The reason for measuring the ebb and flow of water levels is to better understand how the Earth's crust rises and falls due to the movements of the oceans. They liken Loch Ness to a carpenter's level. It is believed that Loch Ness tilts as Scotland bends to accomodate the ocean tides.
Scientists want to study other lakes around the world to understand this phenomenon. Britain rises and falls by centimeters every 12 hours and 25 minutes. The cause of this is a great bulge of ocean water surrounding the island nation. Loch Ness is inland but close enough to the North Sea to be affected by this loading effect.
The science team placed sensors a few meters below the surface of the loch. For 201 days they monitored the changes in height of the water over the sensors.
They found a clear spike in levels twice a day. Those correspond with gravitational pulls from the sun and the moon. They also found another signal that was the result of the land in the lake tilting.
I guess if we need to know if the Earth is level all we need to do is check with Loch Ness. That is until they start studying some of the other lakes around the world.
That's amazing! I find it strange that there are people who reckon there might be a gigantic beast in a lake we're using to measure how an entire country goes up and down. If Nessie was in there, we really would've found it before we spotted the entire loch tilting.ReplyDelete
Interesting idea. Maybe Nessie's undulating is causing the rise and fall? Thank you for stopping by.ReplyDelete
very interesting, I see that rise and fall on the lakes i fish all summer also.ReplyDelete
There you are. I hope they broaden the studies. This is an interesting concept. Thanks for stopping by.ReplyDelete
