How the Arctic Ocean became saline

Researchers model climate changes caused by the submersion of the Greenland-Scotland Ridge

Date:June 6, 2017
Source:Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research
Summary:The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic.

The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic. With the help of a climate model, researchers from the Alfred Wegener Institute have demonstrated how this process took place, allowing us for the first time to understand more accurately how Atlantic circulation, as we know it today came about. The results of the study have now been published in the journal Nature Communications.

Every year, ca. 3,300 cubic kilometres of fresh water flows into the Arctic Ocean. This is equivalent to ten percent of the total volume of water that all the world's rivers transport to the oceans per year. In the warm and humid climate of the Eocene (ca. 56 to 34 million years ago), the inflow of freshwater was probably even greater. However, in contrast to today, during that geological period there was no exchange of water with other oceans. The influx of saline Atlantic and Pacific water, which today finds its way into the Arctic Ocean from the Pacific via the Bering Strait and from the North Atlantic via the Greenland-Scotland Ridge, wasn't possible -- the region that is today completely submerged was above the sea at that time.
...
But did the "Arctic Really Great Lake" ever freeze? (from Wikipedia):
Climate
The Eocene Epoch contained a wide variety of different climate conditions that includes the warmest climate in the Cenozoic Era and ends in an icehouse climate. The evolution of the Eocene climate began with warming after the end of the Palaeocene-Eocene Thermal Maximum (PETM) at 56 million years ago to a maximum during the Eocene Optimum at around 49 million years ago. During this period of time, little to no ice was present on Earth with a smaller difference in temperature from the equator to the poles. Following the maximum was a descent into an icehouse climate from the Eocene Optimum to the Eocene-Oligocene transition at 34 million years ago. During this decrease ice began to reappear at the poles, and the Eocene-Oligocene transition is the period of time where the Antarctic ice sheet began to rapidly expand.

But when did it go from freshwater "Lake" to salty "Ocean"?   The Middle Eocene Arctic was dominated by freshwater (from Early to middle Eocene history of the Arctic Ocean from Nd-Sr isotopes in fossil fish debris, Lomonosov Ridge, 2009), although
Evidence of intermittent exchange between the Arctic and adjacent oceans is also preserved in the deeper water (Nd) isotope signature of the fish debris, although limited connections during the Eocene probably restricted this exchange. We conclude that an active year-round Arctic hydrologic cycle, along with eustatic and tectonic controls on oceanic exchange, must have exerted significant control on the evolution of Eocene Arctic Ocean water column structure and the isotopic composition of early and middle Eocene fish debris reported on here.

Possible shallow marine connections existed between the Arctic and Tethys (via western Siberian Seaway/Turgay Strait), North Atlantic (via the Norwegian-Greenland Sea and the Labrador Sea), and the Pacific Ocean (via proto-Bering Strait). NA, North America; A, Asia/Siberia; Gr, Greenland; E, Europe. Middle Eocene connections are uncertain, and exchange with Tethys may have ceased by early middle Eocene time
Arctic ice is healthy for children and other living things.

Re IJIS thread - why is polluted with non IJIS related speculation?

Re contrarian betting :
Big boys make seriously big money betting contrarianingly. They only bet contrarianingly when they have insider info or they themselves helped manufacture the wild swing to one side of true value. They never bet unknowingly.
Small boys who bet contrarianingly on the wild hope of getting rich loose their shirt long before they wipe their arses with 100$ bills.
If most of the mpst knowledgeable people on this forum are very fearful for the state of the ice in September, better not to risk betting that we'll be running adventure marathons to the pole...

Climate scientists seeking opinion of stupid idiot to complete study

OTTAWA – Scientists are nearing completion on another planet-wide study on climate change, but say they require the opinion of a “real stupid idiot” in order to complete their work.

“We’ve spent months conducting research and analyzing the data,” explained Dr. Naomi Prashad. “So we’re nearly there. We just need the assistance of a total brow-furrowing goddamn dolt to point out any shortcomings in our work.”

The Jimmy Dore Show was in a bit of a slump recently, with Dore incessantly ranting about the same things (and cursing even more than usual). His ego played up a little as well. And it was less funny. It has to be funny, that's crucial. Not just for the viewers, but also for Dore's team, because it's really difficult to do things if you don't get some fun or satisfaction out of it.

I've been watching some videos from the past days, and it's really good stuff again.

Good to see you again, Ivica. I had to think about you the other day. The song you post would also fit in here.

PS the audience needs singing lessons  ;)

Amnesia Force is strong these years, so let me repeat a bit of what SIDD put earlier:

The economy of communion, if it wants to be faithful to its charism,
must not only care for the victims, but build a system where there are ever fewer victims,
where, possibly, there may no longer be any.

I'd like to use this on twitter, with h/t to you if that's OK?

Current mainstream view on the Universe of/by species struggling on how not to destroy own nest/mother_planet:



Near the end of Chapter 1:
Ignorance is the natural state of mind for a research scientist.

--

The world's IQ seems to be in the decline. Estimate for 2050 from 2004. article, read from table there says: 86.
But according to article from today (test results of 550,492 individuals in 123 countries..., 36 comments currently) - we are already there?

Coming today:



Presentation of the Dialogue:
http://press.vatican.va/content/salastampa/en/bollettino/pubblico/2017/10/27/171027a.html
Representatives of the Church and high level European political leaders will participate in the Dialogue, to contribute to a constructive reflection on the fundamental challenges for the European project.
...
• Climate change and the resulting need to change our non-sustainable lifestyle in the medium term. Connected to this is also the problem of the costs of ecological change and their distribution.
...
this event is not a “classic congress”, but rather a dialogue; following an introductory discussion on the topics listed by Pope Francis in his speech at the award of the Charlemagne Prize:
• “Integration” (with fractures and lacerations both within and between EU Member States);
• “Dialogue” has been typical of our western democracies;
• “Capacity to generate” (what form of economic model we will need in the future).

** i forgot this (my bolds):

" But we believe that EU citizens, with their different experiences, their different expectations and with their rich and diverse capacities, should be brought back to the centre of “Project Europe” and be able to be its agents."

Vatican Radio

Pope Francis was presented with the keys to a brand-new Lamborghini Huracan on Wednesday by officials from the luxury car maker.

The special edition car, however, will be auctioned off by Sotheby's in London and the proceeds given to four charities in Pope Francis' name.

Pope Francis blessed the car and signed the hood after receiving it in front of his Casa Santa Marta residence.

Sporting the papal colors - white with yellow-gold detailing - the Lamborghini Huracan's base price usually start at 183,000 euros but the specially-made papal car should bring far more at auction.

"Our Living Planet From Space"
Life. It's the one thing that, so far, makes Earth unique among the thousands of other planets we've discovered. Since the fall of 1997, NASA satellites have continuously and globally observed all plant life at the surface of the land and ocean.
