i so much like this video , this video deals with my project work which is the dynamo theory of the earths interior and also my current project which is variation of earths magnetic field with latitudte and longitude...i would love to have this video for some research purposes

good info... be confident ... leave out
umm and your own doubt

A good observer would notice the s-curve path of the magnetic field as it moves from pole to pole. The magnetic field is moving along a double torus model.

Does the ocean have a stronger magnetic density/field than would a random point on land?

This is a very informative presentation. Thanks UCTV for posting it here.
This video is linked on page 28 in the Sun Earth Connections thread at Sapo's Joint (.net).

There are a few things they still don't consider: earth expansion (some contraction) and relative rotation of the continents on that sphere as it expands. The so-called tectonic plates were at one time layered on top of each other at one time in various places. It's amazing. Therefore applying field orientations based on current 'plate' orientations won't give reliable results. Factoring in earth expansion, produces far fewer geomagnetic reversals with reversals being sudden and catastrophic.

One might try overlaying the record of reversals with saturn's rings. The Cassini division might be the cretaceous quiescence.

I'm wondering if magnetic field reversals could have occurred on Saturn and played a role in producing its rings. The rings look a bit like the record of the magnetic reversals you show.

Awesome.
