Magnetic field—of the oceans!

Wow, incredible—and great for tracking movement of water in the oceans.

The researchers chose to focus on the oceans because they make a tiny, but important contribution to the Earth's overall magnetic field. The salt within seawater can conduct electricity. And oceans don't remain still; rather, they move in cycles, up and down. As the tides cycle through the world's oceans, that salty water essentially tugs on the magnetic field above our planet.

"We have used Swarm to measure the magnetic signals of tides from the ocean surface to the seabed, which gives us a truly global picture of how the ocean flows at all depths — and this is new," Nils Olsen, the head of geomagnetism at the Technical University of Denmark, said in a statement.

The magnetic field generated by the oceans is quite small. "It's about 2 [to] 2.5 nanotesla at satellite altitude, which is about 20,000 times weaker than the Earth's global magnetic field," Olsen told BBC News.

The newly analyzed data will give researchers a more nuanced view of how the oceans are affected by climate change, Olsen noted. "Since oceans absorb heat from the air, tracking how this heat is being distributed and stored, particularly at depth, is important for understanding our changing climate," Olsen said in the statement.

Birds and sea life use the oceans and cores magnetic systems to navigate and understand weather patterns. On land many animals do the same, but use just the core. When you live with the land and not against it, you can see and appreciate how natures life forms coordinate their lives with nature.

When I look out at the southern ocean, you can see it in action. When there was a big storm looming, our bay used to get filled with birds a day or so before it arrived, they already knew what side of the bay to shelter. Looking down on the bay, it was a sea of white. Now instead of thousands of birds, we get less than 100. To me this is a very disturbing sign, it means sea life is dying out, because there is no longer enough food in the oceans to feed its life forms. Humans haver ravaged the oceans to the point of killing its life force.

Oxygen content of the oceans is shrinking too.

We have been very bad stewards of our planet.

Sure is and plastic contamination is growing. The majority of the humans race don't care, as long as they can fill their faces create waste get their kicks out of the most bizarre and useless endevours, nothing will change. It's painfully obvious we have destroyed any future for the majority of life on the planet, it's just a matter of what living beings survive ideological humanities war against everything..

Not many species shit in their own nest. We are one that does.

HOPE?

what hope is there?
Nope.. we've done a bang-up job....

a divine gift?

look how we've all shat on that.

so even when humans believed en masse they were the children of God, they still shat on everything they were given.

Hey, I think I'm an alien.
