Indian Ocean is 100 meters lower than surrounding seas

Giant 'Gravity Hole' in the Ocean May Be the Ghost of an Ancient Sea

A vast expanse of the Indian Ocean is a staggering 100 meters lower than the global average sea level because of a major dip in Earth’s gravity. Scientists now think they know the cause

So even "sea level" isn't the same everywhere due to gravity? I knew there were local differences but I didn't think gravity was the cause. 106 meters is a lot of volume.

Maybe that's why Biden chose it for his first trans-oceanic train.

So how much will Kerry & Co. say he needs to combat changing sea level caused by Gravity-Flux?

I hope they don't try to blame it on global warming.

That sounds like bullshit too. So if Micheal Moore goes to India and loses weight it's not because there are no cheese burgers?

Oh, they'll find a way.

They will blame America....

Somehow.

It just has to be capitalism and the 2nd Amendment.

Not intuitive.

You'd think that if the gravity were lower there, the water would be higher due to less downward pull.

Let's ask westwall

You are correct. Gravity anomalies are all over the Earth. So I find it amusing these people get all hot and bothered over something that is barely measurable.

 

[Oddball]

That is correct. Gravity anomalies are all over the Earth.

OK....I knew that....Nearly nothing around the planet is equal....That's why rockets launched nearer the equator have an easier time getting into orbit.

But why would the water level be lower, with less gravitational pull?

Let's ask westwall

I read this on the subject:

In simplified terms, mass concentration (which increases gravity locally) "pulls in" water from the surrounding sea, raising the water level.

Essentially, a large mass will cause "down" to be bent slightly toward it, and water from the surrounding sea will flow "down" toward the mass concentration. The resulting surface of the water will (ignoring currents, wind, etc) will form a bulge above/around the concentration which at every point is perpendicular to the local "down."

If an area of lower density results in lower gravity, the effect will be the opposite, with down being bent AWAY from the center of the area and water flowing out until the surface is perpendicular to the local direction of gravity. If it helps, consider the lower gravity to simply be surrounded by a ring of higher gravity areas which all tend to pull the water away from the center.

Note that this effect is VERY small and won't be noticeable to an individual - it is only when the effect takes place over hundreds or thousands of miles that the tiny change in gravity results in a detectable change in water levels. It won't make a noticeable change in the horizon, etc., and any differences in actual acceleration due to gravity would need very precise and sensitive instruments to measure and separate from other effects (such as actual distance from the center of the Earth and latitude) which affect the apparent acceleration due to gravity.

Extremely interesting....thx...

Maybe after the bed wetters decided to lower the bar for stupidity, and sent it crashing straight down through the core of the earth, blasting out from under the Indian ocean and out into space, the water filled the exit wound?


It's more plausible than global warming due to America's SUVs anyway.

 

[whitehall]

Wouldn't common sense tell you that the water level is pushed down because of an increase in gravity (if that's possible) rather than less gravity?

Bed wetter's have no sense, common or otherwise. "Journalists" will print any lie, no matter how ridiculous knowing someone will buy it.

What they are claiming is because of the density increase water piles on on top of itself. Whiiiiich is not measurable. The problem they have is the oceans aren't closed systems, so water comes in...........and immediately goes away.

Now, if you had a body of water that was fed by rivers, but had no outflow, like the Great Basin in Nevada, or the Great Salt Lake, then they might have something.

That's the problem you have when you are trying to measure something so vanishingly small.

If you take it at face value, though, then you'd think that there'd be some sort of outflow current somewhere, wouldn't you?

Yes, according to their theory the only place the water can go is down, so I would expect to see some extensive scouring on the sea floor.

I don't see evidence for that anywhere.
