Lena Delta – Magnetic lines of force?


This article claims these, or at least many of them, are caused by methane emissions resulting from warming 40,000 years ago.”

“Here’s some stuff I dug up, with a wonderful picture of what looks like a giant sieve.

“Does that time frame match up with what you postulate? i.e., could they be related phenomena (to the Carolina Bays)?”

“Also, I think it’s interesting that they are so highly ordered, which would make sense if some magnetic phenomena were involved (I’m thinking ‘lines of force’ sort of thing here).

“The search terms I used to find that, and the links below, were either…72° 9’3.54″N, 142°10’26.31″E …or “Lena Delta.”

“Here’s a shot of the whole thing.  Sure is pretty.  …from this NASA link.”

Thanks, Yonaton. I think you’re onto something here. Lines of force make more sense to me than “methane emissions.” And yes, this dates generally to the Laschamp magnetic reversal.

But did you notice how they had the nerve to add the words, “Nowadays, additional methane and carbon dioxide are artificially emitted into the atmosphere by human activities and are the main driver of the observed climate warming.“

The main driver? Just where do they think that previous warming of 40,000 years ago came from? The Neanderthals?

I’m guessing that there weren’t many farmers in Kansas back then driving those dastardly tractors and combines and belching huge amounts of CO2 into the sky.

How dumb do they think we are?

Robert – I think those Polygon lakes are typical of high latitude tundra landscapes.  The polygons form from hard frost/freeze in the relatively soft ground and mire of the delta deposits. Similar to “ice wedging.”  There are also polygon lakes near Kamloops, B.C.Another possible cause of these ‘polygon ponds’ and also the ‘Carolina Bays’ is quite a simple explanation called  Glacial Kettles. Where a single block or in these cases, many blocks of ice, trapped within the till of a glacier and when the climate warms and glaciation ends, many depressions are left over, which fill with groundwater.  In addition, the melting of vast sheets of ice further inland will carry large amounts of sediments over the relatively flat outwash plains- I’m thinking here of flooding over the top of large area glacial ice sheets- put it all together with the 1000’s of years of ice-age climate variability and you get these ‘bays’ and semi-regularly spaced small lakes and ponds.

That is why there are so many little lakes the farther up in Canada you go.  Glacial Kettles!

The following comes from “Geology Illustrated”, by John S. Shelton  (Formerly Associate Professor of Geology, Pomona College) Copyright 1966, Library of Congress Catalog Card Number 66-16380.

on page 224, under the heading “Evidence of an Ice Age IV: Extensive Pitted Outwash Plains”:

‘The depressions cannot be craters from a meteorite shower because they show neither explosive disruption of the bedding nor rims of material thrown out of the holes.

Great numbers of depressions in a thin deposit of loose stream laid sand and gravel are characteristic only of kettles in glacial outwash.  Such a pock-marked blanket of meltwater deposits is often referred to as a pitted outwash plain. Geologically, it is an almost unique combination of features and very good evidence of former glaciation.’

It is my opinion that what look to be ‘lines of force’ were merely caused by the wide and shallow flow of glacial meltwater over a relatively flat and perhaps somewhat sloping surface – curving is similar to meanders in a river which only happen on planar surfaces. These landscapes did not form overnight and are doubtfully affected by magnetism or electrical effects.

There are also kettle lakes on Cape Cod, Ma. also a former outwash plain.

The “Bays” of the Carolinas are probably much older that what is seen in arctic regions (Lena), when the north pole was down near the Great Lakes, N.A.

PS: Looks like we’re in for a COLD Winter this year! Many Geese & Ducks have already gone South, other years Ive seen them flying south even into late November/December, but this year I don’t expect to see many migrating as late as I’ve seen in previous years.

Are you sure about the picture of the magnetic grid thing? It looks pretty much like a dish cloth with a blue cleaning fluid to me. Is someone having you on? It ain’t me in case you ask.

Brendan

Nope. You can actually see the pattern
when you go to Google Earth.
