❄️ We had such a great time at @_Arctic_Circle 23 presenting EU funded #H2020 projects. Many thanks to all EU Polar Cluster members who joined us at our booth, as well as to all attendees interested in European #polarresearch who stopped by!🙌

Historically, much of the gender gap in earnings could be explained by differences in education and occupational choices. However, this year’s economic sciences laureate Claudia Goldin has shown that the bulk of this earnings difference is now between men and women in the same occupation, and that it largely arises with the birth of the first child. #NobelPrize

Where does that leave us? (2) - #GulfStream transport is large, and contributes to gyres and overturning. - #AMOC is smaller, but dominates heat transport. Review from Jackson et al. (2022) on AMOC since 1980 shorturl.at/dnFY6

Major difference #2: Heat transport At 26°N, the #gyre moves little heat. ~0.2 PW (0.2 x 10^15 watts). The #AMOC transports almost all the heat (1.2 PW), even though it only claims a fraction of the #GulfStream. Johns et al. 2011 (shorturl.at/wADKV)

Major difference #1: #GulfStream v #AMOC The gyres are nicely described by theory. We can write an equation for them. As long as the wind blows and the earth rotates, a gyre will exist. A #GulfStream is essentially unavoidable. Image from Stommel 1948 (shorturl.at/dfvR0)

Where is the #GulfStream in all this? It’s part of both the horizontal and vertical circulations! It contains the western boundary current of the gyre and the northward limb of the #AMOC in the northern subtropics. Image from IPCC FAQ 9.3 shorturl.at/ehLR6
Schematic representation of circulation in the Atlantic where the Gulf Stream (along the east coast of the USA, flowing northwards) splits somewhere offshore of the Atlantic, with one 'branch' flowing northwards as part of the AMOC and the other branch flowing southwards as part of the return circulation of the subtropical gyre.

The overturning goes up and down. It’s a vertical circulation (seen in the yz-plane), and described in a integrative sense (across x-dir) where the net effect is to ‘tip’ the waters over (= overturning). Only found in the Atlantic. (Ok, the A in #AMOC gives it away.)
