Exploring Extremes of Earth's Magnetic Field - Perspectives on Ocean Science

The Earth's magnetic field varies on many time scales, waxing and waning in strength, and periodically completely reversing direction. The geologic record of these variations provides important information on the history of our planet. Join Scripps Oceanography geoscientist Jeff Gee for a fascinating glimpse into his fieldwork in paleomagnetism -- from autonomous aircraft measurements over the open ocean to exploration of rock exposures in remote regions of Antarctica.

Very interesting! That green line of magnetic declination goes right through the Bermuda triangle.

[@BrownusGirl]

This was very well done! Appreciate the efforts to trim the questions down to the core and keep the talk under an hour (that was very well spent!)

[@marilynadams349]

Thank you for dedicated researchers

[@rebeccagrrrl2699]

Fantastic and fabulous!

[@per2]

great prsentation and great questions at the end

[@ronniepirtlejr2606]

This evidence is incredible. I believe it happens a little quicker than the millions of years you say!

[@PrepperStateofMind]

We have 13 months before it reaches the 40 degree mark. The acceleration will be stunning, but what will happen will be more eye opening.

[@beckyworley6751]

What do u think 🤔 will happen

[@michaelsullivan8057]

A magnetic field reversal will also induce a geological pole shift, unlocking the crust from the mantle and allowing it to slide over the earth in a snap-like motion. Ever wonder how we've found flash-frozen wooly mammoths so well preserved we could identify their diet by what remained in their stomachs?

[@daviddroescher]

Would a core sample from the Central Washington Basalt Filds (4mi/6.4k thick) share a similar data set and shed more light on the subject?

[@zapfanzapfan]

The magnetic north pole is moving rather rapidly and has sped up. Maybe pole reversal is under way.

[@gavinchurch6109]

It’s not maybe it’s gone to Russia

[@JMDinOKC]

Going to raise hell with our technological civilization.

[@resulsanane4506]

Check diehold foundation

[@tombaja4.9]

It's headed to Al's igloo. 🕳️🐧

[@brent9516]

Pole reversal due end of Feb. It could be an E.L.E.

[@janellehoney-badger6525]

The drones would make that deep sea tracking, done by those catapult planes, a hell of a lot easier.

[@rebeccagrrrl2699]

I wondered that too, then had the question wondering if the electronics on the drone would affect the readings? They had GPS on the catapult plane, so …. I just have more questions!

[@nickauclair1477]

Less boring than expected. Great presentation.

[@ammonbradford92]

The Earth is vulnerable to a polar flip every time the electromagnetic tension between the Earth's core and the Sun induces our electromagnetic field.

[@marilynadams349]

Very cool

[@andrewarmstrong8651]

The question is if we are so dependent for life through the magnetic field created by the molton iron core ,how did we get to the moon & back with no shielding but for a thin aluminium hull. Space is deadly or it is not?????????

[@garyhillman4993]

We didn’t is the answer

[@rebeccagrrrl2699]

Well, if we were to explore this would we ask about all things that are traveling outside the magnetic earth field? I don’t know the answer. Are there other things? Is the earths magnetic field surrounding the moon? You may already know the answers.

[@charleneconrado7564]

In reference to the chart @ 54:50 in this video, why is there no data for the Mediterranean Sea and other large bodies of water in this chart? Are we to assume there has been no research done in these areas or that there has been no or little activity there?

[@charleneconrado7564]

Notice how the attending audience is very mature in age!?

[@mikemalo6336]

@28:14, there is a before and after shot of McMurdo. there are sailing ship in the foreground of what is now exposed ground. does this show that the oceanic level has dropped 30 ft during 1910 to 2006? (based on the size of the human figure in yellow at the base of the 2006 shot and the hull/mast heights in the 1910 shot vs the corrected height of the peak to the right. Either way, with or without my OCD measurements just eyeballing it you can see the ships would be stranded here, well and truly fuct.)

[@-LightningRod-]

2021 NOW there is lightning in the Arctic

[@gnorman-ct2lt]

Your about to find out how fast a reversal can happen

[@overseachininadoll]

"We may be due for ONE"(Magnetic Field reversal) ...... Wow does that mean apocalyptic 2012 Dec 21? as Mayan calender predicted?

[@bobleclair5665]

It’s just the end of a cycle,,we are now entering into another cycle (the age of Aquarius). your bibles kind of correlate it too,,entering the house with the man currying the pitcher of water,,,time keeping has been going on for a long time,past civilizations were not necessarily all stoneagers,,check out,Milankovitch cycles,,think how that might effect the rotation of the earths inner liquid ,,the currents,the turbulence,the eddies,,.I think the earths poles will stay within a a few degrees of the wobble and return and begin again

[@tom-ke7lb]

according to this theory,an ice cube can stay solid in the center of a bubble of boiling water. how can the core stay solid if it is surrounded by molten (melted) iron?

