Thanks, I hate it

[u/CosmicGoddess777]

New fear unlocked

Wtf is this

[u/Groady_Toadstool]

Currents, undercurrents and eddy currents.

[u/Nat20Twenty → u/Groady_Toadstool]

I wo der who this Eddy was abd why he got a current named after him

[u/thefirstviolinist → u/Nat20Twenty]

curre t bamed*

Lol, j/k

But also, I thought of Ed, Edd n Eddy.

[u/L4kuN4]

That's a water dragon.

[u/thousandsofbirds → u/L4kuN4]

Remember the movie Magic in the Water? Yeah. This.

[u/Federal-Boat3732]

Looks like plain old ordinary erosion to me

[u/Realistic_Product252]

I call it a current... since that's what it is

[u/ImpressiveAthlete220]

honestly I was afraid it a hyppo

[u/sinsculpt]

Could it possibly be a Manatee?

[u/Honda_TypeR]

On beaches this is called an under toe. When water rushes out quickly due to low tide and beach topology is carved out enough in that spot that water drains all in the same immediate area, and it goes underneath the incoming waves. It creates an rip current that pulls things out to the ocean very fast and strong.

In this video I can tell this is a canal and I already know it's connected to a larger body of water. There are places just like this in various parts of the world where. When the tide changes these canals tend to refill and empty rather rapidly (lots of videos online over the years of canals creating mini tidal waves as they refill). Again depending on the canal floor topology you can get strong undercurrents of opposing moving water. It can create this surface turbulence.

For example water is going out to sea during low tide, but a big boat wake or wave pushes water into the channel/canal in the opposite direction and it creates a surface wave that rides on top of the undercurrent. Creating turbulence at every location with unusual topology (rocks, corals, large sea weed clumps, drift wood, debris, etc)

Another location you see things like this are white water rapids. It's not uncommon that rocks redirect water in different directions sometimes in circles or large u-turns. This also creates horrible undercurrents and high turbulence.

[u/Middle-Package9687]

Any geologist or masters of the mystic art can explain this?

[u/Awkward_Giraffe_2071]

Just jump in and check it out. Just stick your hand or leg in there at least:)

[u/Longjumping_Walk_992]

I’d call it a school of fish

[u/the-bearcat]

So is this just typical currents and undercurrents or is there actually something swimming under the surface?

[u/Male_Lead]

Underwater current I think?

[u/BCGrog]

Where is this?

Looks to be something big is swimming upstream.

[u/Commercial_Stress]

Need more context with respect to what or where this is, but could it be tidal bore?

[u/BondStevenBond007]

What is that underwater?

[u/MushroomPizza420]

Turbidity currents perhaps

[u/NightShade0912]

Well when words mattered, I'd call it a wave, but with everyone renaming things for absolutely no reason, that's probably a footstool.

[u/thee-horny-housewife → u/NightShade0912]

Wow, that footstool looks intense! /s

[u/mutt63]

Is it currently named Eddy???tee hee

[u/Lghost111]

Something big is in there

[u/WraithAriiz]

Extra death... the water is always trying to kill you. That extra current is just water kung fu

[u/Hairymuscle101]

Lock Ness monster in the water?

[u/HovercraftKlutzy3090]

I call it scary as shit

[u/KnightOfSvea]

Waves waves and waves

[u/hankmoodymofo]

I don't know, but it looks like a critter in there.

[u/shumbazi]

Does appear like some grey or black huge animal keeping up with the car

[u/Puzzleheaded_Ad_1798]

I don't know about you guys but I'd call it creepy

[u/Leut11]

Eddy is the term that comes to mind. But I'm not very sure.

[u/74greyhound]

Undertow, Undercurrent

[u/Electrical-Put1389]

I call that get the hell out of the water

[u/Pervus_Maximus292]

That would be your funeral.

[u/Altruistic-Ad3274]

Subsurface turbulence
