantic Ocean ridge, i.e. between Iceland and Azores, not so close to the coasts.

@WrenStuart-y9h 25 күн бұрын

There are plenty of people taking thermal vents into account, but iirc they're not a significant source of mixing globally (I would guess just because there aren't enough of them, not quite my area). It's actually been proven since Sandström that you don't need the heat source to be below the cooling to achieve convection anyway

@backpacker3421 25 күн бұрын

@@LuisAldamiz Google "map of geothermal undersea vents for the fastest proof of how wrong you are. Not to be a tool, but that was just very wrong. They are literally everywhere there is a fault line at sea, which is all around the world, and MANY of them are quite close to shore.

@backpacker3421 25 күн бұрын

@@WrenStuart-y9h There are over 500 KNOWN vent fields, each with many many vents spread over hundreds of miles. But they absolutely ARE a significant convection source anywhere they are. Most of them were discovered because of the large plume of warm water they sent toward the surface. Can you cite a source that says they are not a significant source of mixing? Not my field either, but that is truly counterintuitive. If you've ever seen one in action in person, just one vent in a field can be sending tens of thousands of gallons a minute from the floor to the surface...... but that's less significant than fish swimming up and down a few meters at a time?

As someone who used to get punched in the head a lot for some extra spending cash, I feel like chins are an easy solve, namely, we have them to protect the teeth and mouth, same reason our cheeks are fatty and poofy, and the eye orbital and other parts of the skull extend out over where the teeth are placed. Makes it so it's basically impossible for an adult human fist and similar sized objects to connect directly with our very sensitive and irreplaceable teeth so long as the mouth is closed.

It seems to me that every creature in the ocean would help to do the mixing, with some doing more work than others. The ocean has a lot of thermal vents that create the convection from the bottom that helps to mix things. The salt content may also be a factor for mixing things, different densities different movement. All in all I think its the entire biodiversity of the ocean along with tectonic shifts under it and of course the tides that gives us our beautiful oceans instead of giant lakes of stagnant water. And that, my friends, is a very good thing!

my theory on chins is just our teeth being so sunken into our face but the rest of the face did not keep up, sort of like our nose is part of a muzzle that did not get shorter in length and just had to curve along being pulled by our jaws inwards, there is no reason to really evolve away a chin so it stays there its also as a expressive and acts as more protection for our teeth it takes the hit, it also makes beards look bigger due to the curved surface angle

I imagine that's gotta send some energy into the water that causes churn. I'm not saying the anchoveys don't help, I'm just surprised that in looking for the cause of motion for a large mass of water, we don't look at the proverbial container its sitting in and what forces its contributing from below.

Fish are efficient swimmers, they don't want to affect the water much, they want to use as little energy as possible to move through it. Look up "salt oscillator". Quite a lot of mixing is due to salt, which is very important as Greenland melts and makes the water more fresh, it's messing with the mixing. Also marine snow might drive some convection

@LuisAldamiz 25 күн бұрын

But they can't help it: water is a very dense material which has to be displaced (as efficiently as possible but still needs displacement) as you (or your pet anchovy) swims.