[@paulnoon6892]

its there cause a current is running from sun through the planet, it isnt an iron core

[@mumbels24]

A must see for fans of ABC tv series Lost.

[@fuckby935]

mumbels24

[@MrKmanthie]

mumbels24 people who watch lame-brain junk like Lost would barely understand this stuff & their Twinkie-and-beer-fed attention spans would give out before the 1/2 way point!

[@ASheepNoMore]

magnetic north will hit the 40 degree mark this year 2023.

[@overseachininadoll]

I mean "the extreme Intense Magnetic reversal"

[@kimlarso]

[@marilynadams349]

And yet birds know how to migrate by the magnificent field. We humans are lesser in that brainpower?

[@audreye7078]

We stopped using it..

[@sandmanbub]

@ Whoop!

[@dr.omarayrad3583]

Ok, and the Earth is round,.... right..?,... OMG!

[@dwightehowell8179]

As the Maunder Minimum begins the solar wind is weakening. This means more gamma rays are hitting earth. Not sure what else is going on.

[@MrKmanthie]

Dwight E Howell How exactly does a weakened solar wind increase gamma rays hitting the earth? Especially when said rays come from the solar wind (among a fraction of distant sources which are much fewer & farther between). So many people who make comments on You Tube write things about which they know little to nothing. This merely shows the high level of ignorance on the part of many YT-ers.

[@daviddroescher]

As earth has a magnetic field protecting us from radiation of the star, a)the star has the same properties on the galactic scale b)as solor wind speed /volume/ CME's reduces during the reversal there is less matter is present to filter/absorb GCR( Galactic cosmic rays)in coming from our galaxy and behond. C) just as earth redirects solor particals/energy around the planet , so dose the start this effect is directly related to the magnetic field strength. Reduce the field and there is less redirection of FOR. Theas reversal periods are were we find the most evidence of new species showing up(GCR's damage DNA sometimes the damage causes changes that are actually positive such as changing scales to feathers .

[@normanhansen730]

What you say sounds fantastic, however, nobody has been there ( to the core with instruments, or lived in a time before the time of supposed pole switch. They can only gather data and propose some stretch of a theory. A study of the scriptures is truly forming a far different picture that can be backed by true science.

[@charleneconrado7564]

Why doesn’t mars have a magnetic field?

[@divinejustice536]

👍

[@marilynadams349]

Well I wanted the magnetic field big stour of earth that proceeded this

[@its_bob_from_accounting801]

so ,in theory , the barcode technology is ancient ...

[@rebeccagrrrl2699]

Poleshift march 2023 Boston mas 1220 Beware

[@bobleclair5665]

Where you’re talking a million years,,have you tried the math on plate tectonics or maybe the whole mantle is shifting instead of the inner core which probably has more inertia,

[@andrewarmstrong8651]

Bob Le Clair maths

[@goatamongsheep4296]

Models.....in other words = guesses.

i guess yer airplane is safe Ter Vax prbly is too

Earth axis out 30 degrees 2022

[@gzpo]

See electricuniverse.info and thunderbolts.info for true science - it's Electric!

[@MrKmanthie]

Gzpo You're an IDIOT! ! ! This whole "electric universe" & thunderbolts" thing is silly, pseudoscientific bullshit. You can't point to any mathematical equations, cannot cite any evidence because THERE IS NONE!!! Merely a desperate grasp at thin air for morons who aren't able to understand "grown-up" science & mathematics.

[@laural3738]

@@MrKmanthie Yes. Its well known that electricity and magnetism don't change the weight of objects so they clearly have nothing to do with gravity. The electric universe is not a scientific theory because it's devoid of any scientific basis. Otherwise there would be equations describing the acceleration of falling bodies and the movements of celestial bodies based only on Maxwell's equations of electromagnetism. And there would be also many experiments that would be essential to build and prove such a pretentious theory. Electric universe pseudo-scientists did not even produce a single formula in many years nor did they ever run any experiments to see if their absurd affirmations found some evidence in reality.

[@quantumcat7673]

EU is everything but science. You ought to check your sources and more importantly check what other experts think. Obviously, you did not.

[@bobleclair5665]

Be genteel Know Name,,don’t shoot the students,,the comment section helps us understand better,a better perspective

[@bobleclair5665]

There’s a lot of fishing in science,,new ideas waiting to be discovered,like math,,what came first,,the idea or the math?

[@charleneconrado7564]

Cartoon!? Don’t you mean illustration? It’s hard to take you seriously with such juvenile vocabulary.

Maybe because that’s the only word in his lecture you understand. He is brilliant and kind, and I’m fortunate to have him as a friend.
