THE OCEAN FLOOR IS SINKING UNDER THE WATER WEIGHT FROM MELTING GLACIERS, AND IT’S AS BAD AS IT SOUNDS

THE OCEAN

So much extra water is being added to the world’s oceans from melting glaciers that the ocean floor is sinking underneath the increasing weight. This ocean floor deformation also means we have miscalculated just how much ocean levels are rising, and the problem could be far worse than previously believed.

Over the past 20 years, ocean basins have sunk an average of 0.004 inches per year. This means that the ocean is 0.08 inches deeper than it was two decades ago. While this small fragment of an inch may not seem much, oceans cover 70 percent of our planet, making the problem bigger than it seems at first glance.


In a study published online in Geophysical Research Levels, researchers explain how they used a mathematical equation known as the elastic sea level equation to more accurately measure the ocean floor. This allowed them to see how much the bottom of the ocean floor has changed from 1993 to 2014. While they are not the first scientists to look at the ocean floor, this is the first time that researchers have taken into account how additional water from melted ice may have further stretched that floor, LiveScience reported.


The results show that the ocean is changing in ways we didn't realize and is sinking further into the earth’s crust. As a result, scientists have underestimated how much sea levels are rising by as much as 8 percent. The study concludes by emphasizing that future sea level measurement should take ocean floor deformation into account in order to more accurately understand how our oceans are evolving.


All the water on the planet today is all the water that has ever existed on the planet, but not all water is in its liquid form. Recently, rising temperatures have caused much of the frozen water on the planet’s glaciers to melt and join the ocean as liquid. This mass melting of ice has raised sea levels, a problem whose consequences we’re already starting to see. The first people to notice the repercussions of rising sea levels are those who live in coastal areas. Rising waters mean less land to live on. In addition, more water in the ocean means that ocean storms, such as hurricanes, have the potential to be stronger and more devastating, National Geographic reported.

Small coastal areas won’t be the only ones to disappear due to rising waters, and if current estimates are correct, by 2100 the ocean will rise between 11 and 38 inches, a number that could mean that much of the U.S. east coast will be covered in water, National Geographic reported.

Good grief, the insanity will never end. I wish they had a cure for libtard.

How can they even measure 8/10 of an inch. The ocean is never calm level in EVERY spot to measure. What they use to measure if it was shot off of alandmark. A laser that is accurate at over 6,000 ft
. Wonder how much tax money they wasted on this crap.

They talk about coastline disappearing. If the idiots would stop building their mansions on a cliff !! I watch the news at some one crying as their house slips into the ocean . I feel sorry for just a minute then I realize what an idiot. You built it hanging off of a cliff what you expect.

GOD is not happy with California.. All I'm going to say............................. watch the news

That's 8/100 of an inch

It is hysterical. I keep waiting for them to start popping like corn or start jumping off cliffs into the ocean like lemmings.

Does their measurements take in to consideration the rise in ocean ridges. Or the normal rise of terrestrial mountain ranges from the slide of the crust ect ect ect

Not likley, they just need to find something that the useful idiots will eat up

.004" is roughly equivalent to the thickness of a standard sheet of notebook paper...

A human hair is approximately half that thickness at around .002"

I'm having a hard time believing that they're able to accurately measure measure that small a change. Especially over millions of square miles that is constantly sloshing and getting pulled back and forth across the planet by the moon.

Anyway...

Heracleion was inundated long before man-made climate change was a thing. So apparently oceans tend to rise from time to time.

The biggest issue about the melting of glacier ice is the subsequent introduction of dihydrous oxide into the environment. It is responsible for thousands of deaths and millions of dollars in insurance claims each year. Here is a short list of the dangers of dihydrous oxide.
*it is the most universal solvent known.
*corrodes metal
*causes brakes to fail
*causes respratory distress
*distroys wood
*excessive amouts causes root rot in crops
*ruins electronics
*causes electrical shorts
*destroys your homes foundation
*causes damgage to roads

Lol. Good one.

Could it be the measurement taken in 1993, while no doubt using the most analytical equipment then, may not have been as accurate as the equipment used in 2014, and the difference is only precision?

we discussed this in depth yesterday morning - I could not find in the calculations the increased evaporation rates of all the water that was freed from the glacial ice. Also would not the liquid water have gravitational pull down into the voids of the sunken floor and thus reduce sea level.....we had a great time coming up with definitive arguments and thought we should publish all our ideas as well.....but then we got back to work.......ahh I love reading todays science showing how you can "prove" anything with a few thoughts

for those that cant picture it - fill a cup with water and mark the level......next drill a hole in the bottom simulating the sunken floor.....now record the level of water - did it rise?

I can easily accept that the sea floor is being depressed by the weight of water. We know that today's land features are still rebounding from the weight of Pleistocene glaciers. If isostatic equilibrium works above water, why would it not work under water ?

We know that ice weighs less per cubic foot than does a cubic foot of water. And that the weight of water increases as temperature decreases; then 5 mile deep water weighs a lot more than 5 mile deep ice.

I do have to question the accuracy of the measurement.

It reminds me of the old adage.....The more precise the statistic, the bigger the lie.

how can ice which is formed at colder temperatures weigh less than water AND weight of water increase with falling temperatures.....

Ice contains air

For every action there is an equal and opposite reaction, they say.
If you collapse part of our earthly sphere, the core has to give. Would not there be a very large uptick in volcanos if 70 plus percent of the sphere were collapsing in on itself?

mass needs to be taken into account - more energy is utilized in warmer water and thus can be more dense - but then you also will have more evaporation with warmer water as compared to sublimation from ice

Consider that when water freezes it expands...unlike almost everything else that contracts. So if you take a cubic foot of water and freeze it, it now occupies more than a cubic foot. So.......1 cubic foot of ice weighs 57.2 pounds whereas water...at 70 degrees weighs 62.3 pounds.

As the water gets deeper ....say in the ocean....it's temperature decreases, as does it's volume. It contracts. Therefore, the density of the cubic foot of water increases...Higher weight per cubic foot as temperature decreases. That's why the pressure at the seabed is so much greater than at the surface

Something has to replace the voids left from pumping oil and gas from the earth???
